1、 Product Overview

1.1 HTF-W type axial flow fire exhaust roof fan, its basic form is axial flow roof structure, the motor adopts high temperature resistant motor, the product is tested for high temperature resistance according to GA211-2009 "Fire Exhaust Fan High Temperature Resistance Test Method", and has passed the mandatory 3C certification of the Ministry of Public Security Fire Product Qualification Assessment Center. It can operate at a medium temperature of 280 ℃. Continuous operation for more than 60 minutes under high temperature conditions, and no damage for 20 hours/time under 100 ℃ temperature conditions. It can be used for both ventilation and smoke exhaust.

1.2. Product Classification

The HTF-W fire roof smoke exhaust fan is divided into 14 specifications with a diameter of 500~1800mm, a wind volume of 6000~135000m3/h, and a total pressure of 110~300Pa. According to the speed regulation method, it can be divided into single speed, dual speed, and variable frequency (the fan motor adopts a variable frequency motor, equipped with a variable frequency controller, and implements variable frequency speed regulation to meet the needs of different working conditions. It is recommended to adjust the frequency to be locked at 25Hz~50Hz). To meet the requirements of explosion-proof environment, the fan can be made into an explosion-proof fan with an explosion-proof rating of EXdIIBT4.

1.3. The fan can be equipped with manual or electric regulating valves, self hanging louvers, etc. according to user needs.
