Vent-Axia Lo-Carbon Sentinel Kinetic Plus B MVHR Unit
Vent-Axia Lo-Carbon Sentinel Kinetic Plus B MVHR heat recovery unit – up to 400 m³/h
The Vent-Axia Lo-Carbon Sentinel Kinetic Plus B is a UK-designed mechanical ventilation with heat recovery (MVHR) unit from Vent-Axia, giving continuous whole-house ventilation while recovering heat from extracted air.
It is aimed at airtight new-build and retrofit homes.
Key features
- Airflow: 400 m³/h @ 150 Pa
- Heat recovery: 90–91% (SAP PCDB K+1–K+7)
- Up to 400 m³/h at 150 Pa – up to 10 wet rooms + kitchen
- ~90% heat recovery
- folding filter
- acoustic options
- humidistat
The unit measures See datasheet drawing (A–G: 80 / 733 / 501 / 71 / 855 / 583 / 40 mm), weighs 24 kg, has 125 mm (web page); datasheet table lists 150 mm spigot – optional 180/200 mm kit 446523 duct connections.
Controls: Integral digital controller, humidity sensor, LS/PIR/volt-free inputs, BMS. Filters: ISO Coarse 45% (G3) standard; ePM10 (M5) option. Left and right hand units available (separate stock refs)
Every MVHR system should be designed around the dwelling's ventilation rates, with insulated ducting on the outside-air and exhaust runs. We can supply matching ducting, filters and controls. Specifications are taken from the manufacturer's published data.
Supplied by Low Cost Renewables at trade prices, with delivery across the UK and Ireland.
