▲1. Meets all performance requirements of the national standard XF124-2013/GA124-2013 "Positive Pressure Firefighting Air Breathing Apparatus", provide copies of test reports issued by nationally recognized testing institutions.
2. Provide valid fire product certification certificates consistent with the bid product model (certification unit) (as indicated on the certificate).
3. If the model is a sub-model, the main model inspection report must explicitly state that it covers this product; if the main model test report does not cover the sub-model, both main and sub-model test reports must be provided.
4. The pressure heads-up display uses wireless connection; the minimum operating ambient temperature of the display device is ≤-40℃, the maximum is ≥60℃; the mask can be directly cleaned and disinfected.
5. The pressure heads-up display shows remaining air status via red, yellow, and green colors based on cylinder pressure. Electrical components have explosion-proof performance ≥ExiaIICT4 and protection rating ≥ IP67. Provide explosion-proof certificates for HUD and wireless pressure sensors.
6. Back frame, harness straps, buckles, and cylinder sleeves are made of flame-retardant materials, producing no molten dripping, with afterflame time ≤3s.
7. After testing according to XF(GA) 124-2013 "Positive Pressure Firefighting Air Breathing Apparatus" standards, the mask, medium-pressure hose, and demand valve produce no molten dripping, with afterflame time ≤0 seconds.
8. Overall airtightness: After the airtightness test, the pressure gauge indication drops by ≤1MPa within 1min.
▲9. Dynamic breathing resistance: At cylinder pressure 30 MPa~2 MPa and ventilation volume 40×
2.5L/min, inhalation resistance ≤310 Pa; exhalation resistance ≤780 Pa; at cylinder pressure 2 MPa~1 MPa and ventilation volume 25×2L/min, inhalation resistance ≤330 Pa; exhalation resistance ≤600 Pa.
▲10. High-temperature resistance test: Exhalation resistance ≤710Pa; Low-temperature resistance test: Exhalation resistance ≤590Pa.
▲11. Radiant heat resistance test: After airtightness test, pressure gauge indication drops by ≤2MPa within 1min; at cylinder pressure 30 MPa~2 MPa and ventilation volume 40×2.5L/min, inhalation resistance ≤260Pa; exhalation resistance ≤720Pa. ▲12. Full-face mask has a wide field of view, using a Kevlar mesh hood; lens is anti-fog, scratch-resistant, impact-resistant, with no visual distortion; mask has window defogging function. Total field of view retention rate ≥80%, binocular field of view retention rate ≥65%, lens light transmittance ≥90%, CO2 content in inhaled air <1%.
13. Mask features long-distance communication and amplification functions; the long-distance communication device does not obstruct the wearer's line of sight or head movement. Communication is clear over a distance of 1Km in an open area without obstacles.
14. Reducer output pressure should be between 0.50MPa~0.80MPa.
15. Shoulder straps have reflective strips; cylinder fixing straps are easy to extend/retract and feature a quick-adjust locking mechanism.
16. Cylinder valve opens counter-clockwise; the valve has a non-opening pressure display function, allowing dual-side cylinder pressure indication for easy checking.
17. Carbon fiber fully wrapped aluminum liner cylinder, water capacity 6.8L, working pressure 30MPa, neck thread M18× 1.5, operating ambient temperature ≥-30～+60℃. The entire cylinder body is protected by an aramid flame-retardant fabric sleeve (color matching navy blue combat uniforms), with two rings of yellow-silver-yellow reflective markings sewn onto the sleeve.
18. Product labeling and packaging meet XF(GA)124-2013 "Positive Pressure Firefighting Air Breathing Apparatus" requirements. Each respirator's hose, demand valve, reducer, mask, back frame, and cylinder must bear the manufacturer's name and registered trademark. Prominent markings on each respirator's packing box must include: Manufacturer's name, address, and registered trademark; Product name and model; Production date and batch number; Code of the executed standard; Certification mark or approval document number.
