The EasyCollar universal collar and the DeflectAir deflector from Marketair are designed to enhance all brands of ductless and VRF/VRV ceiling cassettes in new construction and retrofit applications. The EasyCollar is a universal one-piece collar, moulded from glass fibre reinforced plastic. It comes in three sizes, each of which are available in multiple depths from two to 12-inches. The DeflectAir models deflect air in four directions to eliminate hot or cold drafts. They mount underneath the cassette without compromising airflow or access for filter replacement. Both are moulded from Class II fire-resistant resin.
