The Lobisong LBE2E175-133NS-01 is a high-power 175mm EC centrifugal fan engineered for the most demanding ventilation and heat-dissipation tasks. Driven by a 230V EC motor rated at 133W, this industrial centrifugal blower delivers up to 924m³/h of airflow and 893Pa of maximum static pressure, making it one of the strongest EC centrifugal fans in its size class. The integrated EC controller supports 0-10VDC and PWM speed regulation, with stall, reverse-polarity, over-voltage and soft-start protection built in. IP55 protection, Class F insulation and maintenance-free ball bearings ensure reliable operation of this backward curved centrifugal fan from -25°C to +60°C.

High static pressure and high airflow rarely come from a compact package, but the Lobisong 175mm EC centrifugal fan delivers both. Air is drawn axially into the high-performance plastic impeller, accelerated along backward-curved blades and discharged radially at 90° to the shaft. This aerodynamically optimized path converts motor torque into static pressure with minimal turbulence, so this centrifugal fan maintains stable air delivery against dense filters, heat exchangers and long duct runs.

With 133W of EC power and speeds up to 5030RPM, this 175mm EC centrifugal fan moves 924m³/h at up to 893Pa, outperforming many larger blowers in a compact footprint. The rigid plastic impeller resists oxidation and mild corrosive gases, extending the service life of this centrifugal blower under continuous full-load operation. For OEMs, this EC blower provides class-leading performance with the energy flexibility of EC speed control.

To summarize, the Lobisong 175mm EC centrifugal fan is a high static pressure fan that pairs a backward curved centrifugal fan design with 133W of EC power. As an industrial fan and an HVAC blower, this 175mm EC centrifugal fan delivers 924m3/h of airflow as a variable speed fan, making it one of the most capable centrifugal blowers in its class.

1. High Static Pressure up to 893Pa

The steep pressure curve of this backward curved centrifugal fan lets it drive air through dense HEPA filters and tight heat-exchanger matrices without stalling. For applications that need a high static pressure fan, the 175mm model is a dependable choice.

2. High Airflow of 924m³/h from a 175mm Frame

This 175mm EC centrifugal fan delivers up to 924m³/h, giving equipment designers generous cooling headroom in a compact footprint that fits standard cabinet layouts and simplifies machine integration.

3. EC Speed‑Regulating Flexibility

The integrated EC controller of this centrifugal fan supports 0-10VDC and PWM signals, so integrators can balance airflow, power and noise against heat load. This makes the EC blower an effective variable speed fan for dynamic thermal environments.

4. Heavy‑Duty Protection and Reliability

Stall, reverse-polarity, over-voltage and soft-start protection are standard on this EC centrifugal fan, and the S1 continuous-duty rating supports long, unattended operation in production machinery and process ventilation.
