320 * 660 dust collector dust filter cartridge ultra efficient filtration

320 * 660 dust collector dust filter cartridge ultra efficient filtration

1、 Core Parameters (Ultra Efficient Version)

Filtration area: 8-12 square meters (2-3 times the size of a regular filter cartridge)

Filtering accuracy: 0.3 μ m level, intercepting ultrafine dust

Filtration efficiency: ≥ 99.97% (H13); 99.999% for 1 μ m

Rated air volume: 1800-2400m ³/h (single unit)

Initial resistance: 120-150Pa (low resistance energy-saving)

Cleaning method: Pulse back blowing (0.4-0.6MPa)

End cap/frame: electroplated zinc/anti-corrosion; Sealing: Nitrile rubber

2、 Filter material configuration (key to ultra-high efficiency)

Standard efficiency: Polyester long fiber non-woven fabric 0.5-5 μ m, efficiency ≥ 99.9%

Ultra efficient (PTFE coated): Polyester substrate+PTFE nanopore membrane 0.3 μ m, H13 grade, surface filtration, non stick dust, easy to clean, and resistant to hydrolysis

Anti static/flame retardant: adding conductive fibers/flame retardant substrates to adapt to explosion-proof/high-temperature scenarios such as lithium batteries, coal powder, welding, etc

3、 Performance advantages

Ultra efficient and low emission: H13 level, export dust ≤ 3mg/m ³, meets the new national standard.

Low resistance and energy-saving: With a large filtration area, low filtration speed, and low resistance, the energy consumption of the fan is reduced by 20-30%.

Dust removal: PTFE coating+wide pleat spacing dust removal rate ≥ 98%, stable resistance, long service life.

Durable and washable: The laminated filter material can be washed and reused, with a lifespan of 6-12 months and low maintenance costs.

Strong adaptability: universal for upper/oblique insertion/side installation, can directly replace imported filter cartridges of the same specifications.

4、 Typical application scenarios

Welding/cutting fumes (steel structures, automotive manufacturing)

Lithium battery materials (graphite, lithium iron phosphate) ultrafine dust

Sandblasting/shot blasting, grinding and polishing high concentration dust

Coal powder, flour, feed and other flammable and explosive dust

High cleanliness requirements for chemical, food, pharmaceutical and other working conditions

5、 Selection and installation points

Filter material selection: PTFE coating+anti-static for ultrafine/explosive dust; Choose polyester for ordinary dust.

Installation method: prioritize vertical installation (dust removal); Diagonal insertion saves space.

Ash cleaning parameters: pressure 0.4-0.6MPa, cycle 60-120min (adjusted according to concentration).

Replacement cycle: Replace when the resistance is ≥ 800Pa or the efficiency significantly decreases.

6、 Common models and replacements

Universal models: 320 × 660 × 220 (inner diameter), 320 × 660 × six ear

Alternative: Nederman, HERR, AMANO imported filter cartridges of equivalent specifications
