bathroom and basement should not be stuffy and musty, and the living room requires low-footprint appliances. The Zephyr exhaust fan, from the Penn (TM) ventilation systems by PennBarry, offers great variety for particular air distribution applications. It supposedly holds the most ceiling fan options of any manufacturer.
The Penn Zephyr exhaust fan comes in 17 models spaced evenly all throughout the spectrum of CFMs and static pressures, with several combinations of wheel sizes and speeds, in a selection of capacities, for low or medium pressure, for ceiling, room, wall or inline mounting. Lek-Trol speed adjustment ensures that ventilation needs are met precisely, whether mounted remotely or on the unit. Dual-speed motors can shift nominal speeds from 1050 to 1550 RPM.
