Filter and Fan Modules Completed
Work is progressing nicely on the air brush paint booth. My uncle, Joe Scorsone, has been a big help with this project!
The center wall that forms the angled back of the painting chamber has been installed with the ventilation grill cut in.
The next component is a vertical wall that that houses the air filter. This structure will be mounted permanently behind the paint chamber. It will be sealed around the perimeter forcing all air to flow through the filter.
A reduction chamber module is the next component. This chamber will slide into the rear of the paint booth and will screw into the wall with the filter. This keeps airflow coming out of the filter in a space the same dimensions of the filter as opposed to the dimensions of the paint booth.
The final module houses the exhaust fan itself. This component fits snugly against the reduction chamber so that all air passing through the filter will be pulled into the fan. Like the reduction chamber module this component slides into the rear of the paint booth and screws in place to the reduction chamber module. All holes in the module and the fan housing will be sealed to ensure that all airflow travels from the reduction chamber to the exhaust.
Large notches will be cut into the fan housing module allowing the reduction chamber module to be easily unscrewed from the rear of the paint booth to allow for changing of the air filter.
Next these three structures were assembled together and inserted into the paint booth for a test fit.
They all came together nicely! The paint booth was positioned by n outlet for a test run. With the filter wall not sealed and the fourth wall of the filter held loosely to the rest of the structure the air flow into the vent at the back of the painting chamber was sufficient enough to hold the three full-sized stapled papers with the earlier paint booth drawings firmly to the grill!
There is no doubt now that once the paint booth is painted and sealed there will be sufficient airflow provided by this fan to provide the intended ventilation!
Below for reference is an image of the bottle of glue used to attache the permanent pieces. Tightbond III Ultimate Wood Glue is very strong and will not dissolve once set. So far I have been very impressed with its properties.
Next will be firming up of these components and the overall structure and then some electrical work!
