The SFG Series High-Temperature Axial Fan is upgraded from the SF model with a redesigned impeller and adopts an aluminum alloy casing to enhance the motor’s sealing performance,The motor incorporates high-temperature enameled wire, high-temperature bearings, and high-temperature lead wires. Consequently, this product can operate in environments with elevated temperatures (ambient temperature ≤100°C) or high humidity. The fan features a novel structure, aesthetically pleasing appearance, and superior performance, characterized by low noise, high airflow, elevated static pressure, and smooth operation.
This product is widely used in kitchen fume exhaust, bath centers, grain drying, fruit and vegetable dryers, medicinal herb baking, Chinese prickly ash baking, pharmaceuticals, tobacco, metallurgy, power stations, transportation, grain storage, warehousing and other ventilation systems for industrial and mining enterprises as well as civil buildings.
