G-Series Rotary Lobe Blowers
(Roots-Type Lobe Blower)
These tri-lobe, belt-driven blowers provide greater efficiency with less blow-by. Our G-Series models use larger rotors and bearings than many competitors, allowing for a slower operating speed. This results in more efficient heat dissipation, a longer service life, reduced maintenance and lower vibration and noise levels.
Comes as a complete package with all necessary components included.
Features
- Conservative operating speeds for long service life and reduced vibration
- Durable cast iron casings and rotors
- Tri-lobe design rotors for increased efficiency
- Large ball bearings for extended life
- Large timing gears provide efficient tolerance
- Various motor frame types and voltages to suit application requirements
Optional Arrangements
- Conventional base mount or space-saving “dual deck” arrangement
- Water-cooled units for higher pressure/vacuum levels for more demanding applications
- Cabinet enclosed unit for sound and attenuation
2-stage units for higher pressure and vacuum requirements
Components Included
- Intake filter/silencer with replacement 10 micron paper cartridge
- Pressure or vacuum relief valve
- Pressure or vacuum gauge
- Vee belt drive with Osha compliant guard
