The Elmo Rietschle range 


The F Series are robust and economical single and multi stage radial blowers for vacuum and pressure operations. They come in a wide variety of sizes and can be used for both suction and pressure in industrial processes. These fans are especially suited to the packaging and paper industries where they can be used for extracting dust and fine material. 

Variable frequency drives are available for optimised efficiency.

Side Channel 

G Series side channel blowers are a reliable and proven technology. They have provided flawless performance day after day for decades and have been a tried and tested solution for many industries. The G Series is available in a wide performance range up to 3,000 m³/h and differential pressures of up to 1,000 mbar. They offer flexible and powerful performance and come in a virtually maintenance free and lightweight design. 

Liquid Ring

The L Series of liquid ring vacuum pumps has been specially designed for extreme conditions. Wet and humid processes can lead to limescale, abrasion, and other issues that, over time, will downgrade the performance of the pump. The L Series has been engineered with these specific challenges in mind. Stainless steel shafts ensure they are corrosion resistant, offering safe ongoing performance, whilst ceramic coating ensures the pumps do not calcify due to fluid deposits.


Primarily used in applications that need coarse or fine vacuum for handling gases and vapours, rotary lobe vacuums offer robust performance. The R-VWP is dry running with no grease or oil in the compression chamber. 


The C Series dry claw pumps generate contact free vacuum efficiently and economically. They rely on innovative technology that focuses on the principle of internal compression in the claw design. This provides significant energy savings for customers whilst offering higher efficiency compared with traditional blower designs that do not offer internal compression.

Explosion proof and ATEX compliant models are also available. 


The S-VSI is a state-of-the-art oil free screw pump that is efficient, reliable, and also offers extremely low life cycle costs. As it’s dry running, it guarantees no process contamination and no pollution caused by pump operation. In the pump housing, two rotors (both timing gear synchronised) turn in opposite directions. The gearbox is lubricated and cooling is achieved through the continuous flow of coolant through the pump housing. Elmo Rietschle pumps feature high vapour and liquid tolerances and low rotational speed ensures low noise and low vibration levels during operation. 


Rotary vane technologies are available in both dry running and oil lubricated models. Available in a wide performance range, oil free rotary vane pumps feature maximised cooling air pathways, heat resistant materials, and sound reduction covers. Lubricated models have been time-tested and are typically used for generating vacuum.
