T ECHNICAL D ATA S HEET CPF Compressed-air Breathing-air Filters Model CPF-20 for up to two operators: Stock No. 03578 Model CPF-80 for up to four operators: Stock No. 03527 Note: For safe, efficient blasting, read and follow the owner's manual and seek training for everyone who will use this equipment. Purpose The CPF filter removes mists, including oil mists, water vapor, and particulates greater in size than 0.5 micron. NOTE: CPF filters do not remove CO or convert CO to CO2, or remove other toxic gases. Requirements for Operation Compressed Grade D quality breathing air as defined by the Compressed Gas Association commodity specification: G-7.1 (www.cganet.com). Description of Operation The CPF filter is placed in the breathing-air line between the breathingair source and the respirator supply hose. The CPF is the point of attachment for the respirator hose. Air enters the filter through one of the inlet ports. Moisture is removed by expansion in the outer chamber and is drained through a petcock at the bottom of the unit. The air passes through a replaceable filter cartridge. The outlet pressure is controlled by a regulator on the cap and is measured by a gauge downstream from the cartridge. Advantages • One filter serves multiple respirators CPF-20 is easily converted to CPF-80 to service additional respirators • Polypropelene filter cartridge casing eliminates corrosion hazard • Filter cartridge lasts up to 3 months. • Filters can be floor or wall mounted. CPF-80 CPF-20 Pressure Regulator and Gauge Clean Air to Respirator Pressure Relief Valve Approvals and Certifications CPF filters comply with OSHA regulation 1910.94 (6) as a component of a total respirator system. To comply with OSHA regulation 1910.134 (d), the system must also include a NIOSH-approved supplied-air respirator and carbon monoxide (CO) monitoring and/or removal system.
