The Night Vision Optics Purge Kit from N-Vision is an efficient portable kit used to evacuate air from night vision devices and backfill the system with dry nitrogen. This procedure eliminates contaminants and moisture from the optical housing that can degrade performance of the night vision device.
The purge kit operates via an easy-to-operate manual vacuum pump that requires no electricity. This rugged lightweight kit (only 34 lbs) contains all the components needed, including a 20 cubic feet gas cylinder for purging night vision devices both at the maintenance facility and in the field. A variety of purge adapters are available to purge almost any type of night vision equipment, the kit includes adapters for PVS-7 and PVS-14 night vision goggles.
