Regenerative Blowers

Regenerative BlowersRegenerative blowers are a compact and efficient alternative to large multi-stage or positive displacement blowers. Gasho can meet your application needs with regenerative blowers in numerous configurations, developed to meet specific application requirements.

AMETEK ROTRON® has long been a leading name in regenerative blower technologies, with product benefits including quiet, maintenance-free, and oil-free operation. Whether industrial, chemical processing, or environmental, each variety of regenerative blower has specific features to meet particular application needs.

Regenerative Blowers Features

Industrial

  • Rugged cast aluminum housing, cover, impeller, and muffler tower
  • Removable cast iron flanges bolted to a sheet metal manifold
  • TEFC motors on single-ended models, ODP motors on all double-ended models
  • Carbon steel shaft and zinc plated hardware
  • Permanently sealed motor bearings for 20,000-25,000 hours life

Chemical Processing

  • “Chem-Tough™ Teflon anodize (surface conversion) inside and outside on housing, cover, impeller, and heavy duty cast manifold
  • Teflon® lip seal in a stainless steel case standard for leakage containment to 25 cc/min or less
  • Chemical Duty motors with 303 stainless steel motor shafts
  • Stainless steel hardware throughout
  • Nickel plated flanges and muffler retainers

Environmental Processing (EN)

Same as the industrial blowers with additional features:

  • Heavy duty cast aluminum manifold
  • Our spark resistant housing, cover, impeller, muffler tower, and manifold are vacuum impregnated
  • Teflon® lip seal in a stainless steel case standard for leakage containment to 25 cc/min or less
  • Explosion-proof motors standard and available in a variety of world voltages
  • All metal-to-metal surfaces are sealed with RTV sealant
  • Various UL explosion-proof listings
