Air systems has designed a unique stainless steel cart with a color-designated control panel to allow one side of the panel to be used for primary respirator breathing air and one side for tool/secondary air requirements. A low pressure whistle alarm is used on the yellow side of the panel and a low pressure bell is used on the blue side of the panel, both alarms activate if the auxiliary inlet is used as the primary air supply. The standard features of the TECH-RESCUE Cart make it the most versatile and unique air cart in the fire service industry.
