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 VH Series V-Box High Volume Sub-HEPA Filter is a high-volume, compact filtration product designed for high-cleanliness air conditioning supply systems, cleanroom pre-protection, and special process supply air ducts. It features a V-box dense pleat structure (2V/3V/4V/5V), with standard international dimensions of 610×610×292mm and 305×610×292mm. The frame can be made of galvanized steel, aluminum, or stainless steel. The filter media uses premium ultra-fine glass fiber or polypropylene synthetic fiber, with air pressure adsorption as the core filtration principle. Tested by MPPS laser scanning particle counting, the filtration efficiency covers H10 (85%), H11 (95%), and H12 (99.5%), mainly capturing particles ≥0.3μm. It strictly complies with GB/T 14295-2019 national standard. The product offers high airflow, compact structure, low resistance, and high efficiency. The standard model has a rated airflow up to 3600m³/h, with operating resistance ≤270Pa at rated airflow. To prevent contamination of filtered clean air, it must be installed in the positive pressure section of the air conditioning system. It effectively protects terminal HEPA filters in cleanrooms, significantly extending the service life of high-efficiency filtration equipment. Widely used in electronics, food, pharmaceuticals, hospitals, optics, and other high-standard purification scenarios. Full-size non-standard customization is also supported.

5. FAQ
5.1 Why should V-type sub-HEPA filters be installed in the positive pressure section of air conditioning?
After filtration, the air is extremely clean. Installed in the positive pressure section, it prevents outside dust from contaminating the filtered clean air due to air conditioning system leaks, ensuring supply air cleanliness and protecting downstream HEPA filters.
5.2 How to select among H10/H11/H12 efficiency levels?
Choose H10 for general central air conditioning ventilation; H11 for commercial clean areas and general hospital areas; H12 for high-cleanliness process air supply in electronics, pharmaceuticals, optics, etc.
5.3 What is the replacement cycle for V-type high-volume filters?
Replace every 6-8 months in normal clean environments; every 3-4 months in high-dust, high-cleanliness scenarios; replace immediately when resistance reaches twice the initial resistance.
5.4 Can this product be cleaned and reused?
No. The V-type pleated media structure is precise; washing will deform the media, reduce efficiency, and cause dust leakage. It is a disposable filter, replace directly at end of life.
