Introduction
The units used throughout this manual conform to the SI international system of units of measurement.
1.2 General Description
The FL20K has been developed for use in clean pumping systems to prevent the back-migration of rotary pump oil
vapour into the systems; we particularly recommend that you use an FL20K with two-stage rotary pumps.
The component parts of the FL20K are illustrated in Figure 1. The FL20K consists of a metal basket (4) located within
a cast aluminium body (3), the metal basket is secured in place by a knurled nut (1), lid (6) and spring (5).
A sorbent is contained in the metal basket to absorb any oil which back-migrates from the pump. The sorbent
material used is activated alumina which has exceptional trapping properties for oil vapour. It has a long life (up to
six months) before it becomes saturated and has to be renewed.
