Stationary Single-Stage Compressor Buyer's Guide

Some homeowners need air compressors occasionally for inflating tires, running brad guns and air brushing.

But what about the folks who need compressed air consistently?

If you fit this bill, you're in luck.

Stationary single-stage compressors are perfect for people who frequently run air tools in their garage or workshop.

Horsepower
Single-stage compressors are available in 2-5 horsepower (HP). Your air requirements will dictate how much HP you will need to effectively utilize your compressor.

While a 5 HP compressor isn't necessarily better than a 2 HP model, the extra power does mean you can create more CFM. This will allow you to run more heavy-duty air tools or multiple air tools at once. Make sure the compressor you select can produce enough CFM to run the tools in your arsenal.

Voltage
For single stage compressors there are three voltage options: 120/240v, 208-230v or 230v. The most important factor in your decision will be what type of electricity you are already wired for.

Standard homes have 120/240v wiring. Choosing a compressor with this capability will be easiest because you will not have to install any new electrical wiring. If you don't already have 208 or 230v wiring installed in your home or garage, you'll need an electrician to set it up to support the higher voltage.

Pumps
The pump on a compressor is arguably the most important piece of the machine, as it keeps it humming and pumping out compressed air. If the pump isn't designed for the application you are using it for, it can overheat and die.

To prevent this look for a single-stage compressor with a V-design pump. This style will minimize vibration, improve cooling and subsequently extend the life of your compressor.
