General

Dampers for different purposes are usedin a ventilation systemRegulating dampersare used to balance the plant so thatthe wanted air flow is achieved.

The damper blade is normally designed so that a certain flowof air can always leak through, even if the damper is closed.This makes the sensitivity to angle changes less than for ashut-off damper.

Dampers are available in both manual and automatic ver-sions. The manual dampers are adjusted when the installa-tion is commissioned, and are cheaper than the automaticones. On the other hand, manual dampers need many morehours of adjustment, and means of flow measurement. Forthis reason, some dampers have measuring nozzles. In largesystems, or where pressure variations occur, it is better to

use automatic dampers. These are also referred to as con-stant flow dampers.

Shut-off dampersare used to save energy, to prevent thespread of poisonous gas etc. These dampers often have rub-ber seals on the damper blade. The damper can either be de-signed as a straight piece of ducting, or as a T-piece toswitch the air flow from one duct to another. The blade is nor-mally either fully open or fully closed.

TightnessTwo types of tightness are applicable to dampers:

1. Tightness to the environment

This specifies the magnitude of the air leakage throujoints and leaks in the duct sides in relation to the ductsurface. This leakage is classified into tightness classesA, B, C and D. Most dampers can be used in installa-tions/systems which require them to maintain tightnessclass D. Please refer to the Safe section.Fulfils the demands of the standard EN 1751.

2. Tightness past a closed damper shutterThis refers to the amount of air leaking past the closedblade, in relation to shutter area. This relationship isclassified into five sealing classes 04. There is no tight-ness requirement for class 0. The classes 0 and 1 areregulating dampers. The highest class, tightness class 4,

refers to very tight shut-off dampers.Fulfils the demands of the standard EN 1751.

Tightness past the closed damper bladeand pressure classes

Motorized dampers

Dampers can be supplied ex works with actuators installed.Various types of actuators are available, both electric andpneumatic.

MaterialStandardBushings are made from polyamide. The bushings can with-stand constant temperatures of up to 150 C.

SpecialIf a higher corrosivity class is required, the dampers can besupplied with a polyester coating, or made from aluminium orstainless steel. The blades can be provided with silicone rub-ber seals for higher temperature operation. The dampers canthen withstand constant temperatures of 150 C and 200 Cintermittent. In these cases, please contact Lindab.

CE-labelingOur dampers with electrical shifting motor are regarded ascomponents of the duct system and need not to be sepa-rately CE-labeled. Their electrical shifting motor on the con-trary is a part of the electrical system and is CE-labeled.Assurance of conformity can be found at www.belimo.com.

Blade settingDRU and DSU dampers of dimensions 63160 are supplied

with their blades completely open, to facilitate adjustmentpreparations. Dampers of other dimensions are supplied withclosed blades to prevent transport damage.

Cleaning of duct systemMost dampers have components which obstruct the ductsystem to a greater or lesser extent, and thus obstruct or pre-vent cleaning.

Please refer to page 603.

Regulating damper DRU


DescriptionHas a turning, cut-off blade. The blade is stepless adjustable

090. The damper admits an insulation thickness of approx.

50 mm.

The blade is designed to generate a minimum of noise. The

noise is approx. the same as for a perforated blade. But the

blade is less sensitive to clogging since it lacks perforations.

Setting angle

= 0 = open blade, = 90 = closed blad

There is a separate assembly, measuring, balancing and

maintenance instruction for this product.

801000 fullfills pressure class A in closed position.

The cup at 80630 can be complemented with the special

insulation cup IK at insulation thicker than 50 mm.

dimensioning

The solid curves show the pressure drop, pt, over the

damper as a function of flow q, and setting angle .

The dashed curves give the A-weighted sound power data,

LWA, in dB to the duct.

Damper with flow meter DIRU


DescriptionThe damper DIRU with flow meter offers measurement ofthe air flow. DIRU has following characteristics: low noiselevel, centric flow, fixed measurement nozzles for accurateflow measurement and is equipped with regulating facilitieswhich can be fully opened, which means that you do notneed cleaning covers. It fulfils tightness class C.

The dimensioning graph are to be used to determine thepressure drop over the damper with flow meter and to giveinformation regarding the sound effect level at different set-

tings. When balancing the system the balancing graphsshould be used.

There is a separate assembly, measuring, balancing andmaintenance instruction for dampers with flow meter.

The damper blades forms a measuring flange which allowsflow measuring. By measuring the pressure differencebetween the measure nozzles, you can through the equationon the damper derive the flow q [l/s]. The setting value of thedamper and the correction factor (k-factor) is the samenumber which means that you do not have to read a graphsin order to get the k-factor from a setting value.

The air flow is regulated with a handle. 80630 fullfills pressure class A in closed position.

MaterialThe damper is made of hot-dip galvanized sheet steel.

InstallationConsider required straight distance after or before distur-bance, as mentioned on the card attached to the measure-ment nozzles, to obtain accurate flow measurement.

CleaningBy fully open the damper, one get access to the duct. Donot forget to readjust the damper after cleaning.

Technical data for DIRU, DIRBU andDIRVU

DimensioningThe dimensioning graphs show the pressure drop over thedamper with flow meter, pt. They should be used to deter-mine the pressure drop and to provide information aboutsound effect levels at different settings.

Balancing

The balancing graphs show the flow as a function of themeasured pressure, pm. These graphs should be used tobalance the system.

Shut-off damper DSU


DescriptionHas a turning, circular blade. The blade is stepless adjustable090. The damper is used when you have lower demandsfor shut-off capacity. The damper admits an insulation thick-ness of approx. 50 mm.

The damper can on occations be used for regulation.

Setting angle = 0 = open blade, = 90 = closed blade

There is a separate assembly, measuring, balancing andmaintenance instruction for this product.

631000 fullfills pressure class A in closed position.

The cup at 80630 can be complemented with the specialinsulation cup IK at insulation thicker than 50 mm.

Shut-off damper DTU


Technical data

Pressure drop graphs with noise data for

dimensioningThe solid curves show the pressure drop, pt, over thedamper as a function of flow q, and setting angle .

The dashed curves give the A-weighted sound power data,LWA, in dB to the duct.

Example

Given Dimension 100Flow 60 l/sPressure drop 200 Pa

Obtained from graphSetting angle 32Sound power level 63 dB (A)
