Where to purchase a secondary filter tower and priority valve?

[pescador775]

For the acronym impaired, PMV = pressure maintaining valve = back pressure valve. Sounds like a good deal. Craig, when are you going to get a website?

Craig, when are you going to get a website?

Well, if you are interested in that product or filters go to Filter Techs - Lawrence Factor air filter dealer - breathing air specialists, discount prices

If you want to see some neat stuff that we build/represent go to Nautilus - YACHTDIVE.com

If you are interested in some non-diving related topic go to Gems of the Rainforest: Emerald Tree Boa - Corallus caninus care breeding

But only go to the last one if you like arboreal snakes of the genus corallus, lol.

Jim, August Industries is one of the better dealers in the business. Also $435 for the 16" filter is a good price.
Hyperfilters are more than just adding a pressure maintaining valve and check valve. The filter itself is not the same as the regular LF filters and are not interchangeable. Hyperfilter may not be required for your needs or wallet but certainly is added protection. Depends on what your needs are. From my point of veiw I always try to be on the safe side even though it may be overkill sometimes.
I think more filtration on almost all compressors is a good idea. But that is expensive and heavy. Bruce

If you are not opposed to LF products. I will offer you a 3 lb tower, pmv, bleeder and inlet check valve for $680.00 or the same except with a 1 lb tower for $600.00. You provide the mounting hardware or add $25.00 too either price for unistrut clamps and channel. Towers come with initial cartridge. Freight is extra. These prices are slightly above LF's list for the tower alone.

BTW, you can substitute a "65" series cartridge for a "53" series to save money. I can also point you to a site that sells LF filters at discount prices. Just drop me a PM.

Anyone who thinks a hyperfilter will guarantee good air from a failing compressor is living in a fool's paradise. Any decent filter, stock grade E included, can product good air from a failing compressor! The problem is, it can't do it for very long. And the hyperfilter can do it for longer, but only a little. So ultimately, the key to clean air is not necessarily mulitiple stages of filtration, but careful monitoring of the air system. All the hyperfilter does is buy the operator a little more time, which can be useful with a busy or poorly supervised air system.

Re OCA being "sometimes" produced without a hyperfilter, it would be more accurate to say "usually". That is too say, it happens more often than not - labs that test breathing air will tell you that most of the air they test, from plain old single stage grade E filtration systems (no hyperfilter) meets OCA standards more often than not.

Finally, many very knowledgeable people in the dive industry have come to believe that Grade E air is fine for PP mixing, as long as it is really grade E, and the main reason for a hyperfilter is not to superclean the air, but just as a backup to the primary system.

My particular unit has a check valve where the cascade connects to the appliance. The purpose of the appliance is also to quarantee results. The appliance produces hyper pure even from a failing compressor. When partial pressure blending this is really a must. You are correct however that OCA is sometimes produced without an applaince or even a hyper filter, but it's just not worth the chance.

"Hyper filter" hype makes some divers nervous every time they drag an OC tank into a different dive shop. In their mind, "bad" air is lurking behind the next wall. Yet, I know of many PP fills that were done using a small, portable compressor with stock filtration system. Never heard of a problem. Back in the day, this practice made me a little nervous, too. We learn as we go. Perhaps, a more frequent inspection/cleaning of a tank would be in order, but no need to over do it.

The august industries short tower is a Bauer Knock-off. several companies buy them such as Stark Industries. They use a Bauer or LF cartridge. Stark industries, I believe, several years ago, tested two of these to destruction before switching all their compressor filter systems to this supplier. They exceeded 16,000psi before destruction.
Good filters, I use them on some of my compressors and they still provide grade E quality air at the end of the change cycle.

Please tell me more about this:

This system which I designed is an inexpensive filter which gives very good air filtration. It is a new York 50 cu in hydraulic accumulator rated at 3000 PSI. I bought a large quantity of these, after I had testing done to confirm the 4 to 1 safety factor because I wanted to use these in my systems at up to 4000PSI. I sent two chambers to Stark Industries in Houston to be tested to destruction. Both chambers exceeded 16,000 PSI before explosive destruction. With that safety factor in mind I machined the new fitting from stock 10,000 psi hydraulic fitting using no welding or process that reduced the fitting s original structural integrity. The inlet fitting provides air into the system through the extended tube (Copper), while allowing moisture to be vented through the side exit of the "T". A valve is attached to control the venting( not shown).
The top fitting has two possible configurations: one to accept the large cartridge with white caps which can be repacked with chemicals (usually Linde 13x) for paint ball applications to provide dry air. Two of these could be used in pure air applications by filling the second system cartridge with activated carbon and hopcalyte.
The other option provides a fitting which accepts a 42XCAC ( shown empty) or Lawrence factor filter for breathing air applications.

Thanks for your detail info.

I like your idea of a drain valve that must be very useful.

For a re-packable choice, a cartridge/canister is a "must have" item????

As I know, the media can be repacked directly into the accumulator without any cartridge/canister.

Your accumulator seems to have the same inside/internal parts with the pictures below.

Please let me know if I miss something here.
