OpenAire™ Flow Regulator
The OpenAire™ Flow Regulator simplifies the task of adjusting the supply flow through a bank of CBR filter housings. It installs in place of the CBR filters and simulates their pressure drop over a range of anticipated flow restrictions (5.0 to 7.5 in wg).
A rotary hub opens a series of calibrated flow holes, allowing the user to "dial in" the desired flow resistance. The Flow Regulator cannot be fully closed to allow air to flow through the fan. The Flow Regulator is designed to work with 600-cfm (3 deep) U.S. Navy and OpenAire™ filter housings.
