Elta Fans

Frequently asked questions

What Elta fans do you stock?

We stock Elta products across most commercial and industrial fan types, plus a residential ventilation range. The commercial range includes Clearflow axial roof fans from 315mm to 630mm for rooftop extract applications, compact plate axial fans from 250mm to 630mm for wall- and panel-mounting, long cased axial fans for ducted installations, and box fans for plant room applications. The VL series of inline duct fans covers sizes from 100mm to 315mm for general ventilation and extract. For residential properties, the Silent Jetflow SJMF range of inline mixed-flow fans (100mm, 125mm, 150mm) provides quieter operation with EC motors, and the FLUX dMEV 100 is a continuous extract fan for bathrooms. Fan sizes range from 100mm to 710mm.

What are Elta Clearflow roof fans?

The Elta Clearflow range is a series of axial roof fans designed for permanent installation on flat or pitched roofs for commercial and industrial extract ventilation. Clearflow fans operate at temperatures up to +60°C and can be mounted at angles up to 30°, making them suitable for a wide range of roof pitches and plant room installations. The range includes the CF315, CF400 and CF450 models in single-phase and three-phase variants, with airflow rates from around 1,300 m³/h up to over 5,200 m³/h depending on the model. All Clearflow roof fans include a galvanised steel base and are speed-controllable. Browse our full roof fan range or contact us for sizing advice.

Do you stock Elta heat recovery and PIV units?

Yes. The Trade FLUX HR is a single-room through-wall heat recovery unit available in 100mm and 150mm sizes, delivering up to 25 m³/h (100mm) and 60 m³/h (150mm). It recovers heat from outgoing stale air and is designed for retrofit installations where full MVHR ductwork is not practical. The Elta PIV ONE is a loft-mounted positive input ventilation system that draws filtered air from the loft space into the home to reduce condensation and improve indoor air quality, delivering up to 216 m³/h with a 5-year warranty. Both products are in stock with next-day delivery.

Do you stock Elta fan speed controllers?

Yes, we carry Elta fan speed controllers for both AC and EC motor fans. The range includes the 149-EL31 (3 Amp) and 149-EL61 (6 Amp) electronic speed controllers for single-phase AC fans, providing stepless variable speed control from 110–240V. For EC fans, the 149-POT-10-MI controller provides 0–10V output for precise speed regulation. Thermostatic variants (149-EL31TK, 149-EL61TK) include built-in temperature sensing for automatic fan speed adjustment. Elta speed controllers are matched to specific fan power ratings, contact us at hello@efans.co.uk with your fan model number if you need help selecting the right controller.

What are Elta Silent Jetflow fans?

The Elta Silent Jetflow SJMF range is a series of inline mixed-flow duct fans with EC motors, designed for installations where low noise and energy efficiency are priorities. The range covers 100mm, 125mm and 150mm duct sizes, delivering airflow rates from 241 m³/h (SJMF 100) up to 518 m³/h (SJMF 150). Mixed-flow impeller design means the Jetflow fans generate higher pressure than a standard axial fan of the same size, making them better suited to longer duct runs or installations with multiple bends. All Jetflow fans are speed-controllable and suitable for kitchen extract, bathroom ventilation and commercial applications.
