Dust removal air filter cartridges – four grades, matched airflow.rs of Dust Removal Air Filter Cartridges

1. Introduction

Aite Dust Removal Air Filter Cartridges are the core consumables of industrial pulse dust collectors – serving as the key

 component to guarantee stable dust separation performance. Aite Dust Removal Air Filter Cartridges are widely deployed 

in metallurgy, cement, woodworking, chemical coating, sandblasting, food processing, pharmaceutical production, 

and workshop waste gas purification systems. Two decisive indicators determine purification efficiency, equipment energy

 consumption, and service life: filtration precision (dust interception capacity) and matching air volume (media surface wind 

speed control).

Improper parameter matching of Aite Dust Removal Air Filter Cartridges leads to on-site failures: excessive surface wind 

speed causes dust penetration and emission exceeding standard; oversized filter cartridge area reduces dust holding

 efficiency and raises procurement costs; insufficient precision leads to early abrasion of exhaust fans and secondary 

environmental pollution.

As a professional manufacturer specializing in industrial dust filtration equipment, we deliver Aite Dust Removal Air Filter 

Cartridges with stable performance, reliable construction, and competitive pricing for industrial facilities worldwide.

2. Filtration Precision Full Parameter System

Aite Dust Removal Air Filter Cartridges are available in four mainstream precision grades – each matched with exclusive

 composite filter media materials:

Precision Grade Particle Size Interception Efficiency Typical Applications

Coarse Efficiency (G1-G2) 20–50μm ≥90% above nominal precision Wood chips, cement aggregate, stone crushing

Medium Efficiency (M3-M5) 5–15μm ≥99% above 10μm; ≥95% at 5μm General machining dust, packaging powder, 

cement grinding

High Efficiency (F6-F8) 1–4μm ≥99.9% at 3μm Pharmaceutical powder, chemical pigment, laser cutting fume, 

welding flue gas

Ultra-High Efficiency (H10-H12) 0.3–1μm ≥99.95% at 0.3μm Battery lithium powder, chemical acid mist, toxic ultrafine dust

Key Media Parameters: PTFE surface membrane composite media achieves efficiency attenuation ≤2% under full dust 

saturation – providing long-term stable emission compliance.

3. Air Volume & Surface Wind Speed Calculation Parameters

Aite Dust Removal Air Filter Cartridges selection follows the basic calculation formula:

S = Q ÷ (v × 60)

Where S = total filter media area (m²); Q = total processing air volume (m³/h); v = allowable media surface wind speed (m/min).

Graded Safe Surface Wind Speed Limits for Aite Dust Removal Air Filter Cartridges:

Dust Concentration & Type Allowable Wind Speed Recommended Precision

Low concentration, medium-coarse dust v = 0.8–1.2 m/min M3-M5 medium precision

Medium concentration, fine industrial dust v = 0.5–0.8 m/min F6-F8 PTFE membrane

High concentration, heavy powder v = 0.3–0.5 m/min High-capacity thickened pleat membrane

Ultra-fine submicron toxic dust v ≤ 0.3 m/min H grade full PTFE membrane

Air Volume Margin Design: Reserve 10% for indoor closed low-dust lines; 20% for semi-open workshop medium dust load; 

30% for outdoor open mining, sandblasting, and kiln high-dust conditions.

4. Working Condition Matching Selection Rules

Cement, Stone Crushing, Aggregate Processing (High Concentration Coarse Dust): Select M3 medium efficiency calendered 

polyester media (10μm); wind speed v = 0.4–0.6 m/min; reserve 30% air volume margin.

Welding, Laser Cutting, Metal Polishing (Medium Concentration Fine Flue Dust): Select F8 grade PTFE surface membrane

 composite media (3μm); wind speed v = 0.5–0.7 m/min; reserve 20% air volume margin; anti-static membrane filter

 cartridge to prevent welding spark static explosion risk.

5. Common Parameter Mismatch Hazards & Troubleshooting

Wind Speed Exceeds Safe Limit: Chimney continuous gray smoke overflow, filter cartridge blockage 2–3 times faster,

 fan power consumption rises sharply. Solution: Add extra rows of filter cartridges to expand total filtration area; 

reduce surface wind speed to standard range.

Precision Grade Lower Than Working Condition Requirement: Fine dust penetrates filter media, exhaust fan impeller

 wears severely, environmental inspection emission exceeds standard. Solution: Replace full set PTFE surface membrane

 high-efficiency filter cartridges; reduce wind speed by 0.1–0.2 m/min as auxiliary optimization.

6. Frequently Asked Questions (FAQ)

Q1: Why can't fine flue dust working conditions use ordinary non-membrane polyester filter cartridges even if wind speed

 is reduced?

A: Ordinary cloth has loose surface fiber structure – submicron fine dust embeds deep into fiber pores, and filtration

 efficiency drops rapidly after short-term ash loading. Aite Dust Removal Air Filter Cartridges with PTFE membrane media

 only retain dust on the film surface to maintain stable high efficiency.

Q2: What is the maximum allowable surface wind speed for sandblasting high-concentration abrasive dust filter cartridges?

A: For Aite Dust Removal Air Filter Cartridges in sandblasting applications, wind speed must be controlled below 0.4 m/min

 with 30% air volume margin reserved – excessive wind speed carries hard abrasive particles that scratch filter media

 and cause permanent leakage holes.

Q3: How to select precision grade for welding fume dust removal?

A: Standard configuration for Aite Dust Removal Air Filter Cartridges in welding fume applications is F8 grade 3μm PTFE 

anti-static membrane filter cartridge – interception efficiency ≥99.9% for welding 3μm metal oxide flue gas, meeting

 national industrial waste gas emission limits.

Q4: What are the four precision grades available for Aite Dust Removal Air Filter Cartridges?

A: Aite Dust Removal Air Filter Cartridges are available in coarse efficiency (20–50μm), medium efficiency (5–15μm), 

high efficiency (1–4μm), and ultra-high efficiency (0.3–1μm) grades.

Q5: How is the total filtration area calculated for Aite Dust Removal Air Filter Cartridges?

A: Total filtration area is calculated using the formula S = Q ÷ (v × 60), where Q is total processing air volume and v is 

allowable media surface wind speed. Aite Dust Removal Air Filter Cartridges selection must reserve appropriate air volume 

margin based on dust load.

Q6: What media material is recommended for high-temperature applications?

A: For high-temperature applications, Aite Dust Removal Air Filter Cartridges use high-temperature aramid media up to 

200°C for cement kiln tail gas and metallurgical high-temperature flue dust removal – precision grade remains stable under 

long-term high temperature.

Q7: What is the efficiency attenuation of PTFE membrane media compared to ordinary polyester?

A: PTFE surface membrane composite media in Aite Dust Removal Air Filter Cartridges achieves efficiency 

attenuation ≤2% under full dust saturation, while ordinary non-film polyester media drops by 15%–25% after 30% dust 

loading.
