CITY MULTI VRF - Indoor Units



PFFY floor-standing models are available as exposed or concealed indoor units.  At less than nine inches deep, these units are easy to install in peripheral spaces, yet offer highly efficient air-conditioning performance. Their low operating sound and compact size make them ideal for hotel rooms, schools and office buildings. The PFFY offers tremendous flexibility in two distinct versions:


PFFY-NEMU - exposed-type model, perfect for most applications and requires no finish work.


PFFY-NRMU - designed for applications requiring a built-in, concealed, floor-standing unit.


  • Available in 6,000, 8,000, 12,000, 15,000, 18,000 and 24,000 Btu/h capacities
  • Two-speed fan settings
  • PFFY units can house either a Deluxe MA or ME Remote Controller in the top corner (under a cover panel)
