    Product Details

    Application Area

    Ordinary automotive repair paint shops, industrial spraying, etc., are currently the most widely used types.

    Main Characteristics
    • Excellent Flame Retarding: Glass fiber itself is non-combustible, meeting fire safety requirements for paint spray booths.
    • High Filtration Efficiency: Particularly effective at capturing large and medium-sized paint mist particles.
    • Low Cost: Economical and cost-effective, making it a mainstream choice in the market.
    The Efficiency of Coarse Filter Cotton

    The efficiency of currently available ranges from 40% — they can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.

    Service Life of Filters

    As dust accumulates on the filter media, the resistance increases. When the resistance reaches an unreasonable level, the filter must be discarded. Sometimes, excessive resistance can cause previously captured dust to become dislodged and re-enter the airflow; when this risk arises, the filter should also be replaced. The resistance of a filter increases with higher airflow rates. By increasing the surface area of the filter media, the relative velocity of air passing through the filter can be reduced, thereby decreasing the resistance.

    Frequently Asked Questions
    Q What are the main application areas of coarse filter cotton?
    Coarse filter cotton is most widely used in ordinary automotive repair paint shops and industrial spraying environments. Its cost-effectiveness and reliable filtration performance make it the mainstream choice across these industries.
    Q Is coarse filter cotton fire-safe for use in spray booths?
    Yes. Coarse filter cotton is typically made from glass fiber, which is non-combustible. This excellent flame-retarding property ensures it meets the fire safety requirements commonly mandated for paint spray booth environments.
    Q What filtration efficiency can I expect from coarse filter cotton?
    The filtration efficiency of currently available coarse filter cotton starts from around 40%. Different grades can be selected based on your specific application requirements. Choosing the right filter efficiency combined with an appropriate face velocity helps maximize overall economic benefits.
    Q How do I know when it is time to replace the filter?
    As dust accumulates, the filter's resistance (pressure drop) increases. Once resistance reaches an unreasonable or excessive level, the filter should be replaced. Additionally, if the high resistance risk causing captured dust particles to be dislodged and re-enter the airflow, immediate replacement is recommended to maintain air quality.
    Q How can I extend the service life of my filter?
    You can extend filter service life by selecting a filter with a larger surface area of filter media. A larger surface area reduces the relative air velocity passing through the filter, which lowers resistance and slows dust accumulation — resulting in longer operational life and better overall performance.
    Q Why is coarse filter cotton considered a cost-effective solution?
    Coarse filter cotton offers a strong balance between performance and price. Its high filtration efficiency for large and medium-sized paint mist particles, combined with low material cost and easy availability, makes it an economical and practical choice — which is why it remains the dominant filter media in the market.
