TRANE TWE/4TEE features: The Comfort-R™ difference Trane’s exclusive Comfort-R feature represents the ultimate in
comfort. Most standard air handlers have only three fan speeds. Ours has twelve. The result? More consistent temperatures, greater humidity control and better air heating.
Air-Tite™ construction Special insulation, door gaskets and thermal seals effectively sea in conditioned air, increasing efficiency and reducing your heating and cooling costs.
Quiet comfort More speeds mean your air handler operates at the lowest effective speed much of the time.
Better, cleaner air Since the air handler operates at slower speeds, air is drawn through your filters more gradually, allowing more thorough air cleaning.
