It is extremely easy to install and requires little maintenance. Its robust design and powerful performance make it the most popular device in the industrial sector.

1 of 5The complete CNC production of the housing components guarantees maximum accuracy of fit and consistently high quality.
The design meets the highest aesthetic standards.
The fine adjustment by means of a grid enables the air discharge angle of the CONVERGO® nozzle to be set precisely.
3 of 5The discharge opening of the patented CONVERGO® nozzle extends almost the entire length of the appliance without interruption. This ensures maximum efficiency when several appliances are installed in series.
4 of 5The large nozzle cheeks ensure a clean air flow.
An additional flow profile divides the air flow into a primary and secondary jet. The increased outlet velocity in the primary jet leads to an even greater penetration depth.
