York SLM (Super Low Maintenance)

All the same benefits as the standard York but this compressor has several internal modifications to reduce oil consumption along with a finned head to dissipate heat more effectively, and a oil sight glass to monitor oil level. 

Side by side tests with a standard York show 1 oz of oil use per 1 hour runtime (standard) and 1 oz of oil use per 50 hours runtime (SLM).
