Your Air Compressor may be the biggest energy consumer in your facility and installing a rotary screw air compressor with a VFD can help reduce your consumption dramatically when sized properly. The VFD regulates the flow and pressure by adapting the motor speed to the demand. No energy is wasted and there is no unnecessary equipment wear.abcd
How do I size my VFD Compressor?
VFD Compressors should be applied where they are running between 20-80% of the compressor full load.
What else do I need?
We highly recommend installing a line reactor. Some compressor manufacturers require this to maintain the factory warranty.
Rebates
We also recommend you contacting your local utility company to see if they offer any utility rebates for energy efficient equipment.
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:
Three Phase
- 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.
