PTVD
쑺 Perforated diffuser
쑺 Supply
2
Application:
The perforated diffuser type PTVD is suited for supplying
cooled and heated air with a large temperature differential with respect to the room temperature.
The diffuser can be mounted in the ceiling and can be
fitted with a plenum box which can be delivered ready
assembled, including a stabilisation plate. The diffuser
has a removable face plate located on the visible side.
The four in-built pattern blades enable a free choice of
the discharge direction, also after mounting.
Prior to adjustment refer to the performance data. The
high induction effect enables a high number
of air changes. The precise radial pattern minimises
ceiling smudging. The very shallow inflow pattern also
makes the diffuser type PTVD suited for somewhat
lower spaces.
Interface with various ceiling systems is possible, for
detail information contact Solid Air Climate Solutions
sales office.

PTVM
쑺 Perforated diffuser
쑺 Supply
쑺 For Tee-bar mounting
2
Application:
The perforated diffuser type PTVM is suited for supplying cooled and heated air with a large temperature
differential with respect to the room temperature.
The diffuser can be Tee-bar mounted in a ceiling with
a module size of 600 mm and can be fitted with a
plenum box which can be delivered ready assembled,
and includes a stabilisation plate. The perforated diffuser type PTTM is fitted with a 13 mm dropped face
plate. The four in-built pattern blades enable a free
choice of the discharge direction. Prior to adjustment
refer to the performance data.
The high induction effect enables a high number of air
changes. The precise radial pattern minimises ceiling
smudging.
The very shallow inflow pattern also makes the diffuser type PTVM suited for somewhat lower spaces.
Interface with various ceiling systems is possible, for
detail information contact Solid Air Climate Solutions
sales office.

Application:
The perforated diffuser type CTVM is suited for supplying cooled and heated air with a large temperature
differential with respect to the room temperature. The
diffuser can be Tee-bar mounted in a ceiling with a
module size of 600 mm and can be fitted with a bend
or a plenum box.
The high induction effect takes place outside the diffuser and in combination with the precise radial pattern
ceiling smudging is kept at a minimum. The very shallow inflow pattern also makes the diffuser type CTVM
suited for somewhat lower spaces.
Interface with various ceiling systems is possible, for
detail information contact Solid Air Climate Solutions
sales office.

The perforated diffuser type PTVS is suited for supplying cooled and heated air with a large temperature differential with respect to the room temperature.
The diffuser has a removable face plate located on
the visible side, can be Tee-bar mounted in a ceiling
with a 600 mm module size and can be supplied with
a plenum box which is delivered ready assembled and
includes a stabilisation plate.
The four in-built pattern blades enable a free choice of
the spread pattern, also after mounting. Prior to
adjustment refer to the performance data. The high
induction effect enables a high number of air changes.
The precise radial pattern minimises ceiling smudging.
The very shallow inflow pattern also makes the diffuser type PTVS suited for somewhat lower spaces.
Interface with various ceiling systems is possible, for

The perforated diffuser types PSVT and PTVT are suited for supplying cooled and heated air with a large
temperature differential with respect to the room temperature.
The diffuser can be Tee-bar mounted in a ceiling with
a module size of 300 mm and can be fitted with a
(lined) plenum box which is delivered ready assembled
and includes a stabilisation plate.
The type PSVT has a fixed one-way spread pattern.
The PTVT type is equipped with pattern adjusting
blades that enable a free choice of the discharge
direction. Prior to adjustment refer to the performance
data. The very shallow inflow pattern also makes these
diffusers suited for somewhat lower spaces.
The radial pattern minimises ceiling smudging.

PDVM
쑺 Perforated
쑺 Supply, for Tee-bar mounting
쑺 Vertical, down-flow
2
Application:
The down-flow ceiling diffuser type PDVM is suited for
supplying cooled air with a small temperature differential. The diffuser can be Tee-bar mounted in a ceiling.
The diffuser is designed for supply in rooms with a
very high number of air changes such as laboratories
and computer areas.
Since the final velocity of the air in the occupied zone
depends on the temperature differential, the use and
layout of the room must be taken into account when
installing the supply panels.

The velocities given in the table
apply to an isothermal situation
and for separated panels.
The values are to be used as a
reference guideline. The final
velocity of the descending air column is strongly dependent on the
effective differential between the
temperatures of the supply and
room air. Vertical air patterns can
be applied for a high number of air
changes.
The exhaust points should preferably be projected above the heat
source(s).
In case of a difference greater
than 2 K between the room and
supply air temperature the panels
should not be installed directly
above stationary people.
Placement above mobile people
(such as passageways, etc.) and
above unoccupied areas is much
less critical.

• Static pressure drop Ps in Pa.
The assumed room absorption is

LTVD
쑺 Louvre-face diffuser
쑺 Supply
2
Application:
The louvre-face diffuser type LTVD is suited for
supplying cooled and heated air with a large temperature differential with respect to the room temperature.
The diffuser can be mounted in the ceiling and can
be fitted with a plenum box which is delivered ready
assembled and includes a stabilisation plate. The long
throw also ensures good room ventilation for a low
number of air changes.
The choice of five spread patterns enables a great
freedom of placement.
The ceiling diffuser type LTVD has a large capacity,
regardless of the chosen spread pattern. Blanking
plates, to give a 4-way front a 3, 2, or 1 way function
are available.

General:
The pressure drop applies to a fully opened damper.
• throw W in metres.
• static pressure drop Ps in Pa.
The assumed room absorption is 10 dB.
• sound pressure Lp in dB(A).
• Tr is the ambient temperature in oC
• Ts is the supply temperature in oC
Intermediate values may be interpolated.
The throw data in colum ”0” is based on end velocity 0,25 m/s.
The colums with overtemperature give throw data based on the
turning point of the airbeam.

General:
The pressure drop applies to a fully opened damper.
• throw W in metres.
• static pressure drop Ps in Pa.
The assumed room absorption is 10 dB.
• sound pressure Lp in dB(A).
• Tr is the ambient temperature in oC
• Ts is the supply temperature in oC
Intermediate values may be interpolated.
The throw data in colum ”0” is based on end velocity 0,25 m/s.
The colums with overtemperature give throw data based on the
turning point of the airbeam.

The slot diffuser type STBR is suited for supplying
cooled (and heated) air with large temperature differential in relation to the room temperature. The diffuser
can be mounted in the ceiling and easily assembled to
a light fitting with supplied mouting brackets. Two pattern deflector blades (type STA) enable the adjustment
of the discharge air stream, to various configurations.
For linear runs of diffusers that are supplied in multiple
sections, keys are provided to ensure each length of
diffuser aligns with its adjoining section.

Application:
The swirl diffuser type RTBD is suitable for the supply
of cooled air with a large temperature differential and
can be utilised for constant and variable volume installations. The air pattern is fixed. The diffuser may be
used for surface mounting as well as for Tee bar
mounting. The diffuser is for mounting within the ceiling and can be fitted with a plenum box which is delivered ready assembled. The special high induction swirl
effect enables a significant number of air changes. The
very shallow inflow pattern also makes the diffuser
suitable for somewhat lower spaces.

Application:
The swirl diffuser type RTBC is suitable for the supply
of cooled air with a large temperature differential and
can be utilised for constant and variable volume installations. The air pattern is fixed. The diffuser may be
used for surface mounting as well as for Tee bar
mounting. The diffuser is for mounting within the ceiling and can be fitted with a plenum box which is delivered ready assembled. The special high induction swirl
effect enables a significant number of air changes. The
very shallow inflow pattern also makes the diffuser
suitable for somewhat lower spaces.

Application:
The swirl diffuser type RT-C is suitable for the supply
of cooled air with a large temperature differential and
can be utilised for constant and variable volume installations. The air pattern is reversible adjustable: RTGC
or fully adjustable: RTSC. The diffuser may be used for
surface mounting as well as for Tee bar mounting. The
diffuser is for mounting within the ceiling and can be
fitted with a plenum box which is delivered unassembled. The special high induction swirl effect enables a
significant number of air changes. The very shallow
inflow pattern also makes the diffuser suitable for
somewhat lower spaces.

Application:
The round, conic Swirl diffuser type RTWK is suitable
for the supply of cooled or heated air with a big temperature difference and is intended for “comfort”
installations. The diffuser can be applied with and
without ceiling influence. The housing consists of a
round metal nozzle body with six swirl blades that can
be manually adjusted with an actuator or with a thermal spring. Any desired supply direction from horizontal to vertical can be set. The large penetration depth
makes it possible to work with a lower air capacity.
