Abstract
A portable air compressor unit (10) having a housing (22) with a rear end (30) and front end (26). The housing (22) includes a rear louver (66) near the rear end (30), an exhaust outlet (74) near the front end (26) and a mid louver (70) between the rear and front end. A rear cooler set (82) and rear fan (106) are disposed within the housing between the rear louver and mid louver. The fan (106) draws cooling air into the housing through rear louver (66) and through the rear cooler set (82). A front fan (122) and front cooler set (130) are disposed within the housing (22) between the mid louver (70) and exhaust outlet (74).
