Circulate warm or cool air from 1 room to another using this through wall fan. This hard-wired room-to-room fan unit is often used in conjunction with PTAC units, mini-splits, fireplaces, wood stoves, window air conditioning units, and other heating and cooling systems. The telescoping housing on this wall-mounted exhaust fan installs in framed walls from 4 to 6-1/2 inches thick. A variable-speed fan allows you to adjust the air transferring power to quickly change or maintain temperatures in adjoining rooms. The airflow transfer fan's grille can be painted to match your interior style. The rotating grille allows the airflow direction to be changed for your customized comfort. This air transfer fan needs to be hard-wired in order to supply power to the unit and operate. Whether you are trying to keep a room cold in the summer, or warm throughout the long days of winter Suncourt ThruWall Hard Wired Variable Speed Room to Room Air Transfer Fan has you covered.
