Product Specification

The Vent-Axia Lo-Carbon Centra 100mm fan is a continuously running extract fan for kitchens, utility rooms, bathrooms and toilets.

The integral digital air velocity sensor will monitor the airflow and maintain the preset extract flow rate of either 6l/s, 9l/s or 15l/s, minimising energy use and noise.

 The Vent-Axia Centra has adjustable ‘Normal’ running speeds making it suitable for continuous extract in kitchens, bathrooms, en-suites and utility areas. This means the developer requires only one fan type for any dwelling.

The 100mm spigot is common with traditional intermittent extract fans, simplifying the specification process.

Safety first – IPX7 rated for installation in bathrooms. Flow rates are safe with open flued appliances.

Switched Live input allows the fan to be boosted by a range of Vent-Axia switches and sensors, or a single light switch.

One fan for all residential applications means a simplified stock profile and repeatable common installations. 6l/s or 9 l/s for normal speed and 15 l/s on boost.

Selection of the two normal flow rates is via a simple ‘jumper’ on the control board.

Can be installed with Vent-Axia range of 110 x 54 flat ducting,100mm circular or flexible duct and accessories for internal room applications.

The attractive and discreet styling of the Vent-Axia Centra will complement the décor of any new home.

Virtually silent operation ensures optimum ventilation is achieved without intrusive noise.

With LoWatt motors energy bills will be reduced - less than 0.5 pence running cost a day.

Long life motors – 5 years warranty means fewer replacements.

Low energy use – LoWatt motors and computer designed impellers means up to 80% savings over traditional motors.

One size fits all – no components to dispose of at installation stage – again reducing wastage.

Plastic components are 100% recyclable.
