The need for better health

Removal of pollutants, such as moisture, carbon dioxide and external fumes are all important factors in maintaining indoor air quality, helping to create a healthier living environment.

  • The integral humidity sensor (Sentinel Multivent H) increases fan speed in proportion to relative humidity levels, saving energy and reducing noise
  • The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room
  • Night time relative humidity increment setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature
  • Acoustically lined - low noise levels only 18.1 dB(A) @ 3m
