FAQ

Q1: What is the core difference between a stainless steel high-temperature fan and an ordinary fan?

A: The two differ fundamentally in terms of material, temperature resistance, structure, and motor. The stainless steel high-temperature fan body is made of heat-resistant stainless steel such as 304/316L/310S, and can operate stably for extended periods at temperatures ranging from 100-600℃. It is equipped with a thermal expansion compensation structure, a heat insulation and cooling system, and an H-class high-temperature dedicated motor. Ordinary fans, on the other hand, are mainly made of ordinary carbon steel or galvanized sheet, and are only suitable for normal temperature ventilation environments ≤50℃, lacking specialized high-temperature protection design. Furthermore, stainless steel possesses excellent corrosion resistance, resisting the erosion of corrosive gases containing sulfur and chlorine.

Q2: How to select the appropriate stainless steel material based on the operating temperature?

Q3: What are the common faults of stainless steel high-temperature fans? How to solve them?

A: Common faults and solutions are as follows:

① Severe bearing housing vibration – Possible causes include misalignment of the fan shaft and motor shaft, friction between the casing or air inlet and the impeller, insufficient foundation rigidity, impeller deformation, or loose rivets. Solutions: Realign concentricity, adjust impeller clearance, reinforce the foundation base, repair or replace the impeller.

② Bearing overheating or oil leakage – Possible causes include charring of the bearing housing seals (above 350℃), insufficient or deteriorated lubricating oil. Solutions: Replace with high-temperature resistant graphite or metal bellows seals, and regularly check and replenish high-temperature grease.

③ Motor overheating or burnout – Possible causes include insufficient motor power, cooling system failure, or insufficient insulation class. Solutions: Under high-temperature conditions, use an H-class insulated motor and ensure the water-cooling or air-cooling system is functioning properly.

④ Insufficient airflow or reduced efficiency – Possible causes include blocked air inlet, fan reversal, and abnormal voltage. Solution: Regularly clean the air inlet and duct dust, and check the power supply phase sequence and voltage.
