Replacing both bags and cages?
Send the details together so we can review the assembly.
Industrial Dust Collection
Dust Collector Filter Bags and Cages
Manufactured to your collector’s dimensions, operating conditions and approved specification. ClipOn supplies replacement bags and cages, with technical support for media selection, reverse engineering and recurring performance problems.
Polyester, meta-aramid, PPS, P84, PTFE and fibreglass options, with application-specific constructions and finishes.
Filter Bags Made for Your Dust Collector
A replacement bag needs to fit the collector and withstand what happens inside it. Dust characteristics, gas chemistry, moisture, temperature excursions and the cleaning cycle all matter. So do the seams, cuff and the way the bag sits on its cage.
Share the specification you currently buy, or send a drawing and the application details. If it is performing well, we can quote against the agreed requirements. If it is failing early, tell us where the damage appears and what has changed in the process.
Filter Media Options
Confirm the required checks and documents in the quotation.
Filter media
Why it may suit your application
What we review before recommending it
Polyester
A practical choice for many dry, moderate-temperature dust collection duties.
Moisture at elevated temperatures, chemical exposure, abrasion and cleaning conditions.
Meta-aramid
For elevated-temperature duties where heat resistance and mechanical durability are important.
Moisture, gas chemistry, temperature excursions and the causes of any previous failures.
PPS
Often considered for hot, moisture-bearing gas streams where chemical resistance is important.
Oxygen and other oxidising constituents, operating temperature and process fluctuations.
P84 polyimide
Its multilobal fibre shape provides a large surface area for dust capture in suitable hot-gas applications.
Gas chemistry, moisture, temperature profile and the required media construction.
PTFE
For demanding duties requiring broad chemical resistance and high-temperature capability.
The complete exposure conditions, mechanical requirements and cost justification.
Fibreglass
For suitable high-temperature applications, with construction and finish selected for the collector.
Cleaning method, flexing, abrasion, cage support and chemical exposure.
A fibre name alone is not a finished specification. We also review fabric weight, permeability, support scrim, surface finish and any membrane requirement.
Blends and Finishes
A different fibre is not always the whole answer.
Sometimes the requirement calls for a different fibre blend. In other cases, the surface finish, supporting scrim or bag construction needs attention. We review these separately so that each proposed change has a clear purpose.
Application-specific blends
- ClipOn can evaluate constructions including aramid/P84 and polyester/aramid blends where the application justifies them.
- We agree the blend composition, construction and operating limits before manufacture.
- A blend does not automatically inherit the temperature or chemical resistance of its highest-performing fibre.
Surface finishes and functional constructions
Option
Why it may be considered
Singeing and calendering
To modify the media surface and support dust release, according to the selected construction.
Water- and oil-repellent treatment
To reduce wetting by moisture or oily dust where the treatment is suitable for the process.
PTFE-based treatment
To modify fibre or surface behaviour for selected dust-release and chemical-exposure requirements.
PTFE membrane
To provide a surface-filtration layer for fine-particle capture and reduced dust penetration into the underlying media.
Conductive / antistatic construction
Where the application requires specified electrical properties, considered alongside the collector’s earthing and explosion-protection arrangements.
Bag Construction and Fitment
Confirm the required checks and documents in the quotation.
Detail
What to confirm
Collector and cleaning
Pulse jet, reverse air or shaker design; existing drawing or equipment reference.
Bag geometry
Diameter or cross-section, finished length and dimensional tolerances.
Top and bottom
Cuff, snap band or other attachment; bottom shape and reinforcement.
Fabric construction
Fibre or blend, woven or nonwoven construction, weight and permeability.
Finishing
Membrane or treatment, seam construction and application-specific details.
Bag Types
Cylindrical, Cassette, Multi Channel RABH
Filter Cages & Venturis
The cage is part of the bag’s working assembly.
A replacement cage needs to do more than fit inside the bag. Its dimensions, wire arrangement, joints and surface condition affect bag support, installation and wear.
ClipOn manufactures filter cages and venturis to agreed drawings and specifications. For replacement requirements, we can work from an existing drawing or sample and clarify the dimensions needed to match the bag and collector.
Cage details
Specification
Details to agree
Geometry & dimensions
Profile, overall length, diameter or cross-section, and dimensional tolerances.
Wire & ring arrangement
Number and diameter of longitudinal wires; support-ring spacing.
Material & surface protection
Base-metal grade and any required coating or surface treatment, specified separately.
Top, base & venturi
Connection details, base construction, venturi dimensions and attachment, where required.
Sectional construction
Number of sections, joint design and available installation clearance.
Bag & collector fit
Compatibility with the bag dimensions, fixing arrangement and collector interface.
Ordering cages only?
Share your drawing or sample details, quantity and delivery location. We will identify any additional information needed.
Applications
Filter bags and cages are used in cement and lime production, steel and foundry operations, aluminium and alumina processing, power and ash handling, minerals, chemicals and other dust-generating processes. The process point matters more than the industry label: a transfer point and a hot process exhaust can require very different specifications.

Before You Replace It Understand It
Recurring bag failure is a reason to review the duty before repeating the order. Send the existing specification, operating information and photographs showing the failure location. Our Replacement Review starts with the evidence you have.
Review outcome
What you receive
Repeat
Confirmation that the available information supports retaining the existing specification
Modify
A proposed change with the technical reason and the conditions it is intended to address.
Investigate further
The missing information or further checks needed before a responsible recommendation can be made.
Dependable Supply Starts with an Agreed Specification
Before production, we agree the product details, quantity, required checks and dispatch commitment. Any proposed substitution needs your agreement. If something changes during the order, we communicate it so you can plan.
For export enquiries, include the destination, required delivery date and any inspection or documentation requirements. Dispatch timing and freight transit time are confirmed separately.
Send Your Filter Bag or Cage Requirement
Send a drawing, RFQ, previous specification or part number with supporting details. Include quantity, destination, normal and peak temperature, dust or process description, and cleaning method. For an urgent requirement, state the date you need it and send the details by WhatsApp or email.
Do not have every detail? Send what is available. We will identify what needs confirming before a quotation or production approval.
Frequently Asked Questions
Yes. Send the part number with a drawing, datasheet or clear photographs where available. A sample can help establish dimensions and construction, but the material and operating requirements still need confirmation. We will agree sample handling before you send it.
Yes. Send the bag and cage details together so we can review the assembly as a working unit and confirm fit, fixing and any venturi requirements before quotation.
Sometimes. We review whether a fibre blend, surface finish, scrim or construction change is justified for the duty. A blend does not automatically inherit the temperature or chemical resistance of its highest-performing fibre.
Not always. High differential pressure can come from dust characteristics, cleaning performance, media selection, bag condition or collector issues. Share operating data and failure evidence so we can review before changing the specification.
Emission performance and service life depend on process conditions, installation and maintenance. We agree the product specification and the checks we will perform; guarantees for emission or life need agreed operating limits and are confirmed case by case.
Normally around 4 weeks production; urgency and development are reviewed case by case. Delivery time is confirmed separately.
Repeat orders can proceed against an agreed specification. If operating conditions, failures or requirements have changed, tell us before we manufacture so we can confirm whether the previous specification still applies.
