HTF series fire temperature exhaust fan that I Shandong Aetna Ventilation Equipment Co. developed, high temperature performance, high efficiency, small footprint than the centrifugal fan, convenient installation. Senior civil construction is now more than twenty provinces of competing choose. Features high-temperature performance: Fan tested in accordance with test standards GBJ45-82 Fire Code requirements, establish higher standards of corporate internal control assurance system, able to run more than 100 minutes at 400 ℃ high temperature conditions, running 20 hours at 100 ℃ / not damaged, are widely used in high-level civil, oven, underground library, tunnels and other occasions; wide scope of application: according to the different requirements of senior civil construction, the use of variable-speed or multi-speed drive form, in order to achieve a machine with two (ie, The purpose of commonly used through ventilation and fire temperature exhaust); and high efficiency: The fan is by the multi-objective optimization design and development of new product development, with a flat efficiency curve characteristics are conducive to energy conservation; easy installation, covering than the centrifugal less fan: The fan basic types of axial fans, tube connections and direct wall mounting and wind (installation forms can be vertical or horizontal). Largely saving footprint.
