HEPA Terminal Filter Housing Box China Factory
The hepa filter box serves as an indispensable terminal filtration device for Class 1000, Class 10000, and Class 100000 cleanroom purification air conditioning systems. It is widely implemented across global high-tech industries, including biopharmaceuticals, medical care, healthcare laboratories, microelectronics manufacturing, and fine chemical processing.
As a critical air supply component, the hepa filter terminal box is heavily utilized in both the new construction and high-grade renovation of cleanrooms ranging from Class 1000 to Class 300000. It acts as the ultimate defense line to meet rigorous airborne particulate control requirements. Structurally, each comprehensive hepa filter housing box assembly is engineered with a premium air plenum chamber, an efficient air diffuser plate, a high-efficiency mini-pleat HEPA filter, and an adaptable duct connection inlet that supports both top-entry and side-entry configurations.
Our specialized hepa filter box series is categorized into two distinctive technical designs to accommodate various cleanroom ceiling spaces and operational preferences:
Series I (Replaceable Filter Type): This configuration consists of a permanent terminal hepa filter housing body combined with a replaceable filter cartridge and an aluminum alloy diffuser plate. It is exceptionally easy to install, ensures a reliable airtight seal, and allows maintenance personnel to replace the internal filter directly from inside the cleanroom without disrupting the ceiling structure.
Series II (Disposable/Integrated Type): Available in ultra-thin and standard thin designs, this integrated hepa terminal box operates as a single, fully sealed unit. When the filter reaches its lifespan, the entire housing is replaced simply by removing the tube hoop or soft joint connection between the duct air supply pipe and the inlet collar. This series is particularly ideal for cleanroom ventilation systems with highly restricted or narrow ceiling spaces.

Every hepa filter housing box manufactured by our facility delivers outstanding technical stability and long-term durability through the following characteristics:
Premium Housing Material: The main casing of the terminal hepa filter housing is fabricated from high-quality cold-rolled steel plates, precisely bent, welded, and treated with an anti-static electrostatic baked paint spray to prevent corrosion and surface shedding.
Aesthetic and Compact Layout: Features a compact structure that is highly compatible with modular cleanroom sandwich panels, minimizing installation space while delivering uniform air distribution.
Advanced Air Diffusion Panels: The air outlet diffuser panel can be customized using aluminum spray coating, cold-rolled steel spray, or premium stainless steel. The central diffusion zone features optimized $5\text{ mm}$ perforations accompanied by evenly distributed louver-type slots to ensure gentle, stable, and down-supply air currents.
Reliable Filter Clamping Components: Outfitted with robust plastic filter press blocks and M8 hexagon bolts to provide strong, even pressure onto the aluminum frame mini-pleat HEPA filter, preventing any bypass leakage.
