Rectangular CAV terminals | NN type Double wall construction | System powered mechanical regulator

Rectangular CAV terminals | NN type

Rectangular, constant volume terminals with system powered mechanical regulator NN type, are designed to keep a constant air flow, independent of the inlet static pressure without the use of a DDC CAV/VAV controller/ actuator.

Productspecifications

  • Double wall construction.
  • Pressure independent.
  • Control accuracy ±10%.
  • Factory set, saves commissioning time.
  • Provision for on-site adjustment across the full volume scale.
  • Optional: sound attenuator and / or reheat coil (hot water or electric).

Application

Rectangular, constant volume terminals with system powered mechanical regulator are designed to keep a constant air flow, independent of the inlet static pressure without the use of a DDC CAV/VAV controller/ actuator. These terminals save commissioning time on site and are suitable either for  supply or return air in new or refurbishment projects. Casing leakage rate to Class II VDI 3803 or DIN 24 194. Duct-sleeve connections at the in and outlet are suitable for DIN 24 145 or DIN 24 146 connections.
