Introduction: Workshop Air Filter
Needing some kind of dust control for the workshop I put together a basic air filter using a cheap fan and a couple of air filters.
Step 1: The Fan
The fan came from a cheap Argos pedestal fan. The fan blade sits quite some distance away from the motor body so I shortened the length of the shaft by moving the rotor down and trimming off the excess shaft.
This means that the overall depth of the unit can be a lot less.
The fan was then mounted onto two pieces of wood, this was done using the original mounting points that attached the motor body to its plastic housing.
The original fan controls were retained so they could be mounted into the case.
Step 2: The Enclosure
The enclosure is a simple frame made from thin plywood, the corners are reinforced with some wooden blocks and everything is glued together.
The buttons from the fan are mounted in the side of the case so it can be easily operated.
The original fan grill was attached over a hole in the front, this was done by drilling holes in the metal frame and attaching it with some wood screws.
Step 3: The Air Filters
For the air filter I am using a commercial unit for a JET air filter. The design is setup to accomodate one or two filters depending on what's needed. If only one filter is in place some wooden spacers fit in the sides.
Step 4: The Finished Unit
We have a be nice policy.
Please be positive and constructive.
