Designed to be interchangeable with equivalent models from competing manufacturers, EQUALIZER DF rotary blowers offer many distinct advantages such as higher pressure capability (18 PSIG on most models), true, drop-in replacement even to the point of matching the port connector bolt patterns, and helical Gearing to reduce noise.

Helical Gearing
Timed with hardedened, precision helical gears, keyed to the rotor shafts (NOT taper fit spur gears as offered by all other manufacturers, which have greater backlash, and can slip and lose timing). Helical gears are quieter, reducing mechanical noise.
Double Row Ball Bearings
For increased strength compared to single row bearings offered by competing brands. This feature increases bearing life by as much as 50% compared to competing brands.
Rotors with Integral Shafts
Equalizer DF™ blowers are available in two-lobe or tri-lobe variations. The tri-lobe variation offers reduced pulsation and lower noise levels. The two-lobe variation is ideal for processes with heavy contamination. For vibration free operation all rotors are dynamically balanced. Shafts are integral to the rotors, which prevents loosening over time.
Positive End Clearances
Eliminates the risk of shifting end clearances when installing or removing drive components.
Polished Sealing Surfaces
All shaft surfaces in contact with sealing members are polished to reduce seal wear and risk of leakage.
Individually Tested
Every Eqaulizer DF™ blower is factory tested to assure you of the highest quality. While some manufacturers perform only sample testing, we go the distance to insure that your blower meets our rigid ISO 9001 registered quality standards.
