The Lobisong LBBE3G175‑072PS‑01 is a 175mm EC outer rotor centrifugal fan specially engineered for air purification equipment and precision ventilation systems. Featuring a PA6+GF reinforced plastic impeller and an aluminum alloy bracket, this outer rotor centrifugal blower runs on 200‑277V AC at 50/60Hz with just 55W input, delivering up to 536m³/h of airflow and 453Pa of static pressure at 65dB(A). The compact outer rotor motor structure saves space while improving efficiency and balance. Built‑in 0‑10VDC/PWM control and stall, reverse‑polarity, over‑voltage and soft‑start protection ensure safe, stable operation of this EC centrifugal fan from -25°C to +60°C, with CE, RoHS, BSCI and CCC certifications.

Air purification systems demand blowers that are compact, quiet and precisely controllable. The Lobisong 175mm EC outer rotor centrifugal fan meets these requirements with a PA6+GF impeller, aluminum alloy bracket and an outer rotor motor that wraps the rotor around the stator for a short, balanced construction. Air enters axially, accelerates along backward‑curved blades and exits radially at 90°, generating stable static pressure with low turbulence noise. As an air purification fan, this centrifugal fan is tuned for the airflow and pressure range that filter systems need.

Operating across 200‑277V AC at 50 or 60Hz, this EC centrifugal fan adapts to global power grids without transformer changes, simplifying international product design. Its 55W input keeps energy consumption low, while the corrosion‑resistant PA6+GF impeller and aluminum bracket withstand long continuous duty. With CE, RoHS, BSCI and CCC compliance, this EC blower meets the certification requirements of major global markets.

To summarize, the Lobisong 175mm EC outer rotor centrifugal fan combines an outer rotor centrifugal fan motor with a PA6+GF impeller that makes it a true air purification fan. As a 200‑277V EC fan and a low noise blower, this backward curved centrifugal fan meets the airflow needs of purifiers, while the EC blower design keeps energy use low.

This air purification fan is also a 200‑277V EC fan that runs on both 50Hz and 60Hz grids for global OEM projects.

The PA6+GF impeller of this centrifugal fan and the low noise blower structure keep purifiers quiet and reliable.

As an EC blower, this EC centrifugal fan offers 0‑10VDC and PWM control for filter‑loaded purification systems.

The backward curved centrifugal fan design of this outer rotor centrifugal fan maintains stable airflow as filters load with dust.

1. Outer Rotor Motor Structure

The outer rotor design wraps the rotor around the stator, producing a compact, well‑balanced EC centrifugal fan with high torque density, low vibration and reduced axial length. This outer rotor centrifugal fan structure is a major advantage for slim air purification housings.

2. PA6+GF Impeller and Aluminum Alloy Bracket

Glass‑fibre reinforced PA6 delivers strength, dimensional stability and corrosion resistance, while the aluminum bracket keeps this centrifugal blower light and rigid for long continuous operation without performance drift.

3. Wide 200‑277V AC Input, 50/60Hz

One EC fan covers global single‑phase grids from 200V to 277V at both 50Hz and 60Hz, reducing inventory variants and simplifying export machine design for manufacturers worldwide.

4. EC Speed Control for Precise Airflow Matching

0‑10VDC and PWM speed inputs allow exact airflow tuning of this centrifugal fan, which is essential for air purification equipment where filter loading continuously changes system resistance.
