Constant mechanical air volume controllers are meant for input or output air systems. Controllers
can be installed in horizontal or vertical position with horizontal blade axis. The aerodynamic
forces acting the list due to the flow are compensated by the control device adjusted according
required flow.

Mechanical controllers need not be connected to any external power source.

Adjustment of required flow is simply performed by lever with a pointer and scale.

The controller consists of the casing of the controller with a control blade and control device.
Control device is placed inside of box with scale for adjustment of required flow. Accuracy of the
scale is ± 5 %.

Controller characteristics

● Nominal size 200x100 ÷ 600x600

● Length L = 350
● Thickness acc. to EN 1751 External casing leakage class C
● Air flow volume 250 ÷ 12 000 m /h
● Accuracy 10% -15% (on the min./max. positions 20%)

Working conditions

The faultless functioning of the controllers is ensured under the following conditions::
a) maximum speed of air flow 10 m/s
b) maximum pressure in the duct 1000 Pa
c) the air circulation in the whole controller section must be secured as steady on whole
surface

Controllers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.

Controllers are suitable for systems without abrasive, chemical and adhesive particles.

Temperature in the place of installation is permitted to range from 0°C to + 50°C.

The controller consists of the casing of the controller with a control blade and control device.
Sliding bearings of blade axis are plastic. Control device consist of spring and shock absorber.
On the top of control device box is lever with a pointer and scale for adjustment of required flow.

Controllers can be alternatively equipped by actuating mechanism. It enable remote adjustment

of required flow. In this case actuating mechanism don’t control controller damper. Actuating
mechanism control setting of lever for adjustment of required flow. If is used actuating mechanism
temperature range is from 0°C to + 50°C.

The controller body can be alternatively insulated.

* From B ≥ 400 are controllers assembled from two equal units placed in one case - side to side. Requested air
volume is sum of air volume for each controller. Controllers are equipped by two mechanical control or two
actuating mechanisms.

Controllers are intended for installation in ventilation ducts. Operating position is horizontal or
vertical with horizontal blade axis.

The controller has to be installed in the direction of air flow. Air flow direction is marked with an
arrow on the control panel device.

For faultless functioning, the air circulation in the whole controller section has to be secured as
steady on whole surface. Distance between controller and duct elements (bends, double branch
joints etc.) has to be minimal 2 x U (double branch joint) and 1 x U (bend).

The controller body should not be deformed in the course of installation.

Controller casings and control device parts are made of galvanized steel plate. Controller blade
is made of aluminium plate. Damper axis and spring are made of stainless steel. Bearings are
made of plastic.
The controller is delivered without further surface treatment.

According to the customer's requirements, damper can be made of stainless material.

Specifications for stainless-steel models – classification of stainless steel:
● Class A2 – Food-grade stainless steel (AISI 304 – ČSN 17240)
Most metal components of the damper except for the servo drive are made from said stainless
steel.
The following components, including the fasteners, are made from AISI304 stainless steel at all
times:
1) Damper body and all components permanently attached
2) Leaf axis + leaf mounting bolts inside the controller
3) Control panels (upper, lower)
4) Internal mechanical controls – holder of tensioning pin, pin safety, levers, pins
5) Control lever including fasteners
Air volume control is manufactured from sheet aluminium.
The air volume control damper has an aluminium shell.
The springs in the control mechanism are stainless steel AISI301 – EN10270-3
Plastic components, sealants, servo drives, and end switches are identical for all material variants
of the dampers.
Any other requirements for the design shall be considered atypical and shall be addressed on an
individual basis.

The appliance is constructed and preset by the manufacturer, its operation is dependent on
proper installation and adjustment.

Controllers are transported by box freight vehicles without direct weather impact, there must not
occur any sharp shocks and ambient temperature must not exceed +40°C. Controllers must be
protected against mechanic damages when transported and manipulated.

Controllers are stored in indoor environment without any aggressive vapours, gases or dust.
Indoor temperature must be in the range from -5°C to +40°C and maximum relative humidity 80%.
Controllers must be protected against mechanic damages when transported and manipulated.
