Product Description
ebm-papst EC axial fan W1G154-EG57-11 – ESM, 230V, 2 speeds, IP55
ebm-papst W1G154-EG57-11 is a compact, energy-efficient EC (electronically commutated) axial fan from the ESM series, equipped with 5 swept blades (S series). Thanks to EC technology instead of a conventional induction motor, it delivers significantly lower power consumption, quiet operation, and the ability to switch between two speeds without an additional inverter. It is an ideal replacement in refrigeration equipment, shop furniture, refrigerated cabinets, and HVAC installations that require reliable and efficient air flow.
Key advantages
- EC motor instead of AC: electronically commutated technology › power consumption only 3 W (speed 1) / 2 W (speed 2), which translates into real savings on electricity costs compared to traditional AC fans of the same size.
- 2 speed settings (1300 / 1000 RPM): simple control with a single contact (PIN SL – brown) › the performance and noise level can be adjusted to current demand without additional voltage regulators.
- Swept blades (S series): aerodynamic shape of 5 PA plastic blades › high airflow performance (up to 165 m3/h), low noise level (30–40 dB(A)), and reduced turbulence.
- Ball bearings: high durability and vibration resistance › longer fan life and lower maintenance costs.
- Soft start: smooth start-up eliminates inrush currents › protects the electrical installation and reduces mechanical stress during startup.
- Thermal motor protection + current limiter: automatic protection against overheating and overload › the device is safeguarded even under demanding operating conditions.
- IP55 + environmental class H1: protection against dust and water jets › fully suitable for humid refrigeration and freezer environments.
- Any mounting orientation: no orientation restrictions › design freedom for installations and easy replacement mounting.

FAQ – Frequently asked questions
What supply voltage is required?
The W1G154-EG57-11 fan is powered by 230 V AC, single-phase (1~), 50/60 Hz. It is not suitable for DC or three-phase supply.
How do I switch between speed 1 and speed 2?
Speed control is performed via an external contact connected to the SL (brown, PIN 3) conductor. Open contact = speed 1 (1300 RPM / 3 W), closed contact = speed 2 (1000 RPM / 2 W). No voltage regulator or inverter is required.
What is the IP protection rating?
The fan has an IP55 protection rating, but only when the correct connector supplied by the installer is used. IP55 means full protection against dust and water jets – suitable for humid refrigeration environments.
In which orientation can the fan be mounted?
The fan can be mounted in any position – horizontal, vertical, or inclined. There are no orientation restrictions, providing great flexibility for replacement or installation design.
What is the noise level of the fan?
At speed 1 (1300 RPM) the sound pressure level is 30 dB(A) (free air), and at speed 2 (1000 RPM) only 24 dB(A) – making it one of the quieter fans in this size class.
What is the airflow performance of the fan?
Under free-air conditions: speed 1 – 165 m3/h, speed 2 – 125 m3/h. Maximum static pressure is 11 Pa (speed 1) and 7 Pa (speed 2).
Is the fan suitable for freezer applications?
Yes. The minimum ambient operating temperature is -30 °C, and the minimum transport and storage temperature is -40 °C. Environmental class H1 confirms suitability for humid and cold refrigeration environments.
Is an inverter or voltage regulator required to control the speed?
No. Thanks to EC technology and built-in electronic motor control, speed changes are made via a simple external contact (PIN SL). No inverter or voltage regulator is required.
