The high-efficiency air supply outlet serves as the core terminal component of clean ventilation systems, specifically designed for environments requiring high levels of cleanliness. Equipped with built-in HEPA or ULPA filters, it offers exceptional filtration efficiency for microscopic particulates; when paired with a static pressure plenum and a diffuser plate, it ensures uniform airflow distribution and eliminates airflow dead zones. Featuring a compact structure, versatile installation options, and ease of maintenance, this device is widely utilized in sectors such as pharmaceuticals, electronics, and hospital operating rooms, serving as a critical instrument for maintaining required environmental cleanliness standards.
1. The housing is fabricated from high-quality cold-rolled steel sheet, precision-bent and finished with an electrostatic baked-paint coating.
2. The air diffuser plate is fabricated from high-quality cold-rolled steel sheet; the central area features P5-sized perforations, while the perimeter is uniformly distributed with slotted louvers, all finished with an anti-static baked-paint coating.
3. Side air inlet opening dimensions: W × L (square opening).
4. High-Efficiency Filter dimensions: (W1-50) × (L1-50) × 90.
5. Filter Specifications: Aluminum-frame minipleat HEPA filter. A. Filter Media: Ultrafine glass fiber. B. Frame Construction: High-quality aluminum alloy, joined and formed. C. Filtration Efficiency: H13.
