#1Q: What is the CFMs I can get from this unit? Thank you
A: Depends on the size you are looking at and the fan pushing the air. Here is the performance sheet for these (CFM vs pressure drop): https://www.hvacquick.com/catalog_files/TRUaire_LD_Performance.pdf

#2Q: I am making the boxes the slot diffuser will slip into, how will the diffusers be secured in place? Should we put a flange on the box?
A: Slot diffusers boxes have a flange (bent upwards, almost hemmed) on the long sides. The Truaire slots come with the C brackets that slip into the bent flages and lock in. The diffusers are secured by screwing through the slots into the C bracket. The holes are pre-drilled in the diffusers.

#3Q: Dear Sales@ HVACIm interested in the TRUaire LD Linear Slot Dff., however even though my choice length is 24, i cannot figure out how to select the width of 6.
A: What you see on the page are the only sizes available. Truaire does not offer other width sizes.

#4Q: is there a way to connect this to a 4 opening ceiling fan duct?
A: You would need a metal plenum that converts the rectangular shape to round. The round outlet is typically on the side of the plenum (box) since the top is narrow. We do not sell them, but you can buy plenums for linear diffuses from local sheet metal shops.

#5Q: Is there an adjustable damper inside diffuser?
A: Yes, each slot has 2 movable parts that are used to adjust the airflow.

2 Slot Diffuser

Introduction
Linear slot diffusers are always considered as the most attractive air distribution devices. They are specially designed for ceiling mounting in a wide range of applications in heating, ventilation and air conditioning systems.
At a perfect setting, linear slot diffusers provide a stable pattern of diffusion to produce an optimum performance for both supply and return air in addition to their pleasant appearance.
COSMOS Linear slot diffusers have been developed to satisfy architectural and engineering applications that require a continuous length appearance, aesthetically pleasing design and high engineering performance.
Slot diffuser models SD‐50, SD‐75 and SD‐100 are designed to give a comprehensive and full range of air flow patterns and volumes. Their deflector blades and volume control dampers give a full flexibility in air pattern and volume control. These are fully adjustable from the face of the diffuser.
Single or multiple slot arrangements can provide any combinations of horizontal, vertical or anyintermediate setting of air flow pattern over a full range of 180° adjustment, as each slot is individually adjustable.
Model SD‐50 has slot width of 12.5mm, SD‐75 has slot width of 19mm and SD‐100 has slot width of 25mm. These slot diffusers are used for both supply and return applications.
COSMOS slot diffusers are manufactured in one up to eight slots with a maximum one piece length of 2.5 meters as a standard permitting complete control of flow rate without disturbing the selected air pattern.
Flanges on both sides are supplied on one piece linear slot diffusers, and on one side of end sections of continuous units. Also diffusers are available with mitered corner.
When installed in the ceiling these diffusers provide a horizontal air path that is adjustable through 180° in each slot. One through eight slot diffusers can be adjusted to provide one way or two way air patterns.
A vertical downward pattern can be adjusted from all slots as can a combination horizontal pattern and vertical downward pattern from a two or more slot diffuser.
When installed in a side wall near the ceiling or in a sill, these diffusers can be adjusted to direct the air path upward to the ceiling and then horizontal along the ceiling.

Slot Diffuser Plenum Box
COSMOS plenum box for slot diffuser is designed primarily for ceiling and high sidewall installation, they are eminently suited to, and recommended for, VAV applications. It is also designed to ensure equal distribution of air across the slot diffusers.
They maintain a tight and stable horizontal air pattern over a wide range of air volume by air volumes by utilizing the maximum ceiling coanda effect.
The special mechanism provided with plenum facilitates easy attachment with slot diffuser and eliminates air leakage above falls ceiling. Plenums save on site fabrication and field labor.
Plenum box has acoustic lining to reduce noise generated inside the duct due to airflow turbulence before reaching the diffuser.
COSMOS plenum has three series P12, P19 and P25. Series P12 has plenum with slots having width of 12.5mm, P19 has plenum with slots having width of 19mm and series P25 has plenum with slots having width of 25mm. Series P12‐D, P19‐D and P25‐D comes with damper at the inlet. These series has butterfly damper or spigot damper at the inlet for controlling the volume
of flow. The built in damper can be operated from the spigot connection or from the face of the diffuser.
