VRF Vent

High accuracy with low pressure loss thanks to LTG’s VenturiControl control principle

The VRFvent volume flow controllers are used to control a constant or variable volume flow in rectangular air ducts of Comfort Air Technology systems independently of the inlet pressure.
A full barrier can also be implemented.
Actuation and control are carried out with external energy, either electrically or pneumatically.
The housing cross-sections match the recommended edge lengths for rectangular air ducts in accordance with DIN EN 1505. This makes it possible to select the largest possible flow cross-section even in cramped installation conditions.

• High control accuracy and significant energy saving potential – flow-optimized two-stage nozzle with minimal pressure loss for high effective pressures even at low air velocities
• Universally suitable for mounting various controller makes/components
• Combination with spring return or high-speed drives possible
• For dynamic (VRFvent) and static measurement (VRFvent-s).
• Easy to adjust: can also be retrofitted on site, damper position can be read from the outside
• Simple installation using flanges with slotted holes (or with sliding cage nuts for insulated version)
