3G Slim Line Series

Pentair Pentek 3G Slim Line Housings are the perfect choice for low-flow filtration applications. Their slim design and high chemical compatibility make them ideal for those challenging applications.

Caps are manufactured from reinforced polypropylene in black, blue, and white. Three different style caps add to the flexibility of these housings. The mounting bracket cap allows the housing to be mounted to a single or multiple housing bracket.

The bracket is built into the integral bracket cap. The meter mount cap’s gauges indicate when the cartridge is dirty and allow you to get the most out of your cartridges.

Housings are available with either clear or opaque sumps with the clear housings being manufactured of Styrene-Acrylonitrile (SAN) and the opaque housings are polypropylene. Clear housings offer on-site examination of the flow, cartridge life and performance. Opaque housings are molded from reinforced polypropylene and offer outstanding chemical compatibility.
