Linear Diffuser
Into Mounting Frame
The CSD mounting frame (CSD-MF) is a base frame which is designed to be
built into a solid ceiling. Once the frame has been installed the CSD is then
inserted into this mounting frame to complete the installation.
The CSD-MF offers a vastly improved alternative to the standard method of
CSD installation. This system will not only save time for all of the contractors
involved (HVAC, ceiling erectors, plasterers etc.) but will also give a much
higher standard of finish than was typically able to be achieved.
Normally ceiling slot diffusers are one of the most difficult supply diffusers
to install into a solid ceiling. During the process of installa­tion it is not
uncommon for both the plasterer and the painter to have to carry out
remedial work to ensure a reasonable standard of finish is achieved. All of
this work is obviously detrimental as it takes time and often damages the
linear diffuser and contributes to the poor overall appearance of the CSD.
The CSD-MF is installed as part of the solid ceiling grid system. This allows
the supply air boots to be installed when there is clear access to the ceiling
space and there is no danger of damaging the high quality finish of the
CSD. When it is time to line the ceiling the ceiling erector has a slot to

Patent Pending
slide the gib or plaster sheet into. Once the plasterer has “stopped” the
ceiling sheets the painter is free to paint the entire ceiling without having
to be concerned with masking the CSD which is not yet in place. When
everything has been finished to the required standard the CSD itself is just
simply pushed up into place to completely conceal the mounting frame.
The CSD-MF has many features designed into it to enable a faultless CSD
installation. The mounting frame is equipped with a flexible edge which
is fastened to the adjacent steel or wooden ceiling battens, whichever is
used. This flexible edge allows for any discrepancies in the ceiling itself.
If the flexible edge does not take up any discrepancies in the ceiling the
solid main section of the frame remains rigid to provide an accurate slot
for CSD. The frame is also designed to accept the gib or plaster sheet
accurately, however if there were discrepancies the plasterer can plaster
out those discrepancies.
With all these features the use of the CSD-MF will not only save time in
installing the CSD but will also result in a much higher standard of finish
for the installation.

Performance Notes
4.N.C. values are based upon horizontal projection from a three metre
active section and a room absorption of 10dB re 10-12 watts.
Vertical projection values are 11dB less than listed.
5.N.C. correction for length:
General Notes on performance charts for single or multi slot linear
diffusers in this section.
1.All pressures are Pa (N/m2).
2.Projection (throw) values in metres are based upon the performance of a
one metre long active section. When only 300mm is active, the values are
0.6 times those shown. For a 3 metre long continuous length, the values
are 1.8 times those shown. See table below:

6.Figures for plenum fed diffusers are for essentially zero inlet velocity. The
velocity profile is relatively uniform for the length of the active section.
7.Figures for adapter fed diffusers take account of the effect of the
adapter and inlet neck on diffuser velocities which tend to be less uniform
and produce a velocity profile of the shape shown in the Velocity-Throw
diagram above. The 0.25m/s isovel generally shows a projection reduction
at the centre of approximately 25%.

The same basic extruded design as LD-600 Linear Dif­fuser except
that the 3.2mm x 16mm fixed bar-type louvers are spaced on
12.5mm centres.
Ideal for applications where greater capacity is needed and more free area
is desired.
Use as supply or return. Equally efficient for heating, cooling, ventilating.
The LD 1200 is available with alternate frame types, refer to page 47B.

The same basic extruded design as LD-615 Linear Dif­fuser except that the
3.2mm x 16mm fixed bar-type louvers are spaced on 12.5mm centres.
The wider spaced louvers make this diffuser ideal on applications where
greater capacity is needed and more free area is desired.
Use as supply or return. Equally efficient for heating, cooling, ventilating.
The LD 1215 is available with alternate frame types, refer to page 47B.
When used with the PMF System, see notes on page 62B.

Series LD – Floor Grilles
Modular Floor Grilles
Modular Floor Grilles are available with parallel or cruciform mullions,
using 115 x 115mm square LD or LDH – removeable core elements.

Sizing Parameters
D = Nominal Duct Size
A = Actual Neck Size
N = Number of Core Elements
D
D
D = N x 120 + 20
A = N x 120 + 3
e.g. 2 x 120 = 240 + 20 = 260 Nominal Duct
2 x 120 = 240 + 3 = 243 Actual Neck
Cores may be O degrees or offset 15 degrees to achieve a range of
discharge patterns.
Construction is of Style 2 or 7 outer Frame with core and mullion as
applicable.
D
D
Model LDH-CF Computer Floor Grille
Heavy extruded aluminium construction with double mullion support
bars notched at each blade intersection. The assembly is compressed
mechanically to form a powerful bond between blades and mullions.
Vertical throw units have been independently tested to 500kg
concentrated load on an area of 645mm2 (1 square inch) at the centre.
Deflection under load is 0.66mm and there is no permanent deflection.
Units are also available with 15° air divergence left, centre 0° and 15°
right, in equal sections, to provide a wider spread of discharge air, and
a reduction of approximately 20% of rated throw.
Grilles are manufactured in standard 600 x 600 modules, 32 mm thick
and are designed to replace any standard floor tile. They are compatible
with most computer floor systems.
For Special Size, Thickness and Discharge applications, refer to your
local Holyoake Branch.

Series PMF
Flangeless Grille Series
Linear Diffusers
The Holyoake Flangeless Grille Series - PMF, has been
developed to keep pace with contemporary interior
designs.
The Series PMF is versatile and can be used with all
LD Series Linear Bar Grilles.
Designed for sidewall applications* the Grille
Series – PMF offers a new approach to interior air
supply/return.
For supply and return applications, the Holyoake
Series PMF Flangeless Frame Grilles are the least
intrusive sidewall supply or return air product on the
market.
Framing
Plenum / Duct
Acoustic Insulation
Construction
Constructed from extruded aluminium to precise
Holyoake quality standards, the Holyoake PMF Plaster
Mounting Frame makes flangeless grille installation
easy and provides a superior finish.
Flangeless Linear Grille
Installation
The PMF plaster mounting frame negates the need for
any costly additional aperture framing or nogging and
is fitted into the wall or bulkhead cavity prior to the
wall lining being applied.
The PMF mounting frame can be fitted using rivets,
nails, or adhesive, although drive or Tek screws are
the most efficient method.
A series of grooves in the mounting frame are provided
to prevent screw run-off.
Once the wall lining is in place, the applicator can stop
and finish the wall opening up to the PMF frame edge
and prepare the surface for paint finishes.
The Series - PMF Flangeless Grille need only be fitted
to the complete and finished wall by pushing the grille
into the mounting frame firmly, the retaining clip will
grip the serrations in the frame and pull the grille up
neatly to the wall surface.
* Also suitable for ceiling or floor mounting, with
appropriate construction.
