High-Performance, Highly-Efficient Venturi Air Movers
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 (see efficiency performance charts).
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 (see performance/efficiency charts).
