One-stop HEPA Box solution manufacturer
As a professional manufacturer with a 20,000㎡ modern factory and a 3,500㎡ Class 100,000 cleanroom, SYNRUI not only produces high-efficiency air outlets but also provides comprehensive cleanroom terminal air solutions, from initial design, filter configuration, airflow calibration, installation and positioning to post-installation maintenance.
Many HEPA boxes on the market suffer from problems such as air leakage, poor sealing, uneven airflow leading to substandard local cleanliness, poor fit between the HEPA filter and the housing causing leaks, thin materials, insufficient structural strength making them susceptible to long-term airflow impact, and incompatibility with ceiling systems. SYNRUI's HEPA boxes, through structural reinforcement, upgraded sealing, optimized airflow, and a rigorous testing system, avoid these problems, eliminating the need for rework or repeated adjustments after delivery for buyers.

A HEPA box is a point-of-use air purification and supply device that, through pre-installed HEPA/ULPA filters, evenly delivers clean air into a cleanroom. It is suitable for production environments with stringent cleanliness requirements, such as biopharmaceutical, electronics and semiconductor, food, hospital sterile areas, and laboratories.
Its core functions include filtering particulates and suspended particles, stabilizing airflow, controlling airflow patterns and cleanliness levels, and preventing airflow dead zones and turbulence.
Product Advantages
Leak-free Design: The SYNRUI HEPA Box employs a three-layer sealing structure, including a main sealing strip, high-temperature foam sealing, and a secondary compression structure. Each unit undergoes zero-leakage testing, resulting in 30-50% higher reliability than ordinary products on the market.
High-efficiency and Uniform Airflow: Internal airflow equalization technology ensures an airflow deviation of ≤10%, guaranteeing no localized failure zones within the cleanroom. Compared to traditional HEPA Boxes, airflow uniformity is improved by approximately 25%.
Higher Frame Strength: Constructed with galvanized steel plate/SUS304 stainless steel, combined with a reinforcing rib structure, it will not deform even under long-term exposure to changes in air pressure and temperature/humidity.
Strong Installation Adaptability: Compatible with T-Grid/ceiling systems/keel systems, with optional flange inlet, top interface, and side interface options, adaptable to various engineering installations, significantly reducing construction difficulty.
Quick Filter Replacement: HEPA filters can be replaced without disassembling the entire air outlet, suitable for high-frequency maintenance scenarios in pharmaceutical and laboratory settings.
Supports multiple filter types, HEPA (H13/H14), ULPA (U15–U17)
Mini-pleat / Separator-pleat, adaptable to different cleanliness levels.
OEM/ODM: Airflow, control method, resistance, materials, structural dimensions, and detection port configuration can be customized according to the needs of engineering companies and equipment manufacturers.

FAQ
Q: 1. What is the difference between a HEPA Box and a regular air outlet?
A: A HEPA Box comes with a built-in high-efficiency filter for point-of-use purification; regular air outlets do not have filtration capabilities.
Q: 2. Do you support HEPA Box customization?
A: Customization is supported for dimensions, materials, airflow, interface locations, detection ports, differential pressure gauges, etc.
Q: 3. Which filter grades can the HEPA Box use?
A: H13, H14, U15, and U16 filters can all be used, and can be configured according to the cleanroom's classification.
Q: 4. Is it necessary to disassemble the entire unit to replace the HEPA filter?
A: No disassembly is required; the HEPA filter can be removed directly from the outside for replacement.
Q: 5. Is the airflow uniform? Will there be "air spots"?
A: The internal flow equalization plate + airflow chamber design ensures an airflow velocity deviation of ≤10%, eliminating air spot phenomena.
Q: 6. Is the enclosure prone to air leakage?
A: It adopts a multi-layer sealing structure and undergoes 100% leakage testing, with a leakage rate superior to industry standards.
Q: 7. What types of ceilings can the HEPA Box be installed on?
A: Compatible with various structures including T-bar, joist ceilings, and aluminum profile systems.
Q: 8. Can it be equipped with a differential pressure gauge?
A: Optional monitoring configurations include a differential pressure gauge, anemometer port, and test port.
Q: 9. Can it be used in high humidity or corrosive environments?
A: SUS304/SUS316 materials are available, suitable for high humidity and corrosive environments.
Q: 10. Can you provide on-site installation guidance?
A: Yes, we support on-site technical service, remote video guidance, and complete installation documentation.
