With over 20 years of expertise, Chuqi Filtration is a premier source manufacturer of high-performance air filters. Our V-bank HEPA filters (H13/H14) feature an advanced low-resistance design (110 Pa), maximizing energy efficiency and service life.
Operating under ISO 9001:2015, we provide RoHS-compliant and SGS-tested products validated by CNAS laboratories. From custom frames to large-scale OEM production, we deliver reliable, high-capacity purification for semiconductor, pharmaceutical, and commercial HVAC systems worldwide.
Frequently Asked Questions
Q1: Why should I choose a V-bank HEPA filter over a traditional deep-pleat filter?
A: The primary advantage is the High Airflow Capacity. Our V-bank design offers up to 2.5 to 3 times more filtration area than a standard deep-pleat filter. This results in minimal initial resistance (as low as 110 Pa), which significantly reduces energy consumption and extends the filter’s service life by nearly double.
Q2: Are your V-bank filters compliant with international environmental and quality standards?
A: Yes, absolutely. Our filtration materials and components are fully RoHS compliant, ensuring they are free from hazardous substances. Furthermore, our products are rigorously tested by CNAS accredited laboratories and manufactured under an ISO 9001:2015 quality management system to ensure consistent reliability for global export.
Q3: What is the maximum operating temperature and humidity for these filters?
A: For our standard models, the operating temperature is ≤ 80°C (Continuous). The operating humidity can reach ≤ 100% RH (Non-condensing), making them suitable for high-humidity environments like tropical climates or specific industrial processes. If you require a high-temperature version (up to 250°C), please contact us for a customized solution.
Q4: How do you ensure that the filters are leak-proof, especially for H13/H14 grades?
A: We use a dual-component polyurethane sealant that creates a 100% airtight bond between the filter media and the frame (ABS or galvanized steel). Every unit undergoes a strict factory inspection to ensure there is no bypass air, which is critical for semiconductor and pharmaceutical cleanrooms where air purity is non-negotiable.
Q5: Can you provide custom sizes or specific frame materials for my existing AHU?
A: Yes. As a source factory with 20 years of experience, we specialize in OEM/ODM services. While our standard depths are 292mm, we can customize the width and height to fit your specific Air Handling Unit (AHU) or frame housing. We offer frame options in ABS plastic, galvanized steel, and stainless steel to meet different chemical resistance requirements.
