Description
Description of round adjustable exhaust vents
- The vents are in diameter 125 to adapt to the vent connection tees.
- Material: ABS thermoplastic polymer + elastomer gasket
- Colour: White RAL 9016
- Maximum extraction rate: 70 m3/h at 3m/s
Advantages of round adjustable exhaust vents
- Adjustable airflow: optimization of airflows per room
Regulations for ventilation sizing
The ventilation device must be able to extract the following flows:
How to balance double flow ventilation flows?
There are generally two ways to balance the flow rates:
- With self-adjusting vents in the service rooms (WC, bathroom, other water rooms):
Flow rate calibrated at 15 m3/h or 30 m3/h and double flow rates in the kitchen. The other rooms are equipped with manually adjustable vents. Goal :
- comply with the decree of March 24, 1982 on the minimum and maximum flow rates to be extracted from service rooms (see table above),
Advantages :
- easier to balance,
- maximum regulatory flow rate to be extracted in the kitchen is more easily reached.
Disadvantages:
- self-adjusting valves require a pressure of at least 50 Pa to operate correctly,
Precaution:
- it is necessary to check with the flowmeter or the pressure sensor the correct functioning of the vents.
- With manually adjustable vents in all rooms:
The opening of the mouths can be more or less closed according to the desired flow.
Advantages :
- flexibility of flow rates and general over-ventilation of the building,
- less network load losses.
Disadvantages:
- balancing requiring equipment (flow meter) and specific methodology.
- this solution generally offered by foreign manufacturers does not allow compliance with the order of March 1982 on the minimum and maximum flow rates to be extracted.
