To meet the demands placed on modern machinery due to high component density and the resulting problem of heat dissipation, ebm-papst has developed the 4300N high-performance fan. With the same air flow, it can provide an efficiency increase of up to 57% and a decrease in operating noise of about 9 dB(A) compared with its predecessor.
The new fan can be used in all applications involving compact technology, including inverters for welding equipment, drives, photovoltaic systems, automation, IT servers and network technology, and building ventilation. It measures 119 x 119 x 32 mm and features improvements in both its motor and its aerodynamics. Specially formed discharge vanes and innovative winglets on the blade tips improve the aerodynamic efficiency and prevent turbulence that can cause noise.
These compact and efficient motors are available for operating voltages of 12, 24 and 48 V d.c. Their degree of protection can be as high as IP68, depending on the application. The maximum air flow rate is 285 m³/h and the pressure increase can reach 146 Pa, values that exceed those of the previous model by up to 50%.
