Anping County Boli Hardware Wiremesh Products Factory (established in 1998) presents our Washable Pre-filter for Pharmaceutical Cleanroom – a reliable G4 class filter designed to protect sensitive environments from coarse particles. With a compact size of 600x600x50mm, this pre-filter achieves 35% efficiency (G4 class) while maintaining a low pressure drop of 200 Pa and a maximum operating temperature of 70°C. Its low outgassing properties make it ideal for pharmaceutical cleanrooms where air purity is critical. Manufactured with over 20 years of export experience and shipped from major Chinese ports (Tianjin, Qingdao, Shanghai, Foshan), this filter is a cost-effective, washable solution that reduces replacement frequency and operational costs.

Key Features

Washable Design: The filter media can be washed up to 10 times without significant performance loss, extending service life and lowering total cost of ownership.
G4 Class Efficiency: Provides 35% filtration efficiency for particles ≥5 µm, effectively capturing dust, lint, and pollen before they reach main filters.
Low Pressure Drop (200 Pa): Ensures energy-efficient airflow, reducing strain on HVAC systems and saving electricity.
High Temperature Resistance (70°C): Suitable for pre-filtration in warm air streams or near heat sources.
Low Outgassing: Minimal release of volatile organic compounds (VOCs) – critical for pharmaceutical cleanrooms and sensitive manufacturing environments.
Standard Compliant: Meets recognized international standards for cleanroom air filtration (e.g., EN 779, ISO 16890).
Dimensions: 600x600x50 mm – fits standard HVAC frames and cleanroom ceiling grids.

Frequently Asked Questions

Q: How many times can this filter be washed?
A: The filter can be washed up to 10 times under normal conditions. After each wash, allow it to dry completely before reuse. We recommend monitoring pressure drop – if it exceeds 450 Pa after cleaning, replace the filter.
Q: What is the filtration efficiency of this G4 pre-filter?
A: It achieves 35% efficiency for particles of 5 µm and larger (G4 class per EN 779). This is ideal for capturing coarse dust, lint, and pollen, protecting downstream HEPA filters.
Q: Is this filter suitable for high-temperature environments?
A: Yes, it can operate continuously at temperatures up to 70°C. For higher temperatures, please contact us for custom solutions.
Q: Does the filter have any certifications?
A: Our filters are manufactured in compliance with international standards (EN 779, ISO 16890). Specific certifications can be discussed upon request; we do not claim unverified certification.
Q: What is the recommended cleaning method?
A: Rinse with clean water or mild detergent (non-abrasive). Do not use high-pressure washers that may damage the media. Air dry or use low heat (
Q: Can I get custom sizes or frame materials?
A: Yes, we offer customization options including frame material (aluminum, galvanized steel, plastic) and dimensions. Minimum order quantity may apply.
Q: How long does shipping take?
A: We ship from Tianjin, Qingdao, Shanghai, or Foshan ports. Typical lead time is 15–25 days for standard orders, depending on quantity and destination.
Q: What is the pressure drop after washing?
A: The initial pressure drop after washing may increase slightly (by 10–20%) due to residual moisture or slight media deformation. Once dry, it returns close to the original 200 Pa value.
