High-Performance Synthetic Pocket Filter for Industrial HVAC & Paint Booth Applications

Product Overview

Our synthetic pocket filter is engineered to provide superior particulate capture efficiency in demanding commercial and industrial air handling systems. Constructed from 100% synthetic media, these bag filters offer a lightweight, moisture-resistant alternative to traditional fiberglass or cotton-polyester blends. Designed to fit standard and custom holding frames, the synthetic pocket filter delivers consistent airflow resistance while maximizing dust-holding capacity. Ideal for pre-filtration and final filtration stages in HVAC systems, paint spray booths, and pharmaceutical cleanrooms, this product meets ISO 16890 and EN 779 classification standards.

Key Features

• 100% Synthetic Media – Non-woven polyester fibers resist humidity, mold, and bacterial growth, ensuring long-term performance in damp environments.
• Gradual Density Construction – Coarse fibers on the air-entry side capture large particles, while finer downstream layers trap sub-micron contaminants for progressive loading.
• Thermally Bonded Pockets – No chemical adhesives or binders; pockets are ultrasonically welded to prevent media delamination and off-gassing.
• Low Initial Pressure Drop – Optimized fiber geometry reduces energy consumption by maintaining stable airflow from day one.
• High Dust-Holding Capacity – Deep pocket design (up to 600mm depth) provides up to 40% more surface area than standard bag filters.
• Fire Retardant Option – Available with Class 1 (UL 900) or Euroclass A2 fire rating for compliance with strict safety codes.

Technical Specifications

Application Scenarios

• Commercial HVAC Systems – Office buildings, shopping malls, and hotels where consistent indoor air quality (IAQ) is required without frequent filter changes.
• Paint Spray Booths – The synthetic pocket filter’s low-linting nature and resistance to solvent fumes make it ideal for automotive refinishing and industrial coating lines.
• Pharmaceutical & Cleanrooms – Serves as a pre-filter upstream of HEPA/ULPA filters, extending the life of expensive final-stage filtration.
• Food Processing Facilities – Moisture-resistant media prevents microbial growth in high-humidity environments such as bakeries, dairies, and meat processing plants.
• Data Centers – Low pressure drop reduces fan energy costs while protecting sensitive electronic equipment from airborne particulates.
• General Industrial Ventilation – Cement plants, textile mills, and welding shops benefit from the high dust-holding capacity and easy disposal of synthetic media.

Advantages

• Energy Savings – Compared to rigid panel filters, the synthetic pocket filter’s lower airflow resistance can reduce annual HVAC energy consumption by 10–15%.
• Longer Service Life – Gradual density media allows deep particle loading without surface blinding, typically lasting 2–3 times longer than standard bag filters.
• Eco-Friendly Disposal – 100% synthetic construction is incinerable with minimal ash residue, reducing landfill waste compared to fiberglass alternatives.
• Customizable Configurations – Available with gasketed frames, stainless steel headers for corrosive environments, or integrated pre-filters for multi-stage systems.
• Consistent Efficiency – Electrostatic charging of synthetic fibers enhances capture of fine particles without relying on chemical binders that can degrade over time.

FAQ

Q: What is the difference between a synthetic pocket filter and a fiberglass bag filter?

A: Synthetic pocket filters use polyester or polypropylene fibers that are thermally bonded, making them moisture-resistant, lint-free, and free from fiber shedding. Fiberglass bags can irritate skin and degrade in high humidity, while synthetic media maintains structural integrity even in wet conditions.

Q: How often should I replace a synthetic pocket filter?

A: Replacement intervals depend on the particulate load. In typical commercial HVAC applications, change every 6–12 months. In heavy industrial settings (e.g., cement plants), replace when the pressure drop reaches 400–450 Pa. We recommend using a differential pressure gauge for precise monitoring.

Q: Can the synthetic pocket filter be washed and reused?

A: No. Unlike metal mesh filters, synthetic pocket filters are designed for single-use disposal. Washing damages the fiber structure and reduces filtration efficiency. However, the media is fully incinerable for eco-friendly disposal.

Q: Do you offer custom sizes for non-standard holding frames?

A: Yes. We can produce synthetic pocket filters in any width from 150mm to 1200mm and any height from 150mm to 1000mm. Custom pocket depths (up to 900mm) and odd pocket counts are also available. Please provide your frame dimensions for a quotation.

Q: Is this product suitable for outdoor air intake applications?

A: Yes, especially when paired with a weather hood or pre-filter. The synthetic media is UV-stabilized and resists mold growth, making it suitable for rooftop air handling units in moderate climates. For extreme cold, we recommend a heated housing to prevent ice buildup on the filter media.

Q: What certifications do your synthetic pocket filters have?

A: Our filters comply with EN 779:2012, ISO 16890, and ASHRAE 52.2. Fire-rated versions carry UL 900 Class 1 or EN 13501-1 Euroclass A2 certification. We also provide REACH and RoHS compliance documentation for the European market.
