k14 Question

[divezonescuba]

Hello:

I have acquired a mako/bauer k14. From looking at some parts diagrams, there appears to be an oil filler in the center of the compressor with a upper part secured with 4 clips to the lower half. Inside there is no filter.

Can anyone tell me if this is just an oil filler or if it is also suppose to have an oil filter inside? If not, is there an oil filter somewhere else on the unit?

Thanks.

No oil filter on the K-14. The filler cap is in the center of the stand pipe. the remainder of the standpipe. The piece with the 4 clips is a baffle that directs crankcase air pressure to the intake of the first stage.
To add oil just grap the center cap and pull it off.

Wouldn't it also direct some oil particles into the air intake and into the first stage?

It is also the crank-case breather, so yes some oil transfer occurs. Depending on modification, some K14s did have some what of an oil filter. It wasn't replacable as it was part of tube from the oil pump to the oil pressure regulator. You could remove the tube and blow it out from the reverse flow direction.

The Bauer K14 has 4 manual blow down collectors and what ever air processing filtration you have in line there after, oil mist from the crankcase ventilation is designed to aid in the first stage lubrication and removed out by blow down, so if your still getting any oil in your scuba tank you got bigger problems.

Post a picture of the filter system so we can see what you have. The K-14 has enough air flow (10 -13 CFM) that a small filter chamber may not be enough to provide good air without frequent filter cartridge changes. If we could see the moisture traps and filter chamber, some better solutions might be provided. With a K-14 at least one 30 inch tower would be desired.

Unless added after manufature, there are only two interstage separators on a K14. Bauer does not separate between 1st and 2nd. The final separator is considered part of the filtration system. They did make a kit to add a separator after the 1st stage for extreme high humidity locations.
