GUANLIN pulse jet filter cage, galvanised wire support frame with venturi for reverse pulse baghouse systems.
Galvanised pulse jet filter cages with integrated venturi and burr-free coating, sized to match standard baghouse tubesheets and filter bag collars.
Description
Pulse jet cleaning only works if the cage and venturi are right. The venturi is what induces the secondary air that carries the pulse pressure wave down the full length of the bag; if it is misaligned or the wrong profile, the top third of the bag cleans well and the bottom two thirds stay loaded. GUANLIN pulse jet cages are welded with an integrated venturi profiled to the bag throat.
Why Choose GUANLIN Pulse Jet Filter Cages
- Integrated venturi — profiled and aligned to the bag throat for full-length pulse induction.
- Automated welding — consistent wire spacing and roundness.
- Burr-free coating — protects the felt at every contact point.
- Correct snap band seat — bag seats fully in the tubesheet.
- Galvanised or stainless — matched to the dust chemistry.
- Custom sizing — Ø115–200 mm × 1000–6000 mm.

Application Scenarios
Reverse pulse baghouses
The venturi is the critical feature; without it pulse cleaning is uneven along the bag.
Cement and mineral plants
Abrasive dust demands round, coated cages.
Steel and foundry
Heavy dust loading with frequent pulse cycles.
Chemical and powder processing
Correct clearance avoids product bypass and abrasion.
Retrofit with new bags
Replacing worn cages restores original cleaning performance.
High dust concentration systems
Even pulse distribution matters most at high loading.

FAQ
Q1. Why does the venturi matter?
It induces secondary air that carries the pulse down the full bag length.
Q2. Will it fit my tubesheet?
Send the bag drawing and tubesheet hole size to confirm.
Q3. Should I replace cages with the bags?
Yes — worn cages wear out new bags quickly.
Q4. MOQ and lead time?
10 pcs, 7–15 days.
