Overview
  • Compact and flexible solution for residential extract ventilation, designed for installation inside kitchen cupboards or other indoor positions.
  • Energy-efficient EC motor with stepless 0-10 V control and full speed range.
  • Insulated galvanised steel casing with 30 mm rockwool for low noise operation.


Key benefits
  • Compact footprint for easy installation in confined spaces.
  • Energy savings potential via integrated EC motor and optional demand-control sensors.
  • Low-noise operation thanks to insulated casing and dynamically balanced impeller.
  • Fast maintenance: motor and impeller accessible via removable lid for inspection and cleaning.


Features
  • Casing: galvanised sheet steel, corrosion class C3; 30 mm rockwool thermal and acoustic insulation; fan mounted on removable lid; external cable to terminal box (IP66).
  • Impeller: single-inlet forward-curved radial impeller in glass-fibre reinforced polyamide, dynamically balanced.
  • Motor: high-efficiency external-rotor EC motor for single-phase 50 Hz and 60 Hz supply.
  • Motor protection: integrated electronic thermal protection with locked-rotor protection and soft-start.
  • Control: built-in potentiometer; external control via cooker hoods or controllers with on/off, 3-step or stepless 0-10 V control.
  • Demand control: compatible with external CO2 or relative-humidity (RH%) sensors (accessories) for demand-controlled ventilation.
  • Installation: indoor installation in any position using included mounting brackets; spigots with rubber seals for duct connection; commonly installed inside kitchen cupboards; compatible with recommended cooker hoods.


Applications
  • Compact extract unit for kitchen extraction and general extract ventilation in residential buildings.
  • Suitable where low noise, reduced footprint and energy-efficient ventilation are required.
