Factory outlets without power fan

No power ventilation advantage of excellent ventilation, zero-cost operation: DL-type non-powered ventilation without power as natural ventilation equipment, no personnel to operate 24 hours without power resources, can make the work environment dirty after installation, moist, hot air from the steady stream of fresh air into the supplement, to create a good working environment. Winter indoor condensation can be prevented, thereby protecting the roof wall fire-resistant coating to peel off from moisture. Excellent material: DL-type non-powered ventilation fuselage made of high quality stainless steel material, even in harsh environments also affected. Special manufacturing fully enclosed bearings, fully enclosed in a special sleeve to ensure sustained and stable turbine operation under normal operating conditions, without the need for maintenance. Unique support structure to ensure ventilation can withstand gale attacks. Broad applicability, safe and reliable: No power roof ventilation uses a unique variable angle diameter, as long as the 0 ~ 22.5 ° inclination of various industrial plants pressure plate light steel roof, concrete roof can be installed. And do not need support, easy to install, will not water leakage. Civil aspects: the flue outlet for the residents of the community to solve the air from time to time due to high winds and low atmospheric pressure caused by intrusion, avoid home full of fumes and odors
