Product overview
A polypropylene felt filter bag in multiple sizes, ring styles and constructions.
A lightweight polypropylene-fiber bag suited to prefiltration and particle capture across a range of general liquid duties.
- Series
- PP
- Selection priorities
- Media, rating basis, actual dimensions, ring, construction, temperature and chemical compatibility
Working principle
Polypropylene felt bags retain liquid-borne particles in a PP fiber layer and can be selected around a prefiltration duty.
Construction & flow path
The PP bag body, ring and seams form an element supported by the housing basket. Bag differential-pressure limits are separate from housing pressure ratings.
Applications & filtration duty
A selection direction for particle prefiltration of water, cleaning liquids and general process fluids, with media and rating reviewed for the actual liquid.
Technical parameters
Use these specifications for selection. Materials, dimensions and operating conditions follow the selected model and agreed specification.

Operation & maintenance
- Media temperature reference
PP media temperature reference: ≤92 °C. Review ring, construction and fluid to determine the complete bag temperature limit.
- Maximum element differential pressure
Bag differential-pressure reference: 1.75 bar; review the fluid, temperature and support basket for the application.
- Recommended replacement differential pressure
1.03 bar; review the actual replacement trigger for the duty.
Connections & installation
- Ring-style codes
G=inward-turned plastic ring; F=outward-turned plastic ring; S=steel ring; SS=stainless steel ring. Confirm the plastic material for the actual version.
Configuration & supply scope
- Fabrication codes
Blank=stitched; WE=heat-welded.

Information to prepare for an inquiry
Use this family’s selection priorities to share available operating conditions, equipment information or drawings.
- Confirm fluid composition, temperature and PP compatibility.
- Provide normal/peak flow and expected solids load.
- Specify bag size, ring and sewn or welded construction.
Operation & maintenance
Record pressure drop and bag-change intervals. Clean the basket and ring seat during changes to avoid carrying retained debris to the clean side.
Common operating inputs
- Fluid and major composition
- Target flow and operating pattern
- Operating temperature and pressure
- Contaminant form and target rating
- Material, connection and space constraints
- Maintenance frequency and existing equipment
Discuss this product’s configuration
Share the fluid, operating and installation conditions to review suitable specifications.
Products can be configured around the actual duty. Final specifications follow the quotation, drawing or technical agreement confirmed by both parties.
