The Industrial Grade Air Filtration HEPA Box is a high-performance terminal air filtration device designed for industrial clean room construction and renovation, engineered to deliver consistent, high-efficiency particulate removal for factory production lines. As a core component of clean room HVAC systems, this HEPA box features a cold-rolled steel shell with electrostatic spray coating, integrating a static pressure tank, high-efficiency HEPA filter, and diffuser plate in a compact structure. It is installed as a terminal HEPA filter in clean room ceilings, providing a cost-effective clean air solution with low investment and simple construction—key advantages for factory buyers in electronics, pharmaceuticals, and food processing. The DOP liquid tank type design optimizes air pressure distribution, ensuring the HEPA filter operates at an ideal static pressure for maximum filtration efficiency and service life. With 99.99% filtration efficiency for 0.3μm particles and a full range of models for different air flow requirements, this Clean Room Terminal HEPA Filter Box is the ideal choice for new clean room construction and old factory clean area renovation, meeting ISO 14644 and industrial clean production standards.
Durable Cold-Rolled Steel Construction: Electrostatic spray coating on the shell for anti-corrosion and scratch resistance, suitable for harsh industrial factory environments.
DOP Liquid Tank High-Efficiency Air Supply: Optimizes static pressure for the HEPA filter, ensuring uniform airflow and avoiding filter damage from unstable pressure.
Integrated Static Pressure Tank & Diffuser Plate: Eliminates turbulent air, delivers laminar flow to the production area, and ensures consistent cleanliness across the entire work zone.
Professional Differential Pressure Detection: Reserved ports for differential pressure gauges to monitor filter clogging status and facilitate timely replacement.
Strong Ventilation Performance: High air flow capacity with low resistance, suitable for large-area industrial clean room air supply systems.
Easy Installation & Maintenance: Modular design for quick ceiling mounting; filter replacement without disassembly of the main body, saving factory downtime.
Diverse Accessory Configuration: Optional air valves, powder swirl diffusion panels, and flow meters to adapt to different factory process air supply needs.

Ceiling Installation Position Reservation: According to the clean room layout, reserve installation holes in the ceiling grid; ensure the spacing meets the air supply coverage requirements of the production line.
Main Body Fixation: Hoist the HEPA box to the reserved ceiling position using heavy-duty hangers; reinforce the structure to bear the weight of the device and avoid shaking during operation.
HEPA Filter Installation: Place the filter into the DOP liquid tank, ensure airtight sealing with the tank’s sealant, and lock the filter cover to prevent air leakage at the joint.
Air Duct Connection: Connect the top/side wind tube to the factory’s central air supply duct; use sealing tape for all joints to eliminate air leakage and ensure static pressure stability.
Diffuser Plate Mounting: Fix the diffuser plate to the air outlet of the HEPA box; adjust the installation angle to ensure uniform airflow distribution to the production area.
Commissioning & DOP Testing: Power on the central air supply system; test air flow and uniformity, and perform DOP testing to verify the filtration efficiency of the entire unit.
Acceptance & Sign-off: Record the initial differential pressure and air flow data; affix a factory equipment label with model, installation date and maintenance cycle.
Electronics & Semiconductor Factories: Clean room air supply for wafer fabrication, chip assembly and microelectronic component production, meeting ISO Class 5-7 standards.
Pharmaceutical Production Workshops: Terminal air filtration for drug production, filling and packaging lines, compliant with GMP clean room requirements.
Food Processing Clean Zones: Air supply for high-end food, dairy and beverage production to prevent microbial and dust contamination, meeting HACCP standards.
Medical Device Manufacturing Factories: Clean air supply for the production of sterile medical devices such as surgical instruments and implantable devices.
Automotive Precision Parts Factories: Filtration for the production of automotive electronic components and precision mechanical parts sensitive to particulate contamination.
Cosmetics Production Lines: Terminal air filtration for clean production of high-end cosmetics and skincare products, ensuring product sterility.
Industrial Lab Renovation: Air supply upgrade for factory R&D labs to convert ordinary labs into clean work zones for precision testing.
Material Customization: SUS304/SUS316 stainless steel shell for high-hygiene industrial environments such as pharmaceutical and food factories.
Filter Size Customization: Non-standard HEPA filter dimensions to adapt to the factory’s existing air supply duct and ceiling layout.
Air Duct Interface Customization: Custom top/side wind tube sizes and shapes for seamless connection with the factory’s original HVAC system.
Accessory Customization: Integrate differential pressure gauges, air volume control valves, and powder swirl diffusion panels for specific process needs.
Air Flow Customization: Custom rated air flow to match the air supply requirements of large-area industrial clean rooms or small-scale clean zones.
Spray Color Customization: Custom electrostatic spray colors to match the factory’s clean room decoration style and corporate image.
Yes, it is specially designed for both new clean room construction and old factory clean area renovation, with simple installation and no need for large-scale HVAC system reconstruction—saving time and cost for factories.
Under 24/7 industrial use, the filter replacement cycle is 8-12 months; replacement is required when the differential pressure exceeds 400pa (monitored via the differential pressure gauge).
The standard model is designed for ceiling mounting; wall-mounted or floor-standing models can be customized according to factory space constraints and air supply needs.
The electrostatic spray coating provides basic anti-corrosion protection; for high-humidity environments (e.g., food processing), a stainless steel shell is recommended for customization.
Select the model based on two key parameters: the rated air flow of the clean room per unit area and the size of the existing air supply duct; our technical team can provide free on-site measurement and model selection.
