For more information PYHL-14A Francis fire temperature exhaust fan towards Cheng Fan Brand / model:? Towards Cheng Fan / PYHL-14A PYHL-14A Francis fire temperature exhaust fan towards Cheng Fan Performance Overview PYHL-??? 14A Francis fire temperature exhaust fan is a fan HTF fire temperature derivative products, the fan inlet side is equipped with manifold mufflers, which will help reduce the noise, and the product can operate normally at about 300 ℃ ambient temperature for 1 hour, This product can be used for dual exhaust ventilation, but also for ventilation, and to play a dual role in high-temperature exhaust and so on. Applies to tunnel underground garages, underground shopping malls, underground storage, advanced construction and other high-temperature exhaust, fire is the ideal accessory products, by design institutes and user choice. In case of fire, it can quickly exhaust fumes, to ensure safe access to personnel, is essential fire safety facilities. Fan impeller distorted meridional acceleration characteristic cone-shaped blade welded to the hub, using the inlet flow line trumpet muffler and duct connected into a whole, built with guide vanes, with good air distribution, pressure is stable, is mediated A new fan between axial and centrifugal fan, novel design, compact structure, small size, light weight, have high pressure centrifugal fans, axial fan of big flow, high efficiency, low energy efficiency, noise , convenient installation. ?
