Valve air supply Mini "Deltafan"(1100-1800м3/h)

ToLAPAN air flow Mini "Deltafan"(1100-1800м3/h). Vacuum valve air inflow.

Opens automatically at power on of the fans. With protective grille. with a Cover for closing in the winter.

Used in the device non-return valve serves to prevent the ingress of external air into the room, with a disabled fan. At the time of starting the fan the valve opens due to the resulting pressure difference created by the fan, and remains in this position until the fan is running. The degree of valve opening can be adjusted. The device is equipped with a protective metal mesh to prevent ingress of foreign objects in a ventilated room. The device itself has the appropriate form. The air enters the device from below, which prevents the ingress of snow or rain into the room. When choosing the place of installation of the supply device should take into account the following:

• Preferably, the location on the Northern or Eastern side of the building.
• Do not place near sources of air pollution (e.g., trash, gigaspora of the gutters, exhaust vents).

Valve air supply Mini

The speed of the air supply device should be about 3 m/s. higher Speed entails an increase in noise and an increase in pressure loss. Using to the given velocity and size of the inlet 0,2x0,5 m, you can choose the appropriate performance fan, which works in conjunction with the device. The fan performance should be in the range of 1100-1800 m3/h.

The pressure difference under which the valve is fully opened can be adjusted and is 25-40 PA (the difference between the atmospheric pressure and pressure inside the room). The device is made on the basis of unsaturated polistirolo-glass resins, resistant to the ravages of the environment. Black color of the device. The device has a plug-in peredney frame that simplifies installation and mount on the wall.
