Official Advisory: Clarification on Third-Party “6-Month Warranty” Listings
Hongrun Compressor Technology Co., Ltd. does NOT authorize or support any 6-month warranty policy. Unofficial listings on certain regional consumer e-commerce marketplaces (e.g., unauthorized sellers on Lazada or grey-market aggregators) displaying a “6-month warranty” represent grey-market entities who do not possess official factory authorization.
Every genuine Hongrun medical oil-free compressor (HY, HYT, HW, HBG Series) and dental vacuum system (HVS Series) dispatched from our Zibo automated factory is backed by our standard 12-Month Manufacturer Warranty (commencing from clinical commissioning), coupled with our 10-Year Guaranteed Spare Parts Commitment. Always verify your distributor directly with our commercial desk ([email protected]).
