Every rotary screw manufacturer offers a tank mounted screw compressor. Tank mounted air systems are generally used for smaller applications (8.6 - 125 CFM) and the major benefit is the ease of installation and space.

You buy a tank mounted compressor to save space and reduce the cost of installation.  Compressor fabricators install compressors on 60, 80 and 120 gallon tanks with a hp range between 5 and 30 hp, larger compresors are not tank mounted because of the weight and size:abcd

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.

What Else... I found the 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

Who Makes the Best Tank Mounted Screw Compressor?
Their are many compressor manufacturers that make tank mounted compressors.  Tank mounted compressors should be 3, 5, 7.5, 10 or 15 hp compressors, anything larger is awkward and top heavy.  For example, what if you were servicing a 25 hp air compressor on a 200 gallon tank, you would need a step ladder to change the inlet flter or do a oil change, that's not very safe.  Plus the weight of the compressor on a 120 or 200 gallon tank can cause extra stress on the tank welds which could cause the air tank to fail.  Ingersoll-Rand, Quincy, Chicago Pneumatic and Atlas Copco make a solid tank mounted air system.  

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.
