Bathroom Exhaust Fan Application

How to Perfectly Fit our Drywall Pro X Exhaust in your Bathroom.

Our Drywall Pro X has a dual design - it can be used as an exhaust fan cover or as a cold air return. Complete with a drywall bead rim that contours the vent flush into the surface. Install is best done by a Pro. The Aria Team will focus on the Drywall Pro X's bathroom application with compatible exhaust fans throughout blog. 


Consult an HVAC specialist and electrician prior to installing our Drywall Pro X Exhaust in your bathroom. Installation will require an electrician to complete the electrical connections. An HVAC specialist will be able to determine if our Drywall Pro X will work with your system. 

The Drywall Pro X is compatible with any retrofit fan models that require drywall opening between 8” x 8” to 10 ½” x 10 ½”.

To find if your fan model has the right drywall opening size, check the specification sheet of the fan model. Look for the measurements seen below (circled in red) in Figure 1.1. If those measurements are between 8” x 8” to 10 ½” x 10 ½”, then your exhaust fan will be able to fit within our Drywall Pro X. 

Some popular compatible models are: Panasonic's WhisperCeiling, WhisperFit, WhisperGreen Select. *Always double check the drywall opening - models listed above may have different variations in sizes. 

A special feature of the Drywall Pro X that you may not know is that it can be painted and wallpapered to match your ceiling. We do not recommend tiling or gluing any heavy material to the plate. This will add too much pressure on the plate and prevent the vent clips from fully engaging

The Drywall Pro X is made of powder coated steel, making it compatible with epoxy-based adhesives and paints. However, enamel paints are likely to be more cost-effective. 

Other key features of the Drywall Pro X:

  1. Install at drywall stage: It must be installed at drywalling stage; it is part of our Drywall Line, so it can only be used on drywall surfaces;
  2. Service the fan at any time: access the fan at anytime to clean or service it. Simply slide and remove the cover plate.
  3. No rattling sound: It comes with cushion strips that seal air, and cushions any rattling noise that may occur from the metal components touching. 

Things to look out for:

  1. Extra space in ceiling cavity: You must have an extra 1 3/4" space in the ceiling cavity where the exhaust fan will be installed. (See Figure 1.1). This is recommended in order to allow the Drywall Pro X and exhaust fan to have enough room to fit, avoiding any ceiling joists from impeding the installation. Furthermore, this will allow the Drywall Pro X and exhaust fan to be flush with the ceiling. Below Figure 1.1 and Figure 1.2 highlight this in a diagram and a real life bathroom install.
  2. Check if your fan is compatible: See above for specifications on how to choose the right exhaust fan. 
  3. Dry fit the exhaust fan before installing: Some fans may require the mounting flange on the Drywall Pro X to be trimmed in order for the fan to fit. Double check before mounting. This can be done by dry-fitting the fan into Drywall Pro X opening. Test by sliding the Drywall Pro X's tray. If the fan’s flange obstructs the trays tabs, the flange will need to be trimmed.

We have an installation video of the Drywall Pro X on our YouTube channel.

Here is a rough outline of the installation process for a new build:

1. Frame out an opening (at least 14¼" x 14¼") to accommodate the exhaust fan and vent body.
2. Install the drywall and cut drywall opening at 14¼" x 14¼" for the vent body.
3. Set the vent body into the opening and secure to the framing with drywall screws.
4. Make your electrical and exhaust duct connections.
5. Mount the new exhaust fan. Use cushion strips between touching metal surfaces. *Note: flanges may have to be trimmed to allow for the vent cover tabs to slide into place*
6. Tape and mud around the edges of the vent to make a flush, smooth transition. Slide the cover tray into place.

Most asked questions regarding the Drywall Pro X:

  1. Can I use a motion sensor fan? Yes, you can use motion sensor fans. The Aria Team recommends getting a motion sensor fan that uses a wall switch. This way the center tray of the Drywall Pro X will not impede the motion detection of the exhaust fan. 
  2. What material can this be used with? This vent is specifically for drywall / gypsum wall and ceiling surfaces.
  3. My drywall is already installed, can I use this? Yes, absolutely!
  4. Can I use this on floors, walls and ceilings? This is only for wall and ceiling vents.
  5. Do you make custom sizes or colours? No, sorry about that! This only comes in satin white. It’s ready to be painted or wall-papered to match your walls.
  6. Can my wallpaper completely wrap around the tray? No, this is not possible. It would impede the tray from clamping together.
  7. Where can I find the Airflow data for the Drywall Pro X?  Air returns are measured by open air flow area, not CFM. The open air flow area for our 14"x14" Drywall Pro X: is measures at 32.4 square inches.
