KleenVent KV reservoir isolators protect against dust, chemicals, water vapor, and other contaminants through a breather vent. They reduce varnish build-up and extend oil and filter life. Eight models have capacities from 2.5 to 80 gal; polyglass shells for 2.5-, 5-, 10-, and 20-gal models; and steel shells for 20-, 40-, 60-, and 80-gal models. They come in Buna-Nitrile, Butyl, Fluorocarbon elastomer, and Ethylene Propylene.
