Some CAF systems are equipped with an air only outlet, generally mounted on or near the pump panel. This outlet is useful for air only needs where foam solution would be undesirable. This outlet can be used to air up tires, recharge extinguishers, other air tools, or just as an air blower for cleaning air filters, blowing dust from a cab or blowing leaves, and as the air outlet necessary for the CAF system Warm Up Check.
