Vent-Axia Lo-Carbon Multivent MVDC-MS Unit
Product Part Number: 437634
Description
The Vent-Axia Lo-Carbon Multivent MVDC-MS Unit is a high-performance mechanical ventilation unit, designed for homes or commercial spaces that require efficient, low-energy ventilation. Ideal for use in Building ADF (System 3) applications, it provides a range of installation options with wall, ceiling, or loft mounting. This unit ensures improved controllability with variable speed settings, ultra-quiet operation, and is acoustically lined for minimum noise levels.
With a long-life, low-energy multispeed DC motor and best-in-class Specific Fan Power (SFP) of as low as 0.15 w/l/s, the MVDC-MS unit offers outstanding performance while helping to reduce energy consumption. It is also SAP Appendix Q approved, ensuring it meets the latest standards for energy efficiency.
Key Features:
- Variable Speed Settings: Choose from normal or boost speeds for tailored ventilation needs.
- Ultra-Quiet Operation: Acoustically lined casing minimizes noise levels for quiet operation.
- Complies with Building ADF (System 3): Meets the required regulatory standards for residential ventilation systems.
- Flexible Mounting: Option for wall, ceiling, or loft mounting for versatile installation.
- Energy Efficient: Equipped with a long-life, low-energy DC motor, offering best-in-class performance and reduced energy usage.
- SAP Appendix Q Recognized: Approved for use in SAP as part of an energy-efficient solution.
