Top 10 Best 2-Stage Air Compressor Models

Picking the best 2-stage air compressor should be easier. Two-stage air compressors have two cylinders. The first cylinder feeds air to the second one that compresses the air further. The second cylinder usually has a tank pressure up to 175 PSI.

The benefit of the dual-stage air compressor is the extra air stored in the tank. This allows you to work longer or use your tools longer.

2-Stage Air Compressor Buying Guide

Tools Demand

Most air tools require at least 90 PSI to run. However, to maintain 90 PSI, you need a compressor that has a higher shut-off pressure.

Many two-stage compressors can handle this.

They build up to 90 PSI in the first stage and up to 175 PSI in the second. Smaller compressors with a single-stage shut off at around 135 PSI and can maintain a 100 PSI pressure at most.

This may seem like it could get the job done but the pressure drop might not be enough to power your tool, especially if you need it for long periods.

Storage and Portability

Air compressors come in two different design options. You can have either piston air compressors or a portable air compressor.

Piston compressors are stationary and can’t be moved. Piston air compressors come in two types.

You can choose a dual-stage air compressor a single-stage compressor. A dual-stage air compressor will work best with larger projects or when you need large amounts of air for a long time.

Portable air compressors are ideal for construction sites or when you need to attach pneumatic tools.

You want to consider your storage options as well. Some people might only have a small space to house the compressor and can’t choose a larger one and vice versa.

Power Source

Air compressors have different power sources. The most common power source is electric. However, you can buy a gas-powered model too.

You might benefit more from a gas-powered model than an electric.

For example, you may need an air compressor for a construction site where you don’t have access to electricity.

Gas-powered models are usually industrial grade and more heavy-duty.

With an electric 2 stage compressor, you need to consider how much voltage you will need.

Household compressors generally use 110 -120 volts but a 2HP engine might require higher like 220–240-volt outlets.

Overall, electric compressors are quieter, weigh less, run continuously, and easier to use than gas-powered compressors.

Tank Size

Air compressors come with various tank sizes and positions too. Mounted tanks will require that you choose a size.

What size will you need? This will depend on the type of work you plan to do with the compressor.

The tools that you’ll connect to it will matter too. Tank sizes are measured in gallons. If you plan to use pneumatic tools for a short period of time, you won’t need a big tank.

Larger jobs that will take a long period of time to complete will need a bigger tank.

CFMs

CFMs measure the flow of an air compressor. CFMs will vary depending on the PSI of an air compressor.

Air compressors will have different CFMs for any PSI value. When you go to purchase an air compressor, you want to compare the models.

Check the CFMs at the same PSI values to ensure you’re purchasing the right ones.

The last thing you want is to take home a compressor and you have a different CFM than what you need for the job.

Horsepower

Air compressors have ratings on them to indicate what they can do. Horsepower is no exception.

The horsepower of your air compressor will show how much power the unit has.

Depending on what you plan to use your air compressor for, you may not need ones with high ratings.

Low rating horsepower will work well for people that need to use it for smaller projects.

However, if you need to use the compressor for industrial purposes, then you want a higher rating.

Features

It may not seem like there’s much room for customization, but air compressors do have options. You might choose to buy an air compressor that’s belt-driven or direct-drive.

Depending on what you plan to use the air compressor for, you might want one that has an oil-free pump.

Oil-free pumps won’t require as much maintenance as ones that rely on oil. You may want an air-cooling system or an adjustable exhaust. You will decide which features you want, if any, based on your needs.

What is a Two-stage Air Compressor?

A 2 stage compressor features two piston cylinders. Each one has a different size. The air first goes through a compression stage. The air passes through a heat exchanger.

The heat exchanger cools the air before it travels to the second cylinder. When the air is cooled, it reduces the work need to compress it in the next stage.

In two-stage compressors, the air travels through both chambers.

The second chamber pressurized the air to the required amount. It then travels down into the tank where it waits for the user to use the air.

2 stage air compressors have twice compressed air. The extra compression makes compressors work more effectively because of the quicker recovery time. It also will allow you to use more tools for a longer period of time without breaks.

There are two most common types of 2 stage compressors. Reciprocating (piston) or rotary. Both are positive displacement compressors.

A reciprocating 2 stage air compressor has two cylinders: low-pressure and high-pressure. The second cylinder is smaller to further facilitate compression.

The first stage of a reciprocating compressor takes the air down to the low-pressure cylinder by a suction system with an inlet filter.

The air gets compressed with a piston and cools the heated air. The second stage takes the cooled air and moves it to the high-pressure cylinder with a shorter piston to further compress.

Then, the pressurized air is cooled and moves to the storage tank where it waits for you to use it.

A rotary 2 stage air compressor has several types: screw, scroll, vane, and lobe. The screw type has been the most popular with scroll types becoming more popular in recent years.

A screw type works like the reciprocating compressor except they have helical rotor screws instead of a piston.

A scroll type compresses gas using two inter-fitting scrolls where it has two levels. The opening and closing ports allow air to bypass a portion of the scroll.

Single-Stage vs. Two-Stage Air Compressor

https://www.youtube.com/watch?v=e9nNRf20IE8

Single-stage air compressors have pistons that drawdown. The air gets sucked through the filter element and past the intake valves.

From there, it goes into the cylinder.

When the crankshaft rotates and the pistons are pushed upward, the air compresses as it’s forced through the exhaust valves.

Then, it travels through the discharge tube and check valve. It heads down into the tank where it sits until you need air.

Two-stage air compressors have a large low-pressure piston that draws down. The air gets sucked through the filter element and past the intake valve to the cylinder.

When the crankshaft rotates, and the low-pressure piston pushes upward. The air compresses for the first time as it’s forced through the low-pressure exhaust valve.

The air then travels through an intercooler to the high-pressure side of the pump. It’s drawn into the cylinder and compressed a second time.

From there, it travels through the discharge tube and checks the valve. It will travel down to the tank where it stays until you need air.

There are cases when you’d want to use a single-stage over a two-stage air compressor. Single-stage models work great for individual users or small crews. It will benefit anyone that does framing, sheathing, roofing, or trim work.

Larger construction crews or users who need large amounts of air for extended time should choose a two-stage air compressor.

Pros for a Single-Stage Compressor:

• Cost less

• Weigh less

• Electric models draw fewer amps

Cons:

• Limited usage because of heat

• High friction level

Pros for a Dual-Stage Air Compressor:

• More efficient

• Runs cooler

• Delivers more CFM

Cons:

• Requires high maintenance

• Heavy and bulky/not easily portable or storage

Two-Stage Air Compressor Components

2 stage air compressors have six major components. These components work together to make the compressor run.

Cylinder

A 2 stage air compressor has two cylinders. One is called a low-pressure cylinder and the other a high-pressure one.

Connecting Rod

The connecting rod connects the crankshaft and piston. The piston moves because of the movement of the connecting rod.

Piston

Each cylinder has a piston. The piston compresses air into the cylinder. It moves upward and down into the cylinder.

When the piston moves upward, it sucks the air into the cylinder. When it moves downward, it compresses air.

Inlet Valve or Suction Valve

The inlet valve sucks air from an external source into the compressor cylinder.

Outlet Valve

This connects to the high-pressure cylinder. It discharges compressed air.

Intercooler

The intercooler reduces the temperature of the air before it sends it to the high-pressure cylinder. It’s responsible for cooling the air.

So, What’s The Best?

The 2-stage air compressors I have reviewed here are the best in terms of their reliability, durability, and functionality. An air compressor can last you years and make your work life or DIY projects easier.

Single-stage air compressors won’t handle what you need unless you’re completing the most basic tasks. You’d be lucky if it can even power a single air tool. Two-stage air compressors offer more in terms of power.

The market is full of air compressors you can choose from. However, you can easily see that the Quincy QT-54 is the best 2-stage air compressor. The incredibly long lifespan and the iron flywheel design make the compressor energy-efficient and durable.

Additionally, the aluminum head and finned tube intercooler increase longevity and rid heat faster.
