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...

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...

Typical Applications - Imagine what you can do with air, We offer cost-effective solutions to blower applications for both OEMs and end-users. Gast's Regenerative Blower line of products are designed and built to meet the changing needs of industry and are ideally suited for a number of blower applications. These are ex- amples of many applications where Gast's Regenerative Blowers are widely used. PRESSURE APPLICATIONS Vacuum is often used to open, hold, and close bags in filling Pond Aeration Pond aeration is done for two basic reasons. One is aquaculture, where large numbers offish are "farmed"...

then call Gast VACUUM APPLICATIONS Automated Cutting Lasers, water jets, and knives are all precision tools for cutting - a wide variety of materials automatically. These computer driven machines use vacuum to hold materials being cut in place. Product Feeding Vacuum force is used to automatically stack product as it is received or to move the product from one process to another. Soil Vapor Extraction Contaminated soil is often treated usually gasoline or other hydrocarbons, out of the soil with Dust and Chip Collection Vacuum power is used to collect dust and/or chips from saws, mills, and other...

(See above curves) Some blower manufacturers advertise vacuum performance in CFM Inlet Air - measurement of the suction of air at a specific temperature at the inlet port and a specific discharge pressure at the exhaust port, which can be perceived as enhanced performance over Free Air Flow rated blowers. Therefore, we are also providing the following vacuum performance for Gast...
