Building Regulations

All Sentinel Kinetic units are compliant under Part F & L of the 2010 Building Regulations.

Physical Dimensions

Whole House MVHR units are often bulky items which can be difficult to fit through an existing loft hatch. Thanks to their detachable spigots and compact light weight design the Kinetic range are particularly suited to retrofit installations. Please check the installation manual for dimensions.

Multiple application uses

The Sentinel Kinetic High Flow has removable spigots that can be applied horrizontally or vertically allowing it to be wall hung or floor mounted (cupboards, lofts, plant rooms etc.).

Automatic frost protection

All Sentinel Kinetic units feature automatic frost protection. If the outdoor temperature drops below 0C the air intake is disabled and the unit serves as an 'extract only' system until the weather improves.

Summer Bypass

A automatic summer bypass is factory fitted as standard for the Sentinel Kinetic High Flow. If the outdoor air temperature exceeds the indoor air temperature the heat recovery function is automatically disabled. Under these conditions the unit provides fresh filtered air throughout the property to help reach a pre- set "Comfort Temperature". When the inside air temperature reaches the "Comfort Temperature" the summer bypass is deactivated.

Integral Humidity Sensor

The integral humidity sensor increases 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 setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature.


The Sentinel Kinetic models have 2 fully adjustable air flow speeds and a purge setting -maximum. On the front of the unit is a digital controller that can be used to pre-set the speeds to any required air flow within the performance range. These settings can be activated on the unit itself or via a wired/wireless remote. This allows for a simple and accurate commisioning in addition to user-friendly controls. The front panel can be removed and fixed onto the rear allowing for flexibility in where the unit can be situated, exhaust spigots closer to the exterior terminals. Solarcrest provide a nationwide supply, installation and commissioning service with BPEC certified installers. We also provide commissioning only, required under 2010 regs, if you prefer to install the system yourself. In which case we can provide installation guidance by telephone and email. Don't forget, draughty trickle vents and airbricks will not be necessary with an MVHR.


Unlike many MVHR units the air filters in the Sentinel Kinetic range range only require an annual inspection and clean, normally with a vacuum cleaner. More frequent inspection post- building work is prudent as the filters are likely to pick up more dust than normal. The Sentinel Kinetic range has a unique filter design that can be easily removed from the front panel (even within restricated spaces) and can be upgraded to F5 pollen filters if you suffer from hay fever. Other than the filter inspection the MVHR is a fit and forget item. All Vent- Axia units come with a 5 year warranty for added peace of mind


Solarcrest will assess your floor plans and ventilation requirements in order to recommend the most appropriate MVHR system. We'll then provide accurate budget costs for the supply, installation and/or commissioning of the system to current building regs. Subject to an initial deposit we release our proposed ducting design and air flow specification for consideration by your building inspector. Subject to approval we can normally have the complete system on site within a week.
