Filter housings
Series + core digits + material + pressure field + connection + nozzle layoutIdentify bag or cartridge housing first, then read quantity/size or quantity/length.
Define your need, then prepare the selection brief
For new equipment, replacement bags and cartridges, or an existing model: prepare the information for your task, then review filtration, specifications and installation.
What do you need to work on?
Choose a task to see the information to prepare and where to go next.
No model selected yet? Start with the filtration duty and site conditions.
Prepare the operating and installation details
- Fluid, composition, temperature and viscosity; list process and cleaning fluids separately.
- Contaminants, solids loading and filtration goal; identify the rating basis.
- Target flow, continuous or batch operation, operating pressure and allowable differential pressure.
- Piping sketch or site photographs, connection orientation, service clearance and maintenance method.
For existing equipment, check dimensions and interfaces before comparing media and ratings.
Prepare old-element photographs and specifications
- Full model, label and photographs; show the bag ring or both cartridge ends clearly.
- Actual length, diameter, bag size and end style; appearance alone does not establish interchangeability.
- Media, rating basis, seal material, contact fluid and temperature.
- Current flow, service life, replacement differential pressure and clogging or filtrate issues.
With a model, nameplate or drawing, confirm the series and revision before interpreting configuration fields.
Prepare the model and its document revision
- Full model, nameplate, order or drawing reference and document date.
- Identify a housing, bag or cartridge; codes are not interchangeable between series.
- List materials, quantity, rating, connections and port orientation to retain or change.
- Flag missing fields and units for review; finalize specifications against confirmed documents.
Start with the information you have. A model, photographs or drawings can help us review your requirements.
New equipmentTen operating inputs in four groups
Record the actual conditions and open questions. Include models, photographs or drawings, and complete missing details together.
Fluid and filtration goal
- Fluid and major composition
- Contaminant form, size and solids loading
- Target rating and basis: nominal, absolute, Beta Ratio or experience
Throughput and operating conditions
- Flow, unit and continuous or intermittent operation
- Operating pressure and allowable differential pressure
- Temperature, viscosity and solids content
Materials and application requirements
- Corrosive, solvent, oxidative, chloride or other chemical risks
- Food, pharmaceutical, sanitary, electronics or cleanliness requirements
Installation and maintenance
- Material, connections, installation space and flow orientation
- Existing filtration, current issues, cleaning, backwash or online-maintenance needs
From the brief to confirmed specifications
Narrow the product direction step by step, then review the model against operating conditions and installation drawings.
- Define the fluid and filtration duty
- Characterize contaminants and target rating
- Set flow, temperature, pressure and differential-pressure limits
- Check materials, connections, space and maintenance
- Build a candidate configuration and model structure
- Finalize against approved technical documents
Understanding filter model codesExpand when reviewing an existing code or its fields
Identify the family before interpreting its fields. Letters and numbers are series-specific. Each product page retains its own model guidance.
Filter cartridges
Series or media + target rating + length + end fitting + sealApplication, membrane, end and seal codes are series-specific.
Filter bags
Media prefix + target rating + ring + bag size + construction or additional codeBag size does not replace actual dimensions, ring, media construction or differential-pressure review.

After choosing a series, review wetted materials, element count, connection orientation and service clearance. Existing piping or equipment drawings help review the installation.
