Standardized frame dimensions allow direct connection to the filter section interface of various ventilation equipment. Installation requires no complex tools, and one person can easily disassemble and replace the filter. Routine maintenance only involves periodic cleaning or replacement of the filter media, reducing labor and time costs and improving system operation efficiency.
• 2.5 Multiple specifications available, strong customization capabilityFrame thickness offers four standard options: 8, 10, 21, and 46 mm. Common dimensions include 295×295×10/21 mm to 595×595×10/21 mm. Non-standard customization is also supported, allowing adjustments to dimensions based on installation space, airflow requirements, and application scenarios, even customizing multi-layer nylon mesh structures to meet special filtration needs across industries.
• 2.6 Safe and environmentally friendly, compliant with industry standardsThe production process strictly follows the ISO9001 quality control system. The filter media is free of formaldehyde, heavy metals, and other harmful substances, with no odor release during use, ensuring indoor air quality safety. The frame material has a recyclability rate of over 90%, aligning with green environmental protection concepts, and is compatible with various ventilation and purification systems domestically and internationally.

3. Product Applications

3.1 General ventilation and air conditioning systems

Suitable for primary filtration in central air conditioning and centralized ventilation systems of large commercial buildings such as office buildings, conference rooms, hospitals, shopping malls, stadiums, and airports, effectively intercepting airborne ≥5μm large particle dustHair, fibers, and other impurities, preventing subsequent high-efficiency filters from clogging prematurely, extending their service life by over 30%, and reducing overall maintenance costs. It can also be used for primary filtration in household air conditioners and fresh air systems to improve indoor air cleanliness.

3.2 Ventilation filtration in special environments

Designed for special environments requiring acid and alkali resistance, it can be used as ventilation filters in chemical, electroplating, and pharmaceutical industries, as well as air conditioning filter equipment for clean room return air outlets. The corrosion-resistant properties of the nylon mesh ensure stable filtration performance in complex media environments, effectively intercepting large particles in corrosive gases and protecting downstream equipment.

3.3 Pre-filtration for air purification in various industries

As a pre-filtration stage for industries requiring basic air cleanliness, such as electronics, food, pharmaceuticals, hospitals, and aviation, it lays the foundation for subsequent medium and high-efficiency filtration processes. In electronics factories, it prevents dust from contaminating precision components; in food processing plants, it reduces the impact of airborne impurities on product hygiene; in hospitals, it lowers the risk of particle transmission in ventilation systems, fully adapting to diverse industry air purification needs.

4.2 Rated parameters for common specifications

Note: The above are only some common specifications and models. Shenzhen Mingyang Purification Technology Co., Ltd. Custom non-standard nylon mesh filters can be tailored according to the customer's actual installation space, airflow requirements, and application scenarios. Custom products also comply with the GB/T 14295-2019 standard to ensure testing standards and performance. If the ambient temperature and humidity deviate from standard conditions (23°C, 50% RH), the resistance value must be corrected using the formula: Corrected resistance = Measured resistance × (Standard air density / Actual air density), where standard air density is 1.2 kg/m³.

5. FAQ

5.1 How to determine the cleaning method and frequency for nylon mesh filters?

Cleaning method: Use low-pressure clean water (water pressure ≤0.3 MPa) or compressed air (air pressure ≤0.4 MPa) to gently rinse along the fiber direction of the filter media. Avoid reverse rinsing to prevent damage. For stubborn stains, use a neutral detergent. After cleaning, let it air dry naturally (avoid direct sunlight or high-temperature drying) before reinstalling.

Cleaning frequency: For general scenarios, clean every 1-2 months; for industrial environments with high dust concentration, clean every 15-30 days; when the pressure difference across the filter reaches 50 Pa (twice the initial resistance), clean immediately. After 5-8 normal cleanings, if the filter media is damaged, deformed, or filtration efficiency significantly drops (below 50% gravimetric efficiency), replace with a new filter.

5.2 How to select a nylon mesh filter? What key parameters need attention?

Key parameters for selection: ① Airflow matching: Choose a model with rated airflow matching the actual airflow of the ventilation system; it is recommended that actual airflow does not exceed 120% of rated airflow. ② Installation dimensions: Confirm the length, width, and thickness of the installation space, and select standard sizes or custom non-standard sizes. ③ Frame thickness: Choose thickness specifications such as 8, 10, 21, or 46 mm based on installation depth; greater thickness provides more structural stability. ④ Operating environment: For general scenarios, select single-layer or double-layer nylon mesh; for corrosive environments, confirm the corrosion resistance compatibility of the filter media; for high-dust scenarios, multi-layer structures can be customized.

Additionally, considering the protection needs of downstream filtration equipment, the nylon mesh filter serves as primary filtration, mainly intercepting large particles. If downstream equipment requires high-precision filtration, it is recommended to use a higher-efficiency primary filter in combination.

5.3 What specific media environments are suitable for the acid and alkali resistance of nylon mesh filters? What is the service life?

Acid and alkali resistance: Can withstand common weak acids (e.g., acetic acid, citric acid) and weak bases (e.g., sodium hydroxide, sodium carbonate) with a pH range of 4-10. Suitable for ventilation filtration in chemical, electroplating, and pharmaceutical industries. Not recommended for extreme environments with high concentrations of strong acids or bases (pH <4 or pH >10).

Service life: In general civil building ventilation scenarios, with regular cleaning, the service life is 8-12 months; in industrial dust environments, 4-8 months; in corrosive environments, 3-6 months. Service life is closely related to usage frequency and maintenance; proper cleaning and maintenance can effectively extend the service cycle.
