_HTF Exhaust fan exhaust fan exhaust fan manufacturer _HTF price _ Heng Hing air conditioning

Using a noise meter blade is lower than the existing fire fans 8-10dB low (A) power 6%. Fans main air duct medium temperature of 280 degrees and 30 minutes of continuous running series fire temperature exhaust machine 1. Uses and characteristics: 2. Uses 3. temperature exhaust machine, both for the variety of building fire smoke, but also for building , civil air defense projects, underground railways, mines and other smoke and exhaust tunnel. 2 Features: series of fire temperature exhaust fan with high efficiency, smooth operation. Low noise, high temperature, reasonable structure, and ventilation fans occupy less space two-thirds. Lighter than half. Ensure power, easy to install, can be vertical, horizontal and hanging installation. Fan design with special motor cooling system, built-in air-cooled motor type: Fan building construction according to the requirements of the use of vertical and horizontal ceiling installation. Power three-phase 380V, 50Hz fans using advanced aerodynamic set the clock above 150 degrees can be long-term continuous operation. 1. HTF series fire temperature exhaust fan state-level "Spark" product of the project, with excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation and so on. 2, HTF Fire fan high temperature performance: Fan Test conform GBJ45-82 Fire Code standards, establish higher standards of corporate internal control to ensure that the system can run continuously under high temperature 300 ℃ for 60 minutes or more, at a temperature of 100 ℃ Continuous 20 hours / time is not damaged, widely used in high buildings, oven, underground garage, tunnels and other occasions. 3, performance HTF Fire fan performance table lists the properties in the most efficient range, according to the air volume is divided into five performance points, according to prevail in the selection of the performance table. Fire fans quality products manufactured in the rated flow, total pressure error does not exceed ± 5%, the performance of the selection list is performance under standard conditions, regardless of the technical documentation or the ordering request.
