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		Tuthill vacuum boosters are 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 M-D™ Vacuum Booster 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.

• Supercharging vacuum pumps for better system performance
• Increasing vacuum system capacities
• Reducing system ultimate pressures

Every M-D Vacuum Booster is backed by the Tuthill Vacuum & Blower Systems limited warranty:
