HEPA Air Filter Box for Duct Systems/Cleanrooms

Tianjia Dedicated HEPA Air Filter Box for Duct Systems: Creating Efficient Clean Barrier for Ventilation Pipe Networks

I. Core Technical Highlights

1. Duct Integrated Design, Seamless Adaptation to Ventilation Pipe Networks

    

   Tianjia dedicated HEPA air filter box for duct systems adopts an integrated structure of aluminum frame + polyurethane sealant, directly embedded into industrial ducts and cleanroom ventilation systems for seamless docking with air ducts to avoid air leakage risks. Installation efficiency is improved by 40% compared with independent filters, adapting to renovation and new‑build projects of various duct systems.
    
2. H13/H14 High‑Efficiency Filtration, Ultimate Interception of 0.3μm Particles

    

   The fiberglass media of Tianjia dedicated HEPA air filter box for duct systems has interception efficiency >99.995% for 0.3μm particles, efficiently capturing dust, oil fumes, microbes and other pollutants in ducts. It ensures air cleanliness at terminal air outlets meets advanced ISO standards, providing reliable protection for ventilation systems in pharmaceutical, electronics and other industries.
    
3. Low Resistance & High Airflow Design, Adapting to Duct Ventilation Efficiency

    

   The optimized labyrinthine fiber structure of Tianjia dedicated HEPA air filter box for duct systems expands filtration area, keeping wind resistance within a reasonable range while ensuring high filtration efficiency. It handles high‑airflow ventilation, adapting to 24/7 continuous duct ventilation in industry and reducing HVAC energy consumption.
    
4. Industrial‑Grade Durable Materials, Stable Operation in Complex Duct Environments

    

   The aluminum frame of Tianjia dedicated HEPA air filter box for duct systems is resistant to high temperature (80°C), high humidity (80%RH) and chemical corrosion, operating stably long‑term in complex environments such as coating workshops and chemical ducts. Service life is more than twice that of ordinary duct filters, reducing maintenance costs of frequent replacement.
    
5. Modular Quick Replacement, More Efficient Duct Operation & Maintenance

    

   Tianjia dedicated HEPA air filter box for duct systems adopts a drawer‑type modular design, enabling quick filter replacement without shutting down the duct system. Paired with silicone gel installation sealing material, it ensures no leakage after replacement, adapting to continuous industrial production scenarios and avoiding production interruption caused by filter replacement.

III. Installation Process

1. Check dimensions, specifications and sealing accessories against duct system drawings after receiving the filter box; install only after confirming no damage.
2. Apply silicone gel sealing material at the reserved installation position in the duct, embed and fix the filter box to ensure seamless fit.
3. Perform leak detection after installation; start ventilation system after confirming no leakage, test airflow resistance and filtration efficiency.
4. Record initial operating parameters, conduct regular differential pressure monitoring. When differential pressure exceeds twice the initial value, replace the filter element.

IV. Daily Usage Precautions

1. Monitor pressure difference before and after the filter box monthly; check for filter clogging or seal leakage if pressure rises abnormally.
2. Replace filter element every 6–12 months (adjust according to usage scenario); wear dust masks and gloves during replacement to avoid dust contamination.
3. Store spare filter boxes in dry, dust‑free industrial warehouse, away from chemicals to prevent frame oxidation and filter media moisture.
4. Perform leak detection after filter replacement to ensure sealing performance meets standards; do not stack heavy objects near the filter box to prevent frame deformation.
