Description
LCFV is a VAV diffuser unit for supply air with circular unperforated face plate for free hanging installations.
LCFV includes a unique linear cone damper with integrated
volume flow regulator used for VAV regulation directly in the
unit.
The built-in VAV actuator is delivered pre-programmed with
damper characteristic and in combination with a stable flow
measurement over the damper, it makes the VAV regulation
very accurate and reliable.
