SF6 Gas Recovery Unit (GRU-7)

Whether you are looking for fast processing speed, better than 99.6% SF6 recovery, a 100% oil-less system, unlimited storage capacity, easy single valve operation, or portability, you will find it with the Enervac GRU-7. We developed the GRU-7 for our customers who found they needed more storage and recovery capacity than smaller handcart mounted units, but without the bulk and high price of a large skid or trailer mounted unit.
