Are Hongrun medical air compressors certified 100% oil-free?

Yes. All Hongrun medical compressors hold ISO 8573-1 Class 0 zero-oil purity certification and China NMPA Class II medical device registration, delivering 100% oil-free air for dental chairs, clinical laboratories, and surgical suites.

How to size oil-free air compressors and suction units for dental clinics?

For 1-3 chairs, the HY-100 or HY-200 series provides 100-200 L/min at 5 bar. For 4-8 chairs, the HYT-300 or HYT-500 dual-pump redundant system with simultaneous coefficient k=0.70 is recommended. For central suction, HVS-300 to HVS-1500 systems support 1 to 50 chairs.

Does Hongrun provide OEM/ODM and custom engineering for global distributors?

Yes. With 30+ years of manufacturing experience, 160,000+ units annual capacity, and global export packaging, Hongrun offers complete OEM/ODM solutions including customized voltages (110V/220V/380V, 50Hz/60Hz), tailored decibel enclosures, and private label branding.
