3 Water control models Ceiling models Nine models are available in low profile wall hung, wall hung and ceiling mounted types. Each model has 4 lengths and 5 nozzle arrangements to meet the desired air flow. The vertical units are best suited for under the window applications to counteract downdrafts during the heating season. Horizontal units are the best choice where the use of full length draperies is desirable and heating requirements are not too severe.
