In a refrigeration system in which coils are mounted in a coil passage, a fan system is provided by which air is caused to pass over the coils. The fan system includes a housing communicating with a coil passage. The housing has an inlet and an outlet each with a mouth, the mouths of the inlet and outlet being oriented substantially 180 DEG from one another. A cylindrical, elongated transverse flow fan is mounted in the housing transversely thereof and an electric motor is connected to rotate the fan. An inlet baffle extends around a part of the fan. An outlet baffle has a scoop part with a free edge extending along the length of the fan, spaced radially from the fan a short distance, and off set toward the outlet mouth. The outlet baffle, including the scoop part, defines one service of a passage to the outlet mouth. The air that passes through the housing flows through the inlet and the outlet mouths in planes substantially parallel with one another.
