VAV-RS • Rectangular VAV valves

Rectangular
Gruner controller

Datasheet

VAV-RS air flow regulator can be used both for variable and constant flow and, if appropriate, for forced shut-off for both air supply and air exhaust.

Application

Regulating of air volumes to change the temperature or air quality in a room
Control and regulate the supply air flow and exhaust air flow
Airflow range can be set between two set values or as constant airflow

Material

Galvanized steel

Composition

Operating range is between 1 to 10 m/s
Integrated flow measurement with seperate measurement nipples for control and manual measurement
The damper has stable bearings made of nylon and its shaft is mounted in maintenance free nylon headings
Blade non-air tightness class 2 in accordance with EN1751:1998 in closed position
Manual measurement of the air flow can be performed without disturbing the control circuit via a separate pressure outlet on the orifice plate of the flow variator
All duct connections have spigot dimensions and are equipped with sealing rings made of rubber

Controls

Controller HS25 of 5Nm is a pressure regulated actuator for pressure independent control and with a digital display which enables monitoring the airflow and setting up values without external equipment
Operating range 0-10V or 2-10V (Standard set on 0-10V)
A simple scewdriver can adjust the settings on site
Units of airflow: l/s or m³/h
Minimum adjustable air volume set at air velocity at 1m/s and maximum adjustable airvolume set at air velocity of 10m/s
Running time over the full actuator range : 100s
Power consumption 2.5W, 4.0VA
Supply voltage 24V AC/DC

Options

Insulated version available upon request

Accessories

Sound attenuator, type BTC
