DETAIL

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 WuGe mini-pleat sub-HEPA filters use premium brand ultra-fine glass fiber filter media or high-efficiency low-resistance composite media. Built on a strict quality management system, a Class 10,000 clean production environment, and years of manufacturing expertise, they fully meet high-end purification requirements for clean projects. The filters feature a mini-pleat structure without separators, with an aluminum alloy frame available in four thicknesses: 50mm, 70mm, 80mm, and 90mm. Both the inlet and outlet sides are equipped with double-sided baked enamel protective mesh. Each unit is individually scanned and tested using the MPPS method (European MPPS scanning method / US 0.1-0.2μm scanning method). The MPPS efficiency for laser particle counting corresponds to H10 (85%), H11 (95%), and H12 (99.5%), effectively capturing ultrafine dust particles ≥0.3μm in the air. The products strictly comply with the GB/T 14295-2019 national standard. They feature high airflow, low resistance, high filtration efficiency, and a compact structure, making them widely used in mid-to-high-end purification applications such as microelectronics, food, pharmaceuticals, and hospitals. Non-standard sizes are available upon request.

2. Key Product Features

  • 2.1 Premium filter media, stable performance: Uses ultra-fine glass fiber filter paper or high-efficiency low-resistance composite filter paper, with uniform media distribution, sustained dust capture efficiency, and gradual resistance increase over long-term operation.
  • 2.2 Mini-pleat dense folds, thin and space-saving: Hot melt adhesive evenly separates the filter media, eliminating traditional separators for a thinner profile and larger effective filtration area, suitable for compact installation scenarios.
  • 2.3 MPPS scanning per unit, zero leakage from factory: Each product undergoes MPPS full cross-section scanning testing to prevent air leakage, bypass, and media damage, meeting clean project acceptance standards.
  • 2.4 Double-sided baked enamel protective mesh, durable protection: Both inlet and outlet sides are equipped with double-sided baked enamel protective mesh to prevent media deformation or damage from airflow impact, extending product service life.
  • 2.5 Multiple thickness options, compatible with all equipment: Available in four frame thicknesses: 50mm, 70mm, 80mm, and 90mm, compatible with various purification equipment and installation spaces.

5. FAQ

Why must 5.1 MPPS scanning test be performed on each unit?

MPPS is an internationally stringent testing standard for sub-HEPA filters, allowing full cross-section scanning of filter media efficiency to ensure no leaks and no airflow bypass. It is a mandatory testing requirement for clean project acceptance.

5.2 How to select between 70mm and 90mm thickness products?

Choose 70mm thickness for limited installation space; choose 90mm thickness for larger filtration area, lower operating resistance, and longer service life.

What is the replacement cycle for 5.3 mini-pleat sub-HEPA filters?

Replace every 6-12 months in normal clean environments; every 3-6 months in high-dust workshops or hospital clean areas; replace immediately when resistance reaches twice the initial value.

5.4 How to choose between H10/H11/H12 efficiency levels?

Choose H10 for general central air conditioning ventilation; H11 for shopping malls and general hospital areas; H12 for high-cleanliness scenarios such as electronics, pharmaceuticals, and laboratories.
