Vent Axia 408451 Lo Carbon Sentinel Kinetic High Flow Left Hand
Shared Accommodation and Multiple Occupancy Heat Recovery Unit


The Sentinel Kinetic Range incorporates:
A wholehouse heat recovery system with up to 92% energy efficiency. An easily accessible heat recovery cube protected by two removable EU3 filters. Two Lo-Carbon Energy Saving EC DC fans ensure long life (typically over double the life of AC motors) and lowest possible energy use. Fully insulated construction with built in condensation drain. Specifically designed for new build constructions with a high level of insulation.

Lo-Carbon Sentinel Kinetic meets the latest requirements of the Building Regulations Document F 2006 for whole house system ventilation: System 4. Continuous mechanical supply and extract with heat recovery. The Lo-Carbon Sentinel Kinetic models have 3 fully adjustable 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.

Multiple control options:
Five Volt-free pairs of switch terminals for sensor inputs allow boosting from a full range of Vent-Axia controllers - humidistats, PIR, timers. Two terminals with 0-24V outputs allow 0V to 10V proportional control by sophisticated controllers such as CO2 sensors and proportional humidistats. The optional Vent-Wise controller senses temperature rise in a bath/shower hot water supply and/or current in a cooker/hob electrical circuit to activate boost, ensuring additional ventilation when needed. Switched-live for boosting via light switches (220-240 V AC) or manual Normal/Boost switches. This connection has the advantage of Delay-On and Delay-Off facility. Delay-On enables you to prevent the Boost airflow between 0 and 10 minutes, after a light switch has been activated. Delay-Off allows the Boost airflow to continue after a light switch is turned off to ensure effective clearance of humidity. This timer is adjustable between 0 and 25 minutes.

Purge setting:
The unit can be set to maximum flow (100%) by pressing and holding the Boost button on the unit itself or optional wireless controller for 5 seconds. Purge will continue for two hours unless cancelled by pressing the Boost button again.

Larger Spigot Diameter:
The Sentinel Kinetic High Flow is fitted with larger 180mm - 200mm spigots to allow for a higher flow of air at 175l/s, allowing it to extract from up to 14 bathrooms and a communal kitchen with ease.

Summer Bypass
An internal damper is activated when the outside temperature is less than the room temperature. The damper opens allowing cooler fresh air to bypass the Heat Recovery Cell and reduce the internal temperature towards the pre-set 'Comfort Temperature'. When the inside air temperature reaches the pre set 'Comfort temperature' the bypass damper closes.
Anti-frost protection: In cold climates there is a possibility of frost building up on the intake side of the heat exchanger. In order to prevent damage, the Kinetic reduces supply flow while maintaining extract flow at temperatures below zero.

Easy Installation
The Sentinel Kinetic models can be mounted vertically in a roof space, and are suitable for wall mounting or within a kitchen cupboard. When mounted in an unheated area ducting should be insulated. Ducting can be attached to the unit horizonally, vertically or both. Minimum internal depth of kitchen cupboard: V&B models 290mm. CW models 300mm V&B Models

Left hand installation.
This unit is only available in left hand configuration and can only be installed that way. A right hand version, the 408449, is available.

Horizontal and vertical spigots:
The combination of spigot options allows installation in confined locations. If vertical and horizontal connection is required on the same outlet/inlet, additional spigots can be supplied. Condensate drain can be taken out through the back, or bottom of the unit. Using the fittings supplied, the final condensate connection is made outside the unit and can be completed after installation.

Minimum 3 Year Warranty on All Fans
