All plenums can now be ordered with factory-installed 1/2″ acoustical insulation and 2″ R6 thermal insulation in order to ensure optimal performance.
PERFAIR plenums, normally featuring a standard perforated damper/air equalizer, are now also available with various models of cable-operated dampers.
MRT is a radial sliding blade cable-operated damper allowing for adjustment through the product’s face. Rotary cable actuation is utilized for damper adjustment, allowing to perform airflow balancing at the face of the diffuser, using a standard 1/4” hex nut driver.
MRT2 is a single blade swivel cable-operated damper with adjustment through the ceiling. It includes a variety of cable termination fixtures designed to accommodate architectural and functional needs. Rotary cable actuation is utilized for damper adjustment, allowing to perform airflow balancing using a standard 1/4” hex nut driver. A 20:1 gear ratio minimizes the torque required to adjust the damper and provides the necessary adjustment resolution for the balancing technician. MRT2 is recommended for products with designs making it difficult to pass a cable thru the face, for instance the PLAY diffusers.
EB is a battery operated, electro-balance damper with remote control and cable thru face. It is a low voltage, battery powered damper system controlled by a hand held remote with a 9V battery. This damper is appealing where jobsite conditions such as distance to the damper, or structural and mechanical systems interference render the installation of an outside the air stream damper system difficult or impossible.
