Variable Frequency Drive Field Kits

Variable Frequency Drive (VFD) retrofits are available for rotary oil-flooded and oil-free machines. The VFD retrofit is an external, stand–alone option making it easy to install and maintain. The VFD option provides the ability to exactly match the compressor's output to the capacity required by varying the speed of the main drive motor. This translates into distinctive benefits for the customer.


Energy Savings – by allowing continual operation at the desired pressure, the VFD can provide up to 35% energy savings compared to conventional cycling.

Utility Company Rebates – many utility companies offer rebates (sometimes as much as 100%) for plant energy savings (contact your local power company for details).
VFD allows the customer Variable Speed Operation which translates into Lower Cost of ownership – energy cost is the single largest cost in owning an air compressor, the VFD can save significant money for your customer.

Smooth start-up – the VFD is "soft starting" which allows for controlled acceleration and deceleration. The result is reduced stress on mechanical components and enhanced system reliability – all of which extend the life of the compressor. VFD allows precise pressure control and reduced noise level.
