The right machine for low-pressure work.
Many low-pressure jobs are better served by dedicated vacuum or blower equipment than by a compressor run at low pressure, or an ejector.
Elmo Rietschle, part of the Gardner Denver group.
We also service equipment from Busch, Becker and Edwards, and give vendor-neutral technology advice.
- Lower energy use than low-pressure compressor or ejector systems, especially for continuous duty
- Longer service life and fewer breakdowns from purpose-built machines
- Oil-free dry-running options for food, pharma, medical and electronics
- Oils, filters, vanes and seal kits stocked for common makes
Four technologies, four series
| Technology | Series | Notes |
|---|---|---|
| Rotary vane | V-Series | Oil-lubricated or dry |
| Claw | C-Series | Dry, contact-free, internal pre-compression |
| Liquid ring | L-Series | For humid, wet or corrosive gases |
| Screw | S-Series | Dry, single-stage, high vacuum; claimed high water vapour tolerance and short evacuation times |
For flow below about 1 bar
Side channel
G-Series. Claimed virtually maintenance-free, with no lubricated internal parts.
Rotary lobe
For higher pressure differentials and pulse-free flow, with frequency control available.
Speed adjustable via inverter. Figures are the vendor’s own claims from the J&J website.
Where vacuum and blowers earn their keep
Vacuum

- Vacuum forming
- Degassing
- Drying
- Medical and lab use
- Suction handling in printing
- Freeze drying
Blowers
- Pneumatic conveying
- Wastewater and aquaculture aeration
- Air knife drying
- Combustion air
- Textile and paper handling
- Biogas
Planned maintenance and reactive repairs on all major makes

Should I use a compressor for a vacuum job?
Often a dedicated vacuum pump or blower is a better fit than a compressor run at low pressure, or an ejector, particularly for continuous duty.
Which technology suits wet or corrosive gases?
Liquid ring pumps (L-Series) are the option for humid, wet or corrosive gases.
Describe the duty and we will recommend a technology.
