Francis (oblique flow) fan, pressure coefficient higher than the axial fan blower, centrifugal fan flow coefficient than the large roof fan rain hood factory price, with the pressure and flow are "sort" of the occasion. It fills the gap between axial fans and centrifugal fans of. Along with easy installation features. Francis turbine combines axial and centrifugal fans feature shape looks more like a traditional axial fan. The cabinet may have an open inlet, but more commonly, it has a shape bent at right angles, so that the motor can be placed outside the pipe. Excretion shell slow expansion to slow down the flow of air or gas, and the kinetic energy is converted to useful static pressure. HTF series fire temperature exhaust fan system state-level "Spark" product of the project, with excellent performance FRP fan price list price, 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 damaging the FRP corrosion fan price list is widely used in high-level civil, oven, underground garages, tunnels and other occasions. 3, performance HTF Fire fan performance table is listed in the most efficient range of performance, according to the air volume is divided into five performance points, according to prevail in the selection of the performance table. 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, regardless of the technical documentation or ordering requirements.
