#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.

Description :

Connols-Air Linear Slot Diffuser is mainly rated for supply but can be used as return unit or as combination unit as in the case with air-light fixtures. Our linear slot can be easily used with integrated ceiling system with appropriate installation accessory and special frame profile to match the ceiling design. Diffusers are available in 1 to 4 slots and in standard length of 1200 mm with end caps for plaster ceiling installation. For installation on inverted ceiling Tee bar, the diffuser will be constructed of standard 1194 mm length to suit 1200 X 600 mm accessible ceiling system. Standard length diffuser as such are available ex-stock in powder coated standard baked enamel RAL 9010. However longer length up to a maximum of 2400 mm can be custom-made when required. For length, longer than 2400 mm or continuous run linear slot diffuser, they may be formed by joining together 1800mm or 2400 mm diffusers with balance dimensions at each end. Alignment pins and/or bracket may be supplied to ensure straight joints. In addition to straight length diffuser, customised curve shape diffuser with or without acoustic plenum may be available as shown.

Supply air diffuser is supplied with acoustic plenum that is internally lined with fire retardant acoustic foam for better indoor air and sound quality. The acoustic plenum may be supplied with inlet butterfly damper (optional) so that fine airflow balancing with the damper may not increase the generated noise. Acoustic plenum is constructed of galvanised steel of standard length 1200 nominal dimension with one inlet spigot of size 150, 200 or 250 mm diameter. Longer acoustic plenum is available in length of 1800 and 2400 mm and may be provided with one or two inlet spigots depending on the air handling capacity of the linear slot diffuser.

Linear Slot Air Diffuser

Linear slot diffuser of similar number of slot may be used for matching return diffuser. The blade of the diffuser is used for minor airflow balancing. Acoustic plenum may be provided for better noise control.

For installation of diffuser on plaster ceiling great care must be considered during design phase of the project to ensure proper installation can be achieved during construction.

Features

Single Slot Linear Diffusers

  • Frames and blades are constructed of corrosion resistance aluminium alloy and tempered to give rigidity
  • Air Flow pattern setting is easy with dual function blade
  • Flow pattern adjustable to give horizontal one or two-way throw or vertical throw for high ceiling installation
  • Acoustics plenum internally insulated with fire retardant acoustic foam provide noise attenuation and hence ensure lower room noise.
