air compressor deal
Permalink  
 


Ok Guys. David here.

I know I am playing devil's advocate here but I want you all looking to purchase or upgrade to a newer or first roof cleaning compressor, to get the best value.

Here goes.

From my meticulous research (as some of you know I am a stikler for details) these are the reasons a compressor made like the one from Eaton I recommend is better than the Northern or the Water Cannon models we have been discussing.

Below is my breakdown of the specs on the Northern tool 5.5 hp model Mike suggested.

Mike S. You are great and a really cool guy and you know I like you and your company yet I also don't want anyone spending money on something that will not be as effective for them long term.

Some may, at times, be frustrated with my methods but I try to share the details so we ALL win here.

Thanks Again Mike for this suggestion, however these are the reasons you and others may want to steer clear of this one
  • Honda GX160 OHV engine with low oil shutdown (Good Solid engine with a 2 yr. limited warranty, however, 160 cc is too small for constant use at the level we need to use it, in my opinion)
  • 13.2 CFM @ 90 PSI; 12.7 CFM @ 130 PSI (This is ok, actually quite good for a small compessor used for our application with the NDP-15 or ARO A/D pump)
  • Single stage belt-drive pump ( pump has some shortcomings, ie. single cylinder, not dual, aluminum head, (will not last under constant load outdoors and is not rebuildable) single stage runs at a higher RPM which equals shortened pump life
  • 20-gallon capacity tank ( good, 30 gallon, better for more pause between compressor ramp up which = Longevity)
  • Pump has durable cast iron cylinder ( Good but most likely has an aluminum wrist pin and connecting rod and that is NO good as they are junk and wear out and are not rebuildable)
  • Aluminum pump head dissipates heat (Not Good, Not rebuildable, softer metal wears much faster)
  • Engine idles down after reaching 130 PSI max. pressure (Good)
  • Aftercooler cools air as it flows into tank (Good)
  • Pressure regulator maintains needed pressure (Good but depends on build quality of regulator-Aluminum, no good, Brass much better)
  • Provides dry, high-quality air at proper pressure to extend air tool life (good)
Hope this helps.

I have been researching all night long. Got to rest, early morning tomorrow.

David W.

Thanks Dave. I wasn't suggesting everyone should buy it. That's why I asked what you and Chris thought of it, followed by, it looks pretty good. I don't know as much about them as you and Chris.

I'm glad you posted all the details of why the Northern compressor is cheap!

I know exactly what you mean about getting what you pay for, I've bought stuff from Northern before that did not live up to my expectations.

I thought Chris might like it better than his Ridgid, it had some better features, but as you pointed out it probably wouldn't last much longer.

Great heads up buddy!

How much flow would you expect with the 8hp Eaton and the Yamada or ARO 1/2" pump?

The pump on the Eaton looks Chinese Dave ?
Emglo is a good air pump.
Ever look at Rol Air Compressors ?
The 5 year warranty looks good, but what about down time ?
I always keep a back up compressor for when one takes a ****.
I slap the back up on till the broke one is fixed.

At 1500.00. I need two, OUCH.

I LIK E the tank !!!

Here's a used DeWalt Emglo on eBay.

here's one similar to Chris's Ridgid in Tarpon Springs

I'm not suggesting anyone should buy these. I know used stuff is suspect.

I just wanted to post it to show people what's out there.

Tank Size is important, the bigger the better !
This eases the compressors life.
My friend had a Rigid hooked up to a seperate 100 galloin air tank !
The compressor just loafed, and spray was awesome.
I called the man in Tarpon Springs, the Subaru is a good motor, a real sleeper.
It looks like a chinese air pump though.'Hey, WTF, if the price is right, I will buy it.
NOTHING is "forever" when it comes to roof cleaning.
One can never have ENOUGH pumps.reels. air compressors disbelief

How can you tell if the pump is Chinese?

I have OWNED several Chinese Pumps that LOOK like those.
NEVER had a problem with the pumps Mike, just the junk Chinese Honda Motorcopys.
The compressor on Craigslist might be OK with the Subaru Motor ?
I just use em till they die, and junk em.
After a year on MY roof cleaning trucks, they are all rusted out anyway.
Remove and Replace blankstare
A Day in my life.

I looked really closely at the pump and was told by the Mfr. it is American made. It gave away no details of being chinese.

The indicators I looked for were ,"No Visable Chopsticks, no take out menu or fortune cookie" I checked the pump over by magnification in m,y picture editing software and never saw even the slightest bit of left over DUCK SAUCE, LOL

Seriously, I will give the company a ring and double check for clarification.

Emglo Brand, builds a good compressor and so is Rol Air, no doubt. I used both Emglo and Rol Air for several years many years ago with I was framing houses for a living. They were long lasting and for nail guns they worked teriffic, supplying all the air 2-3 guys needed to keep framing most of the time, I think the Rol air was a 15-20 gallon and the Emglo was the standard torpedo 9.5 gallon size with the single pump and 5.5 hp honda.

Don't get me wrong, I even like the Northern Tool compressor Mike S. brought to our attention. I am just looking at all options and the pro's and con's of each model.

I hope everyone takes my reviews and findings with a grain of SH, err, I mean salt.

I just know many of us are upgrading or looking to upgrade from other chemical delivery methods to air diaphragms and the key beyond having a Kynar pump for longevity is the compressor reliability. Am I right Chris?

So, with a large volume SINGLE tank (30 gallon as compared to a 9.5 gallon capacity Dual torpedos) and a DUAL head pump and electric start Honda motor, this seems like a WINNER in the Eaton Compressor.

The icing on the cake is the 5 year Bumper to Bumper, non pro-rated warranty which means PARTS and LABOR are covered for a FULL 5 YEARS from what I understand and unlike a pro-rata warranty which decreases the munufacturers liability as the equipment ages, the 5 yr, bumper to bumper means if anything breaks the will replace at no cost to the owner. At least that is what I have been told and have verified by tracking down a couple of the companies listed in the Eaton testimonials and the told me that Eaton Compressor bent over backwards to make it right everytime with no questions.

Yes, the cost is more than the OTHER cheaper models out there, and the features are less on the less costly models and no electric start (which is a nice feature)

I am just thinking that if it lasts 4-5 years and you buy a 800.00 compressor every year that is half what this compressor is in terms of quality, air volume (21 cfm compared 11.2 or 12.7) and has a warranty that is unrivaled (5 years Full as compared to 2 years pro-rated)

Then the bottom line is cost.

Breaking it down- Your current compresor at $800.00 X 5= $4,000.00 as compared to $1,450.00 for the Eaton = Savings over 5 years of $3,550.00 plus time saved over removal and replacement of 5 different compressers as compared to bolting one compressor down and it "stays where it lays".

If you bought two the savings over 5 years would be $7,000.00 and thats the bottom line on your bottom line.

These numbers and reasons are what I look at.

Hope this helps biggrin

David W.

Great finds on some good used compressors Mike. Good job, Buddy! Thanks for the heads up! Some of the prices aren't bad and the subaru engine dual torpedo is actually probably a great compressor if the price is right.

What size nozzles would you use?

It would be awesome for sure !
With the 17 CFM Rol Air Compressor, flow is almost too much to deal with on most roofs !!!
My experience with air compressors is I get about a year out of them before they rust out, or take a chit.
A seperate air tank is best, but we have no room.
The Eaton would solve THAT problem, but reluctant to invest 1500.00 in something that is gonna rust out in a year anyway ?
The compressor on Craigslist I can buy for 500 dollars each!
IF I get a year out of it, cost of doing business ?
I SURE like that 30 gallon tank on the Eaton !!

I found a good deal on a small air compressor to go on a 3/8" 7gpm air pump.
