Overview

Higher-capacity oil-free air for larger dental demand

The SL-140 combines a dual 850 W oil-free compressor system with a 12 gallon tank and 330 L/min rated air capacity. The product specifications identify the model as suitable for one to four units, making it a strong fit for multi-chair dental setups.

Standard equipment includes dual pressure gauges, an adjustable regulator with moisture filter, a pressure switch, and either 110 V or 220 V power selection. For cleaner downstream air treatment, customers can keep the base compressor, add a 2-stage dryer, or step up to the automatic dryer system.
