Product Introduction

• The (Kehui brand) PP4-72 polypropylene centrifugal fan is made of polypropylene plate and welded by heating and pressing according to the performance parameters of metal 4-72. It is widely used in industries such as scientific research, chemical engineering, metallurgy, electronics, pharmaceuticals, textiles, instrumentation, electroplating, mining, schools, hotels, guesthouses, laboratories, and environmental protection equipment for ventilation and elimination of harmful gases such as acidity and alkalinity. But it is not allowed to transport corrosive gases such as halogen derivatives, ketones, etc. containing aromatic compounds, aliphatic and aromatic hydrocarbons. It has the characteristics of chemical corrosion resistance, resistance to aging, low specific gravity, low mechanical vibration, low noise, and smooth operation. The gas it transports is not allowed to contain viscous substances, dust and hard particles ≤ 150mg/m3, gas temperature ≤ 50 ℃, and relative humidity ≤ 100%. And avoid direct sunlight exposure, and there should be no heat sources near the fan site.
