t-80 compressor air filters ( 23:13:50 ThuDec 13 2012 )

I just received my new T-80 compressor and I am curious about downstream air filters. I'd like to add an air filter and a moisture trap ahead of my air tank. Does anyone have a recommendation?

Hey Jim - What are you trying to filter out? The T80 has the little filter on the intake to keep parts out of the compressor. It also filters out most of the stuff that would go downstream to you. If you put a snorkel on it you can use a sock over the intake rather than the felt filter. This allows you change it/clean really easy and as often as you like / need. I have mine this way.

I wouldn’t put a moisture trap on it. The air is dry enough already and breathing through your mouth all the time will give you enough cotton mouth as it is. The other thing is I would be worried that the trap would be a good place for something to grow that you would want to breathe in.

Lastly, I would be concerned that the T80 wouldn’t have enough Umpf to give you air and overcome the resistance of a filter. At about 7’ I can easily out breathe a T80 in normal dredging.

Keene does make an in line filter for their KAC1 air pump. Again I’m not sure if the T80 will be strong enough for it. If the inside filters gets wet you have to pull it out and let it dry as it blocks so much air flow nothing will get by. I have one for my KAC and don’t use it.

I know you will get more opinions than this so go with what works best for you

Hope this helps

Steve has some good points, I wouldn't use a moisture trap. There is really no need for it. Any moisture in the form of vapor is welcome to keep your mouth from drying out. The only reason they are used on other compressors is to keep moisture out of your tools and equipment.

Thank you very much for your replies. I am very happy to hear the filters are not needed. I saw a moisture trap and a filter on a dredge last summer and assumed it was a necessity as it is on high pressure compressor units. You have saved me worry and money. I appreciate that very much!

The hookah systems are all new to me so I appreciate all the information. I'm going to try to gear up for this type of prospecting this summer.

Looking at Keene Eng. site, Introduction To Hookah Diving says: "We highly recommend that all hookah systems be equipped with a particle filter. The particle filter should allow nothing larger that 40 micron to pass. This filter is best located at the discharge of the air reserve tank".

Here's a link to their online pamphlet; http://www.keeneeng.com/pamphlets/introHooka.html

Thanks again guys,
Mike

Keene makes a valid point and I proved it the hard way.

My t80 diaphram was slowly deteriorating and crumbling tiny bits of material all the way thru the hookah. At season end I rebuilt the compressor, air lines, fittings and regulator after discovering the bad news. You don't want to breath machine parts.

I found an inline filter used by scuba divers. It's all metal and 1/4" pipe threads both ends. It came from Florida and was under $30. I experienced no loss of air volume.

The t80 is a low cost unit which easily produces good volume at low pressure. If you need greater depth capacity you'll need to raise the psi of pressure beyond the t80 range.

The moisture condensation is your friend. Divers can become dehydrated.

Hi Rod! Can you give us the computer link or address of the place in Florida you got the filters? Thanks in advance, JAB

Hey Jim

Sure I will. Glad to.

It's stored out in the shed in a rubbermade tub along with the rest of the system. It's snowing today but I'll get to it. Are you in a real big hurry?

I'm gonna do a google search and try that first. I think the receipt and packing sheets have disappeared.

BTW......

I remembered another defect in the t80 when I rebuilt it. The crankshaft to connecting rod assembly where factory assembled incorrectly. The crankcase and rod end rubbed each other due to being off-center. The aluminum shavings and dust were also sent to my breath. Not good.

I just looked up a good filter from Grainger, but it is not the same one in the link posted above. This is a much smaller filter; http://www.grainger.com/Grainger/SPEEDAIRE-Nipple-Filter-1EJV3

I will order one of these SPEEDAIRE filters right away.

Thank you!!!

There's 2 on this page-

The speedaire @ $8.32 might be the same as mine.

Good one OJ.

You're on the right track. Carry a spare in your parts box.

No Rod, I am not in any hurry. Remember, as you, I am an old retired guy, don't get in a hurry for anything much these days. Think I will check out Grainger website! Thanks for all the great info. I've never used an air line filter in over 35+ years of dredging, however even an old dog can learn new tricks. Merry Christmas and have a great New Year. JAB

Hey Rod! Found the website for what I believe is the same filter Keene has in their catalog and almost half the price. http://www.grainger.com/Grainger/SPEEDAIRE-General-Purpose-Miniature-Air-Line-4ZL08?cm_sp=IO-_-IDP-_-BTM_BTB05209020&cm_vc=IDPBBZ2 Perhaps others may be interested in this item.

I have never found the need for any other filter than the standard felt filter at the pump but I suppose it wouldn't hurt to have an additional filter in-line from the air reserve tank/regulater but I'd be leary of using a filter designed for a standard 100/130 pound compressor ($32.00!!!!!ouch). You might just be better off with a cheap $4.00 plastic in-line fuel filter from your local Napa store. Check around and find one that has the correct size for the ID of your hose. But before you do try experimenting with and without it to see if you notice much change in air volume. You can never have to much air but to little is a pain in the arse.

This guy built a cool hookah system although his floats look a little inadequate.

The remote possibility of the t80 adding particulates to your breathing intake is a real consideration which everyone should prevent. It happened to me and I won't let it happen again.

Any mechanical underwater breathing apparatus potentualy is gonna fail. Mine slowly failed because of bad craftsmanship from the human assembler. I think it's reasonable to assume mine wasn't the only example of an unhealthy hookah system.

The hookah system requires regular sterile maintenance. Dave has written instructions which describes the reasoning and actions necessary. If I had disassembled my brand new t80 before using it, I could have avoided the trouble.

I purchased a couple of 40 micron inline filters from a local tool suppy for $8 each this morning. These are the same filters used with most air tools. Some even have replaceable elements. Safety is an issue that should never be neglected, and $8 is a small price to pay to protect your lungs and health.

Just a word of caution, especially to the newer guys to dredging,if you are using a small filter like http://www.grainger.com/Grainger/SPEEDAIRE-Nipple-Filter-1EJV3 and that is fine as 40 micron, I would be sure to practice some bail out drill with your weight belts. It wouldn't take much to clog a filter with little of a surface area and 40 microns. Even water could be enough to cause you problems. Mists is considered to be about 70 microns and Viruses are about 2 microns, it really won't take much to clog a 1/4" round 40 micro filter.

I would also be sure to disinfect it often with something like a strong bleach solution often. Nothing like a moist and dark area to grow something. Even your ear beer, or what ever you use, would work

Not to be argumental or anything, you guys that want to use these very fine filters do yourself a favor and take a short section of your air hose and breath thru it, attach that air filter to the hose and now put that puppy up to your lips and breath in. Any restriction? Plenty of air? My point is that hour after hour of insuffient air is much more of a health concern than breathing in all the airborn particles that we breath in naturally during the course of a normal day cutting wood, stoking a fire box, cooking food, driving that dusty road to the mining site, working on your engines, etc.. We don't have gills so please take getting ENOUGH AIR underwater your primary concern. And yes, keeping your system clean with basic cleaning is also as important.

Back when I did dredge in Ca. each year I would put listrene mouthwash in my air system before the season started, I did away with the T80's after waering out 3 of them and there was always alot of black crud come out of the t80, ...A GAST compressor is the only way to go.:beatingadeadhorse:

Hi there,
regarding filters,
I would put a mousture trap after the air reciever if you are using one,the problem of water asperation is very real if there is an accumulation of moisture in the tank because of condesation,I have suffered from salt Water Asperation and it feels like your lungs are bruised and like having the flu,it only lasts a few hours and in my case the problem was water coming in through the exhaust valve on the Regulater.
Kind regards.
Tom. from Australia.
See you all in May.
