Frequently Asked Questions
Which filter bag material suits a coal-fired power plant?
PPS felt bags are the standard for coal-fired baghouses, offering sulfur and heat resistance. PTFE-membrane PPS bags are used where finer emission limits apply.
How do I select dust collector filter bags?
Match media to gas temperature, moisture and chemistry first, then to emission limits: PET for dry generic dust, PPS for acidic coal flue gas, Nomex for dry heat, membrane laminates for strict PM limits.
Do you make custom bag sizes?
Yes — every dust filter bag is sewn to your tube sheet diameter and length, with snap-band, flange or ring tops.
Are anti-static filter bags available?
Yes — anti-static felt bags (carbon-scrim / conductive yarn) for explosive dust applications.
What is the difference between singed and membrane finish?
Singed surfaces improve cake release cheaply; PTFE membrane laminates capture fine dust on the surface and serve the strictest emission limits.
