Expected air filter life?

[Iceni John]

Those little gauges used to cost $12,. Made in USA.  I haven't bought one in 15 years.  I wonder if John's gauge is Chinese.

--Geoff

The leaflet with it from the Engineered Products Company in Iowa makes no mention at all where it's made.   Usually anything made here proudly and loudly trumpets its "Made In USA" origin, but there was nothing like that with it.   What's more telling is that Donaldson bought the company a few years ago . . .

I'll play with it on the weekend and see if I can come up with a compensation adjustment after I measure it against a water-tube manometer.   Maybe making a pinhole in its rubber tube will bleed out just enough vacuum to compensate for its over-zealousness!

My turbo boost gauge still shows about 26 PSI on a hard pull, so that's another indication that my filter's still OK.

never had one on the m c i but have one on the featherlite and I checked it and it did show some restriction so I checked the new filter and found some leaf pieces in side against the filter ? vacuumed it off and all is good . so now I will look at the minder more often . so it can be useful   

my intake screen is less then 1/4 " mesh so only the busted up dry leafs were getting in . the intake is on the roof as if it was like a ram air system

On my 05 with an 855 there was always a little smoke and I was trying to find out why. ( another story but that is the nature of an 855 ) I added a minder and with a new filter that I thought was big enough the minder would go to yellow. I added another filter and now the minder has never went to yellow. I would think that is a good case that the minder was telling me there was not enough air.

I'm with JC. When you start blowing black under full throttle, time to change. You can take the filter element out and see if you can see lite through it too. Good Luck, TomC

I duct tape a shop vac to the intake side of my Eco filter and carefully blow compressed air on the inside of the filter to clean it out.
JC

Wouldn't you blow into the outlet so the air is pushing dust back to the inlet side?   (I wouldn't want to force the dust further into the filter media.)   Any dust that then settles on the floor of the canister could be easily sucked up by putting the vac nozzle down the inlet pipe.   Or am I all cattywumpus?

  a new filter, a light, and a light meter... or two eye balls.

John, by sucking on the intake side of the filter with the vacuum, and blowing through the other side (outlet), I reverse the flow and get dirt out.

OK, got it!   Or as Bart Simpson says, it sucks and blows at the same time.   D'oh!

Thanks, John

DO NOT BLOW OUT AN AIR FILTER!! By blowing out the air filter attempting to get more life out of it, you risk also blowing micro holes in the paper element letting dirt pass to the engine. Considering how expensive an air filter is (about $150) and how expensive an engine overhaul is (about $15,000), it just isn't worth being cheap. If you have a question about your filter, get a new one-and get a good brand name filter-Donaldson is one of the best. Good Luck, TomC

     That's the #1 rule that I've always been taught about air filters.  #2 is be *REAL* careful about taking a filter out and putting it back in again - often the seal on the filter will be torn or stretched and you may not get a good seal the second time you put it back in. 
     A "dusted" engine is a heartbreak in two ways -- 1)  $15,000, and 2) it's usually preventable with a little care.

An oil sample will confirm if you have an air filter/seal issue too.

Those $80 gas blowers are a good example. They don't have a fuel filter. I remember fueling one while the wind was blowing. Some grit must have got into the fuel. The next day when I was using the blower, it started losing power then died. Pulling the cord I had no compression. Dismantling the engine revealed heavy scoring on the inside of the cylinder.  There was an air filter but no fuel filter.

I bought the eco lite filter where the housing and filter are one piece and you throw the whole kit and kaboodle out when you're done. I like this approach because instead of cleaning it, I kind of have to replace it. Small price to pay for peace of mind

had is a better word..by the time an oil sample tells you anything it's to late...

An Eco filter is  not made out of paper.
