General Description

RTC series fan has8 models according the difference of the impeller diameter: 300, 425, 500, 575, 675, 750, 900, 1000, the airflow is from 329 m/h to 57200 m%/h. The highest static pressure reaches 650Pa.

Product Features

1.Fan impeller: aluminum alloy,the impeller is processed by pressing and moulding.it is in compact structure,large airflow.low noise and high efficient.
2.Matched motor: Use the motor with IP54,and isolation class F,when the isolation class is H,the products can be contantly operated under 280C/45min,also can use the explosion proof motor,two-speed motor and frequency conversion motor.
3.Housing: It is made up of aluminum alloy, the whole fan structure intensity is designed according to the extreme outside wind speed under 50m/s,it hasa quite good wind resistance ability.
4. Funnel cap: It is made up of aluminum alloy,flat,streamline,modularized, with patent technology,in low weight, high intensity,small wind resistance,suitable for ventilation.
5. Current collector: Use the special design to make the impeller leading flow opening match with the air inlet,to effectively control the airflow,reduce the noise and improve the fan efficiency.
6.Fixing bracket: Numerical control preparing material.mouiding.punch machining of the fixing hole.it is easy for installation.
7.Gearing: This series fan uses the strap gearing,this driving method can reach the stated air rotate speed, perfectly match with the project situation. The fan bearing has been treated and tested,and its critical rotate speed is 1.3 times than the fan's highest operation speed.the strap is European type.
8.Air valve: Use the gravitational automatic turnoff or electric driving startup and turnoff. The air valve for gravitational automatic turnoff is made up of hot galvanized casing and aluminum alloy leaflet,the air valve for electric driving startup and turnoff is made up of aluminum alloy heat preservation leaflet,dew eliminating,prevent from air flow backword. Both for smoke exhaust and ventilation,can be matched with the smoke exhaust fireproof valve,the fan and the fireproof valve all have been proved by national fireproof standard.
9.Installation and maintenance: The motor shield is in button loop-type,it is easy for operation.
10.Steady operation: This series fan has the small running inertia,high acting balance precision,the balance precision reaches IS01940 G2.5 level.the whole machine has passed the mechanism,libration and pneumatic control examination,to ensure the steady and reliable operation. It also can extend the life span of the fan,reduce the noise and minish the libration.
11. The fans have passed various certifications of China compulsory product.explosion proof and AMCA.
