This new XD4000 Continuous-Duty model is the ultimate for extensive compressed air performance. Unit features an exclusive, forced air, motor and compressor cooling system. The specially designed deep-finned head, and compressor body is cooled by a 100cfm fan built into a housing shroud, which also adds protection to the unit. An internal fan also cools the modified 5hp electric motor. This cooling combination provides superior operating temperature reduction resulting in an unrivaled 100% duty-cycle @ 200psi.
