Introduction
Analysis of standard technical framework
| Core indicators | Standard requirements | Test methods |
|---|---|---|
| Air supply volume | ≥8L/min | GB 30864-2014 6.4.3 |
| Continuous use time | ≥480 minutes | Mechanical lung simulation test |
| Respiration tracking response time | ≤1 second | Actual test of 5 test subjects |
Filter element classification system
Take the KN95 filter element as an example. Its sodium chloride particle filtration efficiency must be ≥95%, which is suitable for medical and epidemic prevention scenarios; while the KP100 element has a filtration efficiency of 99.97% for oily particles, which is more suitable for use in the chemical industry.
Implementation recommendations
- Medical institutions should give priority to products marked with bacterial filtration efficiency (BFE) ≥ 95%
- Explosion-proof sites need to verify GB 3836.1 intrinsic safety certification
- Regularly test the breathing follow-up response time, and it is recommended to verify it with the stopwatch method every quarter
Technology evolution analysis
Compared with traditional PAPR, this standard introduces breathing synchronization control technology for the first time, which increases the motor response delay from 2-3 seconds to within 1 second and reduces energy consumption by 40%. The 2020 version adds synthetic blood penetration test requirements to promote the application of products in emergency departments and other scenarios.
