Every rotary screw manufacturer offers a base mounted screw compressor. The smaller sizes are great for tight installations or replacing a failed screw compressors on a tank mounted unit. Larger compressors (typically 25 hp and above) are generally all base mounted due to the weight and size of the compressor.

Manufacturers of Rotary Screw Compressors offer different features, our experts generally promote screw compressors that offer these features for the following reasons; wye delta starting (energy saving feature), TEFC motors (totally enclosed, fan cooled), Phase Protection and Sound Enclosures.

Top air compressor brands are; Atlas Copco, Quincy Compressor, ELGI Compressor, Champion Compressor, Chicago Pneumatic Compressors, Hertz Compressors, Ingersoll-Rand Compressors, KORE Compressor, Mattei Compressors, Saylor-Beall Compressor and Sullair Compressors.

Not sure how much air your compressor puts out.  The rule of thumb is 3.5 CFM per 1 hp.

What are People Buying?

People are all asking what people are buying.  Here is a quick snapshot of what industries are buying; Granite fabricators 10 - 30 hp compressors), Automotive (5 - 15 hp compressors), general manufacturing (5 - 500 hp), Pharmaceutical (lub & non lub, 3 - 100+ hp),  remediation (3 - 25 hp compressors), medical (3 - 50 hp compressors) and many more.  

Why buy new vs. used air compressors? Remember, there is a reason why someone traded in their used air compressor; potential compressor repairs on a used compressor could far exceed the cost of a new one.

Who Will Service My Air Compressor?

Compressor manufacturers offer a service network to support their products. Once a machine is purchased from Compressor World - one of our experts will forward the local service centers information. All warranties and future service (preventative maintenance) can be done with from the manufacturers service center.

I found the right rotary screw compressor, what else should I know before buying this compressor?

Once you have chosen the right rotary screw compressor for your facility, you will need to know the right voltage. You have either single or three phase power and the options would be:

Single Phase (3, 5 & 7.5 Horsepower)

• 208/1/60 or 230/1/60

Three Phase (All)

• 200-208/3/60
• 230-240/3/60
• 460-480/3/60
• 575-600/3/60

We also ask what pressure you want the compressor set for, the standard pressure in the industry is 125 PSI but in some cases customers ask for 150 or 175 PSI. For every 1 PSIG change from rated pressure, the brake horsepower will change 0.5% from the rated BHP. Think about decreasing your header pressure and start saving energy.
