1619-3804-09 Atlas Copco OEM Drive Coupler

The 1619-3804-09 Atlas Copco OEM Drive Coupler is an OEM Stromag Periflex-style coupling for Atlas Copco portable compressor platforms. Atlas Copco specifies Stromag couplings in several of their diesel-driven portable models where the Periflex flywheel-mount design provides the optimal engine-to-airend connection.

The Periflex coupling bolts directly to the engine flywheel and uses a disc tire element to provide torsional damping. The plug-in design allows element replacement without disturbing engine or airend alignment, which simplifies field service. Atlas Copco portable compressors equipped with Periflex couplings are mid-range to large units serving construction and mining support applications.

The 1619-3804-09 is a direct OEM replacement. Follow Atlas Copco’s service procedure for disc tire replacement and verify axial spacing before startup.
