You can switch from one to the other instantly
The emergence of new, more effective filter bag materials has challenged the popular filter cartridge. Filter bags are now an attractive, economical alternative to cartridges in many applications. Bags cost less, are easier to install and remove, and require less room in storage and disposal.
The convertible filter housings from offers you the ability to use filter bags in place of cartridges without burning your bridges behind you. You can always change back to cartridges, for whatever reason.
Flow Rates
Ecologix' convertible filter housings are offered in two diameters to hold 3 and 5 cartridges, respectively. The 3-cartridge housings are nominally rated at 70 gpm*. The 5-cartridge Series housings are nominally rated at 100 gpm*. These ratings are governed by the restrictive openings in the cartridge support plate. They do not take into account the pressure drops imposed by the bags or cartridges used.
Pictured is a Model 6330. It can hold three 30-in. long cartridges (shown inserted) or a filter bag and support basket (at left). The two 3/4-in. ports at the bottom of the housing are 1) a dirty liquid drain (upper port), and 2) a clean liquid drain (lower port). The dirty liquid drain need not be used when filter bags are employed; if bags are properly removed, no dirt washes off downstream. (The use of a liquid displacer makes this easier to do.)
