Import Air Respirator — Buy in Bulk from Supplier in China

The RHZK series self-contained open circuit compressed air breathing apparatus from China Hangyu Industry Co., Ltd. is a respiratory protection device designed for hazardous environments where ambient air is unsafe to breathe. It operates as a positive-pressure, open-circuit system, drawing breathable compressed air from a cylinder carried on the user's back rather than filtering surrounding atmosphere. The unit is intended for fire-fighting, chemical processing, emergency response, and industrial maintenance where oxygen deficiency, toxic gases, or particulate contamination present immediate danger to life and health.

The apparatus typically comprises a carbon composite or steel/aluminium alloy cylinder, a pressure reducer with demand valve, a full-face mask with speech diaphragm, and a harness assembly with quick-release buckles. Cylinder capacities for this class of equipment commonly range from 4.7 to 9.0 litres water equivalent, providing 30 to 60 minutes of working duration at standard consumption rates of 30 litres per minute. The harness and backplate are usually constructed from flame-retardant, anti-static polymer materials with padded shoulder and waist straps for extended wear. Face masks feature a five-point head harness, anti-fog interior, and wide polycarbonate visor with neoprene or silicone sealing edge to accommodate varied facial profiles and facial hair considerations.

Primary buyers include municipal fire services, petrochemical plant safety departments, hazardous materials response teams, and industrial facilities governed by respiratory protection programmes under OSHA 1910.134 or equivalent national standards. The unit requires regular inspection, cylinder hydrostatic testing every five years, and annual flow and pressure testing to maintain operational readiness. Buyers should confirm cylinder material and capacity, mask compatibility with other personal protective equipment, and whether the supplier provides training protocols or after-sales technical support. Shipping terms and lead times should be discussed directly with China Hangyu Industry Co., Ltd. given the response rate currently sits at zero percent.

China Hangyu Industry Co., Ltd. is located at City Town 9-10, Nanan District, Chongqing 400060, China, placing it in a major industrial municipality in southwestern China with established manufacturing infrastructure for safety equipment. The supplier holds a trust tier classification of 'harbor' and an 'imported' supplier tier, which indicates a particular verification or onboarding pathway rather than a domestic Chinese marketplace participant. The response rate is recorded at 0.00 percent with an average response time of zero hours, strongly suggesting this is either a new listing, a dormant account, or a profile where engagement metrics have not yet populated in the system.

The listing does not disclose manufacturing certifications, factory audit results, years in operation, headcount, annual revenue, specific clientele, or export history. No information is provided about in-house research and development capabilities, quality management system registrations such as ISO 9001, or proprietary technology. Buyers should treat the claimed ISO and CE compliance on the product itself as requiring independent verification through certificate copies with traceable accreditation body marks. Direct communication with the supplier is essential to establish current production capacity, whether they manufacture SCBAs directly or operate as a trading company, and what technical documentation accompanies each shipment.
