Side Channel Blowers

Air Energy Ltd are authorised distributors for a variety of companies within the compressed air and vacuum industry. Our network offers us access to a wide range of products, including the impressive Elmo Rietschle Side Channel Blowers. Side Channel Blowers can be used for both vacuum and pressure applications, they also require virtually no down time so can offer a very efficient service.

How Side Channel Blowers work

Side Channel Blowers operate by sucking in air/gas through the inlet channel, which them enters the machine. The rotation of the impellers gives momentum to the air/gas in the direction of rotation. Centrifugal force in the impeller blades accelerate the air/gas outwards, increasing its pressure. Kinetic energy is displaced with every rotation of the impellers, resulting in further pressure increase. The Pump narrows at the rotor, sweeping air/gas off the impeller blades and expelling it through the outlet silencer where it exits the blower.

The Elmo Rietschle Side Channel Blowers offer a High CFM capacity with moderate pressure or vacuum and are VFD compatible. They are robust to dust ingestion and offer quite operation, making them suitable for a large range of different projects. The impellers within the Elmo Rietschle G-series Blowers are designed for contract free compression, mounted directly on the motor shaft and the pumps bearings are arranged outside of the compression chamber to offer maximum operational reliability. The Elmo Rietschle Side Channel Blowers can be supplied in a wide range of sizes and performance capabilities. Currently, the smallest Regenerative blower (G-BH1 00) is a mere approximate 4.9 inches in height and width and has a depth of approximately 2.4 inches. At the other end of the spectrum, the Elmo Rietschle Blowers can offer a performance of 1,766cfm at 60Hz and  differential pressures up to 420 in H2O. Some of the range (2BH2) can offer up to 40,000 operating hours between service with virtually no maintenance and we can offer pumps with lower noise emittance and maintenance levels.


Elmo Rietschle side channel blowers are ideal for point of use applications and offer contact-less operation. They cover a many demanding applications; Woodworking, Plastics, Textiles, Medical & Dental Care, Electronic, Packaging, Food & Beverage, Environmental and Aquatic. There is a variety of more applications Side Channel Blowers can be used for and the examples listed are only a small selection of what they are capable of.

Side Channel Blowers are used in Woodworking for different applications, vacuum hold down and vacuum dust collecting. Vacuum is one of the most effective tools for hold down on CNC router tables. Hold down is important in ensuring safe processing; wood, plastic and metal can be held in place while routers cut out shapes accurately and efficiently. Side Channel Blower pumps can be used to suction off wood dust and shavings to then be directed to a collection bin for disposal or recycling. This is important for sale and efficient working within the woodworking industry. In-line filters are used to protect the integrity of the pump when used within this application and those similar.

Side Channel Blowers are greatly beneficial in sufficiently aerating H2O for Aquatic applications. Oxygen levels can be greatly increased using an Elmo Rietschle machine, substantial oxygen is essential to maintaining the health of aquatic life. The health of aquatic life can also in turn benefit other industries such as the Food industry. Sufficient oxygen levels within a pond/ tank can increase the number of fish it can accommodate; this can greatly benefit the Fish and Prawn supply industry. Adequate aeration also allows the fish to grow and multiply more rapidly which in turn significantly increases business assets.

Both Medical and Dental Care can benefit from the use of Vacuum and Pressure machinery in regular processes. Elmo Rietschle Regenerative Blowers are used with a Vacuum application in Dental practices to accompany Dental equipment. Vacuum is used for suction of liquids such as cooling water and bodily fluids when carry our Dental processes. Medical care can use both Vacuum and Pressure applications to benefit those who require care. Air beds are used to offer comfort for bed-ridden patients who are at risk of bedsores. Blowers can be used to assist with inflation of such beds, inflating individual air chambers whilst deflating others to vary the pressure applied to the skin and help prevent discomfort or bedsores to patients. The change to the air within the beds can also help position patients suitably and comfortably to receive treatment and care. Air Energy is pleased to offer support for the medical industry and assist with their ability to help others.

Many industries can also benefit from the assistance of Side Channel Blowers in Packaging. Vacuum bagged items use less space for transport and storage. Elmo Rietschle Blowers can be used for suction of air from Packaging to ensure a smaller surface area is used by items when Packing. Less space being required per package means maximum capacity can be used when transporting goods. This in turn ensures packaging is done in the most cost-effective way possible.

Pressure and Vacuum tools are a crucial element for many different industries to function accordingly. Side Channel Blowers are a piece of incredible machinery to assist with both applications.
