Dampers
Master Flow Dampers balance and adjust the air flow in individual runs of round pipe in HVAC systems. The dampers include hardware that makes it easy to install into existing round pipe as well. They are constructed of galvanized steel for durability. Only one wing nut is required for installation.
- Spring-loaded hardware for easy mounting into existing round pipe
- Helps to control airflow in a run of pipe
- Always insulate ductwork for greater system efficiency and comfort
Circulate warm or cool air from one room to another using this ThruWall Pro Room to Room Fan. Hardwired unit is often used in conjunction with PTAC units, mini-splits, fireplaces, wood stoves, window air conditioning units and other heating and cooling systems. Airflow output is on the switch side of the fan. Telescoping housing installs in frame walls from 4 in. to 6-1/2 in. thick. Variable speed fan allows you to adjust the air transferring power to quickly change or maintain temperatures in adjoining rooms. The fan's grille can be painted to match your interior style.
