Custom Fire Apparatus, Inc. <br />The air compressor provided for the engine shall be a Wabco® SS318 single cylinder pass -through drive <br />type compressor which shall be capable of producing 18.7 CFM at 1200 engine RPMs. The air <br />compressor shall feature a higher delivery efficiency translating to more air delivery per horsepower <br />absorbed. The compressor shall include an aluminum cylinder head which shall improve cooling, reduce <br />weight and decrease carbon formation. Superior piston and bore finishing technology shall reduce oil <br />consumption and significantly increasing the system component life. <br />AIR GOVERNOR <br />An air governor shall be provided to control the cut -in and cut-out pressures of the engine mounted air <br />compressor. The governor shall be calibrated to meet FMVSS requirements. The air governor shall be <br />located on the air dryer bracket. <br />MOISTURE EJECTORS <br />A heated, automatic moisture ejector with a manual cable actuated drain provision shall be installed on <br />the wet tank of the air supply system. Manual cable actuated drain valves shall be installed on all <br />remaining reservoirs of the air supply system. The actuation pull cables shall be coiled and tied at each <br />drain valve. The supplied cables when extended shall be sufficient in length to allow each drain to be <br />activated from the side of the apparatus. <br />AIR SUPPLY LINES <br />The air system on the chassis shall be plumbed with color coded reinforced nylon tubing air lines. The <br />primary (rear) brake line shall be green, the secondary (front) brake line red, the parking brake line <br />orange and the auxiliary (outlet) will be blue. <br />Push to connect type fittings shall be used on the nylon tubing. All drop hoses shall include fiber <br />reinforced neoprene covered hoses. <br />AIR TANK SPACERS <br />There shall be spacers included with the air tank mounting. The spacers shall move the air tanks 1.50 <br />inches inward towards the center of the chassis. This shall provide clearance between the air tanks and <br />the frame for body U-bolt clearance. <br />REAR AIR TANK MOUNTING <br />If a combination of wheel base, air tank quantity, or other requirements necessitate the location of one or <br />more air tanks to be mounted rear of the fuel tank, these tank(s) will be mounted perpendicular to frame. <br />WHEELBASE <br />The chassis wheelbase shall be 232.00 inches. <br />REAR OVERHANG <br />The chassis rear overhang shall be 100.00 inches. <br />FRAME <br />07/26/22 <br />-30- <br />
