The One-Stop Clean Air Solution Manufacturer
With over 30 years of industry dedication, DTAF engineers world-class air filtration products. Exporting to over 100 countries across Europe, the Americas, Southeast Asia, and Africa.
Massive Scale & Medical-Grade Precision
Located in Qingyuan, Guangdong, our 11,600 ㎡ manufacturing facility is engineered for high-yield, zero-defect production. From cleanroom assembly to secure export logistics, we control the entire vertical.
Guaranteed massive output for global wholesale distributors.
Absolute dust-free environment essential for HEPA integrity.
We eliminate sea freight risks. By owning our wood, plastic, and corrugated packaging production lines, we custom-build heavy-duty crates that guarantee zero deformation of sensitive filters and large equipment upon arrival.
Independent Lab & 3-Step TQM Protocol
DTAF operates South China’s high-standard Air Filtration Testing Laboratory, rivaling third-party institutional levels. We don’t guess; we test.
Incoming Quality Control
Beyond visual and dimensional checks, raw media undergoes stringent parameter testing (e.g., TSI permeability) before entering the cleanroom.
In-Process Quality Control
Mandatory routing inspections. Every assembly station acts as a checkpoint, requiring verification of the previous step’s compliance.
Outgoing Quality Control
First-piece and 100% full inspection on filtration efficiency, initial resistance, diagonal dimensions, and appearance.
