AERZEN GMA 12.5 HV - REBUILT

AERZEN GMA 12.5 HV Roots Vacuum Blower - REBUILT

The blowers made by Aerzener series HV have been designed for conveying air and neutral gases and are especially used in industrial High Vacuum technology. With a total of 19 sizes the blowers cover theoretical nominal intake volume flows from 180 to 97,000 m³/h and pressure ranges from 10^-3 mbar abs. up to approx. 200 mbar abs.

Examples for the various fields of application:

• Coating technology chemistry
• Process technology metallurgy / construction of melting furnaces
• Packing industry central vacuum plants
• Helium leakage detection units
• Manufacture of lamps and tubes
• Drying technology
• Machine construction
• Electronics
• Automobile industry

Features:

• Three lobe rotors.
• Cylinder with pre inlet channels to cancel internal pulsations.
• Helical cut timing gears, hydraulically expanded onto their shafts for accurate timing of the rotors.
• Piston ring labyrinth seals with neutral chambers for oil free conveying.
• Cast iron end covers to provide strength and prevent oil leaks.
• Splash fed oil lubrication at the drive and non drive end to give long bearing and timing gears life.
