These are fixed, ducted commercial fans, not portable cooling fans. We stock the Systemair KVK Slim, KVK Silent and KVK Duo, the Elta Singleflow, Twinflow, Multiflow, Hideaway and Qube ranges, and the Vent-Axia Quiet Pack and Slimpak, from 100mm to 700mm with AC and EC motors.

Box fans deliver good airflow against the resistance of ducts, grilles and filters in a compact footprint that fits in ceiling voids, risers and plant rooms.\u003c\/p\u003e\n\n\u003ch3\u003eIs this the same as a domestic box fan?\u003c\/h3\u003e\n\u003cp\u003eNo. A domestic box fan is a portable fan that stands on the floor or in a window to cool a room. A commercial box fan is fixed into ductwork and drives a whole ventilation system. If you are looking for a portable cooling fan, this is not the right range.\u003c\/p\u003e\n\n\u003ch3\u003eCentrifugal or mixed flow box fan?\u003c\/h3\u003e\n\u003cp\u003eCentrifugal box fans, such as the Systemair KVK, Elta Singleflow, Twinflow and Qube, cope well with higher system resistance from long duct runs, filters and attenuators. Mixed flow box fans, such as the Elta Multiflow SMB, move more air for their size on lower resistance systems. If the system has a lot of ductwork or filtration, start with a centrifugal fan. For a straight inline mixed flow duct fan, see our \u003ca href=\"\/collections\/inline-mixed-flow-fans\"\u003ein-line fans\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhich box fans fit a shallow ceiling void?\u003c\/h3\u003e\n\u003cp\u003eLow profile ranges are built for this: the Systemair KVK Slim, the Vent-Axia Slimpak and the Elta Hideaway. Each product page lists the casing height, so check it against the void depth, and allow room for the duct connections and access to the terminal box.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is a twin box fan?\u003c\/h3\u003e\n\u003cp\u003eA twin fan, such as the Systemair KVK Duo or KV DUO, has two fans in one casing set up as run and standby. If the duty fan fails, the standby fan takes over, so ventilation keeps running. It suits systems that must not stop, such as commercial toilets and plant rooms.

EC fans use less energy, especially at reduced speed, run quieter when turned down and are fully variable through a 0-10V signal, which makes them easy to link to a BMS, timer or sensor. Use the buttons below to filter by motor.\u003c\/p\u003e\n\n\u003ch3\u003eSingle phase or three phase?\u003c\/h3\u003e\n\u003cp\u003eMost small and mid size box fans run from a standard 230V single phase supply. The larger sizes and higher duty models are often three phase. Use the buttons below to filter by supply, and check what is available at the fan position before choosing.\u003c\/p\u003e\n\n\u003ch3\u003eCan box fans be used for kitchen extract?\u003c\/h3\u003e\n\u003cp\u003eStandard box fans are for clean or lightly contaminated air. For hot or greasy kitchen extract, use a fan rated for it, such as the Elta Qube SQUHT, rated for extract air up to 120°C, with grease filtration at the canopy. See our \u003ca href=\"\/collections\/high-temperature-fans\"\u003ehigh temperature fans\u003c\/a\u003e and \u003ca href=\"\/collections\/commercial-kitchen-extractor-fans\"\u003ecommercial kitchen extractor fans\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I size a commercial box fan?\u003c\/h3\u003e\n\u003cp\u003eWork out the airflow the space needs, in m³\/h or l\/s, then add up the resistance of the system: ductwork, bends, grilles, filters and any attenuators or heat recovery.
