Medium Temperature Duster Bags 中温除尘滤袋

Our medium-temperature dust filter bags are produced from four kinds of industrial needle-punched felt: Acrylic, Mid-high Temp Felt, PTFE and PPS. Different grammage, thickness and temperature resistance cover diversified medium and high-temperature flue gas and corrosive dust working conditions. Continuous operating temperature ranges from 160℃ up to 260℃, widely matched with pulse baghouse dust collectors for power plants, cement factories, waste incineration, chemical plants and metallurgy industry. All filter sleeves support customized diameter, length and top structure (elastic ring / steel snap band). Optional post-treatment including singeing, PTFE coating, water and oil repellent finishing is available on demand.

1. Acrylic Needle Felt Filter Bag

Core Advantages: Cost-effective mid-range material with good acid and alkali resistance; stable continuous working ≤160℃, instant peak temp up to 180℃.

Best use: Medium-temp slightly corrosive flue gas, asphalt mixing plant, common industrial boiler, construction material factory dust removal.

2. Mid-high Temperature Needle Felt Filter Bag

Core Advantages: Improved high-temperature formula, instant heat resistance up to 190℃, good acid and alkali tolerance with competitive price.

Best use: Small coal-fired boiler, asphalt station, medium-high temp waste gas without severe chemical corrosion.

3. PPS Needle Felt Filter Bag

Core Advantages: Excellent acid and superior alkali dual resistance; continuous working ≤190℃, instant peak at 232℃, outstanding hydrolysis resistance for sulfur-containing acidic flue gas.

Best use: Coal-fired thermal power plant, domestic waste incinerator, cement kiln tail, acidic boiler exhaust dedusting.

4. PTFE Needle Felt Filter Bag

Core Advantages: Ultra high heat resistance and premium chemical inertness; excellent acid resistance, good alkali stability; long-term working ≤260℃, instant peak temp up to 280℃, longest service life under extreme corrosive environment.

Best use: Strong acid and alkali chemical exhaust, hazardous waste high-temperature incineration, ultra-corrosive industrial flue gas purification.

Core Technical Spec Table

Medium-temperature dust filter bags are widely applied for flue gas treatment in thermal power plants, cement plants, municipal solid waste incinerators, chemical factories, asphalt mixing plants, iron and steel metallurgy, lime kilns, non-ferrous metal smelting and industrial boiler exhaust purification.
