Vent-Axia 495360 Lo-Carbon Sentinel Multivent HX MVDC Unit

Product Description

The Vent-Axia 495360 Lo-Carbon Sentinel Multivent HX MVDC Unit is an energy-efficient centralised Mechanical Extract Ventilation (MEV) system designed to provide continuous ventilation across multiple rooms. Ideal for new-build homes and suitable multipoint commercial applications, this advanced ventilation unit helps remove moisture, stale air and indoor pollutants to maintain a healthier and more comfortable living environment.

Featuring energy-efficient EC/DC motor technology, the Sentinel Multivent range delivers reliable extraction performance with low energy consumption. With a Specific Fan Power (SFP) as low as 0.16 W/l/s under specified operating conditions, the system helps reduce running costs and supports improved building energy efficiency.

The integrated digital display enables installers to configure low, normal, boost and purge ventilation speeds accurately. Demand-controlled ventilation settings can be adjusted in 1% increments to match property requirements, while manual and automatic control options provide flexibility for different installations.

Designed for straightforward installation and commissioning, the Sentinel Multivent HX can be mounted on a wall, ceiling or within a suitable loft space. Compatible external sensors and controllers allow ventilation performance to be tailored to individual property needs, while the integral adjustable overrun and delay-on timers provide additional control.

Manufactured in the UK and recognised in the SAP Product Characteristics Database (PCDB), the Vent-Axia Sentinel Multivent range provides an effective whole-house extract ventilation solution for modern residential developments.

Energy-Efficient Continuous Extract Ventilation

The Lo-Carbon Sentinel Multivent range uses advanced EC/DC motor technology to deliver effective continuous extraction while reducing energy consumption compared with conventional AC motor designs. Low Specific Fan Power helps minimise electricity usage and contributes to the energy-efficient operation of the ventilation system.

By extracting moisture-laden and polluted air from kitchens, bathrooms, utility rooms and other wet areas, the system helps maintain balanced indoor conditions when combined with appropriate replacement air provision.

Intelligent Digital Controls

The integral digital display simplifies commissioning by allowing installers to configure ventilation speeds according to the requirements of the property. Low, normal, boost and purge settings provide flexible airflow management, while demand-controlled adjustment in 1% increments enables precise system configuration.

Manual and automatic control options, compatible external sensors and adjustable timer functions allow the ventilation system to respond to different occupancy patterns and extraction requirements.

Humidity Control & Indoor Air Quality

The Sentinel Multivent range supports effective moisture management by continuously extracting humid air from wet rooms. The HX model is designed for humidity-responsive ventilation, helping increase extraction when moisture levels rise.

Humidity-sensitive control can help manage condensation and maintain comfortable indoor conditions while avoiding unnecessary high-speed operation. The system also supports the removal of indoor pollutants, including excess carbon dioxide and unwanted odours, through continuous air extraction.

Flexible Installation Options

The Vent-Axia Sentinel Multivent can be installed on a wall, ceiling or within a suitable loft space, providing flexibility for different building layouts. Its centralised extraction design allows multiple rooms to connect to a single ventilation unit.

For projects requiring compact ductwork, the system can be combined with suitable semi-rigid ducting solutions, such as the Vent-Axia Uniflexplus+ range, subject to system design and compatibility.

Condensate drainage provision supports installations where humid air may cause condensation within the ventilation system.

Building Regulations & SAP PCDB

The Sentinel Multivent range is designed to support the ventilation requirements of Building Regulations Approved Document F, including System 3 continuous mechanical extract ventilation. Its energy-efficient performance also supports building energy assessments under Approved Document L.

The range is recognised in the SAP Product Characteristics Database for suitable whole-house ventilation configurations, including applications serving a kitchen and up to six wet rooms. Final system selection and commissioning should follow the applicable regulations and project ventilation calculations.
