Performance parameters 1, spiral into the chassis, the exhaust port structure, reducing the pressure oscillation amplitude, reducing the impact of counter-current to the rotor, thus effectively reducing the noise. Gears using a special Cr-Mo-Ti steel after appropriate quenching treatment, strict precision lapping stage gear license JISI cut production, not only to extend the service life, and of achieving a low noise, the gear of the products from harmful interference completely ruled out. 
 2, the impeller using a special compound linear, easy to maintain uniformity of impeller clearance, reducing the internal leakage and improve the volumetric efficiency, the impeller in the manufacturing process has become a state of equilibrium, almost no vibration. 
 3, with a forced aspirated and exhaust features hard, that when the pressure changes, the flow rate has changed little, the pressure changes with changes in system resistance with adaptive sub-file flow of dense, covering a wide range of choice available to the user a wide range . 
 4, the transmission medium is not oil, clean, clean inside the case do not need oil lubrication, and avoid the use of bearings and gears inside the case of oil mixed with the structural design. 
 5, high precision, good performance, reliable, long life, simple structure, maintenance, and easy maintenance. Including attachments, fans of the main standardization, there is a perfect production system can always respond to your request. 
 6, PTR system blower blower boost in the range of 80kPa running without cooling water 

 PTR series fan uses that are widely used in electric power, petroleum, chemical, fertilizer, steel, ceramics, oxygen, cement, food, textile, paper making, tobacco, sewage treatment, pneumatic conveying, mining and other industries.
