The unmatched performance of the COPPUS Jectair® HP is recognized throughout the industry. Compared to older air horns, the patented air mixing chamber of the Jectair® HP converts the air flow with a ratio of 40:1 and saves up to 26% of compressed air.

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 projected by 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 speed through the horn-shaped diffuser.
