Cool Air Where You Need It

COOL AIR is ducted through a center duct to deliver the air where it is most appreciated. Adjustable vents are installed for each passenger to Fine Tune the flow!


Systems That Work

Inlet and outlet air are ducted inboard and overboard by a vent on each side of the aft fuselage, precluding exhaust ingestion.
