DLP High induction linear slot diffuser
The DLP series linear slot diffusers as been designed for the diffusion of air with installation in suspended ceiling. They are suitable for the diffusion of air in room with height between about 2,6 and 4 m or for more height in case of installation near wall or glass wall. They are available in lengths of 500 and 2000 mm with increment of 100 mm from 1 to 6 slot.

The head are available only for the DLPB diffuser... For a better appearance and to give sense of continuity with the 10 mm frame two frame are installed on the short side of the diffuser, (H-DLP...).
The closing cup for the DLP diffuser must be used when the diffuser is installed without a plenum only with appearance purpose for avoid air passages between the room and the suspended ceiling (TC-DLP).

DLP Linear slot diffuser
Technical dataWork ing p r i nc ip l e
The inductive effect, generated by the high inlet air velocity, ensure a rapid decrease of the air velocity itself and at the same time an high temperature uniformities.The inlet angle, respect to the ceiling, ensure the ceiling effect moreover thanks to the stability of the air throw it is possible to reduce the air flow rate till about 40%.The geometry of the deflector is designed to reduce the pressure lost and the noise generated by the veloc-ity inlet.Normally the deflector are supplied with a single way length orientation independently of the number of the number of slot and of the deflector length, different configuration must be requested.The orientation can be easily modified, even when the deflector are installed, by extracting the plastic deflector and rotating them in the desiderate direction. Effective outlet area and noise generation do not change by changing deflector position.The number of the position of the standard connection of the plenum boxes , available with horizontal configuration (standard) or vertical configuration (on demand), provide a uniform distribution of air on all diffusers slot.Sliding dumper can be installed to precisely control the air flow across the diffuser. Depending by the deflec-tor position and orientation different type of throw can be obtained, here some example:
One way horizontal throw
Horizontal throw in opposite direction
Vertical throw near glass wall/wall
Vertical throw in the center of the room
Cons t ruc t i on
The DLP series linear diffusers has got black or white plastic deflector, with support, and frame if present, in natural anodized aluminium. The plenum box made of sendzimir zinc plated steel. In the insolated version the insulated material is certified in class 1 (D.M. 26-06-1984 art. 8). The plenum box connection is made by aluminium. The frame, if present, can be painted with all RAL colours.

E f fec t i ve ou t l e t a rea S (m 2)The effective outlet area is a notional area that, once the velocity of the air is know, makes it possible to arrive at the rate of flow that actually passing through the diffuser. The measurement is carried out with an instrument that measures the air at various pint across the diffuser. The formula links the various parameter is as follow. Q = vk x S x 3600where
Q = supply air flow rate [m3/h]
vk = velocity relating to the effective outlet area S [m/s]

In order to correctly use the chart in the following pages, one must correct them to fit the right installation configuration by using some coefficient depending to the installation configuration itself.
Using single slot linear diffusers, in order to obtain a two way throw is necessary alternate the direction of the deflector every 200 mm .

• For the throw of multiple slot diffuser and for the two way throw the values of L0,2 must be multiply for the corrector factor of the table in page 9.
• The chart of the horizontal throw for the flush with the ceiling installation can be utilized for wall installa-tion at a distance less then 300 mm from the ceiling

M6 female threaded inserts
The installation of the DLP must be carried out as shown in figure, on all our plenum boxes we install four M6 female threaded insert to hang up to the ceiling using threaded bar.

Connection Plate
The connection plate is supplied to allow mounting two or more diffuser in line. It must be placed in the right position as show in the figure above. In the center of the connection plate there is a protrusion that allow to fix it in the diffuser external profile (C-DLP).
Fixing brackets for without plenum installation
The fixing bracket is supplied when one want to install the DLP diffuser without plenum, on it there are al-ready one, two, three or four holes depending on the number of slot, to fix the suspension threaded bar. The fixing brackets are always supplied for the without ple-num installation.
