WHY DO WE NEED
The majority of the national building regulations introduce recommendations with reference to limit noise levels, according to EN 12251:2007, to prevent those cases where the building occupants, especially in family houses or apartments tend to reduce the fan speed or even turn off the ventilation in cases of too high ventilation noise.
An effective acoustic attenuator for MCV & HRV systems tested in accordance to the regulations EN 13141 and EN 7235.
- Less noise of the Ventilation unit and between rooms.
- More installation oportunities.
- More installation options than with metallic silencers.
- Lower height. Only 55 mm high!
- Absolute compatibility with our ductwork systems.
- Maximum airtightness thanks to the connection system Tubpla® StancoFix.
Following the ventilation unit.
Inmediately before the extract/supply valves.
The self-balanced exhaust grilles, with flow regulators included, are designed to keep a constant air flow regardless of their underpressure.
They can be used in MCV & HRV systems, for extraction of foul air of
KITCHENS, BATHROOMS and TOILETS. They also can be of simple or double flow. They are also available with acoustic insulation to ensure compliance with acoustic regulations.
Mechanically adjustable valves for extraction and insufflation of MCV &
HRV systems. The flow regulation can be managed by rotation of the central shutter.
The humidity sensitive extract grilles include a device which is activated depending on the humidity level of the ambience.
HUMITY SENSITIVE WINDOW INLETS
The principal task of the window inlets is to introduce new air in the main rooms of the house: living room, dining room and bedroom. They are placed on the top of the window or in the outer wall. They are used in simple flow MCV systems. The self-balanced window inlets can be identified by their nominal flows under pressure of 20 Pa. Air inlets of 15, 22, 30 or 45 m3/h.
The type and quantity of window inlets will be determined by the national building regulations in application to each building situation.
They are also available with acoustic insulation to ensure compliance with acoustic regulations.
The principal task of the flow regulators is to balance the air distribution ductwork when their length generates differences between the flow needs and the real flow. They are also a solution to use when we want to install a decorative grille instead of an extract/supply valve.
They generate a nominal flow at low pressure (50 to 200 Pa), and at high presure (100 to 650 Pa), and they are placed inside the duct or the MB connector (LK extract grille) or MTM (TM terminal).
The flow regulator can be installed embedded inside the duct. It includes a joint to guarantee the airtightness.
The minimum distance between the flow regulator and the associated
extract grille must be less than the diameter in extraction and three times the diameter in insufflation.
It is necessary to keep the flow sense, which is indicated into the flow regulator label for extraction. In insufflation we have to invert the position.
