Rotary Vane Pumps

Accessories

Oil Mist Eliminator - Exhaust Filters
The oil mist eliminator and the exhaust filters retain the oil vapors which would otherwise be expelled into the atmosphere during pumpdown and gas ballast operation.

Some models feature an oil return line to allow condensed oil or fluid to return to the pump reservoir.

Foreline Roughing Traps
Varian’s new traps are designed to prevent the backstreaming of mechanical pump fluids. Copper and stainless-steel gauze inserts are designed to reduce oil backstreaming.

Molecular sieve inserts are available for applications where it is desirable to increase water vapor pumping speed while eliminating backstreaming above the trap.
