Cabinet centrifugal fans is to rely on the input of mechanical energy, increase the gas pressure gas delivery side mechanical wind chassis, which is a follower of fluid machinery. Centrifugal fans are widely used in factories, ventilation mines, tunnels, cooling towers, vehicles, ships and buildings, dust emission and cooling; boiler and industrial furnace ventilation and the air; air-conditioning equipment and household appliances cooling and ventilation; grain drying and should select; wind tunnel inflatable air source and hovercraft and propulsion. The unit uses quality steel production HTFC-1 exhaust air box, high strength, light weight, good looks units using high-performance, low-noise centrifugal fan, wall sound-absorbing insulation materials, with large air volume, high static pressure, noise Low and running balance clean, minimalist design makes maintenance extremely simple, demolition a few screws from the sides of the unit at either end of the unit to repair any fine within a component design, run two-speed economy exhaust wind chassis, reliable, easy to install DBF expensive wind chassis, simple type of fan aerodynamic performance test: Press GB1236 "fan aerodynamic performance test methods" in the company's air duct, plenum-type test device, with advanced testing, testing equipment for the factory fan by lot Sampling comprehensive performance test. All design and development of new products and product standards derived products must have been tested and pneumatic performance laboratory and test reports issued by performance indicators to meet the design requirements can be put into full production. HTFC-11 two-speed exhaust air box, Chen Yu-conditioned (certified), Xianyang wind chassis provided by Wu Cheng Chen-yu air-conditioning Limited. Wu Cheng Chen-yu air-conditioning Co. (www.wccykt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Chen Yu-conditioned in leadership with the staff warmly welcome all inquiries negotiations to create Chenyu air conditioning better future.
