The Jet-2's direct drive innovation eliminates the need for the belts, pulleys, tensioners, and spindles used by the industry for the last 40 years to power centrifugal blowers.
The belts and supporting components have long been a source of many industry complaints.
Bob Brady, a mechanical engineer who has incorporated centrifugal blowers in many applications over the last 20 years, summarises: "End users are constantly replacing worn belts and failed spindle bearings, often requiring line shutdown".
JetAir's patent-pending design reduces the number of components found in competing belt-drive blowers from an average of 40 parts to less than 10.
Dan Snyder, VP of Development at JetAir says: "We believe the direct-drive blower is the next generation solution to high maintenance and inefficient belt drive systems".
JetAir's direct-drive blowers are simple in concept and elegant in design, incorporating technology advancements in motors, bearings, variable frequency drives (VFD), and aero design.
The motor shaft is directly coupled to the turbine or impeller with speed controlled by the VFD.
Belt-drive systems use a constant-speed motor with inefficient pulleys of various diameters linked to an impeller-spindle assembly by a belt in order to achieve the target speeds.
Snyder continues: "Added advantages of JetAir's design are increasing mechanical and electrical efficiencies while reducing overall system size by about 40%".
"Eliminating the belt-drive transmission combined with an innovative aero design results in huge gains in efficiency".
"Field test results indicate overall energy savings of up to 40% over belt drive systems due to efficiency increases".
JetAir's Jet-2 direct-drive blowers are certified UL and CE approved, meaning they meet the stringent standards of the USA and European Union for quality, dependability and safety.
