Following my trip down the compressor moisture rabbit hole I bought one of these Big Gold Bar steward (BGB) filters the other day, direct from Aliexpress for £53.38 delivered. They are huge, I did know that because I bought one of the Big Blue Bar steward (BBB) when they were £18 on ebay. The BGB and BBB have the same external dimensions I think. I no longer own the BBB because it was far to large my needs at the time so I sold it on AGF1. The BGB has longer cap threads and the inner tube fittiing is a better design in my ill informed opinion.
I have done some measuring up and calculations. The inner tube volume is 111cc, the air gap volume between the inner tube and the outer tube is 26cc.
The inner diameter of the inner tube is 26mm so the 20mm diameter cotton filters don't fit.
Mine is filled with 3A molecular sieve with about 10mm of self indicating silica beads at the top so I can see when to change the sieve.
Here's my old BBB for comparison
