WHY CHOOSE Airshield

  • Regulatory compliance : Standard NF ISO 15080 and M62-233
  • Adjustable : very low pressure drop in the air flow, and several systems can be mounted in parallel for high air flow
  • Simple : the screw/ring assembly is performed by shrink fitting the screw into the corresponding ring

DESCRIPTION

Airshield : Presentation

Airshield is an integrated ventilation penetration system built in to concrete walls.

The ventilation penetrations are each composed of two main elements, the ring and the helical screw:

  • The ring features flanges at each end for connection to the ventilation network.
  • The screw is assembled and shrink fitted into the ring in compliance with the standard. The assembly is fitted with sealed end caps and plugs on the flange internal threads.

On delivery, the penetration is ready to install in the structural form panels prior to casting the concrete. 

The assembly systems are made of steel grades that are compatiblewith those used for the production of the ring and the connecting flanges.

Airshield : Applications

Airshield ventilates a hot cell by providing uniform radiation protection through the structural walls.
