GUANLIN industrial dust collector filter cage, galvanised and stainless steel bag support frame for pulse jet baghouse.
Automated-welded filter cages with integrated venturi and burr-free silicone coating, keeping bag-to-cage clearance consistent and protecting filter bags from abrasion in pulse jet baghouses.
Description
A filter bag performs only as well as the cage inside it. A cage that is out of round, has weld burrs, or sits high in the tubesheet wears through the felt in weeks and leaks dust at the snap band from day one. GUANLIN cages are welded on automated lines, straightened after welding, coated burr-free and fitted with an aligned venturi.
Why Choose GUANLIN Filter Cages
- Automated welding — consistent wire spacing and roundness, batch after batch.
- Burr-free silicone coating — reduces felt abrasion at contact points.
- Integrated venturi — aligned to the bag throat for efficient pulse induction.
- Correct snap band seat — bag seats fully in the tubesheet.
- Galvanised or stainless — standard duty or corrosive/high temperature.
- Custom sizing — Ø115–200 mm × 1000–6000 mm to your bag drawing.
Application Scenarios
Woodworking and furniture extraction
Sawdust is mildly abrasive; a straight coated cage keeps the bag concentric so wear stays even rather than concentrating on one line.
Cement and mineral processing
Clinker dust is highly abrasive — cage roundness plus coating is the difference between a six-month bag and a two-year bag.
Steel and foundry baghouses
Heavy dust loading flexes the bag against the cage thousands of times daily; silicone coating reduces that wear.
Chemical and powder processing
New coated cages avoid residue and corrosion products contaminating the batch.
Food and flour milling
Stainless cages suit wash-down and inspection regimes.
Retrofit and replacement
Replacing worn cages with the bags restores original clearance and cleaning performance.
Applicable Working Conditions
- Compatible with polyester, PPS, aramid and fiberglass bags

Yes, integrated and aligned.
Q4. Can you match my bag size?
Yes, send the drawing.
