FAQ

Q1: Is a PSA oxygen generator a medical device? What certifications are required for purchase?

A1: Yes, medical PSA generators fall into Class II medical devices in China. For purchase, ensure the product has a Medical Device Registration Certificate; the manufacturer needs a production license, and the seller requires a Class II medical device operation filing. For export, CE/FCC certifications and provincial "oxygen-related filing" are mandatory per GB 8982-2023.

 

Q2: Why does the oxygen tube have water droplets? Is this a fault?

A2: It's not a fault-this is condensation. Compressed oxygen generates heat, and water vapor condenses in the tube after passing through the humidifier. Solutions: Fill the humidifier cup between the max and min water levels; replace or dry the tube (blow it with the machine's oxygen outlet without the humidifier).
 

Q3: When the molecular sieve expires, should I replace the sieve or the whole machine?

A3: Don't rush to replace either. Expired molecular sieves often coincide with wear of other parts (e.g., compressors). Contact the after-sales team for a full inspection first-replace the sieve if other components are intact; consider a new machine if multiple parts fail.
 

Q4: What noise standard should a qualified PSA generator meet? How to reduce noise?

A4: Medical models must meet ≤60 dB(A) (YY 0732-2009), and industrial ones ≤85 dB(A) (YY/T 0298-1998). To reduce noise: Choose models with noise-reducing enclosures (patented tech available); place the machine on a shock-absorbing pad; keep it 1m away from walls.
 

Q5: The generator alarms for low oxygen concentration-what should I do first?

A5: First, check two points: ① Clean the air filter (clogging causes impure oxygen); ② Ensure the humidifier is properly installed (leaks lower pressure). If the alarm persists after these steps, stop use and contact after-sales for professional testing (core parts like compressors may be faulty).
