KUKEN Variable Air Volume Control

VAV is an abbreviation of Variable Air Volume unit.
It is a device to change air volume upon receipt of air-volume signal from moon-thermo or manometer.
With Kuken VAV, precise control of room temp. and room pressure can be done due to the fact that
VAV unit is designed to respond to air volume change by comparing present air volume
(built-in air velocity sensor does reading) to demanded air volume.
In this way, it can cope immediately with sudden pressure change in air duct.
