Stainless Steel HEPA BOX
The Stainless Steel High-Efficiency Air Supply Outlet serves as the core terminal equipment in cleanroom air purification systems. Through high-efficiency filtration and directional airflow design, it uniformly distributes purified clean air throughout the interior while isolating external contaminants. This ensures overall cleanroom cleanliness compliance, making it widely applicable in pharmaceutical, electronics, biotechnology, medical, and other fields with stringent air quality requirements.
What is a High-Efficiency Air Outlet?
High-efficiency air diffusers, commonly referred to as “HEPA Boxes” or “Supply Air Ceilings,” are among the most critical components of cleanroom HVAC systems. Positioned at the terminal end of the supply air system, they serve as the final point where air enters the cleanroom.
Looking for a reliable HEPA filter housing box for your cleanroom project? As a professional cleanroom equipment factory, we provide high-quality terminal HEPA boxes designed for pharmaceutical, laboratory, and industrial applications.
Whether you need a pharmaceutical HEPA diffuser or a laboratory HEPA housing, our products ensure a leak-proof, sterile environment that meets the strictest ISO 14644 standards.

Why Choose Stainless Steel?
Among the various materials used for high-efficiency air diffusers, stainless steel (commonly grades such as 304 or 316) stands out due to its exceptional properties:
- Strong Corrosion Resistance: Resists damage from disinfectants, chemical solvents, and humid environments, making it particularly suitable for pharmaceutical and biological laboratories requiring frequent cleaning and disinfection.
- High Cleanliness: Features a smooth surface that resists dust accumulation and facilitates easy cleaning, meeting stringent material requirements such as GMP (Good Manufacturing Practice).
- Strength and Durability: Constructed with robust materials for extended service life.
