We are testing our newer compressor the KAC1 Keene
Testing started 2/13/09
We have made 3 major changes.
1. We installed a new seamless polished stainless steal cylinder sleeve
into the compressor head. Our first Bach of compressors has a hard anodized
cylinder with Teflon seal. This worked great for a 100 plus hours however a
lot of debris came out of the compressor in went into the new filter. Also
the hard anodized material was coming off of the walls and the cylinder was
wearing out as well as the cup seal.
2. We also switched to a high quality stainless steal reed valve.
3. We added a simple 30 mesh screen and a felt filter to the top of the
compressor. 90% of the problems we had last year where contamination in the
reeds valves. All it took was a seed from a tree, twig any kind of object
would get logged in the compressor reeds and lock it open or closed. The
simple screen and filter totally solved the problem.
Test results 2/12/09 3.5 CFM at 30 psi max 65 psi.
Test results 2/27/09 336 hours of running 3.5 CFM at 30 psi max 65 psi.
Running at 30 to 55 psi changing every day or so.
Head is running cool 110 degrees the compressor has been running 24/7 it has
rained for several days no problems.
Test results 3/07/09 576 hours no change in performance running constantly.
We are now raising the working pressure to a constant 55 psi.
Test results 3/11/09 650 hours we did a tear down on compressor and did a
quick video. Every thing looked perfect No signs of wear.
Since everything was going so well we decided to do some tweaking on the
compressor. We reduced the volume in the compression cylinder, and what a
difference. We added one small spacer under the cup seal to see what would
happen. We where getting 3.5 CFM at 30 psi. and maximum of 65 psi.
We are now getting 4 CFM at 40 psi 3 CFM at 50 psi. and we pegged our 160
psi pressure gauge.
The higher working pressure did raise the head temps from 110 to 130
degrees. As soon as we dropped the pressure down to 40 psi the head temp
went down to 110.
This has been a fun project. I love it when things go well. We are
currently at 700 hours running strong with no problems in sight. This
weekend I am going to kick the psi up to 120 and let it go to town see if we
can blow it up. Good old fashion destructive testing.
Just to see what the compressor could take we used a double spacer under the
cup seal and Wow!!! This compressor is unreal bad to the bone. However the
compressor is running much hotter and this higher head temps and crank temps
may shorten the life of the lower end by cooking the grease out of the
bearings.
I call this the dragster performance level. Full out, however only a few
runs.
With the single seal spacer this is called the performance tune this
compressor should last for many years of hard use.
With no spacer Stock mode. This compressor should last forever.
update
Well we made it through the weekend at 120 psi with no problems, however we
are pushing our luck. Our original design was meant for a compressor to
provide enough air for 2 divers down to 20 feet. At this point we have
exceeded our expectations. We are no going back to the single spacer. The
high temps may have taken there toll on the lower end of the compressor.
Update we are currently at 800 hours and running strong. Back to 30 to 55
psi. I am getting tired of seeing this dam compressor run 24/7. I tossed
some dirt and grime into the fan area of the compressor it is still kicking
ass.
With the single spacer we running a constant 4 CFM at 30 psi and 2 cfm at 60
psi. The compressor will go up to 150 psi with no problem. Keep in mind we
are going to add a 55 psi pressure relief valve. I want to be able to run
the compressor on our smaller LP air system with the plastic tanks. The
stainless steal tank are getting to expensive.
Update 835 hours
After letting the compressor run at about 55 psi for the last several days
we finally killed it. I believe that when we had the double seal running we
cooked the grease out of the main eccentric crank bearing. The bearing was
dry no signs of oil and it started squealing badly. The other two lower
bearing look great. I am confident under normal working pressure of 20 to 50
psi this compressor should last for at last for thousands of hours. The new
stainless steal sleeve really made a huge improvement on the compressor. The
cylinder head looked perfect no signs of wear. The cup seal had some wear on
it however it could have gone hundreds of hours more.
So we are going to production at this point. This is hands down the lightest
strongest compressor ever belt for our industry. This compressor tipples
the output of the t80 and comes close to the 263 compressor.
