General description

  • Compact and modular ducted unit, designed for any false ceiling installation
  • Reliable and economical for tertiary building
  • Low height
  • Extremely low sound levels for ducted applications
  • Five- to Six- speed fan AC motors offers a wide choice of medium speeds
  • Available with Low Energy Consumption variable-speed EC motor
  • High-pressure centrifugal fan for 42NH range
  • Factory installed options for fast and easy installation in false ceilings

Configuration flexibility

Each of the 42NL and 42NH sizes can be provided : 
  • With free inlet and/or outlet
  • With a rectangular flange air inlet and/or outlet (practical to connect the fan-coil unit to the air ductwork)
