Durable Clean Room Ventilation Decorative Return Air Filter Grille Single / Double Deflection

Custom air grille all kinds of hvac grilles and diffusers for ventilation system

1. Air grilles description

The single-layer adjustable louver tuyere is commonly used for suction and air supply in pipelines. At the same time, it can be equipped with a herringbone valve (multi-leaf diverging valve) according to the actual conditions to control the air volume or install aluminum alloy filters for supporting use. . The blades can be divided into two types: horizontal and vertical, and they can be flexibly moved left and right or up and down to control the airflow direction.

The double louver tuyere has two movable blades with adjustable angles. The short blades are used to adjust the spread angle of the supply air flow, and can also be used to change the direction of the air flow. The adjustment of the long blades can make the supply air flow adhere to the ceiling or declining. The angle (when sending warm air). The outer blades of a double louver tuyere or the blades of a single louver tuyère can be parallel to the long side or parallel to the short side, and can be selected according to the customer's requirements.

2. Air grille covers choice features:

1). Veneer tuyere adopts main control parameters such as tuyere type, material, specification, outlet wind speed, total pressure loss and airflow range.

2). The material of the tuyere is mainly steel and aluminum alloy.

3). Select the corresponding tuyere type according to the engineering characteristics, the type of airflow organization required, the adjustment performance, and the air supply method.

4). Determine the size of the required tuyere within the allowable wind speed range of the tuyere neck (or inlet and outlet section of the tuyere) according to the required air volume [supply or discharge (return) wind]. If the tuyere size is determined according to the tuyere wind speed (generally 2~5m/s), the effective area ratio of the tuyere should be taken into consideration (usually 30%~60%).

5). Check the main technical performance of the selected tuyere, such as range, pressure loss, noise indicators, and wind speed and temperature difference in the work area.

6). Determine the layout and installation method of the selected tuyere and the connection with the air duct.

3.Double deflection grille features:

1), double adjustable blade, can get different air supply distance and different diffusion angle

2), can be used as air outlet

3), optional aluminum or iron production

4), can be used with the regulating valve

4.Air griller 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 long side or parallel to the short side , can choose according to the customer's request.
