Shenzhen Mingyang Purification Technology Co., Ltd. was established in 2008 and is a professional enterprise integrating the research and development, design, manufacturing, installation, and after-sales of air filters and purification equipment. With seventeen years of manufacturing experience, the company has passed ISO9001 quality certification and ISO14001 environmental certification, covering numerous fields including electronics, food, pharmaceuticals, hospitals, and aviation, dedicated to providing customers with high-quality air purification solutions.
Mingyang nylon mesh filter is a core product for primary air filtration with high air volume, low resistance, and repeatable cleaning, specifically designed for the pre-filtration stage of various ventilation systems. The product consists of an aluminum alloy frame and polyamide nylon mesh, with internal support made of iron wire or flat steel welding. The filter material is black nylon mesh, exhibiting excellent acid and alkali resistance and corrosion resistance, can be repeatedly cleaned without affecting filtration efficiency, and is conventionally designed as a double-layer nylon mesh, with multi-layer structures customizable based on demand.
This product mainly filters dust particles ≥5μm in the air, with a weight-based filtration efficiency reaching G2 level (60% weight-based), and an initial resistance of only 25Pa, complying with the GB/T 14295-2019 standard for air filters. It is the preferred solution for primary filtration in central air conditioning, household air conditioning, and various large building ventilation systems. It also supports non-standard specification customization, allowing adjustments to the shape and frame thickness based on customer actual installation space and air volume requirements, fully meeting personalized filtration needs in different scenarios.

Note: The above are only some commonly used specifications and models. Shenzhen Mingyang Purification Technology Co., Ltd. can customize various non-standard nylon mesh filters according to the actual installation space, air volume requirements, and usage scenarios of customers. Customized products also adhere to the GB/T 14295-2019 standard, ensuring testing standards and performance. If the environmental temperature and humidity deviate from standard conditions (23°C, 50% RH), the resistance value needs to be corrected according to the formula: corrected resistance = measured resistance × (standard air density / actual air density), with standard air density being 1.2kg/m³.
5. Frequently asked questions
5.1 How to determine the cleaning method and frequency for the nylon mesh filter?
Cleaning method: It is recommended to use low-pressure clean water (water pressure ≤0.3MPa) or compressed air (air pressure ≤0.4MPa) to gently rinse along the fiber direction of the filter material, avoiding reverse washing that could damage the filter material. During cleaning, neutral detergents can be used to remove stubborn stains, and after cleaning, it should be air-dried naturally (avoiding exposure to direct sunlight or high-temperature drying), and the filter material should be completely dry before reinstalling for use.
Cleaning frequency: It is generally recommended to clean once every 1-2 months in ordinary scenarios; in industrial environments with high dust concentration, it is recommended to clean once every 15-30 days; when the pressure difference before and after the filter reaches 50Pa (twice the initial resistance), immediate cleaning is required. After normal cleaning 5-8 times, if the filter material is found to be damaged, deformed, or the filtration efficiency significantly decreases (below 50% weight-based), it is recommended to replace it with a new one.
5.2 How to select a nylon mesh filter? What key parameters should be noted?
When selecting models, pay special attention to the following parameters: ① Air volume matching: Choose the model with the corresponding rated air volume based on the actual air volume of the ventilation system, it is recommended that the actual air volume does not exceed 120% of the rated air volume; ② Installation dimensions: Confirm the length, width, and thickness dimensions of the installation space, and choose the appropriate standard specifications or customize non-standard sizes; ③ Frame thickness: Choose thickness specifications of 8, 10, 21, 46mm based on installation depth, the thicker the frame, the more stable the structure; ④ Operating environment: For ordinary scenarios, choose single-layer/double-layer nylon mesh, for corrosive environments, confirm the compatibility of filter materials with corrosion resistance, and for high dust scenarios, multi-layer structures can be customized.
In addition, considering the protection requirements of subsequent filtration equipment, the nylon mesh filter serves as a primary filter, mainly intercepting large particle impurities. If the subsequent equipment is high-precision filtration, it is recommended to use a more efficient pre-filter in conjunction.
5.3 What specific media environments are suitable for the acid and alkali resistance performance of the nylon mesh filter? How long is its service life?
Acid and alkali resistance: It can withstand common weak acids (such as acetic acid, citric acid) and weak bases (such as sodium hydroxide, sodium carbonate), with a pH range suitable for 4-10, applicable for ventilation filtration in industries such as chemicals, electroplating, and pharmaceuticals, but it is not recommended for use in extreme environments with high concentrations of strong acids or strong bases (pH <4 or pH >10).
Service life: In ordinary civil building ventilation scenarios, with normal maintenance (regular cleaning), the service life can reach 8-12 months; in industrial dust environments, the service life is 4-8 months; in corrosive environments, the service life is 3-6 months. The service life is also closely related to usage frequency and maintenance conditions, and standardized cleaning and maintenance can effectively extend the usage cycle.
