The GENERALAIRE RF-1 is a microfiber replacement filter cartridge designed for use in oil filtration systems. This cartridge-style element fits inside compatible oil filter housings and captures contaminants from the oil supply before they reach burner components. It is a direct-fit service part installed by oil heat technicians during routine maintenance or when filter performance degrades. The microfiber construction provides effective particle capture suited to residential and light commercial oil-fired heating applications.
The RF-1 cartridge is used in oil-fired heating systems where inline oil filtration is required between the oil tank and the burner. It is a service replacement element intended for periodic replacement as part of a standard oil heat maintenance schedule. Typical installation scenarios include annual tune-up service on residential oil furnaces and boilers equipped with an oil filter housing.
Compatible with the 1A-25B, 1A-25A, and 77B oil filter housings as stated by the manufacturer.
Installation is performed by a qualified oil heat technician. Shut off the oil supply valve and relieve any line pressure before opening the filter housing. Dispose of the used cartridge and any residual oil in accordance with local environmental regulations. Follow applicable NFPA 31 guidelines when servicing oil-fired equipment.
