Regulation dampers
Regulating dampers are used in HVAC systems to control the air flow volume by means of adjustable rotating blades. The regulating dampers are supplied with manual control or with control by means of 24V / 230V servo-drives. The dampers can be supplied in airtight design. The regulating dampers are manufactured circular and four-sided in all dimensions up to 2000x2000 mm. As standard, we supply regulating dampers made of galvanized sheet metal or of stainless steel and aluminium.
Alternating dampers
Alternating dampers are used in HVAC systems for the division or mixing of air of individual duct routes. Thanks to their design, they divide the air from one duct into two or vice versa, from two ducts evenly into one. The circular alternating dampers consist of one extended T-piece and two interconnected regulating dampers. Possibility of other materials: stainless steel, aluminium, aluzinc. The alternating dampers are supplied with manual control or with control by means of 24V / 230V actuators. The dampers are suitable for mixing of supply air for small ventilation or heat recovery units.
