Regenerative Blowers

Why are regenerative blowers so popular? What makes them so much better than other air moving machines? Regenerative blowers are virtually maintenance-free and are much more efficient than an equivalent air compressor.

Single-Stage and Dual-Stage Regenerative Blowers

Operating Principles: The impeller rotates inside the blower housing, pulling air in through the inlet, or vacuum side. The impeller then accelerates the air or gas inside the housing until it is fully pressurized, and discharges it through the exhaust outlet, or pressure side.

Single-stage blowers are the most common type of regenerative blower; with these blowers, air travels around the internal air channel once and is then exhausted out to the application. Dual-stage regenerative blowers can provide a lot more pressure or vacuum than their single-stage counterparts because the airflow is channeled back around the impeller for a second rotation before being exhausted. This causes the air to be more laminar which greatly increases the velocity pressure of the conveyed air.

What about maintenance? The motor shaft is the only moving part, which spins the impeller directly; it does not come in contact with the housing at all and is, therefore, "wear-free". Pre-lubricated bearings are the only wearing parts, and these days, bearings have some of the lowest failure rates of any mechanical item in existence.

Air Knife Drying / Air Knife Blowoff

An air knife system is meant to blow off any remaining substance (such as dust, water or any other liquid or debris) from products on a conveyor. These products have typically been washed or have been dipped in a liquid that needs to be dried for packaging. This is where an air agitation blower comes into play. As the product moves down the conveyor it passes through the airstream to be dried.

Waste Water Treatment / Tank Aeration

Microorganisms in an aquatic system require oxygen to breakdown waste material. This process is just one step in waste water treatment that ultimately results in a clean water source. When using our regenerative blowers and diffusers for aeration, we can assure maximum oxygen transfer efficiency in any waste water system.
