Note that the rated outlet flow is about 80% of the inlet flow (for example, BHD-100 accepts 100 SCFM inlet and supplies 80 SCFM outlet), because a portion of air is used for desiccant regeneration. Match your peak respirator demand to the model's outlet flow, confirm the inlet connection size, and verify your supply pressure falls within 60 to 175 psig.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDelivers OSHA Grade D and CSA Z180.1-13 compliant breathing air.\u003c\/li\u003e\n\u003cli\u003eReduces CO and CO2 to safe levels using a low-temperature oxidation catalyst.\u003c\/li\u003e\n\u003cli\u003eHigh-quality CO monitor included as standard for constant outlet sensing.\u003c\/li\u003e\n\u003cli\u003eAll-in-one package with mounted coalescing prefilter, activated carbon after-filter and particulate final filter, no separate third vessel required.\u003c\/li\u003e\n\u003cli\u003eNEMA 4 programmable controller with ethernet communication for remote monitoring.\u003c\/li\u003e\n\u003cli\u003eTwin tower desiccant design for continuous, reliable dry breathable air.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInlet flow: 50 to 1,000 SCFM at 100 psig\u003c\/li\u003e\n\u003cli\u003eOutlet (breathing air) flow: approximately 80% of inlet (40 to 800 SCFM)\u003c\/li\u003e\n\u003cli\u003eStandards: OSHA Grade D (US), CSA Z180.1-13 (Canada)\u003c\/li\u003e\n\u003cli\u003eOperating pressure range: 60 to 175 psig\u003c\/li\u003e\n\u003cli\u003eInlet air temperature: 40 to 100°F\u003c\/li\u003e\n\u003cli\u003eAmbient air temperature: 38 to 105°F\u003c\/li\u003e\n\u003cli\u003eConnections: 1\/2\" NPT up to 3\" flange depending on model\u003c\/li\u003e\n\u003cli\u003eIncluded: CO monitor, coalescing prefilter, activated carbon after-filter, particulate final filter, NEMA 4 controller\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIdeal applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSupplied-air respirator and airline breathing systems\u003c\/li\u003e\n\u003cli\u003eAbrasive blasting, painting and coating operations\u003c\/li\u003e\n\u003cli\u003eConfined-space entry and industrial maintenance\u003c\/li\u003e\n\u003cli\u003eChemical, petrochemical and pharmaceutical facilities\u003c\/li\u003e\n\u003cli\u003eAny operation requiring OSHA Grade D breathing air from compressed air\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the BHD meet OSHA breathing air requirements?\u003c\/strong\u003e\u003cbr\u003eYes.
