Bellows used to generate wind power equipment, consisting of a wooden box, a wooden sliding wooden handle and activities constituted. The operator manually opened activity boxes, air through the intake port so that the bellows leather sack filled with air, and does not collapse tank centrifugal fan, and pull it inside the body of the air can be pushed out of its cabinet fire htfc wind chassis, lose air through the duct, you can enter the smelting furnace and low noise cabinet centrifugal wind chassis, for iron. The most common form of the wooden, rectangular wooden boxes constitute activity for the blast so strong fire. Bellows piston driven by air pressure and automatically open and close valves, metal metalworking become effective blast equipment. Cabinet centrifugal wind chassis manufacturers, rich ventilation equipment (certified), tank centrifugal blower provided by Dezhou Plumper ventilation plant. Dezhou Plumper ventilation plant (0) is the leader in Dezhou, fans, ventilation equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
