Wall Mounted Extraction Fan Axial 450mm 190W IP44 5500m³/h 85Pa, Ferono

Quick Facts — Ferono Wall Fan FPT450

• Axial fan for wall mounting, diameter 450 mm
• Brushless motor with double bearings
• Airflow 5500 m³/h, power 190 W
• Protection class IP44, insulation class F
• Motor and blades in metal
• Protective grille on both sides of the blade assembly
• 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.

Why installers choose the FPT450 as the mid-size option in the series

The FPT450 fills the gap between the series' smallest and mid-range models, with an airflow of 5500 m³/h and a power consumption of 190 W. This makes it a balanced choice when the FPT400 feels underpowered but the FPT500 offers more capacity than the space requires. The brushless motor with double bearings and insulation class F gives the same industrial durability as the rest of the series.

What noise level does the FPT450 produce during operation?

At 75 dB, the FPT450 sits slightly above the larger FPT500 and FPT550 models (74 dB each), despite its smaller diameter. This is due to the higher speed relative to blade size. When noise level is a deciding factor in model selection, this should be weighed against the airflow actually needed.

Where does the FPT450 fit in an installation?

The model suits wall-mounted ventilation in smaller to medium-sized workshops, storage spaces and production premises where an airflow between the series' smallest and mid-range model is required. It withstands the same demanding operating conditions as the rest of the series, including protection class IP44 and a wide temperature and humidity range.

Frequently asked questions (FAQ)

Why is the noise level of the FPT450 (75 dB) higher than the larger FPT500 and FPT550 models (74 dB each)?

Noise level depends on several factors beyond diameter, including blade profile and speed relative to airflow. The FPT450 runs at the same speed, 1350 RPM, as the FPT400 but drives a larger airflow, which may explain the slightly higher noise level despite the smaller diameter compared with the FPT500 and FPT550.

Can the FPT450 replace the FPT400 if airflow requirements increase?

Yes, the FPT450 delivers 5500 m³/h compared with 4500 m³/h for the FPT400, an increase of approximately 22%, while power consumption rises only from 170 W to 190 W. The mounting dimensions differ, however (450 mm versus 400 mm diameter), so the duct opening or wall space must be checked before switching.

What sets the FPT450 apart from the next size up, the FPT500?

The FPT450 has lower airflow (5500 versus 6570 m³/h), lower power (190 versus 320 W) and a smaller diameter (450 versus 500 mm), but shares the same motor technology, protection class IP44 and operating temperature range. The FPT450 is the right choice when the FPT400's capacity is not enough but the FPT500's larger size and power consumption are not justified.
