Installing a Variable Speed Drive on your air compressors can drastically reduce the amount of energy your compressors consumes. If you are looking to reduce your utility to your plant, consider installing a VFD compressor in your system.

Contact Your Local Utility Supplier To See if You Qualify for A Rebate

Many utility providers offer a prescriptive rebate program for energy efficient compressors. NSTAR & National Grid offer large rebates for compressors under 100 Horsepower without doing a intensive compressed air audit. Contact one of our compressed air experts and let us point you in the right direction.

Sizing Variable Speed Air Compressors

Operating a VFD under 20% and over 80% can actually cost you more in energy as well as cause damage to your compressor. Your VFD uses an average of 6-7% more energy, when your operating in the upper range of the compressor output, you lose any potential energy savings. When operating within the lower range, the compressor may run cool which could cause moisture build up in the bearings, which could cause premature failure. That said, you should size your VFD air compressor so it runs between 30 and 80% of full load.

Longevity & Flow

Vane compressors have an expected life of 100,000 hours without wear. Regarding the flow, the typical rotary vane compressors tend to be more efficient because they have less blow by or less internal air leakage. The vanes move freely and are in contact with the internal surface of the stator, so the seal is near perfect.
