PDF DownloadMQ coal gas boosting fan, outputting high pressure, with reliable explosion-proof and leakproof design, is exclusively used in conveying combustible gas at normal temperature or high temperature. It is suitable for metallurgy, chemical, fertilizer and other need transporting combustible gas applications. In circumstances that could satisfy the requirement of pressure, high pressure centrifugal fan can replace cast iron shell high pressure centrifugal fan.
2. Casing adopts explosion-proof design, good safety
3. Leaking-proof design for the Casing in several locations, sealed well
4. Small volume, compact structure, can be installed in narrow space.
5. Easy for installation, no need professionals to direct.
6. With Small starting current, don’t need motor soft start device for below 7.5kw power.
7. Running test and vibration value test are done for fans after finishing manufacturing, ensuring reliable running.
