COPPUS® Jectair and Hornet HP
High-Performance, Highly-Efficient Venturi Air Movers
Model: Jectair and Hornet HP
The unmatched performance of the COPPUS® Jectair HP is recognized throughout the industry. When compared with older-style air horns, the patented air mixing chamber of the Jectair HP produces up to 26 percent savings on compressed air consumption.
Operating Principle:
Compressed air or steam is admitted to the Jectair through a single inlet connection in the housing leading to the mixing chamber. The air or steam jetted from the nozzle creates a Venturi action which induces a large volume of surrounding air to enter the Jectair through the aerodynamic inlet bell. The air is then discharged at high velocity through the horn-shaped diffuser.
NOTE: Operating efficiency depends on compressed air volume and pressure.
