With growing concerns about accurate ventilation of properties, the Lo-Carbon Multivent MVDC range offers the option of ‘Close Control’ both in the residential and the commercial sectors. With a DC motor the multi speed Lo-Carbon Multivent is one of the most efficient central extract units available.

The units have two fully variable speeds for trickle and boost, with a switched live (LS) activation for the boost speed. An additional third speed (purge) is available using a second switched live connection.

An acoustic lining is included as standard, ensuring minimum noise levels.

The potentiometer controlled speed selector allows
accurate setting of airflow, ensuring exactly the right
ventilation rate. This feature also reduces noise, and energy consumption.

Installation
The unit can be installed either horizontally or vertically and where the ambient air has a high humidity content condensate drains are provided.

In support of Multivent MVDC-MS, 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 save energy costs
Rising fuel prices are placing an increasing burden on organisations as they seek to reduce consumption.
- 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

The need to meet legislation
Through the Code for Sustainable Homes Level 3 the UK is designed to deliver a 25% reduction in CO2 levels compared to the 2006 Building Regulations.
- Meets Building Regulations Part F (System 3)
- SAP Appendix Q listed up to kitchen + 6 wet rooms
- Meets carbon footprint reduction targets
- Lowest SFP figures of any demand control MEV system

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 better living environment.
- The integral humidity sensor 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 increase with falling temperature
- Acoustically lined - low noise levels only 18.1 dB(A) @3m

Lo-Carbon Multivent MVDC-MSH
The Multivent continuous mechanical extract ventilation range is designed for the simultaneous ventilation of separate areas in the home or as a multi-point extractor system for a wide range of commercial applications. With a DC motor the Multispeed Multivent is one of the most efficient central extract units in the UK. The Multivent MVDC MSH offers the option of ‘Close Control’ both in the residential and the commercial sectors with the added benefit of an inbuilt humidistat. The unit has 2 fully variable speeds for trickle and boost, with an inbuilt humidistat activation for the boost speed. A switched live (LS) can also be used to select boost speed when wired through an Isolator Relay (Part No. 442030 - not supplied). An additional third speed (purge) is available using a second switched live connection. Extended guarantee to 5 years offered on the MVDC LoWatt energy saving motor.
