Okaya RDP Room Damper

Manufacturer: Okaya Seiritsu Engineering Co., Ltd.
Model: RDP

Features

＜Ductless＞
No extensive duct work is required.
Simply install air supply (exhaust) devices in important rooms and mount RDP units on walls between rooms to enable easy stepwise differential pressure control.
＜No adjustment required at the time of installation＞
Simply set the required differential pressure with a remote control.
Adjustment man-hours can be greatly reduced.
＜Visualization of differential pressure＞
Since this product is equipped with a differential pressure gauge, it can monitor the differential pressure between rooms by itself.
In addition, equipped with RS485, centralized monitoring is also possible.
