■ Overpressure dampers
Overpressure dampers are used to equalize the pressures between adjacent rooms and for automatic interruption of air supply or air exhaust. Steel (Types JNŽ) or aluminium (Types ANŽ) overpressure dampers can be produced.
■ Volume control dampers
Volume control dampers regulate the air flow volume in ventilating ducts and air conditioning devices. We produce several construction types with manual, motor or pneumatic regulation.
■ Throttling, shut off and non return dampers, flow rate controllers
They are used to control the air flow volu-me in ventilating ducts.

■ Overpressure dampers JNŽ-6, ANŽ-3, ANŽ-4
ApplicationOverpressure dampers are used in all kinds of low pressure air conditioning, air heating ind ventilation, where it is necesary to equalise the pressure between adjacent rooms. They can be applied where the automatic break of the supply and exhaust air is required after conditioning-, heating- or ventilation device has been turned off.
DescriptionOverpressure dampers consist of supporting frame made of galvanized sheet steel (steel overpressure dampers JNŽ-6) or aluminium section anodised in natural aluminium colour (aluminium overpressure dampers ANŽ-3 and ANŽ-4) and horizontal swinging vanes of sheet aluminium. The horizontal vanes are inserted into plastic bearings, temperature resistant to 80 °C. Sealing stripe, attached on lower part of vanes reduces noise.
CautionIn the cases of effective velocities exceeding the values provided in the diagram of the determination of the total pressure drop on page 14, or in the cases of a likely exposure of the louvres to strong wind gusts, we recommend the installation of a constraint crossbar.
Sizes:All combinations of B1 and H1 according to the table of dimensions are possible. Non-standard dimensions are available on request.

■ Louvre for maintaining the preset pressure difference JNŽ-6W
ApplicationThe JNŽ-6W louvre for maintaining the preset pressure difference is designed for maintaining the preset pressure difference between two rooms or between indoors and outdoors. Depending on its orientation, the louvre can support overpressure or underpressure. It is a rapid-response precisely adjustable passive element for maintaining the pressure difference and is not airtight. Standard dimensions: from 200x100 to 1000x1000 with 50 mm steps. Other dimensions available upon request.
It can be used as• an underpressure louvre – to prevent the egress of
substances (chemicals, smoke, etc.);• an overpressure louvre for rooms where preventing the
ingress of polluted air is desired;• an overpressure valve – to prevent the ingress of gases
into smokeless areas.
Description• The blades are interconnected using connecting rods. • Precise adjustments are performed on-site.• Easy to set up: weights are placed on the threaded rods
and secured against unscrewing using nuts.

Air flow control unitsVolume control dampers
1. Frame of extruded aluminium sections.
2. Bar of aluminium sections (installed by B>1200 mm).
3. Blade made of extruded aluminium sections.
4. Plastic gear wheel.5. Handle for manual control and
locking made of aluminium alloy.6. Rubber sealant.
■ Volume control damper RŽ-7
ApplicationVolume control dampers are designed for regulation of air flow and pressure in ventilating ducts and air handling units.
DescriptionFrame and blades are made of extruded aluminium sections. Blades are inserted in plastic bearings. They are driven via the plastic gear wheels, fixed in the frame section with plastic holders. Mechanism is encased in separate housing and therefore protected from dust ant other influences. A rubber strip attached on blades provides better sealing. Blades open in opposed direction only. The dampers can be regulated manually (standard version) or power operated by pneumatic or electric actuator. Volume control damper is temperature resistant to 70 °C.

CombinationsIf after the end of the operation we want to prevent the invasion of external air into the system, the combination of an overpres-sure damper with steel or aluminium protection louvres can be used. The A variant is used for the outtake of air, whereas the B variant is intended for its supply. The starting point can be the dimension of the overpressure damper or the dimension of the protection louvre. It is important for the dimensions to be in the same proportion, which is evident from the draft.Louvres and dampers are available separately or combined, as desired.

■ Shut-off dampers ZL-1, ZL-2
ApplicationShut-off dampers ZL-1 and ZL-2 are used to close the air supply or air exhaust in ventilating systems which require high level of sealing and very pure air. Mainly they are used in systems fitted with abso-lute filters.During the operation, filters soil, causing the pressure drop to increase. If constant air flow through the filter is to be ensured, pressure drop must be compensated. Ab-solute filters are usually constructed with the initial pressure drop ΔpZ (on a new filter) of 140 or 250 Pa. When pressure drop reaches the double value of initial pressure drop, filter is to be replaced. To compensate the pressure difference ad-just the shut-off damper to obtain the total pressure drop on the filter and damper Δpcel which equals double initial pressure drop on absolute filter.When pressure drop on the filter increa-ses, open the shut-off damper to keep the pressure Δpcel constant (2 x ΔpZ).When replacing absolute filters, ducts must be sealed tight. Shut-off dampers are produced according to DIN 1946.
DescriptionShut-off dampers consist of housing and blade, both made of galvanised sheet steel, rubber sealant brass bearings and control mechanism. Damper can be manually controlled or by the means of electric or pneumatic actuator. In case damper is manually controlled, locking mechanism is attached.On the outer side, ZL-2 is fitted with a rubber seal.

■ Mechanical flow-rate controller MRP-1 (Circular)
DescriptionWith the circular air flow controllers with automated action, the air flow rate is controlled via an asymmetrical control flap pivoting on a smoothly running bearing, so as to provide highly sensitive response and control even with low flow rates. Manual flow rate setting is also available, by adjusting the tension of the drawing spring according to a scale denoting the desired flow rate. In selecting the controller and sizing of the ducting, the minimum air flow velocity of 2.7 m/s should be ensured.
ApplicationThese controllers are designed to control air flow rate in circular duct systems.
MaterialMechanical flow rate controllers MRP-1 are made of galvanised steel sheet. They are laser butt-welded to eliminate sharp seams both inside and outside. The joining ends are calibration pressed in conformance with DIN 24147 to provide their extreme stability and accurate fitting. Cushioned control flap: a piston damper prevents vibrations and oscillations of the control flap. On order, mechanical air flow rate controllers are also available with 25 or 50 mm acoustic or thermal insulation.
InstallationThe controller can be installed at any location of the ventilation system. Access to the ducting and the controller shall be provided in conformance with DIN 1946 T2, for the purposes of actuation and maintenance. A minimum 3xL length straight duct section shall be provided on both sides of the controller, to ensure flow stabilisation and efficient controller operation. Inlet and outlet ducting sections should be of equal diameter. The indicated refe-rence air flow velocity is approx. 4.5 m/s. Air flow velocity should be within the range of optimum flow rate. A circular rubber seal provides secure sealing, since the gap between the duct section and the joining end of the controller is thus equalised and kept constant by the weights of joining components.
Standard DesignsConstant flow air flow rate controller with tight insertion seating (joint dimension only):1. Automatic control autonomous of external energy sources,
with basic factory settings or user selected settings of referen-ce air flow rate;
2. Optional post-installation setting, by means of the setting device;
3. Maximum pressure drop across the controller 1000 Pa;4. Special controller variants available, without the setting devi-
ce, for unobtrusive installation, suitable for installation in open ducting (this design, however, does not allow flow rate setting after installation);
5. L1 = length of the insertion section, total length = L1 + 2 × L2

Air flow control unitsMechanical flow-rate controllers
■ Mechanical flow-rate controller MRP-2 (Rectangular)
DescriptionRectangular or square air flow controller is an autonomous control component that maintains, within a defined range, a specified constant air flow rate. The air flow rate is controlled via a control flap pivoting on bearings on both sides, a system of levers and a setting spring. The flap geometry ensures prompt response even under low pressure drops across the controller. The appropriate selection of the spring and the lever geometry lead to a defined correlation between the pressure drop and the position of the flap, thus maintaining a constant air flow rate.
ApplicationThese controllers are designed to control air flow rate in rec-tangular duct systems. Their application temperature range is -20 to +110 °C. The controller operation starts at the minimum response pressure drop, which is a function of the air flow rate (Diagram 2), and operates up to the maximum pressure drop of 1000 Pa, in a stable control range. Across this operation rate, the air flow rate deviations are limited to ±10 %. The controller cross section dimensions (width and height) should be selected equal to the ducting dimensions in order to avoid mechanical deficien-cies: excessive pressure drops and increased operation noises. Each flow rate controller is factory set to the flow rate requested by the customer. Within a certain range, the flow rate setting can be changed, by means of the setting device.
MaterialThe flow rate controller frame is made of galvanised steel sheet. The control flap is sated in special bearings made of PTFE for resistance against wear. To compensate any air flow oscillati-ons, the controller is fitted by a damper fixed to the control flap, serving to damp any frequencies arising during fast opening or closing of the control flap. In this way, resonance vibrations are avoided. The controller frame and connection parts conform to the sealing requirements for the angular components and class C components of the prEN 1751 standard.
InstallationThe controller can be easily installed in the ventilation system by means of its flange section. An important requirement is stable fixing of the ducting system, to prevent oscillations of the ducting in the flexible part during fast opening or closing of the control flap. Accor-ding to the general rules for the ventilation systems, DIN 1946 Part 2 (VDI rules for ventilation), access shall be provided to the system ducting, for the purposes of adjusting and maintenance.

Air flow control unitsMechanical flow-rate controllers
■ Mechanical flow-rate controller MRP-3 (Circular)
DescriptionThe circular mechanical flow-rate controller provides a constant volume flow rate in ventilation and air conditioning installations. The controllers operate without an auxiliary power supply. The air flow is regulated mechanically via a regulatory panel, which is mutually bearing and through the leverage of the spring training. The setting of the desired flow can be manual or motor driven. Circular flow rate controller may also have acoustic insulation with 45 mm of mineral wool enclosed with galvanised sheet steel.
ApplicationThese controllers are designed to control air flow rate in circu-lar duct systems. Their application temperature range is -20 to 70 °C. The volume flow rate shall be maintained constant, with a deviation between ± 5 % and ± 10 % at variable pressures between 50 and 1000 Pa. External measurements of the control-ler must suit the measured channel, so as to avoid mechanical failures: pressure loss and a higher level of noise.
MaterialMechanical flow rate controllers are made of galvanised steel sheet. They are laser butt-welded to eliminate sharp seams both inside and outside. The housing of regulator and connecting pie-ces comply with the leak tightness classification B in accordance with EN 1751.
InstallationThe controller can be installed at any location of the ventilation system. Access to the ducting and the controller shall be provided in conformance with DIN 1946 T2, for the purposes of actuation and maintenance. A minimum 3xΦd length straight duct section shall be provided on both sides of the controller, to ensure flow stabilisation and efficient controller operation.

Air flow control unitsMechanical flow-rate controllers
■ Mechanical flow-rate controller MRP-4 (Square)
DescriptionThe rectangular mechanical flow rate controller provides a con-stant volume flow rate in ventilation and air conditioning installa-tions. The controllers operate without an auxiliary power supply. The air flow is regulated mechanically via a regulatory panel, which is mutually bearing and through the leverage of the spring training. The setting of the desired flow can be manual or motor driven. Rectangular flow rate controller may also have acoustic insulation with 40 mm of mineral wool enclosed with galvanised sheet steel.
ApplicationThese controllers are designed to control air flow rate in circular duct systems.Their application temperature range is -20 to 70 °C. The volume flow rate shall be maintained constant, with a de-viation between ± 5 % and ± 10 % at variable pressures between 50 and 1000 Pa. External measurements of the controller must suit the measured channel, so as to avoid mechanical failures: pressure loss and a higher level of noise.
MaterialMechanical flow rate controllers is made of galvanised steel she-et. The housing of regulator and connecting parts comply with the leak tightness classification B in accordance with EN 1751.
InstallationThe controller can be easily installed in the ventilation system by means of its flange section. An important requirement is stable fixing of the ducting system, to prevent oscillations of the ducting in the flexible part during fast opening or closing of the control flap.
