Air inlets Flash 3300
Product description

The Flash 3300 is made of high quality plastics, completely sectional and well insulated with 22 mm XPS.

The Flash steers the incoming fresh air before it enters the building. The air gets its direction through adjustable spoilers. The amount of air is regulated with a vertically moving slide. Steering and amount of air are seperated.

Because of this completely flexible steering the Flash is ideal for situations where high demands on the air control should be imposed e.g.:

  • houses wider than 20 meter
  • obstacles in the air way like construction bars
  • no air through nests
Technical data

Pay attention!

The position of the spoilers has a big impact on the capacity of the air inlet. The picture below illustrates this for the Flash 3300. Therefore Tulderhof advices to calculate with 10 Pa under pressure.

The numbers mentioned above are valid when the spoilers are in the “normal’ position. These sizes are examples; if you need another size please contact us. The F-3300 is made of plastic and has a standard size. All other Flashes are made of the highest quality plywood and therefore available in every size.
