XXL discharge air box for varied usage

We manufacture the XXL discharge air box for the international market according to the latest fire safety regulations. Usage locations are areas that are heavily laden with hot, dirt and grease-charged air in workshops and kitchens.

  1. The pipe and motor fixtures are specially designed to specific customer requirements.

  2. The edges are sealed off from adverse, external influences through the design.

  3. The circumferential seal protects the interior, containing the fan wheel and motor, from the aggressive circulating air.

  4. The separated fronts ensure savings on materials and are also very service-friendly.

  5. The central front piece has been designed to be extra stable for holding the motor.

  6. The welded high-performance fan wheel is low-noise, efficiency level-optimised, energy-efficient and exceeds the latest standards by a considerable margin.

  7. For easier handling during shipping and installation, the XXL discharge air boxes can be transported by crane.

If your product also has to withstand adverse external conditions, we are the partner you have been looking for. Get in touch with us.
