GUANLIN tension spring filter cage, compressible bag support frame for long bags and restricted access baghouses.
Compressible tension spring cages that hold filter bags under controlled axial tension, preventing sag and bag-to-bag contact while shipping compactly for long bag installations.
Description
Tension spring cages replace the rigid wire cage in baghouses where bags need to be compressed, transported compactly, or fitted through tight access openings. GUANLIN tension spring cages hold the bag under controlled axial tension, keeping the felt taut against the venturi and preventing the sagging that causes bag-to-bag contact and uneven dust loading.
Why Choose GUANLIN Tension Spring Cages
- Controlled axial tension — keeps the bag taut along its full length, avoiding sag and bag-to-bag contact.
- Compact transport — springs compress for shipping, cutting freight volume on long bags.
- Easy installation — fits through restricted access openings where rigid cages cannot pass.
- Stainless or galvanised — matched to the dust chemistry and temperature.
- Integrated venturi — aligned to the bag throat for efficient pulse induction.
- Custom sizing — Ø115–200 mm × 1000–6000 mm.
Application Scenarios
Baghouses with restricted access
Where the clean air plenum is tight or access hatches are small, a rigid cage cannot be threaded in; the compressible spring cage can.
Long bag installations
Long bags sag under their own weight on a rigid cage; axial tension keeps the felt straight and evenly loaded.
Overseas shipment and export packing
Compressed springs dramatically reduce shipping volume for long cages, lowering freight cost per set.
Retrofit of sagging bag systems
Where existing bags sag and touch each other, converting to tension spring cages restores clearance without changing the collector.
Cement and mineral plants
Abrasive dust combined with long bags benefits from even tension and reduced contact wear.
Food and chemical processing
Stainless spring cages suit wash-down and inspection-friendly installations.
Applicable Working Conditions
- Compatible with polyester, PPS, aramid and fiberglass filter bags
- Pulse jet cleaning with venturi induction
- Restricted access or long bag installations
- Export shipping where packing volume matters

FAQ
Q1. What is a tension spring cage?
A compressible cage that holds the bag under controlled axial tension instead of rigid support.
Q2. Why use one?
It prevents sag on long bags and passes through restricted access openings.
Q3. Does it ship compactly?
Yes, the spring compresses for shipping, reducing freight volume.
Q4. Can you match my bag size?
Yes, send the drawing.
