I build custom cabinets for 50's-70's RV; s. I have an older Jet dust collector and I wanted to switch from bags to a canister filter and a cone vortex generator. I discovered that the housing on my machine wasn't configured to work with the canister or the vortex cone so I bought a later model housing from e-replacements and adapted it to mount on my machine. What a difference that made! Now virtually no dust escapes into my shop from the D. C.
