Acrylic Filter Bags

Acrylic Filter Bags Overview

Acrylic filter bags are engineered for industrial dust-collection systems that require strong moisture resistance, stable filtration efficiency, and good chemical durability under medium-temperature operating conditions. Manufactured from high-quality acrylic fibers using a dense needle-punched process, acrylic bags offer a reliable balance of airflow, particle collection, hydrolysis resistance, and structural strength.

They are widely chosen for cement plants, coal mills, boilers, spray dryers, waste incineration systems, asphalt mixing, and general industrial dust processes where temperatures typically remain below 150 °C but gas chemistry or moisture could rapidly degrade polyester or other low-temperature media.

Core Performance Profile

  • Temperature Range: Continuous 120–130 °C; short peaks 140–150 °C
  • Material: 100% acrylic needle-punched felt, with optional scrim reinforcement
  • Chemical Resistance: Excellent tolerance to acids, organic solvents, and corrosive dust
  • Moisture Performance: Strong resistance to hydrolysis and wet flue gas
  • Filtration: Deep-filtration structure for stable airflow and fine particulate capture
  • Applications:
    Cement kilns, boilers, waste incinerators, coal milling, chemical plants,
    asphalt and drying processes

Acrylic filter bags deliver a blend of cost-effectiveness, durability, and operational consistency, making them a popular choice for mid-range industrial conditions where PTFE, PPS, or P84 may not be required.

Key Performance Benefits

01
Reliable Moisture & Hydrolysis Resistance

Acrylic fibers retain their mechanical stability in humid or wet conditions, where polyester bags would suffer accelerated degradation. This makes acrylic an ideal option for systems with water vapor, condensation cycles, or sticky dust.

02
Strong Chemical Resistance

Acrylic felt withstands corrosive exposures such as mineral acids, organic acids, and common industrial solvents, providing stable filtration performance even when flue-gas chemistry fluctuates.

03
Balanced Filtration Efficiency & Airflow

Its needle-punched density creates a deep filtration layer that captures fine dust while maintaining healthy air permeability. This helps sustain lower differential pressure and improves overall system energy efficiency.

04
Excellent Cost-to-Performance Ratio

Acrylic bags offer significantly better chemical and moisture resistance than polyester at a fraction of the cost of PPS, P84, or PTFE, giving plant operators an economical yet reliable mid-temperature solution.

05
Customizable for Diverse Industrial Conditions

Acrylic bags can be engineered with various weights, thicknesses, scrim types, and surface treatments—supporting projects that need enhanced dust release, higher airflow, or extended service life.

Delivering Moisture-Resistant, Medium-Temperature Filtration Through Expertise and Engineered Acrylic Media

130 °C
Moisture-Tolerant Medium-Temperature Window

Acrylic needle-felt runs comfortably around 120–130 °C with short peaks up to about 150 °C, maintaining strength, hydrolysis resistance and stable filtration where humid or mildly acidic flue gas would quickly age standard polyester bags.

≈2×
Extended Life vs Polyester in Humid Service

In cement mills, boilers and spray dryers with moisture and acidic vapours, correctly engineered acrylic bags often achieve up to twice the lifetime of standard polyester media, cutting change-out frequency, labour around the baghouse and unplanned shutdown risk.

INDUSTRIAL
APPLICATIONS

Chemical production, powder processing, and industrial ventilation benefit from acrylic’s strong resistance to acids, solvents, and wet particulates.

Asphalt Mixing, Dryers & Spray Dryers

Asphalt Mixing, Dryers & Spray Dryers

Dust streams with hydrocarbon vapors, organic fumes, and moisture suit the strength profile of acrylic filter media.

Cement & Lime Plants

Cement & Lime Plants

Acrylic media performs exceptionally well in cement mills, kilns, clinker coolers, and raw material handling, where moisture, mild acids, and fine particulate load are common challenges.

Coal-Fired Boilers & Power Generation

Coal-Fired Boilers & Power Generation

In coal milling and boiler exhaust filtration, acrylic ensures stable filtration efficiency despite temperature fluctuations and moderate moisture content.
