Cheap Compressor Filters

Cheap Compressor Filters...
- I've seen these advertised on Ebay and it tweaked my curiosity. I wanted to see for myself:
1. Are they compatible with Lawrence Factor pre-packed filters?
2. Is the moisture condenser tower of decent design/function?
3. Are the towers robust enough for high pressure?
4. So I ordered a set to see for myself.
Lawrence Factor Compatibility...
- The closest thing I found is the Lawrence Factor 15XXX series that fit Coltri MCH-6 filter tubes. These are same diameter but a little too long. I think the LF filter tube can be shortened into a convenient re-packable tube that would fit. On the other hand, the filter that comes with could also be re-packed. There's a difference in the two filters at the O-ring seal. Personally, I would want the filter to be about 2/3rds 13X Sieve and 1/3 carbon.

Moisture Condenser Tower...
- I am particularly interested in the moisture condenser design because I had to make one for my old Coltri MCH-6 and my old Tornado Kidde actually uses aquarium rocks for condensation surface area. I don't know if this design is unique but it looks better than what was in my old MCH-6 as well as what's in the new MaxAir 35. It looks like it keeps incoming condensation better separated from outgoing dry air.
Robust Design/Construction
- The specs say these filtertowers are rated to 300 BAR or 4351 psi.
- They are thick aluminum construction and heavy.
- Dimensionally they are comparable to the MaxAir 35 and Coltri MCH-6 filter towers.
Additional Thoughts/Comments...
- My challenge right now in trying these out is that they have input and output threads of G1/4. I have other plumbing to hook up and will need these to be adapted to 1/4 NPT for pressure switch, OPV, PMV, etc.
- The all carbon filter they come with isn't that shocking... It wasn't all that long ago that MCH-6 filters were all carbon. Some of the other Ebay filters are being offered in 3-part filter materials so I would not be surprised if these get offered that way too.
- Meantime I can either shorten Lawrence factor before use or re-pack.
- These filters have a clever extraction method... The tops are threaded for a bolt. Screw it in and you have a nice big handle to pull out the filter.
