Uses: High-rise buildings, oven, tunnels, underground garage and special industrial and mining enterprises and other fire temperature exhaust, exhaust. Specifications: Fan diameter: φ350 ~ φ1500mm air volume: 3350 ~ 93800m3 / h Pressure: 280 ~ 819Pa the fan with a special compartment temperature measures, Hefei pressure blower role, built circulating impeller can be forced to cool the motor, ensure that the motor temperature is not exceeds a predetermined value. Run at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Can play a role of ventilation and fire smoke. The product was identified as Shandong Provincial Fire Department fire products sentinel production. YTPY type, fire temperature exhaust fan with high efficiency, smooth operation, low noise, high-temperature structure is reasonable, Mingguang pressure blower, easy to install, can be vertical, horizontal and hanging installation. The fan is designed with special air-cooled motor cooling system built-in motor type; the use of advanced aerodynamic design of the blade (swept forward, forward), the noise 2. Low 8-10dB (A) 6% lower power than the existing Fire fans ; main air duct medium temperature of 280 ℃ when more than 30 minutes of continuous operation, 150 ℃ when the long-term continuous operation. Product Attributes This fan uses a special compartment temperature measures built cycle impeller can forcibly cool the motor, Tongling pressure blower manufacturers to ensure that the motor temperature does not exceed a predetermined value. Run at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Ventilation and fire smoke can play a role in the product altogether divided into: ① ② atmospheric pressure single-speed two-speed single-speed ④ ③ MV MV dual-speed four series. Fire temperature exhaust fan, can be used for various building fire smoke, but also for a variety of construction, civil air defense projects, underground railways, mines, tunnels and other smoke and exhaust. Other notes The fan is designed with special high-temperature motor cooling system. Main air duct medium temperature of 280 ℃, the Huangshan pressure blower price, more than 30 minutes of continuous operation. ≤150 ℃ when long-term continuous operation. 1. Small size and lightweight light with the same amount of wind centrifugal fan less accounted for two-thirds of the space. Lighter than half. Machine by using the material classification can be divided into several, such as steel fan (general fan), FRP fan, plastic fan, fan aluminum, stainless steel, etc. 2. Fan Fan classified according to the direction of gas flow can be divided into centrifugal, axial flow, mixed flow (Francis) and cross-flow and other types. 3. The fan according to the flow direction of the airflow into the impeller into: axial fans, centrifugal fans and mixed flow (Francis) fan. 4. fan use is divided into the push-local fan (hereinafter referred to as the push-fan) and flameproof motors placed runner outside or in the flow path, explosion-proof electric motor placed in the sealed chamber withdrawable local fan (hereinafter referred to as the extraction fan). 5. A fan in the form of a pressurized can be divided into single-stage, two-stage or multi-stage pressure fan. Such as 4-72 is a single stage pressure blower is a multi-stage pressure fan 6. Fan divided according to purpose can be divided into: axial fan, Francis fan, blower, roof fans, air-conditioning fan and so on. 7. Press the fan pressure can be divided into low fan pressure fan, high pressure air.
