Bud Air Vent IPV-1116
The Bud Industries IPV-1116 Vent is used to equalize internal and external temperature and pressure, and to prevent internal condensation in your enclosure. The vent comes with the housing, gasket, and locking nut. The vent requires a 3.5" hole in your enclosure. There are internal holes to mount a 80mm fan to the locking ring. This is the larger version of the IPV-1115.
