Description
The SaniFlow STE-G is an AISI 304 stainless steel housing for one or three 7″ filter bags with a plastic ring, in size #1 (17″) or #2 (32″). It is used for reverse osmosis pretreatment, water treatment and clarification, fuel filtration, and as a prefilter ahead of cartridges or membranes.
The liquid enters through the upper side connection, drops into the bag and passes through it from inside to outside: the solids stay in the bag and leave with it at changeout, so the housing stays clean. A perforated stainless steel sheet basket supports the bag along its full length against the differential pressure.
The lid closes with swing bolts and a handle: it opens without removing the bolts, and the bag is lifted out by its ring. It operates up to 10 bar, connects with a 2″ or 4″ flange or a 2″ thread, and is supplied with an industrial finish or with the interior polished to Ra < 0.8 µm and a matte exterior. We manufacture it at our stainless steel fabrication plant in Argentina.
Dirt stays in the bag
Inside-to-outside flow keeps the solids inside the bag: they leave with it at changeout and the housing stays clean.
For high solids loads
The bag holds a large amount of solids before changeout. The three-bag housing triples the filter area in a single unit.
Quick changeout
Lid with swing bolts and a handle: it opens without removing the bolts, and the bag is lifted out by its ring.
Supported bag
A perforated stainless steel sheet basket supports the bag along its full length against the differential pressure.
ExoBag® bags from 1 to 1,000 µm
Polypropylene, polyester or nylon, depending on the fluid and the temperature.
AISI 304 stainless steel
Industrial finish, or interior polished to Ra < 0.8 µm with a matte exterior. Made at our fabrication plant in Argentina.

Frequently asked questions
Which bags does the STE-G accept?
7″ (Ø 7 1/16″) filter bags with a plastic ring, in size #1 (17″) or #2 (32″): one in the single-bag housing and three in the three-bag housing. ExoBag bags range from 1 to 1,000 µm, in polypropylene, polyester or nylon.
When should the bag be changed?
When the differential pressure reaches 1 bar; do not exceed 1.8 bar. Open the lid, which has swing bolts, and lift the bag out by its ring, with the solids inside. Before closing, check that the ring sits evenly on the basket and inspect the lid gasket.
When is the three-bag housing the right choice?
When more filter area is needed: the three-bag housing triples it in a single unit. The catalog model, STE-03G, holds three 32″ bags in a Ø 450 mm body, 1,100 mm long.
What connections does it have and what pressure does it handle?
Upper side inlet and bottom outlet, with a 2″ flange, a 2″ thread or a 4″ slip-on flange (T, W or X in the ordering code). It operates up to 10 bar (150 psig).
What information do you need to select it?
Normal and maximum flow rate, fluid and viscosity, temperature, solids size and load, and the line connections. With that we confirm the number and size of the bags, the right ExoBag bag and the connection.
