F9 V-Bank Filters
The Airtech V-Bank does the same job as a standard pocket filter (F9 fine particle filtration) but starts at a lower resistance, so the AHU fan works less hard. ABS plastic frame. We hold both full-size and half-size formats in stock at our Silverton warehouse. Call with your AHU frame size and we will confirm availability.

The Airtech F9 V-Bank filter is a high-efficiency, lower-resistance alternative to traditional pocket bag filters. Built on a compact mini-pleat design with a large media surface area packed into a V-shaped configuration, it delivers F9 filtration at a lower starting resistance than a standard pocket filter. The result is a lower fan load. The frame is ABS plastic.
Full-size (592×592×292mm) and half-size (592×287×292mm) formats are held in stock in Silverton, Pretoria, with nationwide delivery quoted at checkout on online orders. Order any quantity online, from a single filter up to full sealed boxes. Custom sizes are manufactured on a 7-10 day lead time.
Why V-Bank over Pocket Filters?
A standard F9 pocket filter presents approximately 225 Pa of resistance at 3 400 m³/h. The Airtech V-Bank at the same airflow presents 110 Pa. Lower resistance means a lower fan load while the filter is in service.
The extended media area also means the V-Bank holds more dust before reaching its final pressure drop of 400–450 Pa. Because the V-Bank starts at a much lower initial resistance (110 Pa vs 225 Pa for a pocket filter), it takes significantly longer to reach that replacement threshold, giving you more filter life from every unit. Fewer replacements per year means lower labour and consumable costs for maintenance teams.
For facilities specifying secondary filtration before a terminal HEPA stage, the V-Bank reduces the load on the HEPA filter by presenting cleaner air at lower pressure, extending the HEPA service life as well. And for any facility that requires G4 pre-filtration upstream, the standard G4 panel filter at the first stage protects the V-Bank from coarse loading and is a required part of the filtration system design.

F9 V-Bank filters are specified wherever high-efficiency secondary filtration is required with minimal impact on fan energy. Their compact depth and low resistance make them suitable across a range of demanding commercial and industrial HVAC applications.
V-Bank sits at the secondary stage before terminal HEPA, extending the HEPA service life by presenting pre-cleaned air at low pressure.
F9 filtration at lower resistance. The V-Bank's reduced resistance directly lowers power consumption in energy-sensitive data centre environments where AHU fans run continuously at high duty.
Secondary-stage filtration in hospital AHU systems protecting downstream terminal HEPA filters from fine particle loading. Lower resistance means more efficient air handling in patient-sensitive environments.
Shopping centres, airports, and large office buildings with high filter counts benefit from fewer replacements per year and lower maintenance costs compared to equivalent pocket bag filter installations.
Provides fine particle filtration before HEPA with less load on the AHU fan than a pocket filter at the same grade. Compatible with cleanroom filter banks requiring compact depth at secondary stage.
Existing AHUs running pocket filters can be upgraded to V-Bank for a lower starting resistance. Both full-size (592×592mm) and half-size (592×287mm) formats cover the most common secondary-stage cell dimensions.
What is a V-Bank filter and how does it differ from a pocket filter?
A V-Bank filter uses a compact mini-pleat media folded into a V-shaped pack inside a rigid frame, giving a much larger media surface area than a pocket bag filter. This larger area means the filter offers significantly lower resistance to airflow at the same F9 filtration grade: 110 Pa vs 225 Pa for a standard pocket filter at 3 400 m³/h.
Does a V-Bank use less fan energy than a pocket filter?
It starts at a lower resistance: 110 Pa against 225 Pa for a standard F9 pocket filter at 3 400 m³/h. Lower resistance means the AHU fan works less hard to move the same air. The actual saving depends on your fan, your airflow and how long the filter stays in.
How often should V-Bank filters be replaced?
Replace when the differential pressure across the filter reaches 400–450 Pa. In typical commercial or pharmaceutical HVAC applications this is every 12–18 months, compared to 6–12 months for a pocket filter at the same grade. The extended service life is a direct result of the lower initial resistance and larger media area.
Can V-Bank filters replace pocket filters in existing AHUs?
In most cases, yes. The Airtech 592×592×292mm V-Bank is designed to fit standard AHU secondary-stage filter banks. Verify the cell depth is at least 292 mm and that the face dimensions match. Our full-size (592×592mm) and half-size (592×287mm) formats cover the most common AHU configurations. Call us with your AHU model and frame dimensions to confirm compatibility.
Do you deliver V-Bank filters nationwide?
Yes, delivery is available nationwide across South Africa. Delivery is charged at the live courier rate for your address, shown at checkout. We hold both full-size and half-size V-Bank filters in stock at our Silverton, Pretoria warehouse, where you can also collect at no charge.
What certification do your V-Bank filters have?
Manufactured to EN779:2012 F9 with average efficiency of 95% or higher at 0.4 µm. Note: individual test certificates are supplied only with HEPA filters (H13 and H14), not with V-Bank or other non-HEPA grades.
