Product Overview:

LXHQ damper is a device used to regulate the flow of air or flue gas, which is widely used in boiler air supply, induced draft system, ventilation duct, dust removal equipment, environmental protection engineering and air conditioning system. The air door realizes the on-off or continuous adjustment of the flow through a rotating baffle or a sliding plate surface, has the characteristics of simple structure, flexible adjustment, rapid opening and closing and the like, can be controlled manually, electrically or pneumatically, and is suitable for various working conditions such as normal temperature, high temperature, corrosion, dust and the like.
