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
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.
|Spoilers normal||Spoilers up||Spoilers extreme|
|Surface – 1,570 cm2||Surface – 1,480 cm2||Surface – 1,150 cm2|
|10 Pa – 2,400 m3/h||10 Pa – 2,100 m3/h||10 Pa – 1,750 m3/h|
|20 Pa – 3,300 m3/h||20 Pa – 3,000 m3/h||20 Pa – 2,450 m3/h|
|30 Pa – 4,100 m3/h||30 Pa – 3,650 m3/h||30 Pa – 3,000 m3/h|
|10 Pa – m3/h||2,400|
|20 Pa – m3/h||3,300|
|30 Pa – m3/h||4,100|
|Width – mm||580|
|Height – mm||390|
|Depth – mm||60|
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.
The Flash 3300 has:
- a completely insulated slide with 22 mm XPS
- an option to make the slide spring-closed
- an option to make the slide of transparent polycarbonate
- standard a flange of 40 mm
- a very easy mounting, with a standard place for the roll
