Need lots of air but have very little space? This is the perfect configuration for the 15 and 20HP demand. The 2 scroll heads are horizontally positioned with the serpentine belt on the lower portion of the skid allowing for easy access for maintenance. The desiccant dryers are mounted on the back along with the filters, dewpoint monitor and CO monitor required for a complete NFPA 99 medical air package. This configuration is the smallest on the market for a 20HP Medical Air Package with System Health and can accommodate up to 240 gallon receiver.
