The flexibility of these diffusers allows installation in a variety of applications to maximize occupant comfort. Linear slot diffusers are available in both straight.
Ventech produce Linear Slot Diffusers from specially drawn aluminium profiles. They are suitable for ceiling and high side-wall applications. Thanks to the connection possibilities of the slot diffusers it is possible to create continuous diffusers in multiple metres and with different corner angles. The two continuous blade type dampers enable to select the throw direction. Upon demand it is possible to mount sliding type volume regulating dampers at the entries of the slot diffusers.
It is also possible to produce the slot diffusers with plenum boxes. The plenum boxes are produced with side entries only, insulated or uninsulated in accordance with customer’s demand. Standard colors of the diffusers are white and other colors are also possible upon customer’s request.
Features:
- Made of high quality extruded aluminium profile
- Designed for variable air volume systems
- The directions and volume of the discharge air can be adjusted by moving the pattern controllers
- Full 180 ° pattern controller adjustment means there is no left or right, specifying ordering and installing are simplified
- Multiple sections are provided with alignment accessories to provide superior, positive field alignment
- Size manufactured on request
- Up to 8 slots available

- The diffuser is located along the longitudinal axis of the ceiling, next to the wall, in a room of the following size:
![Detail Detail](https://i.pinimg.com/originals/30/2a/ba/302abaa0bd32ff9d7c9697c3c867fc13.png)
- The air jet is adherent (Coanda effect), i.e., the diffuser is mounted flush with the ceiling.
For the selection tables with vertical discharge:
- The diffuser is located in the middle of the ceiling in a square room.
- Positioning for vertical discharge, as non-adhering jet.
- The diffuser length is less than 0.5 times the width of the room and less than 0.5 times the throw.
- The pressure Pt is measured inside the duct upstream of the plenum box.
- The height of the room is 3 ± 0.5m
- The ΔT is equal to -10°C, the temperature difference between the room and the supply air.
- The maximum velocity is 0.25m/s in the occupied zone.
Linear Slot Diffuser Cad Detail
Correction factor for width to length ratio of the room ( applied on both 20 & 25mm ).
Linear Slot Diffuser Detail Diagram
The factor is known as Ca. To calculate, divide the diffuser width less length by the length of the room. This is applicable to linear slot diffusers with lateral discharge. In diffusers with vertical discharge, Ca is equal to 1, since these diffusers have been tested in a square room (A/L =1) .
