Kair™ ‘Hybrid ’ Heat Recovery Systems consist of individual
ventilators of varying designs and performance, which, when combined,
create dramatic improvements in the quality of the indoor environment.
These ‘tailor made’ systems provide continuous ventilation and are
guaranteed to totally eradicate condensation and mould growth problems
from any dwelling, no matter the size, the design layout, the number of
occupants or how varied the individual’s lifestyle.
Unlike conventional Whole House Heat Recovery Systems, Kair™ ‘Hybrid’
Heat Recovery Systems do not require long runs of unsightly ducting and
help maintain the aesthetics of the dwelling.
These unique systems can be fitted with a variety of sensors, filters
and controls to suit every requirement from condensation control to ‘air
quality assurance’ and can be recalibrated to take into account
increases or changes in occupancy or lifestyle. They can be supplied and
installed with up to 10 years service and maintenance included and
be upgraded as and when necessary or when new technology becomes
available.
Unlike conventional extractor fans which suck out and waste expensively
produced heat, Kair™ ‘Hybrid’ Heat Recovery Systems recover up to
86% of exhaust heat, even when operating on boost mode.
The world is becoming increasingly aware of the enormous cost of energy
production, and this, plus the use of fossil fuels to generate power, is a
momentous environmental issue.
Extractor fans potentially waste over a million kilowatts of energy
every year. This is comparable to the total output of two large power
stations. Replacing conventional extractor fans with heat recovery systems
could save at least half of that energy loss.
As long ago as 1989, an article in the
British Medical Journal referred to the
health hazards associated with condensation
and mould growth in dwellings. The
Statutory Fitness Standard clearly states that
dwellings with inadequate ventilation,
condensation and mould growth problems are unfit for human habitation and
Building Regulation guidelines require a
supply of fresh air and the removal of
pollutants.
D.E.T.R Good Practice Note 268 (Energy
Efficient Ventilation in Housing)
recommends a continuous air change of 0.5
to 1.0 per hour, throughout the entire
dwelling, and this is best achieved by using
mechanical ventilators.
Kair™ ‘Hybrid’ Heat Recovery Systems, by
reducing humidity to optimum levels (Kair
Health Line™), eradicate condensation,
prohibit mould growth and discourage the
spread of bacteria, viruses and dust mite
activity. By expelling dust particles, gasses and other household
pollutants, the units create a dramatic improvement in the quality of the
indoor air supply.
Energy saving with a Health dividend.

Kair™ ‘Hybrid’ Heat Recovery Systems
provide a continuous air change throughout the dwelling, replacing stale
moisture-laden unhealthy air with filtered, fresh, warmed air from outside
the dwelling.
The continuous controlling of Relative
Humidity levels ensures that conditions will not exist in which
condensation or mould growth problems can develop and thrive.
A range of controls are available:
a) Two or four speed Independent switches.
For input or extract motors to create
increased positive or negative pressures.
Ranging from 200m 3 /h to 725m 3 /h.
b) Humidity sensor – two speed trickle /
boost
Isolated humidity controls (preset or
adjustable). SELV control, pull cord and
switch overrides and thermostatic controls
Kair™ ‘Hybrid’ Systems are designed for
easy installation, require minimal runs of
ducting and require little or no external
access. Larger units can be fitted in
cupboards, roof spaces, garages, utility
rooms etc. or ‘boxed in’ to help maintain
the aesthetics of the dwelling.
Installation is undertaken entirely within a
building with no requirement for external
access, thus reducing installation costs on high-rise applications.
All the equipment used in Kair™ ‘Hybrid’
Systems is factory set to provide a positive pressure facility to combat
the ingress of radon gas and increase heat exchange efficiency.
Full installation instructions are provided
with the systems.
Please see separate specification clause leaflet.
Filters should be removed at 6 to 12 month intervals subject to site
conditions and replaced or cleaned with a domestic vacuum cleaner or
washed if exceptionally dirty.
The motors are guaranteed for 5 years and are fitted with ‘Sealed for
Life’ bearings, which do not require maintenance or lubrication.
Kair™ ‘Hybrid’ Heat Recovery
Systems can be serviced and maintained
from inside the building with no
requirement for external access.
Installation can be carried out by a suitably qualified craftsman and
connected to electrical supply by an electrician in accordance with IEE
Regulations.
Kair™ ‘Hybrid’ Heat Recovery Systems Meet current Building
Regulations and ‘Statutory Fitness Standards’ requirements.

Ventilation is necessary to maintain a healthy and comfortable internal
environment and to rapidly remove pollutants such as moisture, volatile
organic compounds (VOC’s), allergens such as dust, oxides of nitrogen,
carbon monoxide, carbon dioxide, tobacco smoke and unpleasant odours.
Moisture is generally assumed to be the most significant of these
pollutants because of the high rates of generation, i.e. cooking, bathing,
washing, drying etc and the consequential condensation and mould growth
problems. It follows that if the ventilation strategy is based on
controlling this principle pollutant by heat recovery input / extract
ventilation then logically the other indoor pollutants will also be
adequately controlled.
Good ventilation means providing a balance between energy efficient and
healthy indoor air best summed up by the catchphrase ‘build tight –
ventilate right’.
The fresh air supply rate should not normally fall below 5 to 8 l/s per
occupant. This is best achieved by creating continuous air changes of 0.5
to 1.0 every hour, throughout the entire dwelling, as specified in D.E.T.R
Good Practice Note 268.
Stale air and air which is hot or humid should be replaced at a
reasonable rate.
Although Building Regulations relate to new buildings, the guidance on
ventilation is applicable to existing dwellings and most important of all,
the regulations are concerned with minimising the risk to health from the
build up of pollutants. Kair™ ‘Hybrid’ Heat Recovery Systems satisfy
all of these criteria.
