Air leakage testing machineProduct Introduction:
The air leakage detector is a specialized equipment for testing the air leakage in ventilation and air conditioning systems,Suitable for testing the tightness quality of air ducts, air conditioning units, fire dampers, regulating valves, etc. in hotels, restaurants, and public works, ventilation and air conditioning systems. It is an air leakage tester for construction and installation companies. The air leakage testing instrument referenced by this product,After several years of successful development, it has reached a level of application technology, with reasonable design, small size, convenient use, and designed for China's testing requirements. Its price is cheaper than imported instruments of the same performance. Its promotion and application provide an effective means of testing the sealing quality of ventilation and air conditioning duct systems, improve the installation quality of air conditioning by installation companies, and make outstanding contributions to energy conservation. Many construction companies, architectural research institutes, and university laboratories have already chosen this equipment. The air leakage detector mainly consists of a multi touch operation testing system, a high-speed fan, a variable frequency speed regulation system, a flow tube, a pressure measuring tube, a differential pressure sensor, a wind speed sensor, and other parts. execution standardGB50243-2016Code for Acceptance of Engineering Construction Quality
