Deep Pleated HEPA Filter

The deep pleated HEPA filter is a high-efficiency air filter designed specifically for high-cleanliness environments. Its corrugated aluminum foil partition design divides the filter media into numerous narrow channels, causing the airflow within the filter to follow an arc-shaped path. This increases the contact opportunities between particulate matter and the filter media, enabling the capture of dust particles larger than 0.3 μm with a filtration efficiency reaching over 99.995%.

Filtration Grade: E10、E11、E12、H13, H14 (EN1822)
Separators: double corrugated cardboard or aluminum foil corrugated
Frame: aluminum alloy / galvanized iron / stainless steel / wooden frame
Temperature Resistance: ≤90 ℃
Moisture Resistance: ≤100%RH
Filtration Object: ≥ 0.3 μm or ≥ 5 μm particles
