High Pressure Industrial Blowers We provide single stage, two stage, and four stage regenerative blowers for pressure and vacuum applications. Pressure capabilties extend to 15 psig. and vacuum capabilities to 24"Hg. which flow to 825 cfm.


Regenerative Blowers are the ideal solution for moving large volumes of air at high pressures or vacuums. Unlike positive displacement compressors and vacuum pumps, regenerative blowers "regenerate" air molecules through a non-positive displacement method to create vacuum or pressure. In the world of air handling equipment, regenerative blowers are probably the least understood of today's technologies, but when system parameters fall within the range of a regenerative blower, it can be the most cost effective method for producing pressure or vacuum.


Regenerative Blowers : are also called side channel blowers or ring compressors, terms that refer more to their physical construction. The more common name regenerative comes from their basic operating principle, as discussed below.

High Pressure Industrial Blowers
The majority of blower failures are due to improper installation and / or operation. Because there are so few moving parts, there is not much that can go wrong. Regenerative blowers have close internal tolerances between the impeller and housing, and it is important to not allow foreign material to enter the blower. Debris that is ingested by a blower can cause a catastrophic failure as it may become wedged between the impeller and housing which will cause the blower to lock up. A filter should always be purchased with a blower to prevent debris from entering the blower. A 10 micron filter is usually adequate to prevent such a failure from happening. Over pressurization can also cause a catastrophic failure. Some blowers can be "dead headed" (zero airflow through the blower) while other models (usually ¾ HP models and above) must have air passing through the blower to cool it. If air does not pass through the blower, heat will build up causing the impeller to expand at a faster rate than the blower housing. Eventually the impeller will lock up with the housing causing the blower to fail. A relief valve (either vacuum or pressure) will prevent over pressurization and will allow air to pass through the blower. Most blower manufacturers offer filters and relief valves as accessories for their blowers.
