Roof Fans / Axial Fans / Inline Fans / Replacement Filters

What Systemair fans do you stock?

We stock Systemair fans across most commercial and industrial fan types. The range includes cased axial fans from 315mm to 800mm for general ventilation and extract applications, plate axial fans for wall- and panel-mounting, inline duct fans in circular sizes from 100mm to 630mm, and roof fans including the DHS Sileo range for low-noise roof extract. Most Systemair fans are available in both AC and EC motor variants — EC motors offer variable speed control, lower energy consumption and longer service life. Fan sizes range from 100mm domestic connections up to 800mm for large commercial and industrial duct systems. 

Do you stock Systemair speed controllers?

Yes — we carry Systemair fan speed controllers for both single-phase and three-phase fan motors. The range includes transformer-based speed controllers for AC fans (step control), electronic speed controllers with 0–10V output for EC fans, and thermostatic controllers with built-in temperature sensing for automatic fan speed regulation. Systemair speed controllers are matched to specific fan power ratings, so it is important to select the correct controller for the fan motor current. If you are unsure which Systemair controller suits your fan, contact us at hello@efans.co.uk with your fan model number and we will confirm compatibility.

What Systemair Villavent MVHR filters do you stock?

We stock replacement filter sets for the Systemair Villavent range of MVHR heat recovery units, including filters for the VR 250 EH/B, VR 300 TK/B, VR 400 DCV/B, VR 400 EV/B and VX 400 E/EV. Villavent was acquired by Systemair and the MVHR units were previously sold under the Villavent brand name — many are still installed in UK homes and require ongoing filter replacement. Our Villavent filters are stocked as pocket filter sets (supply and extract) and ship with next-day delivery. MVHR filters should be replaced every six to twelve months depending on usage and local air quality. Use our Filter Finder tool to match the correct filter to your Villavent unit.

What are Systemair roof fans?

Systemair roof fans are designed for permanent installation on flat or pitched roofs to provide continuous or intermittent extract ventilation for commercial and industrial buildings. The range includes the DHS Sileo series — low-noise vertical discharge roof fans with backward-curved impellers — and the TFSR range of horizontal discharge roof fans for applications where vertical discharge is not suitable. Roof fans are available in sizes from 225mm to 630mm, with airflow rates from around 600 m³/h up to over 10,000 m³/h depending on the model. All Systemair roof fans include a galvanised steel base and are designed for use with standard roof cowls and weathering kits. Browse our full roof fan range or contact us for sizing advice.

Do you stock Systemair ducting and accessories?

Yes — we carry a range of Systemair ducting products and accessories alongside the fan range. This includes aluminium flexible ducting in sizes from 82mm to 800mm in 10-metre lengths, combi flexible ducting (outer PVC, inner aluminium) in 6-metre lengths, circular weather louvres with mesh screens, gravity louvre shutters, backdraft dampers, fast clamps, matching flanges, protection guard grilles and in-duct filter boxes with G3 and M5 filter grades. These accessories are designed to work with Systemair fans and standard circular duct systems, and all stocked items ship with next-day delivery.
