Description
ebm-papst 4606ZW is an industrial-grade AC axial cooling fan engineered for high-reliability thermal management across demanding electronic and electrical enclosures. Housed in a standardized 119 x 119 x 38 mm (4.69 x 4.69 x 1.50 in) square metal frame, the unit incorporates an all-metal impeller and die-cast housing designed to withstand elevated mechanical and thermal stress. Electrical operation is rated for single-phase 115 VAC at 50/60 Hz, delivering rotational speeds of 2650 RPM (19 W) at 50 Hz and 3100 RPM (18 W) at 60 Hz. Aerodynamic discharge flows over the structural struts in a clockwise direction relative to the rotor, generating free-air delivery up to 152 m³/h (89.5 CFM) at 50 Hz and 180 m³/h (105.9 CFM) at 60 Hz. Engineered with a precision dual ball bearing system and impedance overload protection, the assembly is terminated with 310 mm AWG 20 lead wires for standardized integration.
Key Features
- 50/60 Hz Electrical & Aerodynamic Performance: Operates on 115 VAC nominal voltage (±10%), consuming 19 W at 2650 RPM (50 Hz) and 18 W at 3100 RPM (60 Hz), with maximum airflow ratings of 152 m³/h (89.5 CFM) and 180 m³/h (105.9 CFM) against static pressures up to 70 Pa (50 Hz) and 80 Pa (60 Hz).
- Rugged All-Metal Construction: Manufactured with a heavy-duty die-cast metal housing and matched metal impeller, ensuring high structural integrity, flame resistance, and continuous dimensional stability in harsh environments.
- Long-Life Bearing System & Orientation: Built with high-precision ball bearings and a balancing grade of 2.5, allowing installation in any arbitrary shaft orientation without compromising operational life or acoustic consistency.
- Integrated Impedance Motor Protection: Designed with an impedance-protected shaded-pole motor architecture that prevents thermal damage and coil burnout during continuous locked-rotor fault conditions.
- Standardized Mechanical & Electrical Interface: Standard 119 mm square footprint with 104.8 mm mounting hole spacing (M4 screw clearance) and pre-stripped 310 mm (12.2 in) AWG 20 dual black lead wires for fast system connectivity.
