Competitor Blowers

COMPETITOR PLUS rotary lobe blowers are designed to be interchangeable with equivalent sizes of competitive models. They are rated up to 15 PSIG (1.03 bar g) discharge pressure or 16” Hg (-540 mbar g) dry vacuum.

COMPETITOR SL blowers include splash oil lubrication at both the gear end and drive end of the blower. Splash lubrication provides for longer bearing and seal life through improved heat dissipation versus grease lubrication.
Many sizes of COMPETITOR SL blowers are available with MD-Kinney’s unique noise reduction technology with tri-lobe rotors specially designed for maximum displacement and special porting to significantly reduce noise.

Equalizer Blowers

Designed to be interchangeable with equivalent models from competing manufacturers, EQUALIZER DF rotary lobe 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.

Designed to be interchangeable with equivalent competing models, EQUALIZER RM rotary positive blowers offer many distinct advantages when compared to other brands, such as helical gearing to reduce noise, rotors with integrally cast shafts, positive, locked-in end clearances to prevent internal contact and polished sealing surfaces.
