The blowers are heavy construction cast iron units which operate at conservative speeds for long operating life. The extra large housings allow for large ball bearings and better heat dissipation. The standard units are available in open frame construction or with cabinet enclosures for sound attenuation. These blowers are operable up 14.5 psig and offer improved efficiencies over regenerative blowers at pressures above 4-5 psig. End casings include timing gears in an oil bath. Bearings at both the drive and gear ends are in oil baths to ensure lubrication.
