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 Foldable Pre-Filter is a high air flow, low resistance, washable primary air filtration product, divided into two main series: MPP type (double-sided galvanized diamond wire mesh folding, economical and practical) and APP type (double-sided φ4.0mm coarse galvanized iron wire mother-and-child frame mesh, structurally robust and impact-resistant). The product uses primary synthetic fiber filter cotton as the filter material, with air pressure adsorption as the filtration principle, achieving filtration efficiency standards of G3 (80%) and G4 (90%) by weight method. It is the preferred solution for primary filtration in central air conditioning, centralized ventilation systems, gas turbines, and industrial inlet air systems, while also supporting custom specifications to fully meet different customer filtration needs.
2. Core product features
- 2.1 Dual Series Structure, Flexible Selection: MPP type features a double-sided galvanized diamond wire mesh folding structure, economical in cost, suitable for budget-sensitive scenarios; APP type uses φ4.0mm coarse galvanized iron wire mother-and-child frame mesh, with a sturdier frame and better impact resistance, suitable for harsh industrial environments.
- 2.2 High Air Volume, Low Resistance, Energy-Saving Operation: The folding structure significantly increases the effective filtration area, allowing for greater air volume and lower initial resistance at the same outer dimensions, significantly reducing system operating energy consumption while balancing filtration efficiency and economic use.
- 2.3 Washable and Reusable, Reducing Operating Costs: The filter material can be cleaned and reused multiple times, with a long service life, effectively reducing the frequency of material replacement and operating costs, especially suitable for long-term maintenance scenarios of large central air conditioning systems.
- 2.4 Wide adaptability and easy installation: Standardized frame dimensions can directly connect to various ventilation equipment, with simple installation and replacement processes that do not require complex construction, reducing labor and time costs.
- 2.5 Customizable, Made to Order: In addition to conventional standard specifications, outer frame thickness, outer dimensions, and filtration efficiency levels can be customized based on the customer's actual installation space, air volume requirements, and usage scenarios, providing personalized matching for various filtration needs.

5. Frequently asked questions
5.1 What is the difference between MPP type and APP type folded initial efficiency filters?
The MPP type features a double-sided galvanized diamond wire mesh folding structure, with a lower outer frame cost, suitable for price-sensitive and relatively mild working conditions (such as central air conditioning in commercial buildings); the APP type uses φ4.0mm coarse galvanized iron wire mother-and-child frame mesh, offering higher frame strength and better impact resistance, suitable for industrial workshops, gas turbines, air compressors, and other environments with significant vibration or harsh working conditions. Both types use the same filter material, and filtration efficiency can be selected as either G3 or G4, allowing for flexible selection based on installation environment and budget.
5.2 Can folded initial efficiency filters be cleaned? Will the efficiency decrease after cleaning?
Washable. Mingyang Foldable Pre-Filter uses washable synthetic fiber filter material, supporting multiple cleanings for reuse. It is recommended to use low-pressure clean water or compressed air to gently rinse along the fiber direction of the filter material, and it can be reinstalled after naturally air drying. After normal cleaning 3 to 5 times, the filtration efficiency remains stable; if visible damage or deformation of the filter material is observed after cleaning, it is recommended to replace it with a new one.
5.3 What industries are suitable for using folded initial efficiency filters?
Applicable to a wide range of scenarios, including: central air conditioning and centralized ventilation systems (commercial buildings, factories, hospitals), gas turbines and air compressors inlet air pre-filtration, household central air conditioning, as well as industries such as electronics, food, pharmaceuticals, aviation, nuclear industry, and defense industry that have basic air cleanliness requirements. G3 efficiency is suitable for general ventilation pre-filtration, while G4 efficiency is suitable for scenarios with slightly higher cleanliness requirements.
