brand fan factory direct supply pp4-72 polypropylene centrifugal fan 品牌风机厂家直供PP4-72型聚丙烯离心通风机

Type PP4-62 polypropylene centrifugal ventilator is manufactured using polypropylene plates, heat-pressed and welded according to the performance parameters of metal 4-62. It is widely
Applied in scientific research, chemical engineering, metallurgy, electronics, medicine, textiles, instrumentation, electroplating, mining, schools, hotels, guesthouses, laboratories
Used in industries such as environmental supporting equipment for ventilation and the removal of harmful gases like acid and alkali. However, it is not allowed to transport aromatic compounds.
Halogen derivatives, ketones, and other corrosive gases such as aliphatic and aromatic hydrocarbon compounds. They are resistant to chemical corrosion and do not age easily.
Features such as low specific gravity, minimal mechanical vibration, low noise, and stable operation. The gas it transports must not contain viscous substances, and the dust it carries should also be minimal.
And hard particles ≤ 150 mg/m³, gas temperature ≤ 50°C, relative humidity ≤ 100%. Also, avoid direct sunlight, and there should be no heat sources near the fan installation.

The fan parameters are as follows:
