Wall Mounted Extraction Fan Axial 250mm 56W IP44 1770m³/h 38Pa, Ferono

Quick Facts — Ferono Wall Fan FPT250

• Axial fan for wall mounting, diameter 250 mm
• Brushless motor with double bearings
• Airflow 1770 m³/h, power only 56 W
• Noise level 55 dB — quietest and smallest in the series
• Protection class IP44, insulation class F
• Motor and blades in metal
• Operation from -20°C to 80°C, humidity 20–85%

An axial fan for wall mounting with a brushless motor and protective grilles on both sides of the blade assembly. The motor and blades are made of metal, and the aerodynamically profiled blades give efficient airflow on a single-phase power supply.

The brushless motor is prepared for voltage regulation and is protected against overheating via a built-in temperature sensor in the windings. The fan is rated to protection class IP44 and withstands demanding operating temperatures and humidity.

What makes the FPT250 the most compact model in the series?

With a diameter of just 250 mm and a weight of 3.0 kg, the FPT250 is the smallest and lightest model in the series. The power consumption of 56 W and current draw of 0.25 A make it an energy-efficient option where airflow needs are limited, for example in smaller technical spaces or as a complement to a larger main fan.

How quiet is the FPT250 compared with the rest of the series?

The FPT250 has a noise level of 55 dB, significantly lower than both the FPT400 (65 dB) and the larger models (74–75 dB). This makes it the natural choice when the fan needs to sit near workspaces or in areas where noise is a particular concern, while the airflow of 1770 m³/h still provides meaningful ventilation for smaller volumes.

Is the FPT250 suited to spot extraction in tight spaces?

Yes, the compact size and smaller mounting dimensions (including a narrower F dimension of 52 mm versus 60 mm for the other models in the series) make the FPT250 suitable for tight installation sites such as smaller storage rooms, server cabinets, technical recesses or compact wet rooms. Despite its size, it shares the same industrial base construction, protection class IP44 and operating temperature range as the series' larger fans.

Frequently asked questions (FAQ)

Is the FPT250's airflow sufficient for more than a small technical space?

The FPT250 delivers 1770 m³/h, considerably less than the rest of the series (from 4500 m³/h upwards), and is therefore best suited to smaller volumes such as technical cabinets, server rooms or compact wet rooms rather than entire workshops or production halls. For larger premises, one of the series' larger models should be chosen instead.

Can the FPT250 be installed in spaces with limited installation depth?

Yes, the FPT250 has the smallest mounting dimensions in the series, including a total mounting depth (dimension C) of 320 mm compared with up to 620 mm for the largest models. This makes it suitable for installation sites where the space behind the wall is limited.

What sets the FPT250 apart from the next size up in the series, the FPT400?

The FPT250 has significantly lower airflow (1770 versus 4500 m³/h), lower power (56 versus 170 W) and a smaller diameter (250 versus 400 mm), but shares the same motor technology, protection class IP44 and operating temperature range. The gap in capacity is large enough that the FPT250 should primarily be used for distinctly smaller airflow needs rather than as a generally cheaper alternative to the FPT400.
