Products Description

Dust filtration bags are specially designed to trap airborne particulate matter in industrial processes. These bags reliably capture fine dust (down to 1 micron) with filtration efficiencies in excess of 99.9%.

We offer a range of materials (e.g. polyester, PTFE, Nomex) and sizes suitable for temperatures up to 500°F (260°C) and particle loads ranging from wood dust to metal fumes.

How It Works

Dust filtration bags operate on surface filtration and depth filtration principles:

1. Dust-Laden Air Entry

Contaminated air enters the baghouse system.

2. Particle Capture

Surface Filtration: Larger particles form a "dust cake" on the bag surface.

Depth Filtration: Submicron particles are trapped within the bag's fiber matrix.

3. Cleaning Cycle

Pulse-Jet Cleaning: Compressed air pulses dislodge dust cakes.

Shaker Mechanism: Mechanical vibration releases accumulated dust.

Dust Disposal: Collected particulates fall into a hopper for removal.

Technical parameters

Parameter	Typical Range	Notes
Temperature Rating	–20 °C to 177 °C (350 °F)	Up to 260 °C with aramid or glass fiber
Air-to-cloth Ratio	1.0–3.5 m³/min·m² (3–10 ft/min)	Application-dependent
Filtration Efficiency	≥99.9% for PM2.5–PM10	Exceeds regulatory requirements
Differential Pressure	50–150 Pa (0.2–0.6 in w.g.)	Initial; increases until cleaning pulse
Media Weight	200–600 g/m²	Heavier for abrasive or high-temp service
Pulse Pressure	4–6 bar (60–90 psi)	For pulse-jet cleaning systems

Key features

High Filtration Efficiency

≥99.9% capture of submicron particles due to fine-fiber media and dust cake formation.

Low Pressure Drop

Optimized airflow design reduces energy costs by 15–20%.

Durability

Reinforced stitching and anti-abrasion coatings extend service life under heavy dust loads.

Easy Maintenance

Standardized snap‑band or cuffed top designs enable quick bag replacement without special tools.

Applications

Power Generation: Fly ash removal from coal-fired boilers in 650 MW plants; reduced bag failure with reinforced aramid media.
Woodworking & Furniture: Sawdust and wood chip collection in mills, planing, sanding lines; PTFE bags prevent clogging from adhesive resins.
Food & Grain Processing: Flour and sugar dust control; FDA‑compliant PTFE membrane bags ensure hygiene and minimal product loss.
Metalworking: Capture of welding fumes and grinding dust; high‑temperature glass fiber media withstands heat.
Cement & Minerals: Clinker cooler and kiln exhaust filtration; robust polyester felt resists abrasion.
