Exhaust fan, with a special compartment temperature exhaust fan maintenance measures, the impeller can be built on the motor cycle exhaust fan forced cooling principle, ensure that the motor temperature does not exceed a predetermined value. It can run more than 100 minutes exhaust fan at 400 ℃, 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. Exhaust fan high temperature performance, high efficiency, small size, easy to install exhaust fan fire, etc., can be used as temperature, humidity, corrosion-resistant type roof fans, used in electric power, petroleum, chemical, metallurgy and other high-temperature, roof exhaust humidity industrial applications, ventilation. In modern industry, the most used are exhaust fan, exhaust fan So what role has it? 1, the exhaust fan shutters realized by the automatic control system fan. Louvers automatically open and close to waterproof, dustproof, beautiful effect. 2, low exhaust fan noise, air volume, low power consumption, cooling effect is obvious exhaust wind chassis, exhaust fan, liter by liter Rui Rui Electrical and Mechanical Ventilation and Air Conditioning Electrical Equipment Factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) strong, credible, Shandong Texas fan, ventilation equipment industry has accumulated a large number of loyal customers.
