All C-Aire riser mount compressors ship with our patented riser bracket system, which is the quickest and easiest mounting system in the industry! The S33R is best suited for single-valve small standard systems and pre-action systems. Our Digital Air Maintenance Device allows users and techs to set the system pressure properly in seconds! Our patent-pending Leak Detection shows techs and owners how many times the system has run in the past 24 hours and 7 days! This is a quick and easy way to quantify how leaky a system is.
