PRESSURE-OPPERATED DAMPER PITCH 50 FOR WALL

OVERVIEW AND TECHNICAL DATA

PRESSURE OPERATED DAMPER

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.

TECHNICAL DATA: Damper and grille frame (if present)Extruded anodized aluminium, width 25 mm, rounded edge.BladesIn 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 frameRigid in steal. Mounting on the wall

PRESSURE-OPERATED DAMPERFOR DUCT WCS

SEIRESOVERVIEW

)) )

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

CONTROL DAMPERS

PITCH 100 mm WM-10SERIES

OVERVIEWTECHNICAL 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:

a) HVAC plants regulationb) modulated calibrationc) modulated or total closing

WM-10 control damper is new in its type due to the innovative movement transmission system of gear-drives, the non existent friction of the mechanism, the assembly method of the materials used, the particular requirement of air flow control with the wing design of the movable blades and the integrated interchangeable controls, allow for a diverse integration and installation in ventilation systems.

CHARACTERISTICS :

DamperMobile closing system mounted into an air duct, designed to control and close air flow.

Frame, materials and construction methodThe 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.

FlangeManufactured with 30 mm height.

Blades, materials and construction systemThe blades are manufactured from extruded aluminium with a particular profile in order to be a better sealing surface and a good strength to air pressure.

Transversal reinforcementPresent on all dampers with B dimension wider than 1300 mm.

Finishing

MountingBy screws through damper flange and duct flange or by self-threading screws through damper flange and air-treatment unit panel.

MOUNTING SYSTEM :

Damper mounted inside (figure n°2) or at the beginning or at the end of the air duct (figure n°3 and 4) fixed by the frame flange to the duct flange. The control damper can be mounted on the floor or ceiling (figure n°5).

FinishingExtruded aluminium.

Gear drive, materials and construction systemOpposed rotation gears made from PBT with 30% of glass fibre. The gear drive is closed and protected on the frame. The materials used allow a use between a a temperature range between - 40 °C and + 130 °C.

CONTROL DAMPERS

50mm PITCH WM-05SERIES

OVERVIEW

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: extruded aluminium, 30 mm flange, 65 mm thick, built in four parts joined by mechanical assembly.Winglets: drummed to a wing profile in extruded aluminium extruded 50mm internal axis.Mechanism : transmission system composed by the movement of the interlocking gears.

CIRCULAR CONTROL DAMPERSWR5

SERIESOVERVIEW AND

TECHNICAL DATA

OVERVIEW :

WR control dampers are a new series of products used for control on circular ducts. This series is available with models WR5 WR6 WR7 WR8 for application on all HVAC plants with manual, pneumatic or electric control. The installation of these components permits the control of the air flow rate variation (VAV) or the pressure variation control on several kinds of plants. Specifically:

a) HVAC plants regulationb) modulated calibrationc) modulated or total closing

Circular control dampers have a different construction according to different installation. Indeed they can be mounted by coupling (figure n° 1) and by flanges (figure n° 2).

IRIS REGULATION DAMPERWMIRSERIES

OVERVIEW

CONSTRUCTION : The WMIR iris dampers are equipped with a supporting structure with a series of regulation blades, activated by turning a nut or lever (80 diameter). The dampers also have a regulation scale together with sockets for differential pressure gauges. The structure and the blades are made of hot galvanised steel, while the other components are made of plastic. The connections have a gasket on the outside used to ensure the joint is sealed.

USE :The WMIR iris dampers are the ideal solution for precise, quick measuring and regulation of flow rates. For ducts that carryacid fumes or agents that are particularly corrosive, these iris dampers can be used.

Made of AISI 316 stainless steel, upon specific request.

Type of flow disturbance

± 7 %

Safe distance L, for a measuring tolerance of

± 10 %

≥ 2 D ≥ 1 D

≥ 4 D ≥ 2 D

INSTALLATION :The WMIR iris dampers can be riveted in position. For vertical installations, the weight of the ducting positioned on top of thedamper must be fully supported. In addition, the iris damper must be positioned sufficiently far away from branches, unions and any element that can cause disturbances to the measuring of air flow rates. In this case, we recommend installing the units at the safe distance, as indicated below.

≥ 4 D ≥ 2 D

≥ 2 D ≥ 2 D

In general, the measuring accuracy for an undisturbed flow is around ± 5 %. In the latter case however, the safe distance between the diffuser and the damper is intended to allow the diffuser to work normally, despite the damper being added to the system.

MEASURING THE FLOW RATE :The regulation blades make up an ideal measuring diaphragm, allowing the air flow rate to be measured easily and reliably. The flow rate value is determined by measuring the differential pressure Dpm via connection to a differential pressure gauge.Once the Dpm value is known, the regulation diagram is used to determine the corresponding flow rate. The regulation diagram is clearly shown on the damper close to the regulation nut and includes a set of curves that relate to the various regulation positions. It is important to note that the diagrams on the damper are used only for regulating and not for selection -the selection data is given on the previous pages.

ACOUSTIC CHARACTERISTICS :

The acoustic power levels for the duct, for each octave band, are obtained by adding the correction factor, Koct for the octaveband (see table above) to the total acoustic pressure level Lp10A [dB(A)] using the following equation:

LWoct = Lp10A + Koct

The correction factor Koct for octave band is equal to the mean value for the field in which the WMIR series iris regulation isused.
