HTFC fire smoke tank centrifugal fan points A and B two structures, the electric motor mounted on the outside of the box for the type A, the high temperature test, at the flue gas temperature higher than 280 ℃ high temperature, 40 minutes of continuous operation above, to achieve the purpose of fire smoke, equipped with two-speed motor after pipeline centrifugal fans, both at low speed ventilation, but also at high fire smoke, for a machine with two; motor is mounted in the housing for B-type two-speed centrifugal fan prices, generally for use piped exhaust ventilation. HTFC Fire (ventilation dual) low noise cabinet centrifugal wind chassis products are widely used in hotels, hotel schools, auditoriums, theaters, senior residential and industrial and other needs of fire smoke and ventilation options, it also can be used for supporting the central air conditioning system, cleaning system. HTFC series of fire (ventilation dual) low noise cabinet centrifugal wind chassis products in one machine to reduce the space occupied two-speed centrifugal fan, saving a lot of investment centrifugal fan, Fan extensive use of the product selection, and low noise, can replace part of the low-pressure and high-pressure centrifugal fan axial fans use. Features: 1, choose the former multi-leaf dome low noise centrifugal impeller, high-quality bearings, shaft, and a variety of materials (color-coated, galvanized sheet) made silencer structure; 2, fan with belt drive mode, with different speeds parameter adaptation requirements, special specifications can be designed, manufactured; 3, A-type external motor - with exhaust fan fire. Built motor type B - ventilation, with two-speed motor for type II - transform mining use; 4, A-series wind chassis, at a temperature of about 280 degrees 30min to reach normal operating environment for the purpose of fire smoke.
