GUANLIN foundry anti-static filter bag, 130°C flame retardant for metal dust and sand handling collection.
Flame retardant anti-static filter bags for foundry shakeout, sand handling and metal grinding, combining spark resistance with static dissipation for reactive metal dust.
Description
Foundries generate the classic dual hazard: reactive metal dust that ignites easily, and static charge generated by dry sand and metal particles moving through ducts. Both protections are needed on the same bag, and they must survive the abrasion of sand handling. GUANLIN foundry bags combine flame retardant treatment with a conductive grid in a 500 g/m² polyester felt.
Why Choose GUANLIN Foundry Filter Bags
- Dual protection — flame retardant treatment plus conductive grid in one media.
- Abrasion resistance — 500 g/m² felt with reinforced seams for sand and metal dust.
- Static dissipation — surface resistance ≤10⁶ Ω with proper grounding.
- Spark resistance — self-extinguishes after the ignition source is removed.
- ≥99.9% efficiency — captures fine metal and sand dust down to 1 μm.
- Custom sizing — Ø115–200 mm × 1000–6000 mm.
Application Scenarios
Shakeout and knockout
Hot sand and metal particles with heavy abrasion and ignition risk.
Sand handling and reclamation
Dry sand generates static continuously; conductive media is essential.
Grinding and fettling
Metal dust with sparks from dry grinding.
Shot blast
Abrasive and hot particles in the extraction duct.
Die casting and melting
Fine metal fume with intermittent sparks.
Aluminium and magnesium processing
Reactive fines needing both static control and spark resistance.

FAQ
Q1. Why both flame retardant and anti-static?
Metal dust and dry sand create ignition and static hazards simultaneously.
Q2. Does grounding still matter?
Yes — cage, tubesheet and baghouse must be bonded and grounded.
Q3. Will it handle hot sand?
Short-term peaks to 150°C only; quench or cool if higher.
Q4. MOQ and lead time?
10 pcs, 7–15 days.
