Description
The ebm-papst D1G160-DA33-15 is a high-performance EC dual-inlet centrifugal blower featuring a 160 mm diameter impeller, a nominal voltage of 48 VDC, and a power consumption of 112 W. This unit is constructed with a galvanized sheet steel housing and impeller, utilizing a dual ball bearing system for extended operational life. The motor is an electronically commutated (EC) M1G074-CF model, providing a maximum free-air flow rate of 985 m3/h at a nominal speed of 1250 RPM. Its forward-curved blades are designed for efficient air displacement within a compact footprint, and the assembly includes integrated electronics for speed control via a 0-10 VDC or PWM signal, alongside a tachometer output for performance monitoring.
