Vacuum pumps - Elmo Rietschle

Q: What's an oil-free vacuum pump, and when do I need one?

An oil-free vacuum pump, dry rotary vane, rotary claw, or screw, releases no trace of oil into the process. It's required in food, pharmaceutical, and medical applications, where any contamination must be ruled out.

Frequently Asked Questions

What’s the difference between a rotary vane and a liquid ring vacuum pump?
Rotary vane pumps (dry or oil-lubricated) deliver deep vacuum in a compact footprint. Liquid ring pumps handle condensable vapors and wet processes better, though typically at a shallower vacuum level.

What’s an oil-free vacuum pump, and when do I need one?
An oil-free vacuum pump, dry rotary vane, rotary lobe, or screw, releases no trace of oil into the process. It’s required in food, pharmaceutical, and medical applications, where any contamination must be ruled out.

What vacuum level fits my application?
The required vacuum level depends on your process: vacuum hold-down, drying, pneumatic conveying, or a centralized system. Our application engineers assess your needs at no cost to recommend the exact technology and model.

Does Aircom offer rental or service for vacuum pumps?
Yes. Flexible rental is available for temporary or emergency needs, in addition to permanent solutions and OEM parts and service.
