Acrylic Homopolymer Filter Bag

What is an Acrylic Homopolymer Filter Bag?

Acrylic homopolymer filter bags are technical filtration elements developed specifically for use in medium temperature ranges and humid, chemically aggressive environments.

Capable of continuous operation up to 140°C, these bags provide long-lasting and reliable filtration performance in processes with high concentrations of acidic gases and humid dust. Particularly in applications containing high humidity and chemical vapors, they exhibit more stable structure compared to standard polyester bags.

How Does the Production Process Work?

In the production of acrylic homopolymer filter bags, the durability and chemical stability of the fiber structure are prioritized:

Homopolymer acrylic fibers are converted into needle felt.
The bag fabric is made resistant to water and oil through hydrophobic and oleophobic surface treatments.
The calendering (glazing) process applied to the surface prevents dust adhesion and facilitates cleaning.
Finally, the fabric is cut to special dimensions and converted into filter bags using durable sewing machines.

Thanks to these production steps, the bag clogs less in the system, is easy to clean, and maintains filtration efficiency for a long time.

Durability and Technical Compatibility

Acrylic homopolymer filter bags are known for their strong structure against both physical conditions and chemical effects.

Some of their technical features:

Operating temperature: Continuous 130-140°C
Maximum short-term resistance: 150°C
Acid, moisture and hydrolysis resistance: High
Surface properties: Glazed, water and oil repellent
Filtration efficiency: Captures fine dust at high rates
Pressure drop: Low – provides energy savings

Thanks to this technical compatibility, the bag provides both environmentally compliant dust emission and maintains system efficiency.

Use in Chemical Applications

Acrylic filter bags are particularly preferred in humid, acidic and chemical vapor-containing processes. Their application areas include:

Processes containing sulfur gases (SO₂, SO₃)
Flue gas treatment containing acid mists
Lines containing high humidity and temperature combinations
Filter systems working with chemicals

In such processes, the filter bag not only collects dust but also plays a critical role in terms of process safety and facility continuity.

Why Should It Be Preferred?

Acrylic homopolymer filter bags are a good alternative especially for applications where polyester is insufficient. Reasons for preference:

Successfully providing the balance of moisture and chemical resistance
Reducing maintenance and replacement costs with long service life
Contributing to emission control with high dust holding capacity
Low pressure drop providing energy efficiency
Providing optimum performance in medium temperature applications

It is an economically and technically balanced choice for the filtration system.

Main Sectors Where Filter Bags Are Used

Acrylic filter bags are widely used in the following sectors where medium temperature and humid environments coexist:

Fertilizer production and agricultural chemicals
Chemical treatment and processing facilities
Energy and thermal heat recovery systems
Waste gas and flue filter applications
Food industry (lines working in acidic environments)
Metal surface treatment lines

In these sectors, the selection of filter bags is a critical step that directly affects production quality.
