Select a product

Sentinel Multivent continuous mechanical extract ventilation, MEV is designed for the simultaneous ventilation of separate areas in the home or as a multipoint extraction system for a wide range of commercial applications. The units can be wall, ceiling or loft mounted. Where the ambient air has a high humidity content condensate drains are provided.

In support of Sentinel Multivent, Vent-Axia offers:

  • Practical advice on product selection and installation
  • Guidance on solutions to meet legislation requirements
  • Project management and site deliveries
  • After sales support and maintenance information

The need to improve efficiency

Sentinel Multivent has been designed to meet the exacting demands of developers, installers and users offering advanced control options and easier installation and commissioning.

  • Demand Control - enables precise ventilation rate, is set in 1% increments based on property size
  • Comfort mode allows homeowners to control when the unit runs and for how long to avoid disturbance
  • Integral digital display allows the installer to select appropriate low, normal, boost and purge speeds to meet demand
  • Manual and automatic control options
  • Integral adjustable overrun timer and delay on timer
  • Switched live and SELV connections
  • Optional Wireless Control on “X” units
  • Energy efficient EC/DC motors - 1/3 less energy lost to heat than a conventional AC motor
  • Low Specific Fan Power (SFP) making it one of the most efficient products on the market

Legislation

  • Meets Building Regulations Approved Document F (System 3)
  • Recognised in SAP PCDB up to kitchen + 6 wet rooms
  • Meets carbon footprint reduction targets
  • 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
