The R1G190-AB27-02 from EBM-Papst is a DC-powered centrifugal fan with backward-curved blades, designed for demanding ventilation and air handling applications. The fan delivers up to 615 m³/h at 24 V DC and is excellently suited for industrial systems where a compact size and high performance are crucial. With a 190 mm housing and black painted finish, it is easy to integrate into existing designs.
Thanks to the built-in EC motor with soft start, PWM/0–10 V control input, and current limit control, the fan is well-suited for energy-efficient systems with variable flow requirements. The mounting position is optional, providing great flexibility during installation.
