Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 specializing in high-performance air filtration solutions. Our Polyester flange-clamp air filter, 12x24x2 inch, 150 Pa pressure drop is engineered specifically for pharmaceutical cleanroom make-up air units, where precise contamination control is critical. This filter combines durable polyester media with a robust flange-clamp frame, ensuring a secure seal and easy installation. With over two decades of manufacturing experience and annual exports exceeding US$5 million, we deliver reliable, cost-effective filtration that meets the rigorous demands of sterile environments.
This filter is designed to capture airborne particles, dust, and microorganisms in make-up air systems, maintaining the required cleanliness levels (ISO Class 5-8) for pharmaceutical facilities. The 150 Pa initial pressure drop optimizes energy efficiency while providing consistent airflow. Below, we detail the technical specifications and benefits that make this product a preferred choice for cleanroom operators worldwide.
Key Features & Technical Specifications
- High-Quality Polyester Media: Non-woven polyester fibers provide excellent dust-holding capacity and low resistance. The media is pleated to maximize surface area, enhancing filtration efficiency without increasing pressure drop.
- Flange-Clamp Frame Design: Galvanized steel frame with integral flange clamps ensures a tight, leak-proof fit in standard HVAC systems. No additional tools required for installation – simply clamp into place.
- Precise Dimensions: 12x24x2 inches (nominal size) fits most make-up air unit filter banks. Actual dimensions are 11.5x23.5x1.75 inches for tolerance compatibility.
- Low Initial Pressure Drop at 150 Pa: Optimized for energy savings; lower pressure drop means reduced fan power consumption and longer filter life. This is ideal for continuous operation in cleanroom HVAC systems.
- Pharmaceutical Cleanroom Application: Suitable for pre-filter or secondary filtration in make-up air units supplying ISO Class 5 to Class 8 cleanrooms. Helps comply with GMP (Good Manufacturing Practice) guidelines for air quality.
- Customizable Options: Available in different efficiencies (G3/G4/MERV 8-13), media types (e.g., anti-microbial treated), and frame materials (aluminum or stainless steel) upon request.

Benefits for Your Cleanroom Operation
- Enhanced Air Quality: The polyester media effectively captures particles down to 10 microns (G4) or finer (MERV 8+), reducing contamination risks in pharmaceutical production areas.
- Energy-Efficient Operation: A low initial pressure drop of 150 Pa means your HVAC fans consume less electricity, lowering operational costs over the filter's lifetime.
- Easy Installation & Maintenance: The flange-clamp design allows quick filter replacement without special tools, minimizing downtime. The robust frame resists deformation under continuous airflow.
- Long Service Life: High dust-holding capacity (up to 400 g/m²) extends the filter change interval, reducing waste and labor costs.
- Compliance with Regulatory Standards: While specific certifications are not listed, the filter is designed to meet typical cleanroom guidelines (e.g., EU GMP Annex 1, FDA 21 CFR Part 211). Custom testing can be arranged upon request.

Frequently Asked Questions (FAQ)
Q1: What is the typical efficiency of this polyester filter?
A: The standard version offers G4 / MERV 8 efficiency, suitable for pre-filtration in pharmaceutical cleanrooms. Higher efficiencies (MERV 11-13) are available upon request for more demanding applications.
Q2: Can this filter be used in a high-humidity environment?
A: Yes, polyester media is moisture-resistant, and the galvanized steel frame can withstand moderate humidity. For extremely humid conditions, an optional anti-microbial coating or stainless steel frame is recommended.
Q3: What is the maximum airflow rate for this 12x24x2 filter?
A: The filter is designed for a rated airflow of approximately 500 CFM at 150 Pa pressure drop. Operating at higher airflow may increase pressure drop and reduce efficiency. Consult our technical team for specific applications.
Q4: How often should the filter be replaced?
A: Replacement interval depends on the dust load and operating conditions. Typically, for pharmaceutical cleanroom make-up air, filters are changed every 3-6 months or when pressure drop reaches 250-300 Pa. We recommend monitoring differential pressure.
Q5: Does the filter come with any certification?
A: Our factory follows internal quality standards. Certifications such as ISO 9001 or CE can be provided upon request for specific orders. Please inquire with our sales team for details.
Q6: What is the packaging for export?
A: Filters are packed in individual poly bags, then in sturdy export cartons or pallets. Custom packaging (e.g., neutral boxes, barcode labels) is available upon request.
Q7: Can I get a sample before placing a bulk order?
A: Yes, samples are available. Please contact us with your shipping address and we will provide a quote. Sample cost is deductable from bulk orders.
Q8: What is the lead time for production?
A: For standard 12x24x2 filters, lead time is typically 15-20 days after order confirmation. Custom orders may take 25-30 days. We also offer express delivery for urgent needs.
