Why use a Regenair® Regenerative Blower? Features and Benefits Standard Motor Mounted Models • Rugged construction of cast aluminum or cast iron, depending on model size • UL and CSA approved motors; TEFC on singleended models, OPEN on dual-ended models. Permanently sealed ball bearings incorporate new polyurea grease that extends bearing life and offers superior resistance to washout, rust, and corrosion. Integrated mufflers on single-ended models minimize operating noise Explosion-Proof Motor Series • UL and CSA approved explosion-proof multi-voltage motors with thermal protection • Double...

Regenair® Regenerative Blowers Performance Overview Catalog Group The Gast Performance Difference Specifications The specifications listed are that of a unit at sea level with an ambient temperature of 70 °F (21 °C), operating with normal electrical current conditions. The figures stated in this catalog are nominal approximations for models without accessories. Intake filters and exhaust mufflers, and the accumulation of contaminants in them during operation, will decrease the flow of air as well as the achievable pressure. The units that we list in this catalog are a small portion of what we...

Blower System Design Tips In order to utilize your regenerative blower most efficiently, proper system design is essential. The most important thing to recognize is that by utilizing large diameter plumbing, friction losses in plumbing can be greatly reduced. Here are some guidelines to use when setting up your blower system: 1. The plumbing should at least be the same size as the blower port or ideally one size larger (example - blower has ports that are 1-1/2” NPT, plumbing should be 2” NPT). The plumbing should remain this size until it has reached the location of the work area. 2. Plumbing...
