How to Choose Longchen Dust Removal Filter Cartridges?

When selecting dust removal filter elements from Zhongshan Longchen Environmental Protection, please take the following key factors into comprehensive consideration:

Dust Characteristics

1. Particle size: Choose membrane filter media such as PTFE membrane for ultra-fine dust like PM2.5.

2. Humidity: Opt for oil-proof and water-proof treated media including PTFE-coated polyester for high-humidity environments.

3. Temperature: Select glass fiber, PTFE or stainless steel filter elements for working temperatures above 200℃.

4. Flammability: Filters with anti-static design using blended conductive fibers are required for flammable dust.

Filtration Efficiency and Precision

1. For scenarios demanding high precision such as electronics and pharmaceutical industries, use membrane filter media with a filtration accuracy of ≤ 1μm.

2. Polyester or glass fiber media with a filtration rating of 5 - 10μm are suitable for general industrial dust.

Equipment and Working Conditions

1. Pleated filter elements are recommended for limited installation space, while filter bags work better for spacious areas.

2. High-strength media like glass fiber with PTFE coating shall be adopted for systems with pulse jet cleaning.

Material Selection and Cost Budget

1. Economical option: Polyester fiber. It is washable and ideal for ordinary dust applications.

2. Premium option: PTFE coating and stainless steel. These materials feature high temperature resistance, corrosion resistance and long service life.

Installation and Maintenance

1. Match the filter with the interface size of your equipment and inspect the sealing performance.

2. Monitor pressure differential regularly and perform dust cleaning in a timely manner to extend service life.
