The device uses an high pressure axial fan to pull contaminated air (soldering smoke, 3D printing smoke, etc.) from a work area and blow it through a filter. The filter holder is designed to hold a pleat in sheet filter media (cloth or other) to increase the surface area and reduce resistance.
The fan is attached to the filter holder and tubing manifold by 4 screws.
The tubes can be extended and positioned as needed but a manifold and stand are provided if they work for your application.
The fan/filter holder can also be mounted directly to a cover for a 3D printer or such.
