HTF fire high-temperature smoke axial flow fan

HTF type high temperature fire smoke exhaust summary of axial flow fan

1.1. HTF type high temperature fire smoke exhaust axial flow fan, the basic form of axial flow structure, using high temperature resistance motor, cooling system, a special motor, quality of products by the national fire-fighting equipment supervision and inspection center by GA211-1999 "fire smoke exhaust fan high temperature resistance test method" for high temperature test, under the condition of the medium temperature of 300 ℃ high temperature continuous operation more than 60 minutes, temperature of 100 ℃ continuous operation under the condition of 20 hours/time is not damaged, can be used for ventilation and smoke exhaust.

1.2. Product categories

According to the installation points: horizontal and roof type (W).

According to the air volume of subsection wind: atmospheric type have type I yao type II (double speed); Medium-pressure type (impeller inclinedflow) Ⅲ, Ⅳ type (double speed); Low voltage type D1, D2 type.

According to the speed adjustment way: single speed, double speed and frequency (adopts frequency conversion motor, with frequency conversion controller, stepless speed regulation, so as to adapt to different working condition, suggest to adjust frequency locking in 25 hz ~ 50 hz).

1.3. Noise requirements in order to adapt to different places, the fan muffler can match different length, also can be made of coated type.
