Product Introduction

• The GF4-72 A-type fiberglass centrifugal fan is a high-efficiency, high-performance, low-energy and environmentally friendly fan designed and improved by our company based on the original 4-72 fan. This model's appearance is more suitable for gas flow performance. The GF4-72 fiberglass centrifugal fan is designed and improved based on the performance parameters of the metal 4-72 fan, and is made of fiberglass composite material. This series of fans can transport corrosive gases containing acidic, alkaline, and chemical components. The transported gas is not allowed to contain viscous substances, dust and hard particles ≤ 150mg/m3, gas temperature ≤ 60 ℃, and relative humidity ≤ 100%. This series of fans has the characteristics of high strength, light weight, resistance to aging, good corrosion resistance, low noise, and smooth operation. It is a high-efficiency, high-performance, low-energy universal anti-corrosion fan. This series of fans is widely used in places containing corrosive gases such as chemical, electroplating, oxidation, power plants, laboratories, circuit boards, and environmental protection equipment.

  The GBF4-72 fiberglass explosion-proof centrifugal fan is made by configuring EXdl or EXdll class A \ \ B explosion-proof isolation motors according to the customer's usage conditions. It can transport flammable and explosive volatile gases containing methane, ethane, propane, styrene, toluene, xylene, carbon monoxide, acetic acid, kerosene, gasoline, furan, etc. Its performance parameters and installation dimensions are consistent with the GF4-72 fiberglass centrifugal fan.
