Air Vent Technology was founded in 1996 in order to

provide high quality products to the Heating and Venti-

lation market.

Since that date the Company has established a reputa-

tion throughout the UK, undertaking many high profile

contracts . The success of the Company has been, and

remains, attributable to a firm commitment to quality

and customer care. Commitment to quality was rein-

forced in 2001 by the introduction of the ISO9001 qual-

ity management system.

In 2007 AVT was brought under the Vectaire Group of

Companies and has since benefitted from over thirty

years' experience in the air movement industry, to-

gether with an innovative approach to product devel-

opment (with particular regard to energy efficient

products which have a high performance/energy ratio).

AVT aims to supply ventilation solutions which

provide the best in energy efficiency, comfort and

design for every segment of the market, and to en-

sure that its responsibility to the environment is a

prime feature in designs for ventilation schemes.

AVT solutions to ventilation problems also reflect

a proper combination of cost effectiveness and en-

ergy efficiency

AVT's highly trained field sales force covers the

whole of the United Kingdom and can provide

quality local support with technical expertise on

products.

AVT can design ventilation schemes from small to

large providing a total, compatible package, thus

guaranteeing a quality ventilation solution.

All AVT products are designed and produced in the

UK to the highest standards. Ventilation/heat re-

covery/air handling systems can be custom built to

solve any specification requirement whilst comply-

ing with all the latest building regulations.

AVT has now developed a rangeof products specifically intendedto ensure the maximum energysaving efficiency by using EC

motors - infinity®

Tel: 01264 356415 Fax: 01264 337854



The infinity® range has been designed to encompass

a comprehensive range of energy efficient, environmen-

tally friendly and economical products.

infinity® fans all have integral trickle and boost con-

trollers to allow them to run continuously at their most

effective supply/extract capacity. The user can boost to

maximum airflow as and when required by means of a

variety of remote switches

The infinity® range includes cabinet fans, both single

and twin fans, direct drive air handling units with airflows

from 0.001 to 1.57 m3/sec for EHB or LPHW heating,

and direct drive heat recovery units - again for EHB or

LPHW heating delivering up to .93 m3/sec. All of these

models are available for internal or external installation

AVT can supply a complete range of accessories includ-

ing silencers, attenuators, pressure switches, filters, anti-

vibration mounts etc, as well as step control panels and

electric heater batteries.

To complete the infinity® rangeAVT has developed a series of lowprofile, direct drive, heat recoveryunits. These products have all the

benefits of others in the infinity®range, but have the added advan-tage of having a maximum profileof only 350mm allowing heat re-covery units to be installed in thetightest of spaces.

The infinity® range allows compliance with all the lat-

est building regulations, and in particular are ErP Direc-

tive 2013 and 2015 Compliant. Every unit is built in

the UK using the latest technology and with EC motors

for the ultimate in energy saving and low specific fan

powers

All models are super quiet with high performance

acoustic linings.

• 7 sizes

• super quiet - high performance acoustic lining

• integral trickle and boost, and isolator

• airflow 3.5 m3/sec

• internal model cabinets from 0.9mm to 1.6mm thick gal-

vanised sheet steel lined with 25mm Barafoam"O" class

6mm barrier mat layer. External models with plastisol finish

• auto reset, thermal cut-out protection

• twin fan versions incorporate an integral auto-

changeover panel and backdraught shutters to prevent

circulation through un-used fan

• integral mounting points for easy installation

• units may be mounted vertically or horizontally with either

top or bottom access

• fan blades statically and dynamically balanced in accordance

with ISO 1940/1 and balancing quality G6.3

• motor/impellor assembly mounted on removable plate

for easy maintenance and cleaning

• motors are pre-wired to an external terminal box, speed

controller and isolator to ensure simple and quick installation

• external models discharge is via birdmesh protected cowl

• max air temperature 40ºC

• powder coating for externally mounted filter boxes is

available (Model No: FUV.../WP etc)

• single phase (450 and 560 models are 3-phase), 230v

• manufactured in UK to ISO 9001

energy efficient, environmentally friendly, economical

EC motors - ErP 2013 and 2015 Compliant

0-10v Closed Loop Pressure Controller

This unit is a PI controller for use with EC fans for

maintaining constant pressure control. When it is

used with an appropriate differential pressure

sensor, it maintains the pre-programmed pressure

in ventilation systems by varying the fan speed in

relation to the system pressure.

Grilles

These grilles can incorporate a wide variety of

functions. With various activation modes such as

humidity, PIR, CO2 and VOC, the grilles can auto-

matically adjust the level of ventilation according to

the needs of the occupants. The airflow range can

be set at installation to adapt to special require-

ments, or to compensate for lack of pressure.

Commissioning is also facilitated by the presence

of an integrated pressure plug allowing connection

to a manometer.

In-Line Damper

In-line opposed blade dampers are available in a

variety of sizes to suit the application. Dampers

come with pre-fitted damper actuators. The

damper actuators can be activated through a vari-

ety of sensors, including, but not limited to, the an-

cillaries listed on the next page. These dampers can

be used in conjunction with the grilles shown above

to create a complete system solution.

Dynamic Remote Humidistat

This unit can be connected to an "Infinity" product

so that it will automatically switch on when the

percentage of humidity in the room reaches the

(adjustable) pre-set level. The unit will continue to

operate until the level of humidity falls below the

pre-set level.

Remote Passive Infra Red



sensor detects the presence of a person in the

room. The unit incorporates an over-run timer and

will continue operating the fan for a (adjustable)

pre-set length of time after the person has moved

away from the range of the sensor.

Thermostat



temperature reaches the (adjustable) pre-set level.

It will then continue to operate until the tempera-

ture falls back to that level.

Air Quality Sensor



sensor detects that the level of pollution has

reached an unacceptable level (pre-set by the user).

The product will then continue to operate until the

pollution has been cleared and the atmosphere

reaches an acceptable level. The AQS incorporates

a switch for manual operation.
