The S281R is more compact, easier to install, and quieter than the S261R. New for the S281R is our fully-redesigned and upgraded Digital Air Maintenance Device Gen-3 with Leak Detection (patent-pending). The Digital AMD Gen-3 is UL listed and allows the user to set the system pressure in seconds and measure system air leaks by monitoring the total number of starts in the past 24 hours and 7 days. All C-Aire riser mount compressors ship with our patented riser bracket system, which is the quickest and easiest mounting system in the industry! Whisper quiet, compact units that are specifically designed for settings where noise is a concern. These units are oil-free, easy to install, and low maintenance.
