A walk-in would have a thermostat, but the reversible switch is not a standard walk-in feature, although it could be handy for a forced defrost. Speed would also not a standard walk-in feature,but it could function as a load control of sorts.

My best guess is it is exactly what it appears to be, a window fan. I have never heard of Penguinaire brand.
