- If you are going to buy your first compressor, you will probably get confused initially. Our Best Quiet Air Compressor reviews will help you to select the right Compressor to buy. There are so many models with various specifications that you might think about picking the right model for you is an extremely complex and long process. But there is one thing you need to know – you can make it much easier for you. How? In this section, we will give a number of cues on how to choose the best air compressor for your needs.
- The very first thing you need to know is what you need an air compressor for. Do you want to use it for home applications, your small contractor company, or large business? What set of tools will you be using with your air compressor? What will be the frequency and duration of your works? Answering these and other similar questions will set the starting point in your searches.
- Regardless of the type of air compressors, they all have two primary characteristics – pressure and capacity. Pressure is either expressed in psi or bar and capacity is usually expressed in CFM (cubic feet per minute), cubic meters per hour, or liters per second. What do these impact exactly? Simply put, the pressure is “how strong” your air flow will be and capacity is “how much” compressed air can a compressor’s tank pump out at given pressure in a given period of time.
See this full video to get a conscious knowledge about Installing a Shop Air System
- Keep in mind that capacity is NOT how much a given tank can hold in liters or gallons. So if you see an air compressor with a 200-liter tank, don’t get confused. The capacity of the air flow is much more important as it shows how efficiently the air compressor can supply your air needs. Remember that the capacity of the tank alone doesn’t mean anything.
- To understand how much capacity you need, add up the requirements of your all air tools and machines you have. That sum is the capacity your tools will need if all used at the same time (not usually the case).
- The pressure you will need depends on the kind of tools and/or equipment you will be using. To get an idea of what you will need, look into the specifications of your instruments. Manufacturers usually put the required air pressure in the descriptions of their products, so you will be able to generally know the pressure you will need your future air compressor to provide you with. Aim at the pressure required by your biggest tool. If you don’t have tools yet or otherwise don’t know what pressure you will need, aiming at 100 psi should be safe for you as most hand tools and machinery operate at 100 psi.
- Now that we are done with capacity and pressure, let’s talk about types of best quiet air compressors. There are two most common and popular types out there today – reciprocating and rotary screw air compressors. There are other types such as scroll, turbo, and rotary vane compressors, but as they are designed for more specific applications, we will focus on reciprocating and rotary screw models only.
- Those types are quite different, so understanding your needs is crucial for you to get the right type. By the way, all compressors on our today’s review are reciprocating as you can only find a quiet machine among them.
- What type of compressor will you need for your tools and tasks? For simplicity, we will now show general characteristics and suitable spheres of application of these two types.
Reciprocating air compressors compress air with one or more cylinders/pistons. With these models, air is compressed with the pistons reciprocating (moving up and down or back and forth). We won’t look into the mechanism too deep, so let’s instead focus on its features:
- Low to very high pressure (7-1000 bar or 100-15000 psi).
- Generally Low capacity.
- Usually Low power consumption.
- Designed for intermittent use.
Reciprocating air compressors are much more compact, lightweight, and quiet compared to rotary screw compressors. That’s caused by their less powerful motors (up to 10 hp. (7 kW)).
Reciprocating models are best for:
- Workshops, small businesses, or construction work.
- DIY or home applications.
Their suitability to the aforementioned applications is quite obvious as it would be inappropriate to get a huge compressor for your small house needs. So buying a reciprocating air compressor for similar needs is a much better choice.
Rotary screw compressors
Rotary screw air compressors compress air by two screws (rotors) running in opposite directions inside the housing. Air is compressed by getting trapped between the rotors. As for its features, they are directly opposite to the ones of reciprocating air compressors:
- Low pressure (7-15 bar or 100-215 psi).
- High capacity.
- High energy consumption.
- Designed for continuous use (even 24 hours a day every day).
Rotary screw models are big, which makes them not suitable for small needs. The power of their motors goes up from 10 hp. to more than 1000 hp. (700 kW). These air compressors should be used in bigger businesses which will use them constantly.
⇒⇒ See this full video to Choose your Best Air Compressor
Which one do you choose?
Reciprocating air compressors are great if you are not going to use your model continuously. Even if you have some bigger tools, you should purchase a bigger reciprocating air compressor rather than rotary screw one if you won’t use it constantly.
Another advantage of reciprocating air compressors is their high pressure. If you need high pressure and won’t be using your compressor too frequently, you should get a reciprocating model. At last, reciprocating air compressors are much quieter, more compact, and consume less power compared to screw rotary models. See useful question and answer about choosing air compressor.
If you don’t need quietness, compactness, low power consumption, and high pressure, you should look for a rotary screw air compressor. They are the perfect choice for those requiring continuous airflow at lower pressures. Just keep in mind that rotary screw compressors don’t tolerate standing still as they easily get rusty. Know the management system of a compact air compressor.
After we have generally understood what each of these two types does and who should get one or the other, it’s time to look into them one by one to understand what you will need to look for in the case of both types. Let’s start with reciprocating air compressors!
What to look for when buying a reciprocating air compressor?
As we already mentioned, reciprocating compressors are great for those who need:
- Low noise level.
- Less energy consumption.
- Compactness and lightweight.
- High pressure.
- The possibility of intermittent use.
There are three basic types of reciprocating air compressors:
- Single-stage units.
- Two- or multi-stage units.
- Duplex units.
In the case of single-stage reciprocating air compressors, the unit has only one piston/cylinder and the air is compressed in 1 stage. Single-stage compressors are cheaper and more simple in design compared to the other two types. Their capacity and pressure go up to 20 CFM and 140 psi (10 bar) respectively.
Single stage reciprocating compressors are good for home or light commercial uses. However, multi-stage compressors will be a better selection for commercial application.
Two-stage models have two pistons/cylinders (one low-pressure and one high-pressure). The low-pressure piston pumps up the air to about the half of end pressure. The air then gets cooled and compressed fully by the high-pressure cylinder.
Double-stage units have more capacity and deliver higher pressure. With two-stage reciprocating air compressors, the capacity and pressure reach up to 50 CFM and 175 psi (12 bar) respectively.
These models are much more suitable for smaller commercial or industrial uses such as workshops, automotive shops, or other small businesses.
A Duplex compressor is just two separate compressors paired with one tank. Those compressors are typically single-stage. The capacity and pressure of duplex units go up to 70 CFM and 175 psi (12 bar) respectively.
You may ask, what’s different between two-stage and duplex compressors. Duplex units usually have bigger capacity while two-stage compressors produce higher pressure. Another advantage of duplex units is that even if one of the compressors breaks down, you will be able to continue to use it with the same pressure. It’s just the capacity that will get cut in half.
Besides the aforementioned types, compressors can be oil-free or oil-lubricated (or oil-flooded). Oil-free compressors are more expensive, require more maintenance, and are noisier. You will only need an oil-free compressor if you need cleaner air for such jobs as painting. So if you don’t really need an oil-free reciprocating compressor, don’t worry about it too much.
Another characteristic of reciprocating air compressors is their power supply. In this regard, you can either find an electric or gas powered air compressor. They both come in the same design (single- or dual-stage, or duplex).
Gas powered air compressors are ideal for work sites with no electrical power. A downside of these compressors is that they have a higher noise level and produce exhaust fumes. Keep in your mind that not all gas-driven compressors are portable as some models can weigh up to 600 lbs. (272 kg). You should choose a gas-driven compressor if you are going to have issues with electricity on your job sites.
What to look for when buying a rotary screw air compressor?
A rotary screw compressor is a perfect choice for larger businesses and constant use. But how do you get a rotary screw air compressor with the right pressure and air capacity? To start, we will examine a couple of cases and give tips for each of them.
- First air compressor. In this case, you will have to find out the sum of air consumption of all your air equipment first. That will be the capacity (CFM) you will need. As for the pressure, look for the tool requiring the highest pressure among the tools you have or will be using. That will be the pressure your rotary screw air compressor will have to deliver.
- Replacement for an old rotary screw compressor. If your old compressor’s pressure and capacity were sufficient, look for a new best air compressor with the same features. Don’t forget that you might need a slightly bigger unit as you may expand your business in the future.
- You need more capacity. How much capacity will you need? Apply the same method – calculate the total of the air consumption of your equipment. This works if you have added a new tool to your set and discovered that you need more capacity from your compressor. You can either get a new compressor or buy an additional unit to put alongside your main compressor. If your old compressor is reciprocating, don’t forget that rotary screw units don’t like inactivity. Besides, remember that you might need to expand your company!
Rotary screw compressors come in different shapes, sizes, and with a variety of accessories. You shouldn’t buy those options which you don’t really need. But how do you know what you should get? Let’s take a look at a couple of accessories of rotary screw compressors!
Integrated air dryers and filters. Some models come with integrated air dryers and filters. They are actually quite useful as compressed air is wet and dirty by nature, especially with oil-lubricated compressors. Clean air will keep your equipment safe from premature breakdown. Keep in mind that dryers and filters cause the pressure drop in the system, resulting in more energy consumption to compensate for the pressure drop. With these accessories, your electricity bill can increase by additional hundreds or thousands of dollars over the lifetime of your unit.
Electronic condensate traps. Best Quiet air Compressors usually come with mechanical traps. If you don’t want to bother with them, get an electronic condensate trap. This can make your life much easier actually. Condensate is one of the most important maintenance issues with rotary screw compressors, so an electronic trap will add some easiness into the task of keeping water away from the system.
Variable speed drive (VSD). This device matches the output capacity to your actual needs, but it will only be really useful if your compressor constantly runs under different loads. Otherwise, it will be inefficient as it will increase the energy consumption.
Without an aftercooler, the compressed air leaving the compressor is usually too hot for most air tools. Besides, aftercoolers remove big amounts of water from the air, which would otherwise stay in the compressed air and create condensate inside the unit after cooling.
At last, energy consumption is crucial to businesses using rotary screw air compressors. You should always get a more energy-efficient model even if it is more expensive. That will surely save thousands of dollars in the long run. Over the lifetime of a unit, purchase cost will be only 10% of your total expenses. 15% will be maintenance costs, and the rest 75% will be energy expenses. Besides, be careful with its accessories as they can cause more energy consumption without really helping with your job.
So how do you choose the right compressor? Remember what we said about capacity and pressure? It applies not only to reciprocating compressors but rotary screw compressors as well. Pair it with the features of these both types of air compressors, don’t forget about your needs, and you will be able to get the best air compressor you can.
Benefits of Buying the Products
As we already mentioned, reciprocating air compressors are the best choice for home use or small businesses. But what are the exact benefits of such air compressors? Let’s examine them!
- Reciprocating air compressors are much more compact and lightweight compared to rotary screw units. That is quite obvious as their tank capacity is significantly lower! That makes them a great choice for those seeking for easy-to-transport and –store air compressor!
Low noise level
- You certainly don’t want to have an excessively noisy device at your home or small workshop. Once again, reciprocating air compressors deliver noise levels suitable for your home. Your neighbors won’t get too annoyed when you do some works at your home or workplace with your best quiet air compressor! You should definitely get a reciprocating compressor if you don’t want to have a too loud machine at your home.
- Lightweight means convenient transport. You surely cannot carry around a 100-pound compressor easily! For those looking for portability, there are some pretty light models out there! Besides, some compressors come with wheels and/or handles to aid with their transportation! This makes reciprocating air compressors much more suitable for carrying than bulky and stationary rotary screw compressors!
- Reciprocating air compressors deliver much higher pressure compared to rotary screw units. If you use some big instruments requiring a lot of pressure at your home works or in your business, getting a reciprocating air compressor is a right thing to do.
Low energy consumption System
- What you certainly don’t need to get with your air compressor for your home or small business are astronomical bills for energy. You need something more modest and energy-efficient for your small needs. As reciprocating compressors have less powerful motors, they consume significantly less energy than rotary screw units. A great reason for getting a reciprocating air compressor!
You can use reciprocating air compressors intermittently
- You don’t need to worry about constantly running your reciprocating compressor. Just drain the compressor’s tank and store the unit until you need it for your next job!
Great for starting a small business
- Thinking about starting your own workshop? If you will be using air tools (but not continuously, otherwise, buy a rotary screw model), get a reciprocating compressor as it is cheaper, more compact, more quiet, more energy-efficient, and delivers higher pressure. Use it until you discover that its features aren’t enough for you so you purchase a more powerful one or just switch to rotary screw compressors.
Frequently Asked Questions
How often should the oil be changed with oil-lubricated reciprocating air compressors?
Generally, you would need to change the oil approximately every 3 months. That will depend on your model and the frequency of use.
When should the air intake filter be replaced?
Assuming that you use the compressor 3 days a week, you should clean it on a weekly basis. Replace the filter if you notice any tears or holes or the debris is becoming harder to clean out.
What type of oil should be used with reciprocating compressors?
You should use non-detergent oils suitable for use in reciprocating compressors. Do not use detergent oils as they will foam and cause excessive oil carry over past the piston rings. That results in the compressor not getting lubricated enough.
When would I need a rotary screw air compressor?
Rotary screw air compressors work better under constant load. If you slowly move towards more frequent and even continuous work, you should start thinking about a rotary screw air compressor. That will probably never happen if you use your machine at home only, but small businesses can expand in the future. Besides, rotary screw compressors will be more suitable for you if you don’t need as much pressure but need more capacity.
