Aluminum exhaust hood

The aluminum material pumping system produced by our company has ziu for safe pumping design. Its aluminum tube is made of high-quality A00 aluminum ingot (purity 99.99%) high-temperature mold stretching and one-time molding. It is the domestic environmentally friendly aluminum alloy. The tube is thickened in thickness and the wall thickness reaches 2 mm, which meets the requirements of international standards. The surface is oxidized and looks bright and beautiful.
    The plastic part is like the joint head. It is made of shatterproof high-strength PP (polypropylene). It has good sealing performance, can be extended for continuous use, long life and strong safety. It is not affected by the use time, so it can play a large role.
