T-Series Window Model



T-Series range is fitted with a Vent-Axia M-Tech motor, developed to improve performance and lower running costs, and maintain T-Series' rugged reliability.

A patented speed control pack is simply plugged in one of 3 positions to provide low, medium or boost speed matching the fan performance to the requirements of the installation.

Designed for use in single or double glazing and most types of glass and material up to 32mm thick. Greater thicknesses can be accommodated using extended fixing rod sets. Alternatively, the T-Series range can be used in conjunction with Vent-Axia ventilation accessories in flexible and rigid ducting systems to suit individual requirements. The fan can also be mounted in a fixing plate on walls, in ducts or above ceilings.

Best practise

Sensors and auto mode controllers save energy by only switching the ventilation units on when needed and when the room is occupied. The shutter is electronically controlled by an actuator with a damped action giving quiet operation during instant opening and closing. The interlocking edges of the shutter blades provide maximum backdraught protection. When the ventilating unit is used with a T-Series controller, the shutter can be set open with the fan motor switched Off to provide natural ventilation without the security risk of an open window.

The Size 6 model provides the necessary trickle ventilation control to meet Building Regulation Requirements in domestic applications. This is particularly suited to Scottish Building Regulations Document K2.2 and 2.16.

Suitable for running at any angle. Quiet running, enclosed.

Easy cleaning

Integrated component design allows all parts to be dismantled for cleaning without the use of specialist tools.

Ambient Response Humidity Sensor
The latest self programming electronic On/Off wall mounted humidity sensor which reacts to any rapid increase in humidity and temperature by switching a Vent-Axia fan ‘On’ for rapid removal of moisture laden air, in domestic bathrooms and kitchens. Can be wired into controller "Auto" mode connections. Night time RH increment setback feature suppresses uisance tripping when the humidity level gradually rises as the temperature falls. Features & Benefits:
  • Ambient operating temp range +5°C to +40°C.
  • Changeover relay switch.
