The Thesvin V-Bank High Efficiency Filter is a V-cell air filter that removes fine particulate from high-flow ventilation and clean air systems, with efficiency grades from M6 to H14. It is built for engineers and facility teams who need dependable fitment in AHUs, FFUs, and MAU systems where space and airflow are fixed. Thesvin manufactures this filter with a rigid frame and glass fibre media to deliver low resistance and stable sealing in demanding installations.
Fitment is the first consideration in any V-bank filter installation. Thesvin offers two frame options—ABS high-strength plastic and galvanized iron—both designed to hold the V-shaped media pack square and true under 2.5 m/s rated airflow. The V-bank geometry increases media area within a compact depth, so the filter can be accommodated in standard holding frames without altering ductwork. The rigid frame resists deflection at high velocity, helping maintain a uniform seal against the frame gasket and preventing bypass.
Because dimensions are critical, Thesvin supplies common face sizes with a 292 mm depth: 24×24×12 inches (592×592×292 mm), 20×24×12 inches (490×592×292 mm), and 12×24×12 inches (287×592×292 mm). These are nominal sizes; actual dimensions are held to tight tolerances to match standard filter grids. For non-standard openings, Thesvin supports full OEM customisation of size, frame material, and V-bank count, so the filter can be specified to your exact interface drawing. The goal is a drop-in fit that seals correctly and requires no adapter.
Thesvin V-Bank filters use high-quality ultra-fine glass fibre paper as the core media. This media is pleated into V-shaped packs to create a large filtration surface in a small footprint. The filter is rated for particulate removal from M6 through H14, covering medium-efficiency pre-filtration up to HEPA-grade final filtration. At H13 and H14, the filter achieves removal efficiencies of ≥99.95% and ≥99.995% for 0.3 μm particles, respectively. The V-bank design keeps initial resistance low—typically ≤250 Pa—which reduces fan energy while maintaining airflow.
Typical applications include pharmaceutical GMP cleanrooms, semiconductor fab cleanrooms, hospital operating rooms, gas turbine intake systems, and central air handling units in commercial buildings. The filter is also suited to AI data centre cooling systems and energy storage facilities where reliable high-volume filtration is required. By selecting the appropriate grade, you can use the same footprint for pre-filtration and final filtration, simplifying spares and maintenance.

Thesvin operates a 50,000 m² manufacturing facility in Zhongshan, Guangdong, China, including 20,000 m² of cleanroom space across six cleanrooms. The quality system is certified to ISO 9001, ISO 14001, and ISO 45001, and in 2024 the company obtained IATF 16949 certification for automotive quality management. Incoming materials, in-process production, and outgoing products are controlled through IQC, IPQC, and OQC procedures to ensure dimensional consistency and batch-to-batch reliability. The company’s CNAS-accredited laboratory can issue test reports for filtration efficiency, dust holding capacity, and resistance, supporting product validation and regulatory compliance. Products meet REACH and RoHS requirements, and compliance documents are available upon request. With over 20 years of experience and more than 1,000 filtration solutions developed, Thesvin supports OEM/ODM projects with custom sizes, structures, media grades, frame materials, logos, and packaging.
To receive a accurate quotation and technical proposal, please provide the following details: device or vehicle model (if applicable), required size or a drawing of the old part, airflow or water flow rate, operating conditions (temperature, humidity, contaminants), and estimated quantity. Our engineering team will review your requirements and respond promptly. Contact Thesvin to start your inquiry.
Thesvin V-Bank filters are available in common face sizes including 592×592×292 mm, 490×592×292 mm, and 287×592×292 mm, which match many standard filter frames. For non-standard units, we customise dimensions to your drawing. Please provide your frame dimensions or the old filter’s size to confirm fitment.
Yes, we welcome old parts for fitment verification. You can send a sample or provide detailed photos and measurements. Our engineers will replicate the interface and recommend the correct V-bank configuration. This helps avoid costly errors and ensures a drop-in replacement.
Thesvin V-Bank filters are available in M6, F7, F8, F9, E10, E11, H13, and H14 grades. H13 and H14 achieve ≥99.95% and ≥99.995% removal for 0.3 μm particles, respectively. Custom grades up to U15/U16 can be quoted on request.
Yes, we provide samples for testing. For standard sizes, we offer 1–2 free samples (freight collect). Custom samples are quoted based on complexity, and the sample fee is deductible from the order. Each sample includes a test report from our CNAS-accredited laboratory.
Standard sizes have a flexible MOQ, typically 10 pieces. Custom models usually require 50–100 pieces. Lead time is 5–7 working days for stock items and 15–25 working days for custom orders after drawing approval. Large orders can be scheduled in batches.
Under normal conditions with proper pre-filtration, the typical service life is 2–3 years. Replace when the final resistance reaches twice the initial resistance (usually around 500–600 Pa) or when airflow drops below 85% of design value. Thesvin can provide a total cost of ownership analysis to optimise your replacement schedule.
Yes, each Thesvin V-Bank filter is individually scanned and tested, and comes with a unique test report from our CNAS-accredited laboratory. The report includes efficiency, resistance, and other key performance data. We can also provide compliance documents for REACH and RoHS.
Yes, we support full OEM/ODM customisation, including frame material (ABS plastic, galvanized iron, aluminium, stainless steel), dimensions, V-bank count, efficiency grade, gasket type, and your logo and packaging. Our team can develop a custom solution within 7–10 days.
