The Q90 air leakage tester is a special equipment for testing the air tightness of ventilation and air conditioning and fire damper. It is suitable for large shopping malls, office buildings, automobile air leakage, subway stations and public works ventilation and air conditioning systems in the air duct, air conditioning unit, fire damper, and airtight Air leakage, control valve and other tightness quality tests...

This product uses the testing principle of the venturi nozzle method, using the internationally advanced ultra-micro hole nozzle method, and has been successfully developed over a few years on the basis of the air duct leakage tester. It is the first product air leakage tester in China. , It has reached the international advanced level in the application technology, the design is very reasonable, the size is small and easy to use, and it is designed completely in accordance with the test requirements of China, which supplements the gap in the domestic air leakage test.

The latest model Q90 air leakage tester can test the air leakage of various specifications of fire dampers, air ducts, central air conditioners, airtight rooms, etc. under complex industrial and mining and harsh on-site environments. It has variable frequency technology and high-pressure super large air volume fans. With world-class technology, the products are exported to the United States, India, Africa, Germany and other countries. The total sales volume has exceeded 1,000 units, occupying more than 90% of the domestic air leakage detection market. Compared with the air leakage that foreign manufacturers have recently developed As far as the air volume tester is concerned, first, the core components of the air leakage tester produced by our factory are all produced by Russian military industry manufacturers. It has a small air volume and a very high air pressure. The air outlet diameter is 105 mm and the maximum air volume is It is 4000m³/h, the maximum wind pressure can reach 7500Pa, and the total volume of the instrument is 30 kg, which cannot be achieved by imported instruments. Generally, the core components of imported instruments are civilian products, which results in large volume and heavy weight, and small air output. The wind pressure is not enough. The lighter the weight and the smaller the size at the test site, the more convenient it is to carry, and the instrument has portability and practicality on site. Secondly, the air leakage tester produced by our factory has the world-class frequency conversion technology, which can be suitable for all kinds of air ducts, fire dampers of various specifications, central air conditioners, and airtight rooms. Some foreign instruments do not have this function. As a result, the test air pipe was broken when testing small air pipes and low-pressure air pipes, which made it impossible to test, and high-pressure air pipes and large-area system air pipes could not be suppressed or measured. Third, the simplicity and practicability of operation. Compared with foreign air leakage testers, the instruments produced by our factory are simple to operate. Ordinary technical engineers can learn to operate and use directly by reading the instructions and schematic diagrams, which is simpler than foreign products A lot easier to understand. Fourth, market awareness. Since the products produced by our factory have been sold at home and abroad for nearly 7 years, the maturity and awareness of the products are understandable. Fifth, our company has distributors in various provinces and cities for the after-sales of products. Some small parts of customers only need to be repaired and maintained at the local distributors, which saves the trouble of the maintenance time and the manufacturers. It takes at least a few months or even more than a year to repair foreign instruments. Fifth, the price, regardless of the price of the instrument and the price of accessories, foreign products are several times or even ten times higher than ours, and foreign products are new market-oriented instrument structures and technologies that have reached maturity, and the repair rate is better than ours. Factory products are much higher. Sixth, our company promises that the small parts of the instrument will be maintained free of charge for life, which is unattainable by all foreign manufacturers. Seventh, the core motor is produced by Russia's Michele military enterprise. The motor warranty is 2 years, which is unattainable by all instruments.

Now our company's Q90 is currently the most powerful, stable, and precise finalized product on the market. It can test large-scale air-conditioning systems, air-conditioning units, fire dampers, large-scale smoke extraction systems, pharmaceutical factory purification rooms, nuclear polluted gas pipelines, airtight rooms and other multi-functional new products. The company's many years of technological innovation Q90 are exported to Europe and the United States. In developed countries, Africa, India, Pakistan and other projects under construction, the air leakage test instruments are all our company’s Q90. Q90 was the designated air leakage tester for nuclear power plants under construction in China with AP1000 system at the end of 2010. Many research institutes have updated this product after the new model Q90 obtained the national metrology license and national patent, such as Shanghai Academy of Construction Sciences, Shenzhen Academy of Construction Sciences, Guangdong Academy of Construction Sciences, China Electronic System Third Company, Shenzhen Construction Engineering Quality Inspection Co., Ltd., Shenzhen Tyco Construction Inspection Co., Ltd., Shenzhen Hengyi Construction Engineering Quality Inspection Center, Guangdong Industrial Equipment Installation Fifth Company, Guangdong Industrial Installation Fourth Company, Shenzhen Shenke Engineering Inspection Co., Ltd., Guangdong Jianyue Engineering Inspection Co., Ltd., Zhejiang Architectural Design and Research Institute, Shenzhen Jingheng Engineering Inspection Co., Ltd., China Electronic System Second Corporation, China Nuclear Industry Construction Group Co., Ltd., Dalian Weijia Shipbuilding, Dalian Shipyard, etc. have all been purchased The latest instrument of Q90.
