Vent-Axia Lo-Carbon Sentinel Kinetic BH MVHR Unit
Vent-Axia Lo-Carbon Sentinel Kinetic BH MVHR heat recovery unit
The Vent-Axia Lo-Carbon Sentinel Kinetic BH 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: up to ~80 l/s (performance curve)
- Heat recovery: 89–90% (SAP PCDB K+1–K+5)
- Compact – fits a kitchen wall cupboard (290 mm min depth)
- summer bypass & humidity sensor
- spigots reversible on site
The unit measures See datasheet drawing (A–G: 80 / 633 / 501 / 75 / 626 / 447 / 45 mm); fits 290 mm deep kitchen cupboard, weighs 15 kg, has 125 mm duct connections.
Controls: Integral digital controller, humidity sensor, LS/PIR/volt-free inputs, BMS. Filters: ISO Coarse 45% (G3) standard; ePM10 (M5) option. Separate L/R stock refs; spigots can also be reversed on site
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.
