BelAire 1312100139 V-Belt

The BelAire 1312100139 V-Belt is a 66-inch outer-diameter classical V-belt that transfers power from the electric motor to the compressor pump in BELAIR two-stage stationary air compressors (models 318VL and 318HL). Constructed from reinforced rubber with polyester or aramid tensile cords, it provides torque transmission through friction between belt and pulley grooves, and its cross section is application dependent. This OEM-equivalent belt is designed for industrial and commercial compressed air systems and is commonly used for routine maintenance, replacement of worn belts, and restoration of compressor performance. It supports reliable operation in manufacturing plants, automotive shops, maintenance facilities, and other industrial environments that rely on BELAIR stationary two-stage compressors. Common replacements include BELAIR 1312100139 OEM V-Belt, Gates 66-inch Industrial V-Belt, and Browning 66-inch Classical V-Belt equivalents.
