I have found to be true that laminates look much better with a 10% drop in vacuum level, and have read countless times that pumps do not like pumping untill the vacuum has reached a certain level due to expansion of water vapours inside the oil of the pump, but how is it possible that lossless regulators are really lossless, if a certain enclosed volume, does not have lets say 99% vacuum and does have 90% if the pump is running at the same operating speed (revolutions) the only way I can think of to reduce vacuum is to introduce a controlled leak in the circuit, so how can the lossless regulators do it without leaks and therefore without introducing moist air in the pump ??? in other words how on earth does a lossless vacuum regulator work without introducing a controlled leak ??
Go to the Smc website then dig thru the diagrams how there made/specs. Mine is lossless except a bleed port on side of regulater. One thing I noticed is my 1mb pump will only go down to approx 50mb with the regulater. Works just like a air pressure reg. Both are pressures.
I have been doing my infusions with a vacmobile 20/2 system that has a vacuum regulator, that seems to work very well, but I don´t know if it is lossless or not, I suppose it is because IMO, the people at vacmobiles did their very best to make a top quality system, does anyone here know the brand of the regulator that comes with their pumps systems ??
Anyway it seems that the consensus here is the use of SMC regs
I’d really like to know which SMC (or other) regulators seem to work for people on here. I just got off the phone with an SMC tech and he said the IRV 10/20 series regulators leak at 10cc/minute or something. He could not say whether or not any of the other SMC regulators were lossless, maybe he just didn’t know.
Cheekybrad, which regulator are you using?
Sorry about delay, IRV20-LN11. SMC. My pump pulls 1mb but will only go to @50 mb through regulater.
