 Sizes 4", 6", 8", 10", 12", 14", 16", 18", 20", 22"

 Galvanized or 316 stainless

 Slip or flange end fittings

 Control packages including the following:

Offboard Air Module or differential pressure

transmitter.

Required Tools

 Duct tape

 Sealant

 Sheet metal screws

 1/4-inch poly tubing

 Small flat-blade screwdriver

Expected Installation Time

30 minutes

Prerequisites

 Ductwork free of debris

 Construction filters in place

 2-1/2 duct diameters of straight rigid

ductwork upstream of the airflow station. See

Figure 3.



Exhaust ductwork installed

 All wiring must conform to NEC and local

codes and regulations.

NOTE: Airflow stations should be located so that

they do not come in contact with rigid

conduit, sprinkler piping, Greenfield metal

covering, or rigid pneumatic tubing. Do not

install airflow stations tight against concrete

slabs or columns because vibrations are

amplified through these structures. Also,

allow clearance for service access to

controls.
