Aluminum alloy air duct diffuser with Nylon mesh primary filter
1. Return air grille vent cover description
Construction:
· Frame: High quality extruded aluminum alloy(A6063) profile with
30mm flange as standard.
· Blades: Aerofoil blades in 45° from aluminum profile
· Blades spacing: 35mm as standard
· Support pipe: 8mm diameter aluminum pipe
Description:
The louver return air window is often used for suction and air
supply in the pipeline. At the same time, it can be equipped with a
herringbone gate (multi-leaf split control valve) according to the
actual situation to control the air volume or install the aluminum
alloy filter for supporting use. The blades can be divided into
horizontal and vertical, and can be flexed left and right or up and
down to control the airflow direction.
Surface Finish:
· Powder coated color finish as per RAL color----standard color:
RAL9016, 9010
· Natural anodized aluminum finish
2.Double deflection grille features:
1), single layer / double layer adjustable blade, can get different
air supply distance and different diffusion angle
2), can be used as air supply and return air
3), optional aluminum or iron production
4). Use with the regulating valve separately for the air supply
port
5), can be made into an openable structure for the return air
outlet, and used with the filter
3.Return air grille vent cover adhibition
1).Widely used in air conditioning system as air outlet, according
to the requirements, the air outlet can be prepared behind the
aluminum air flow control valve (Hue word gate), double louver air
outlet with two layers of vertical pages to adjust the horizontal
and vertical page angle, adjust Air diffuser surface, to change the
range, the air outlet frame width has two kinds of wide frame and
narrow frame, can be used for special requirements of the
ventilation system.
2). Usually installed on the pipe or side wall as a side air
outlet. The double louver air outlet has two movable blades with
adjustable angle. The short blades are used to adjust the spread
angle of the air supply air, and can also be used to change the
direction of air flow; The blades can make the supply air flow
attached to the ceiling or tilt down at a certain angle (when
heating the air). The outer blades of a double shutter air outlet
or the blades of a single louver air outlet can be parallel to the
