PRESSURE-OPPERATED DAMPER PITCH 50 FOR WALL OVERVIEW AND TECHNICAL DATA TECHNICAL DATA: Damper and grille frame (if present) Extruded anodized aluminium, width 25 mm, rounded edge. Blades In aluminium with pitch 50 mm, fixed with hinges on nylon wrist inserted on frame. Blades of grille (if present) In extruded anodized aluminium with 20mm pitch, fixed with wrist in a nylon self-locking lane inserted in the frame. Transversal reinforcement: all dampers having size B over 1000 mm. Counter frame Rigid in steal. Mounting on the wall Without screws but clips and counter frame or in the traditional way with screws in wall or channel. Finishing In natural aluminium. PRESSURE OPERATED DAMPER FOR VENTILATION WSI OVERVIEW: The WS series dampers are used to maintain overpressure or under pressure in premises or apartments; they can be used for in air conditioning, ventilation and heating systems. This type of damper can be supplied with an extraction grille with a 20 mm pitch or a net both already mounted. For the intake-model the net is replaced with a square mesh grille for external use, because of the higher strength and the better aspect.

PRESSURE-OPERATED DAMPER FOR DUCT OVERVIEW: The WCS series dampers enable the flow of air in a natural single direction when a difference of pressure between the two sides exits. The blades are free to move on the wrist enabling the flow of air. Once this is achieved the blades shut simply by with the force of gravity. CHARACTERISTICS: Frame : in extruded aluminium, 120 mm wide, made in 4 parts assembled together mechanically. Blades : in aluminium with pitch 100 mm (up to height 600 mm pitch 50 mm). Execution : with flanges for channel. Grille (on request) : in aluminium pitch 50 mm SIZES...

CONTROL DAMPERS PITCH 100 mm OVERVIEW TECHNICAL DIAGRAMS OVERVIEW : WM-10 control dampers are a new series of products from the WM series. The WM-10 series of control dampers are suitable for the application on square and rectangular ducts. The control of these dampers can be manual, electric or pneumatic, according to the needs of the ventilation system. The installation of these components allows the control of the air flow rate variation (VAV) or the pressure variation control on several kinds of plants. Specifically: WM-10 control damper is new in its type due to the innovative movement...

CONTROL DAMPERS PITCH 100 mm TECHNICAL DATA NSTALLATION PROCEDURE CHARACTERISTICS : Damper Mobile closing system mounted into an air duct, designed to control and close air flow. Mounting By screws through damper flange and duct flange or by selfthreading screws through damper flange and air-treatment unit panel. MOUNTING SYSTEM : Frame, materials and construction method The frame is manufactured in extruded aluminium and designed to withstand the lateral stress from to air pressure, and built with lateral frame to protect the drive gears. Damper mounted inside (figure n°2) or at the...

CONTROL DAMPERS 50mm PITCH OVERVIEW : The WM-05 series forms a new range do calibration dampers. These dampers are used in ventilation systems and for the regulation of the air distribution in the network. The regulation of the air flow is managed from a manual command able to regulate the blade inclination (WM-05C). In alternative the damper can be equipped with an electric servomotor that can be controlled by the individual themselves (WM-05P). With this scope, a version has also been designed with a control hinge, as shown in the diagrams here below shown. CHARACTERISTICS: Frame:...
