Description
The ebm-papst D4E133-DL01-H9 (also known as D4E133DL01H9) is an industrial-grade, dual-inlet forward-curved AC centrifugal blower powered by an integrated M4E068-CF external rotor motor housed within a 203 x 213 x 232 mm (7.99 x 8.39 x 9.13 in) galvanized sheet steel scroll casing. Designed for continuous single-phase 230 VAC operation at 50/60 Hz, the blower achieves speeds up to 1200 RPM with an input power draw of 80 W (50 Hz) / 95 W (60 Hz) and delivers a free-air flow rate of 440 CFM (750 m³/h). Aerodynamically balanced PA plastic impellers and maintenance-free dual ball bearings ensure smooth, quiet operation across diverse operating orientations. Comprehensive protection is built in via an internal thermal overload protector (TOP), IP44 ingress sealing, and a robust 4-conductor PVC cable assembly.
Key Features
- Dual-Inlet Scroll Housing: Heavy-gauge galvanized sheet steel scroll casing delivers optimized airflow dynamics and long-term corrosion resistance.
- External Rotor Drive: Integrated single-phase M4E068-CF motor provides compact spatial packaging and high operating efficiency across both 50/60 Hz.
- PA Plastic Impeller: Forward-curved multi-blade wheel engineered from durable polyamide plastic ensures low vibrational acoustics and high structural rigidity.
- Thermal Overload Protection: Internally wired thermal cut-out automatically shields motor windings from prolonged locked-rotor and over-temperature fault states.
- Universal Mounting Stance: Maintenance-free precision ball bearing system supports S1 continuous operation in any required spatial installation plane.

Applications
The ebm-papst D4E133-DL01-H9 dual-inlet centrifugal blower is engineered for ducted industrial and commercial air-movement equipment requiring dependable laminar ventilation against moderate system back pressures. Common OEM integration points include ducted fan coil units, heat recovery ventilation (HRV) modules, commercial kitchen range hoods, and forced-air drying or curing tunnels. It also serves as a critical MRO replacement component within electronics enclosure heat exchangers, laboratory fume extraction systems, and laminar clean benches.
