Fume Extractor Conversion For Stanley SL18301-4B Wet/Dry Vacuum
Convert your wet/dry vacuum to a fume extractor system for your light duty laser cutter and engraver.
This kit is compatible with the Stanley 4GA vacuum, part number SL18301-4B. It should (but not guaranteed to) also fit numerous other 4HP models of wet/dry shop vacuums as different companies often use the same manufacturer and rebrand their products. See bottom of this listing for other possible models. This modification is fully reversible to return your vacuum back into a regular shop vacuum when not being used as a fume extractor.
Some wet/dry vacuum cleaners offer paper cartridge filters that can be purchased separately from the vacuum unit. However, these paper filters do not filter particles as fine as a proper HEPA filter. Additionally, they do not offer any odor absorption and their availability is often scarce due to their limited use.
This conversion kit will allow you to use a cartridge filter from a popular air purifier system. These readily available replacement filters use both HEPA and activated carbon to filter particles and odors from your laser cutter / engraver. You can simply use paper towels as a pre-filter material to prevent clogging of the HEPA filter and extend its life as seen in the video above. Optionally, you can add extra carbon layers inside to absorb even more odor if necessary.
What is included:
- Plastic Filter Adapters
- CPAP Hose Adapter (Optional)
What is not included:
- Air Filter (Vista 200-RF) (See link below)
- Optional Extra Carbon Filter (See link below)

Below are other 4HP vacuum models that my investigation into the float ball cage assembly leads me to believe this listing is very likely compatible with (but not guaranteed). Models within the same brand (ie. Stanley) likely use the same motor assembly. Various other brands sometimes use the same parts from a common manufacturer and are simply rebranded. Some of them even look identical in every regard minus the logos and colors. Here are some possibilities:
