VC 4-75 (VR 88-72.1-5.5, VR 80-75-5) medium pressure centrifugal corrosion-resistant fans, made of AISI 403 stainless steel for aggressive environments.
This fan is designed for ventilation or air conditioning systems for air and other gas mixtures contaminated with aggressive gases and vapors, where the resistance of stainless steel is higher than that of ordinary quality steel, not containing fibrous materials, sticky substances, dust, and other solid impurities in amounts not exceeding 100 mg/m3, under moderate (U) climate conditions (placement category 3) and tropical (T) climate (placement category 2).
The impeller consists of a front and rear disk, 12 sheet blades, and a hub.
