1. Fresh Air Intake

Air recycled indefinitely can become stale and stagnant with air quality suffering significantly. Fresh air is the answer and it is for this reason that the PMFY- series takes in air directly from outdoors. This fresh air intake allows you to enjoy the comfort of crisp, refreshing air in the confines of your living or working space.

2. Light and Compact

The main unit weighs only 31 lb. and the panel merely 7 lb. This makes the PMFY- series one of the lightest in the industry. The unit size is also quite small, having been standardised to a strikingly compact 33-5/8 inch. All of this make the chore of installation and maintenance that much simpler and easier.
