GUANLIN filter bag and cage set, 130°C temperature resistance, for woodworking and cement baghouse dust collection with matched snap band fit.

Buying bags and cages separately is the most common source of fit problems in a baghouse: a bag that is slightly too long bunches on the cage, a cage that is slightly out of round wears through the felt in weeks. GUANLIN supplies the bag and its cage as a matched set, so the snap band locks into the tubesheet, the venturi aligns, and the clearance between bag and cage is correct from the first installation.

Why Choose GUANLIN Bag and Cage Sets

1. Matched fit — bag and cage produced to the same drawing, so the bag seats fully and wears evenly.
2. Integrated venturi — the cage venturi is aligned to the bag throat, maximising pulse jet induction.
3. Burr-free cage finish — silicone or organic coating prevents the cage wires from abrading the felt.
4. Stable 130°C service — polyester needle felt rated 130°C continuous, 150°C peak.
5. ≥99.9% filtration efficiency — dense needle-punched felt captures fine particulate down to 1 μm.
6. One purchase order — bags, cages and venturis arrive together, cutting lead time and freight.
7. Custom sizing — Ø115–200 mm × 1000–6000 mm to your drawing.
8. Replacement-friendly — order the exact set again by SPU for consistent future maintenance.

Application Scenarios

Woodworking and furniture manufacturing
When a workshop replaces bags but reuses worn cages, the new bags fail early. Supplying the set together removes that trap: fresh felt on a straight, burr-free cage gives the full service life the media is designed for.

Cement and mineral processing
Abrasive clinker dust attacks any misalignment. A matched set keeps the bag concentric on the cage, so wear is even and the bag does not rub through on one side.

Flour milling and food processing
Hygiene programmes require full replacement of contaminated components. Receiving bag and cage as one sealed set simplifies changeover and traceability.

Foundry and shot blast extraction
Heavy dust loading and frequent pulse cleaning demand a cage that stays round and coated; the matched set is built for that duty.

Chemical and powder processing
Where product contamination matters, a new cage with the new bag avoids residue carried over from the previous campaign.

Scheduled maintenance and shutdowns
Planning a shutdown is easier when one SPU covers the whole assembly — count, order and install without matching parts on site.

FAQ

Q1. Why buy the bag and cage together?
They are produced to the same drawing, so fit, clearance and venturi alignment are correct from the first installation.

Q2. Can you match an existing cage?
Yes, send the cage drawing or a sample and we produce bags to suit.

Q3. What is the maximum temperature?
130°C (266°F) continuous, 150°C short-term peak for the standard polyester set.

Q4. Is the cage coated?
Standard galvanised wire with silicone coating available to reduce felt abrasion.

Q5. What is the MOQ?
10 sets.

Q6. What is the lead time?
7–15 days for standard sizes.

Q7. Can I reorder the same set later?
Yes — quote the SPU and we reproduce the identical bag and cage.
