It should be noted that once fitted with the NPA 270 connected to ductwork exhausting air out of the area, the Recirculator II will still return approximately 260 cfm into the room in which it is located. Although this will still provide about 9-10 air changes per hour (ACH) in a moderately sized room, it may be necessary to install a second Recirculator unit for local air treatment to maintain any required higher ACH rates. -
