EVVBOR Adjustable valves for supply and extraction air
Description
The EVVBOR series adjustable valves are designed for use in residential mechanical ventilation systems. They are suitable for both supply air and extract air applications and are available in two models with diameters of 80 mm and 125 mm.
Features
The EVVBOR valves are made of white plastic material and can be opened or closed in three steps to increase or decrease the airflow, both in supply and extract applications.
Inside the valve body, deflectors are integrated to direct the airflow in a 2-way air pattern. The valves can also be used without deflectors, thus achieving a 4-way air distribution pattern.
In addition, the valves can be installed in combination with ERDR series constant airflow regulators.
Impiego
Installation can be carried out on any duct with a diameter of 80 mm or 125 mm, ensuring excellent airtightness thanks to the lip seal gasket.
The valve can also be installed on plasterboard false ceilings using the EVMBOR mounting sleeve.
Accessories
- EVMBOR – Sleeve for plasterboard ceiling installation.
- ERDR – Airflow regulator.
