Exhaust air box classification there are many, which HTF series fire smoke the most widely used wind chassis, here you talk about three specific performance characteristics: 1.HTF series fire temperature exhaust wind chassis series of national "Spark "Project products, with excellent performance centrifugal wind chassis, high temperature performance, high efficiency, covering less than the centrifugal fan, convenient installation. 2, HTF Fire fan high temperature performance: Fan tested in accordance with GBJ45-82 Fire Code standards, establish higher standards of corporate internal control to ensure that the system can run continuously at 300 ℃ high temperature for 60 minutes or more, under 100 ℃ temperature conditions Continuous 20 hours / times without damage, widely used in high-level civil, oven, underground garages, tunnels and other places together. 3, performance HTF Fire fan performance table is listed in the most efficient wind chassis performance range, according to the air volume is divided into five performance points htf wind chassis offer, the selection according to the performance table prevail. Fire fan factory qualified under rated air flow, total pressure value error does not exceed ± 5%, the performance of the selection table is a performance standard state enterprise under the covers 25,200 square meters, the existing 40 engineering and technical personnel, including senior engineer 2, 10 mid-level engineers, strong technical force. To improve product quality low-noise wind chassis, adapt to the increasingly fierce market competition, the company since 1995, has introduced the original CNC cutting machines, bending machines, high-speed punching machine, hydraulic expanding machine and other advanced production tooling equipment, to build high-quality products and laid a solid foundation. In early 2006 the company has invested into the HVAC testing room, thus creating favorable conditions for technological innovation of new products development. The product of the performance targets are met or exceeded the international standard.
