Variable air volume box equipped with electronic Belimo (LMV-D2 MP) controller, built-in aluminium pressure sensor and integrated silencer

Internal insulation is standard

Available in 7 sizes

• The terminal boxes are designed for single duct high velocity constant or variable flow rate applications and can be used both in supply and exhaust
• Designed for flow rates from 75 up to 6000 m³/h

• The air flow rate control is pressure independent and achieved by a precision engineered damper which modulates in response to a differential pressure sensor and a motorised electronic velocity control device

• Direct communication is possible between the VAV boxes and the central control area

• The volume control and the complete shut-off of the VAV box are obtained by the same damper

• Taking into account the reduced pressure loss in the damper, the boxes need a minimum of inlet pressure which results in remarkable savings in the total energy requirements

• Casing in galvanised steel sheet

• Internal accoustic and thermal gassfibre insulation, coated to prevent erosion
• Air flow control damper in extruded aluminium with keyed shaft; internal pivot points have lubricant-free bearings
• Differential pressure sensor in aluminium; connection sensor-controller by plastic tubes

• Casing air leakage rate complies with:

  - DIN V 24194 Teil 2 class III

  - EN NBN 1751 class A&B

  - EN13779 and NBN 12237 class A&B

  - specifications 105 of 1990 class A&B

• Each VAV box is equipped with an electronic velocity regulator and motor; together with the pressure differential sensor it guarantees a pressure independent variable or constant air flow
• All controls are mounted externally for easy access
• Motor: Belimo Compact LMV-D2 MP

    - power supply: 24 VAC/DC

    - control signal 0-10 VDC/2-10 VDC

    - integrated regulator

    - min.and max. air flow rates (VAV) to indicate by order; on site adjustment possible

    - in case of constant flow rate control (CAV), indicate requested constant flow rate

• Optionally, a heat exchanger can be mounted on the box outlet
