Description

Designing ventilation systems with the fan mounted in a skylight or a flat roof is easy with T-Series roof models and ventilation accessories. With a low profile cowl, the T-Series roof model is suitable for installation in horizontal, angled and vertical glass and for fixing plates in roofs. For vertical windows or walls in exposed areas and single and double glazing including most types of glass up to 32mm thick. Greater thicknesses can be accommodated using extended fixing rod sets. All four sizes of Vent-Axia roof plate assemblies can be fitted easily into flat roofs.

T-Series features a unique speed control pack which enables high, medium or low speed to be preset to suit room size or required duty. When used with a T-Series TSC controller, the speed control pack is removed from the T-Series ventilating unit and fitted into the 3-pin socket in the back of the controller. The Vent-Axia Ecotronic controller gives even greater running economy with its minimum speed setting and 'E' mode. When using the Ecotronic controller the speed control pack remains in the fan.

Shutter

With energy saving in mind TX models are supplied complete with an integral instantaneous automatic louvre shutter concealed behind the interior grille. It will operate on both intake and extract and at any angle of mounting.

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.

TL models do not have a shutter. They are suitable for systems where no shutter is required or in a ducted system where the shutter is located elsewhere.

Electrical

Motor purpose-designed. Suitable for running at any angle. Quiet running, enclosed. Suitable for operation in ambient temperatures from -40°C to +50°C.

Fitted with self resetting Standard Thermal Overload Protection (S.T.O.P.). Supply voltage 220-240V/1/50 Hz (120V/1/60 Hz).

Easy Cleaning

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

Controllers and Sensors

T-Series Controller Three speeds. Choice of extract/intake Shutter open, fan Off setting Sensor mode. Enables external electro mechanical switches, eg: Ecotronic, HumidiSwitch, ThermoSwitch and TimeSwitch to control the fan.

Ecotronic 130 Controller All the features of T-Series:- Infinitely variable speed control 'E' position for energy saving Minimum speed adjustment.

Ecotronic 400 Controller For groups of units of any one size up to a total of 400 watts. Do not mix T-Series with Standard Range ventilating units on one controller.

Ambient Response Humidity Sensor Self programming electronic On/Off wall mounted humidity sensor which reacts to any rapid increase in humidity and temperature.Night time RH increment setback feature.

Air quality sensor Automatically reacts to the depletion of air quality, sensing tobacco smoke, smells and toilet odours to regulate mechanically ventilated areas.

Ecotronic Humidity Sensor The Ecotronic Humidity Sensor is an adjustable set point, solid state controller. A pullcord provides manual override, indicated by lamp. Adjustable from 65% to 90%RH. Ecotronic includes a relay and can be used with T-Series controller sensor mode.

Performance

Output is for the extract airflow on HIGH.

Technical Data

Typical Specification

Supply and install a T-Series roof fan as manufactured by Vent-Axia Ltd, Fleming Way, Crawley, West Sussex, RH10 9YX, Telephone 01293 526062.

The fan should be suitable for installation in horizontal, angled and vertical glass and for fixing plates in roofs. For vertical glass in exposed areas, and suitable for any types of glass up to 32mm thick. The unit should have the options of fixing rod sets for greater thickness.

The fan should have a speed control pack which enables high, medium and low speed to be set to suit room size or required duty.

The fan should be fully reversible and be able to be controlled by using variable speed controller or by humidity, air quality or PIR sensors.

The fan should incorporate an electronically controlled instantaneous shutter mechanism that has a facility to be in an open state without the fan running for passive ventilation.

The unit should meet with Document F of the Building Regulations and be BEAB approved.

The motor should be suitable to run at any angle and suitable for operation in ambient temperatures from -40°C to +50°C. and should be fitted with self resetting Standard Thermal Overload Protection (S.T.O.P.).
