Fixed and overpressure louvres are used for covering different gaps in air-conditioning and ventilation systems. They are made of galvanised sheet steel and aluminium profiles. Multi-leaf dampers are used for air volume and pressure control. Sand-trap louvres are used for separation of sand from air stream. Combined louvres are combinations of a fixed louvres and pressure relief dampers or fixed louvres and multi-leaf dampers. They are used in zones with big wind velocity, whan it is neccessary to install fixed louvres, in front of multi-leaf dampers or pressure relief dampers.

Reinforced multi-leaf dampers are intended for application in hard working enviroment with regard to temperature. Casing and blades are made of thick, additionally reinforced, galvanized sheet steel. Stainless steel version is also available at request.

Air volume control dampers serves for manual regulation/control of airflow in ventilation. It is made of galvanised sheet steel. Smaller sizes have plastic control mechanism and bigger sizes have metal control mechanism.

Air-tight dampers are used to shut off volume flows in ducts of ventilation and air-conditioning systems. It is tested to DIN 1946 (part 4). Damper can be operated manually or actuated by an electric motor. It consists of casing, damper blade and attached mechanism. The majority of damper parts are made of galvanised sheet steel, while the bearings are made of brass.

Round backdraught dampers are used for independent closing of ventilation ducts in ventilation systems after the fan is turned off. It also prevents unwanted air flow (warm air flowing out or cold air flowing in). Casings are made of galvanised sheet steel and blades are made of thin aluminium sheet. They are designed, so that blades and the spring system prevent a considerable drop in pressure.

Rectangular Air Volume Control Damper RVP-P
Air volume control dampers enable regulation of supply or exhaust air volume in ventilation systems. Depending on project requirements it can be controlled over temperature, quality, occupancy or some other sensor. Data about measured differential pressure is transfered to the motor mechanism where it is beeing compared with reference signal. Depending on the difference, mechanism is opening or closing the damper and assures the optimal air volume in the room.

Control dampers are installed in supply and exhaust air ducts and ventilation systems with purpose of keeping constant air volume regardless of pressure changes. They do not use any additional power source for functioning. Constant air volume is enabled through a balance between the aerodynamic force and force of closing mechanism spring unaffected by air pressure changes inside the system.
