ebmpapst S4D400AP1204 fan

Axial fan EBM PAPST S4D400-AP12-04 (S4D400-AP12-04) – Maximum airflow 4000 m³/h. Buying the powerful axial fan EBM PAPST S4D400-AP12-04 is a professional solution for tasks requiring high performance in a compact size. The model with a 400 mm diameter and three-phase motor is designed for continuous operation in industrial equipment, cooling systems, and supply ventilation. The S4D400-AP12-04 belongs to the S series (axial fan with protective grille) and is equipped with a 4-pole AC motor M4D074-EI. Thanks to five sickle-shaped blades made of stamped steel with polymer coating, the unit demonstrates excellent aerodynamics and corrosion resistance. Why choose S4D400-AP12-04? 1. Record performance for the 400 mm size – The fan moves up to 4000 m³/h at 50 Hz. When switching to 60 Hz, airflow increases to an impressive 4610 m³/h at static pressure of 120 Pa. This is an ideal choice for cooling powerful condensers, ventilation of server rooms, and production workshops. 2. Energy efficiency and reliability – Despite the huge airflow, the motor consumes only 135 W (current 0.76 A). Maintenance-free ball bearings and operating mode S1 (continuous) ensure a service life in 24/7 mode without replacing lubricant. Insulation class "F" guarantees resistance to overheating. 3. Operation in extreme conditions – Operating temperature range is from -25°C to +80°C, allowing the fan to be used outdoors, in unheated warehouses, and cold rooms. Protection class IP44 protects the mechanism from dust and water splashes. 4. Low noise level – Unique blade geometry reduces turbulence. Noise level is 68 dB(A), significantly quieter than analogues. Technical specifications (summary): Model: S4D400-AP12-0
