The element does the filtering. The housing decides if it can.
Four material families, engineered to your duty: Clary-T stainless steel, Plastofilt polypropylene, Polyfilt uPVC, and FRP. Custom designs with no upper size limit, matched to the elements they hold, tested before dispatch.
Clary-T Stainless Steel
SS housings for cartridges and bags, from single-element to multi-round banks, including sanitary designs with CIP and SIP readiness for pharma and food. Twin-pod dual-orientation configurations keep continuous processes running through change-outs.
Plastofilt Polypropylene
Corrosion-proof PP housings for acids, alkalis, and salt-laden streams where stainless is the wrong answer. Light, chemically inert, economical at scale.
Polyfilt uPVC
uPVC housings for corrosive liquid duty at lower temperatures and pressures. The cost-effective choice for water treatment chemistry.
FRP Housings
Fiber-reinforced plastic housings, available off the shelf, for corrosive and coastal environments where metal housings corrode out in seasons.
Where each housing family works
Stainless Clary-T housings carry general industrial duty, sanitary pharmaceutical, biotech and food processing, sterile vent filtration, lenticular depth-module clarification, plate and frame and sparkler filtration, and high flow cartridge banks. Plastofilt polypropylene and Polyfilt uPVC housings serve corrosive chemistry, dyes and pigments, electronics, water and sewage treatment, and point-of-entry water. ClarySEA-M FRP systems serve seawater desalination and brackish water plants.
One-source advantage: because Gopani manufactures the bags, the cartridges, and the housings, fitment is guaranteed and one engineering team sizes the complete system: housing, elements, and change-out schedule, for your flow and solids load. Line data for every housing is in the tables below.

Conditions behind the numbers
Pressure ratings are maximum operating pressures at the stated temperature: Plastofilt at 8.0 bar and Polyfilt at 6 bar or 4.5 bar are rated at 21 C, and plastic housings lose pressure capacity as temperature rises. Flows are housing maximums for water; the element inside sets the real limit. Clary-T figures are preliminary and confirmed on the order drawing.
Elements that fit
Cartridge housings take DOE and SOE 222 or 226 elements from 10 to 40 inch, 6 inch high flow elements, lenticular modules and filter sheets. Bag housings take sizes #1 to #4 with PP collar or steel ring. Clary-T BF takes ClaryFil bags; Polyfilt BF takes size #1 and #2 bags with a PP collar.
Filter housings: direct answers
Which housing material should I choose?
Stainless Clary-T for pressure, heat, sanitary and solvent duty. Plastofilt polypropylene for acids, alkalis and salt-laden streams at up to 70 C. Polyfilt uPVC for corrosive water chemistry, UV and atmospheric exposure at up to 60 C. ClarySEA-M FRP for seawater and brackish water at large flows. Send the chemistry, pressure, temperature and flow and we recommend the family.
Is there a size limit?
No upper limit on Gopani-built housings. Stainless housings can be made in any stainless grade, and ClarySEA-M FRP systems run from 50 to 2000 m3/hr with 1 to 24 inch connections.
Which design codes can a Clary-T housing be built to?
ASME Section VIII Division 1, with U-stamp or UM-stamp; PED 97/23/EC with CE marking; or good engineering practice where no code applies, as the application requires. Clary-T Vent adds cGMP design. Tell us the code your site requires at enquiry, because it sets wall thickness, documentation and inspection.
What is the Mignon Plus housing?
A point-of-use housing for cold water that takes 5 inch M SX DOE cartridges of 50 mm outside diameter.
Can a housing change without stopping the process?
Yes, with a twin-pod dual-orientation Clary-T configuration: one pod stays on line while the other is serviced, so a continuous process keeps running through the change-out.
What we need from you for a firm recommendation
- Fluid chemistry, temperature and operating pressure
- Flow rate and the element type and rating inside
- Design code and documentation your site requires
- Connection type and size, and any sanitary or CIP and SIP need
- Site conditions: indoor or outdoor, coastal, UV exposure
What we can document
Each Clary-T housing is stated to undergo hydrostatic leak and burst pressure tests before dispatch. Clary-T lines are offered to ASME Section VIII Division 1 with U-stamp or UM-stamp, to PED 97/23/EC with CE marking, or to good engineering practice, as the application requires; Clary-T Vent adds cGMP design and an internal finish of Ra 0.4 micron or better, with documentation to the relevant standard; Clary-T Sanitary is stated as built to 3-A sanitary standards, documentation on request. Polyfilt housings are hydro-tested to 11 bar, and ClarySEA-M FRP systems are offered non-coded or to ASME Section X or BS 4994. Line specifications are marked preliminary and are confirmed on the order drawing.
Corrosive stream eating your housings?
Tell us the chemistry, pressure, and flow. We will recommend the material family and quote a housing engineered for the duty, not a catalog compromise.
