Homemade spray booth for models

DIY airbrush spray booth / DIY hobby Spray Booth

If you are a professional modeler, if you want to make a high-performance paint booth, this article titled “Homemade spray booth for models” is for you. All you need is some basic tools, common materials, and a few hours to build.

We recently created our own hobby spray booth, which was very good for us, so we prepared this article to show how we do it. Choose your preferred wood type, follow the instructions and start building your spray booth.

Below, we highlight some of the benefits of our hobby spray booth.

DIY airbrush spray booth fan

We chose this Dayton blower because it was quiet and powerful. We’ve done comparison tests of several different blowers and fans, the Dayton 6FHX9 was the quietest, the best performance against static pressure, and the best overall performance from other similar blowers (265 CFM). We also received positive feedback from many readers about their blowers.

We know that Amazon’s retail pricing can be a bit expensive, so if you don’t mind the cost, we recommend you buy this model. If you have chosen to use a different blower and your exhaust pipe is longer than 8 meters in operation, be sure to withstand static pressure similar to the Dayton blower.

Make sure that the key features are as specified in the following table.

This type of blower does not come wired, so you will have to get a grounded power cord and wiring it yourself. This process is extremely simple, literally only 3 wires; 1 positive, 1 negative and 1 ground. Don’t worry, you won’t need any prior knowledge or electrical knowledge to wire the blower.

We used 24 gauge galvanized steel for the fan mounting panel, so that we could only discharge the top or bottom by turning the panel. We installed the blower outside so that the motor windings would not be damaged by harmful paints and solvents.

When we installed the spray booth, we created our own square-round adapter. People started asking us where to buy an adapter, so we started looking for an adapter that would work. After much research, we concluded that there was no commercially available adapter to switch from the blower’s square flange to a round duct outlet. We’ve found that we can add value if we make this adapter commercially available.

Current Information:

We adapted this product we found to our project. We removed the triangular sections in the header of the adapter we bought according to the fan dimensions we will use. The piece we obtained has become suitable for our project. You can buy the square-round adapter here.

This product allows the Dayton Blower 6FHX9 to be ventilated using a standard 4 “inch diameter circular duct. This adapter can be used with rigid, semi-rigid or flexible ducts.

Note: You must bend the flange flush with the blower body for proper alignment of the adapter’s bolt arrangement.

Warning: Flange sizes and bolt patterns may vary and may not match other blowers.

When we created the filter rack for our spray booth, we used 24 carats of galvanized steel, and we realize that most people will not be able to use it. The filter rack can be made of wood, it can be plywood that you use to create the cabinet. If you want to use a different filter, you can browse the options here.

For example, if you use an expensive allergen filter, cheap standard furnace filters work best. Strain the furnace filter, restrict flow and cause insufficient ventilation.

We decided not to include the internal lights in the booth, but instead, we used Plexiglass as the top panel. In this way, the light could easily enter the cabin and we could quickly adjust the light depending on where we are and what we do. We recommend 1/8 “to 1/4” Plexiglass, but you can use any translucent material. Local hardware stores should have something available in stock, but thickness, size, and materials may vary.

We used a table saw to cut the material, but a circular saw will work. Be sure to adjust the depth of the saw blade only to clean the material, otherwise, the material may detach, crack, or saw chip.

The spray booth used in this article is built using a Vent Works Filter Rack and Fan Mounting Panel, but you can also make these parts yourself using wood. If you are using wood for the fan mounting panel, the final process shown in the Mounting the Dayton Blower 6FHX9 to the Fan Mounting Panel video will be the same. You will have to create a panel, cut the hole, drill pilot holes in the panel and fan, and provide proper hardware and air tightness.

Below are images of a cabinet created using the same plywood, filter frame, fan mounting panel, and top panel (instead of Plexiglas) for the cabinet.

Homemade Spraybooth and Filter

An airbrush is a tool that uses compressed air to atomize and apply paint, ink, dyes or other mediums to surfaces. Airbrushes are used in many different applications for both artistic and practical purposes.
If you plan on using an airbrush for painting scale models, you need to take some precautions to ensure a healthy work environment. A spray booth will protect you from inhaling harmful fumes and will also help contain the paint so that it doesn’t end up everywhere but on your model.
A spray booth is not necessary, but it is a good idea if you are going to be doing a lot of airbrushing. They are inexpensive and can be found online or at your local hobby store.

You can make your own spray paint booth very using cardboard and tape. Watch the video we shared in the 2nd or 3rd title.

An airbrush spray booth is a device that helps to control the overspray when using an airbrush. It does this by providing a contained area for the airbrush user to spray their paint in and then vents the fumes out of the room. This containment of the paint and fumes prevents the paint from getting on surfaces that should not be painted and also helps to protect the user from inhaling dangerous fumes.

An airbrush booth is not a requirement for painting your model, but it does have some advantages. The most important advantage is that it significantly reduces the amount of overspray. When you are spraying paint, some of the paint will inevitably end up outside of the booth on your floor, walls, or furniture. An airbrush booth contains the paint inside, so you don’t have to worry about making a mess.

  1. This looks pretty cool. I am used to using old fans from used computer towers, cardboard boxes and 4 inch dryer duct. Something a little more permanent would be cool instead of having to salvage these parts like usual. I may give this a try. Very well done !
