Q1: What does "100% oil-free" mean?
A1: The compression cavity uses water-lubricated or dry scroll structure without lubricating oil. The exhaust air contains no oil mist or oil residues, which meets ISO 8573-1 Class 0 oil-free air standard.

 

Q2:Will strong vibration affect surrounding precision equipment?
A2: Equipped with high-density shock absorbers at the base. Vibration amplitude is tiny, and it will not interfere with precision instruments and automated production lines.

 

Q3:What are daily routine maintenance items?
A3: Regular replacement of air filter and water filter (water-lubricated type); no piston ring, valve plate and other frequent consumables replacement required. Maintenance cycle is long and operation cost is low.

 

Q4: How long is the warranty period?
A4: One-year whole-machine warranty, extended warranty for the scroll host is optional; global spare parts supply and remote technical guidance are provided.

 

Q5: Which industries are this compressor suitable for?
A5: New energy vehicle, Food & beverage, pharmaceutical, precision electronics, laboratory, medical equipment, textile, lithium battery, cosmetic production and other industries with strict air purity requirements.

 

Q6: Why does the unit overheat and alarm?
A6: ① Blocked air filter or cooling air duct; ② Excessively high ambient temperature; ③ Fan failure. Clean filter & duct, improve ventilation or replace cooling fan to solve the problem.
