Product Details
1. Product Introduction
Shenzhen Mingyang Purification Technology Co., Ltd. Specializing in the production of air filters, including primary filters, medium filters, high-efficiency filters, and air conditioning filter screens, widely used in central air conditioning systems, clean rooms, and industrial air purification.
Mingyang's pleated sub-HEPA filter is a core filtration device for clean projects, special air conditioning, and process air supply systems. It covers three standard size series: 610mm international standard, 484mm Chinese classic, and 630mm Chinese exclusive, with full-size non-standard customization supported. The filter uses ultra-fine glass fiber filter paper as the core media, with frames available in galvanized steel, medium-density fiberboard, or aluminum alloy. Separators are either aluminum foil or hard paperboard, and the sealant is polyurethane. Operating temperature range is -20~90°C; aluminum separator models are suitable for humidity ≤99%RH, while paperboard separator models are suitable for humidity ≤85%RH. Filtration efficiency by MPPS method is classified as H10 (85%), H11 (95%), and H12 (99.5%), primarily capturing ultrafine dust particles ≥0.3μm in air, strictly complying with GB/T 14295-2019 national standard. The product features high airflow, low resistance, high dust holding capacity, and robust structure, widely used in clean systems for microelectronics, food, pharmaceuticals, hospitals, optics, and other industries. It is the preferred pleated filter for mid-to-high-end air purification scenarios.
