Rigid Reliability at High Airflow: Box-Type High-Volume Air Filters

The Box-Type High-Volume Air Filter delivers dependable high-airflow filtration in a rigid box housing — a robust, space-efficient structure that withstands the rigors of continuous cleanroom and HVAC service. The deep-pleat media inside the box provides a large filtration area, achieving H13-H14 high efficiency at low resistance, while the rigid box construction ensures dimensional stability, leak-free sealing, and long service life. The reliable high-volume filtration choice for cleanroom fresh air systems, FFU units, and air handling units.

Rigid Box Housing — Durable & Stable
The filter media is housed in a rigid box structure — providing dimensional stability, structural strength, and reliable sealing that withstands continuous service.
Deep-Pleat Media — Large Filtration Area
The deep-pleat (mini-pleat) media configuration packs a large filtration area into the box — delivering high airflow capacity with dependable filtration performance.
High-Efficiency Filtration (H13-H14)
Achieves H13-H14 high-efficiency filtration (EN 1822) — capturing sub-micron particles for cleanroom-grade air purity.
High Airflow with Low Resistance
The large media surface area delivers high airflow at low pressure drop — reducing fan energy consumption.
Leak-Free Sealed Construction
The media pack is sealed within the rigid box with PU (polyurethane) or equivalent sealing — preventing bypass leakage around the media.
Compact & Space-Efficient
The box configuration provides high filtration capacity in a compact, stackable footprint — efficient for cleanroom ceiling and mechanical room installations.
Wide Application
Suited to cleanroom fresh air systems, FFU units, AHU final stages, and high-airflow pharmaceutical and electronics facilities.
