Function

The airflow rate is adjusted by turning the adjustment

knob in order to change the aperture size of the

adjustment cone formed by iris blades. Once the

opening area is reduced, the airflow rate decreases

and the total pressure loss caused by the device

increases.

The airflow can be determined by measuring the

differential pressure in the measurement taps.

PRA 100315

The operating mechanism is positioned partly outside

the device and between the adjustment cone and

casing. The unit can be cleaned with normal duct

sweeping equipment when the device is fully opened.

PRA 4001000The operating mechanism is located partly outside the

device and inside the adjustment cone. The device can

be cleaned with normal duct sweeping equipment,

when the device is fully opened and the cleaning

equipment is passed carefully through the operating

mechanism.

Supply air jet nozzle PRA/S

The PRA-unit can also be used as a supply air nozzle

in e.g. industrial spaces. Refer to the technical data for

PRA/S -model presented in the technical performance

chapter.

Installation

Fix the damper to the ductwork e.g. with rivets.

Ensure that the rivet does not prevent the operation of

the PRA. The position of the rivet must be at least 10

mm from the duct end.

The PRA iris damper shall be installed in the ductwork

taking into account the safety distances outlined in

the installation guidelines. Safety distances are not

required next to duct transitions between only one

nominal duct size.

The orientation of the unit shall correspond to the

airflow direction. The airflow direction is marked with

an arrow indicator on the label on the casing. In order

to get accurate measurement readings the orientation

of the unit shall be selected so that the location of the

measurement taps (below the knob) corresponds tothe installation guidelines.

Safety distances

Recommended safety distance in order to get

accurate measurement readings are presented in the

figure below.

Direct duct with no flow disturbances

- safety distance 4 D upflow of the PRA unit

- safety distance 1 D downflow of the PRA unit

In cases where recommended safety distances cannot

be met, use the correction factors of the attached

figures for determination of the airflow rate.

Note the position of the measurement taps marked in

the figures.

Adjustment

Set the adjustment knob in the desired adjustment

position (pre-set position if available).

The airflow rate is determined by measuring the

differential pressure in measurement tabs using a

manometer.

The flow rate is calculated using the formula below.

K-factor is retrieved in both the tables presented

below and in installation guidelines. K-factor depends

on the unit size and adjustment position (a).

Note that when recommended safety distances are

not met, the correction factors for the installation case

shall be used.

Function

Constant airflow damper RMC is an independent

control element operating without an external power

supply, maintaining the required airflow rate regardless

of upstream pressure changes. Consequently, system

balancing is not needed.

As the dynamic pressure in the duct branch increases,

the damper turns, thus increasing the pressure loss

and preventing an excessive increase in the airflow

rate. Similarly, as the dynamic pressure increases, the

spring returns the blade to the open position, reducing

the pressure loss and thus maintaining a constant

airflow rate.

The constant airflow damper includes a damper

blade, supported by bearings and connected to

an adjustment spring. As a result of the balance

between aerodynamic forces and the spring effect,

the necessary throttling effect is achieved and the set

airflow rate is achieved.

Operation range

The constant airflow damper operates from a

minimum pressure difference over the unit, which

depends on the air velocity (see diagram below) to a

maximum pressure difference of 1000 Pa.

For example, if air velocity in duct is 7 m/s, the unit

pressure loss is approximately 100 Pa or above.

Installation

Safety distances for the damper

The airflow control damper should be installed in

undisturbed airflow. The airflow velocity profile in the

duct should be sufficiently even, without disturbances

caused by bends, T-branches etc.

The necessary safety distance after a bend or a T-

branch is 3 x the duct diameter.

The airflow control damper should be installed so that

the arrow on the damper corresponds to the direction

of the airflow. See the installation examples.


The constant airflow damper shall operate without an

electric or pneumatic external power supply.

The damper casing shall be made of galvanised steel

and the blade of aluminium.

The damper shall operate with an adjustable spring.

Dampers shall be factory-set to the required airflow

rate.

The damper with a manual adjustment device shall be

able to be easily set or reset on the work site, during

commissioning.

The damper casing shall be insulated with mineral

wool as sound and heat insulation material (optional).
