Architectural Selection of Holyoake Products
The CFP Ceiling Fixed Pattern Radial
Swirl Diffuser range is designed
for large, open office spaces and
education facilities where there’s a
need for high-quality air flow.
The CFP Series is designed to blend
unobtrusively into its environment, making
it well suited to commercial locations where
aesthetics are important.
Each diffuser is constructed with swirl deflection blades that produce a highly
turbulent radial airflow pattern, resulting in rapid temperature equalisation and
ensuring a comfortable environment. The CFP diffuser is suitable for use where there
are increased temperature differentials and variable air volumes, as the ceiling effect
is maintained from minimal through to very high air flow rates.
With the CFP Series, the induction swirl pattern produces high room air diffusion
quality. Air is drawn up into the supply air path, mixing at a high level and reducing
the chance of draughts while creating optimum conditions in the space.
Ceiling Radial Induction Swirl Diffusers were selected for the headquarters of the
National Library (left) to blend seamlessly into the contemporary interior design
scheme. The same CFP – with exposed ducting – has been used in Albany Senior
High School as a dramatic design feature (below).

CSS Ceiling Slot Swirl Diffusers have
been designed to provide attractive,
unobtrusive, high-quality indoor air
diffusion.
While good air quality is always a focus in
commercial locations such as restaurants and
hotel lobbies, it is just as critical to consider
the visual environment. Holyoake CSS radial
pattern diffusers are designed to meet both
criteria, and tailormade solutions can be created to meet individual needs.
Made up of slots in a radial angled pattern that produce a circular, swirling airflow,
the CSS achieves high room air diffusion quality due to its swirling motion. Strong
induction draws room air up into the supply air flow path which results in mixing at a
high level, reducing draughts and uneven temperature gradients.
The airflow pattern from the CSS Slot Swirl Diffuser can be adjusted easily via
the diffuser face. By rotating the pattern blades, the airflow can be directed in an
external, internal or vertical air discharge swirl pattern. It can also be used for exhaust
situations.
Ceiling Slot Swirl Diffusers are equally effective when used at a reduced volume,
ensuring uniform temperature gradients. For a clean, uncluttered ceiling appearance,
diffusers are powdercoated to suit individual applications, such as this building lobby
(left) and café (below).

The Ceiling Multi Pattern series of
diffusers is designed to complement
contemporary interiors and provide an
attractive source of air flow.
CMP diffusers are available in multiple blade
patterns that can be customised to blend
into different traditional and contemporary
environments.
The tough aluminium construction of this ceiling diffuser ensures it is rugged and
yet still lightweight and clean-lined in appearance, with precisely mitred corners and
concealed fixings. This time-proven product has been perfected over the years to
look great, and other improvements ensure it offers the best possible performance
and style.
In these two high-end retail environments (left and below) CMP diffusers have been

The FSD Floor Swirl Diffuser is
specifically designed for raised access
floors that conceal air distribution
systems.
Holyoake Industries specialises in diffusion
products where raised floors are part of the
design concept. The circular FSD diffuser,
manufactured in glass-filled polycarbonate, lies
flush with the floor. The hardwearing trim ring
flange secures carpets and prevents the edges
from fraying. An adjustable mounting clamp
adapts to any floor thickness and ensures
installation is simple and secure, and a dust
basket catches anything that might fall through
the diffuser face.
The JD Jet Diffuser provides an
attractive air management option
in large areas such as airports and
shopping malls. A powerful system, it
quickly circulates large volumes of air
throughout big, open spaces.
Jet Diffusers suit applications where substantial supply air flow and throw distances
are required. These versatile diffusers can be switched from jet mode to diffuser
mode by simply turning the core. Constructed from three cones, they provide
uniformity of appearance throughout the range. Jet Diffusers come complete with a
patented mounting system made from spun aluminium which a provides a perfect
finish for both wall and ceiling applications.
The raised access floor in this office space is fitted with a series of Floor Swirl
Diffusers around its perimeter (left). In the application (below), the architect chose to
have three diffusers in close proximity to each other to create a particular visual effect.

The ECO Automatic
Environmental Ceiling
Outlet is a circular
ceiling diffuser with a
clean-lined, understated
appearance that works
well in commercial and
residential applications.
This energy-smart product is designed to heat or cool a space quickly, and it has the
capability to automatically alter a portion of the supply airflow from a horizontal to a
vertical throw, depending on the temperature required.
The ECO Automatic is designed to be very easy to install into new locations. It is also
easy to retrofit, as it can be slotted into the same sized hole as other similar types of
diffusers. A slightly larger diameter on the outer flange will cover any imperfections
in the ceiling finish that may have been left when the original diffuser was removed.
By flush-mounting the diffuser into the ceiling, the finished result is clean and
unobtrusive.
The ECO is constructed from tough UV-stabilised and fire-rated engineering polymer,
which is coloured white. A full range of automatic, manual, round- and square-faced
diffusers are available in several sizes. Visible surfaces have a textured finish.
The energy-efficient ECO Automatic diffuser, finished in white, fits discreetly into
the ceiling of this restaurant (left). It is equally well suited to high-end residential
applications, such as this private home (below).

ensures this diffuser makes a bold statement
wherever it is specified. It is efficient and offers
flexibility of design with an air pattern that can
be adjusted to project air horizontally or vertically.
With a compact, flat trim flange, its appearance
on the ceiling is sharp and modern.
All CRA diffusers have three cones for uniformity
of appearance. In its standard form, the diffuser
is manually adjustable to change the supply air
pattern from a horizontal discharge for cooling
to a vertical angle for heating. With the radial
supply air pattern and the reduced flat trim ring,
the diffuser achieves a better ceiling effect
than standard round ceiling diffusers, making it
suitable for a variety of applications such as retail
locations where a cool, comfortable environment
is important. The CRA and CRP come complete
with a patented installation system.
In this DFS duty-free store (left), the spun
aluminium construction provides a perfect finish, irrespective of the ceiling design. In
