DTAF is your reliable source factory for certified high-efficiency air filtration solutions. Manufactured in our 100,000-class cleanroom, our filters ranging from H10 to U17 deliver exceptional purity and up to 30% energy savings for critical industrial applications.
Off-the-shelf sizes don’t fit every project. As a direct air filter factory, we control the entire production line—from media folding to frame sealing. We provide comprehensive OEM air filter solutions for global HVAC brands, AHU manufacturers, and cleanroom engineering firms.
Explore our comprehensive lineup of primary, medium, and ultra-high efficiency filters designed for heavy-duty industrial and commercial air filtration.
Absolute filtration for cleanrooms, operating theaters, and semiconductor fabs.
Extended surface area offering high dust-holding capacity for HVAC secondary filtration.
Compact V-shaped design for massive air volume with incredibly low pressure drop.
Engineered with silicone-free sealants for ultra-clean drying ovens and auto painting lines.
Premium activated carbon loaded filters to adsorb VOCs, industrial odors, and toxic gases.
Cost-effective primary filtration, including cardboard pleated, washable nylon, and metal mesh.
Heavy-duty industrial filter cartridges for dust collectors, gas turbines, and powder coating lines.
Our engineering team designs specific filtration setups to meet the distinct air quality and regulatory standards of various primary sectors.
From raw rolls to finalized units, we ensure consistency, high-yield capacity, and absolute zero-defect output.
Raw filter media undergoes precise slitting and treatment to match exact frame dimensions.
The filter core is fitted into the outer frame and hermetically sealed using polyurethane resin.
Each unit undergoes rigorous resistance and DOP aerosol testing to verify EN1822 compliance.
Filters are double-bagged inside the cleanroom to prevent any transit contamination.
Palletized securely and dispatched globally from our facility directly to your project site.
We don’t guess; we verify. Every HEPA/ULPA filter exiting our factory is individually performance-tested to guarantee its rated specifications. As a top air filter manufacturer, our in-house testing laboratory strictly follows international protocols.
Ensuring 0% leakage across the entire filter media and frame seals before shipment.
Accurately plotting initial pressure drop vs. airflow to guarantee HVAC energy efficiency and stable performance.
Precision particle counters measuring sub-micron particles (including 0.3μm & 0.1μm) to validate H13-U17 grade efficiency.
Absolutely. We specialize in OEM/ODM production. We can manufacture air filters to your exact dimensional specifications and offer a wide range of frame materials including extruded aluminum, galvanized steel, stainless steel, ABS plastic, and moisture-resistant cardboard.
Yes. Every single HEPA and ULPA filter manufactured in our 100,000-class cleanroom undergoes rigorous individual performance testing (ventilation duct testing) to ensure compliance with EN1822 standards. An independent test report detailing efficiency and initial resistance is included with each high-efficiency filter.
Thanks to our daily production capacity of over 16,500 units, our lead times are highly competitive. For standard products, dispatch takes 3-7 days. For bulk OEM orders requiring custom materials or dimensions, lead times typically range from 7-15 days.
