Product Details
1. Product Introduction
Shenzhen Mingyang Purification Technology Co., Ltd. specializes in the production of air filters, pre-filters, medium-efficiency filters, high-efficiency filters, and air conditioning filter nets, with products widely used in central air conditioning systems, clean rooms, and industrial air purification fields.
Mingyang VH series V-type high air volume sub-high efficiency filter is specially designed for high cleanliness air conditioning supply systems, clean room pre-protection, and special process air duct applications. It features a V-shaped box structure with compact pleats (2V/3V/4V/5V), standard sizes of 610×610×292mm and 305×610×292mm, with frame options of galvanized steel, aluminum, or stainless steel. The filter media is made of high-quality ultra-fine glass fiber or polypropylene fiber, utilizing air pressure adsorption as the core filtration principle. The filtration efficiency is tested using the MPPS laser scanning method, covering H10 (85%), H11 (95%), and H12 (99.5%) levels, primarily capturing ultra-fine dust particles ≥0.3μm, strictly adhering to the GB/T 14295-2019 national standard. The product boasts core advantages of high air volume, compact structure, low resistance, and high efficiency, with a standard model rated air volume of up to 3600m³/h and operating resistance ≤270Pa. To prevent contamination of the clean air after filtration, it should be installed in the positive pressure section of the air conditioning system, effectively protecting the high-efficiency filter at the clean room's end and significantly extending the service life of high-efficiency filtration equipment. It is widely applicable in high-standard purification scenarios such as electronics, food, pharmaceuticals, hospitals, and optics, and supports full-size non-standard customization.
2. Core product features
- 2.1 High air volume compact design, high space utilization: The V-shaped box structure has a thickness of only 292mm, with a rated air volume of up to 3600m³/h for the standard 610×610mm model, achieving ultra-high ventilation volume within limited installation space, suitable for central air conditioning and duct supply systems.
- 2.2 Ultra-high filtration efficiency, MPPS precise detection: High-quality glass fiber/polyester filter media are used to maximize effective filter area, achieving MPPS method efficiency of H10/H11/H12, with a high interception rate for ultra-fine dust particles ≥0.3μm, ensuring stable clean purification effects.
- 2.3 Ultra-low operating resistance, significant energy savings: The pleated filter media layout ensures smooth airflow, with resistance not exceeding 270Pa at rated air volume, significantly reducing the load on ventilation system fans and achieving outstanding energy-saving effects during long-term operation.
- 2.4 Multiple material frame options available, suitable for all working conditions: The frame offers three choices: galvanized steel, aluminum, and stainless steel, which are corrosion-resistant and high-strength, suitable for various industrial and purification working conditions including regular, humid, and corrosive environments.
- 2.5 Designed for installation in the positive pressure section, preventing secondary pollution: Specifically designed for the positive pressure section of air conditioning systems, it prevents leakage and contamination of already filtered clean air, ensuring the cleanliness of the supplied air and perfectly protecting the downstream high-efficiency filter.

5. Frequently asked questions
5.1 Why should the V-shaped sub-high efficiency filter be installed in the positive pressure section of the air conditioning system?
The air cleanliness after filtration is extremely high, and installation in the positive pressure section can prevent external dust contamination of the already filtered clean air, ensuring the cleanliness of the supplied air and protecting the downstream high-efficiency filter.
5.2 How to choose among the three efficiency levels H10/H11/H12?
For conventional central air conditioning ventilation, choose H10; for commercial clean areas and general hospital areas, choose H11; for high cleanliness processes in electronics, pharmaceuticals, optics, etc., choose H12.
5.3 What is the replacement cycle for the V-shaped high air volume filter?
For conventional clean environments, replace once every 6-8 months; for high dust and high cleanliness scenarios, replace once every 3-4 months; replace immediately when the resistance reaches twice the initial resistance.
5.4 Can this product be cleaned and reused?
No. The V-shaped pleated filter media structure is precise, and washing it can cause deformation, reduced efficiency, and dust leakage. It is a disposable filter that should be replaced directly when it reaches its service life.
