Custom manufacturer of mechanical ventilation and dust removal accessories - Huizhou Spiral Duct Factory

Product Models: Manual damper, electric damper, pneumatic damper
Company Name: Foshan Ruitong Ventilation Equipment Co., Ltd.
Product Features:
(1) The connection dimensions of the opposed multi-blade air volume control valve are the same as the rectangular duct dimensions specified in the national ventilation duct standardization.
(2) The blades of the air volume control valve are of the opposed and parallel opening types, serving as control valves in ventilation, air conditioning, and air purification systems.
(3) Tests have shown that the air volume control valve has good air tightness, with a relative air leakage rate of about 5%, and excellent regulation performance.

Industrial exhaust fume system ducts, white iron ventilation ducts, and spiral ducts are thin-walled pipes made from metal strips coiled into spiral seams. They are circular, weld-free, leak-free for air and water, and are commonly used for air supply and bulk material transportation, replacing traditional white iron pipes (i.e., hand-seamed iron pipes). They are a type of fully mechanized duct, with straight pipes requiring no manual hammering.
