Better Air Filter for Stihl 025?

[ButcherGY54]

Hello All.

Anybody know if there is a better air filter for the 025?

If not, I am thinking of wrapping the stock filter with foam from another filter to make a pre-filter. If this is too restrictive I may remove the stock filter material and just use the foam. Do you all think this might work? The filter on this saw gets dirty real quick. I have a sharp chain and the filter is still always full of crud in no time.

Thanks.

I've seen saws with panty hose wrapped around the filter as a prefilter. It'll keep the bigger stuff, and even alot of the smaller stuff from getting into the actual filter and makes it easier to shake it off when you need to clean it. You'll still have airflow problems if you don't clean it enough, but it'll make the actual filter cleaning easier.

Jeff, is that sheer, control top, etc?

I remember someone saying that they crank down the thumbscrew really good and snug so the cover sits up against the filter really well, and they didn't have near as many problems with the filter getting crappy fast. I have heard several people say the filter on their 036/360/361 saw gets dirty fast but I have not had a problem at all with the cover on nice and tight. I'm assuming the filter on your saw has to be very similar.

I was going to try something like cheese cloth or nylon screening but I really like the panty hose idea. Its worth a try especially to keep out the medium & larger particles. I am willing to bet it keeps some of the finer stuff out also and makes your normal filter last all day with out cleaning.

I suspect air restriction is probably very low with this type of add-on.

You could always buy a Husky and not have that problem I guess .(head down,here they come!)

keith.. do i have to hit you with my 181? or the 288? or the 2100? *G*

 

[keith c raymond]

Ive got friends (true)! that swear on the air injection and I am a believer, too.Hey do you want that 8000 for parts?

 

[NWCS]

right now i just cant afford to shell out that much at this time.. im sure you have some other lookers on that, since nobody ever sells parts for em.

Stay away from fishnets. Kinda defeats the purpose.

Not a problem - my air filters on my husky's stay clean pretty darn well if you ask me. I liek the air injection or whatever they call it just fine thank you very much!

I believe we get overly concerned with this air filter issue, every time we see some build up on it we want to clean it to new condition, this build up only proves the filter is doing its job well. We really do not need to tap it out or run it under compressed air every time we add fuel and bar oil.

Jeff.

Thanks for the idea! I'll give it a try.

As for being overly concerned with the filter, it gets so dirty in one tank of fuel that it will not restart until I brush it off. I am thinking this is because the only plac it has to get air from is the bottom of the housing. I may get another filter cover and modify it for better airflow.

Thanks.

Me thinks that some of you manly men know way too much about pantyhose, eh? Unless you're a Canadian lumberjack and you're familiar with Monty Python.

Just kidding; I grew up with two older sisters, and I've been married over 18 years. I definately know way too much about pantyhose. Until now, however, I've never had pantyhose & chainsaw air filters in the same thought. Maybe I can talk my wife into wearing some seamed fishnets and helping work on my new old Jreds. Hmmm........

I have just blown my filter out with air from the inside out, every few hours of use. The last time I took the filter off there was a little dust under the filter, on the carb area and filter seat, some dust had gotten through. I know this kills saws, can you hurt the filter (put holes in it) from high pressure shop air? I didn't see anything but I can't think of any other reason I was getting dust past it.

This is definitely one place I hear the Huskies are way better...

oh yes, the air compressor can very easily kill filters. not just saw filters.. but automotive filters, or any filters for that matter. every time it gets blasted, the holes get blasted out too.. bigger and bigger. i just brush off my filters with a paintbrush i keep around, and then detail clean with a tooth brush. if they are nasty enough to use the air compressor, that baby is due for replacement.

heres the piston and cyl from a TS400 chop saw i got free out of a trash pile that was run with bad filters.

bearings let go and destroyed everything.

air filter

The correct way is to wash the filter in detergent and water, then air dry it.
Now, no sink in the woods and who wants to wash the filter every day!
I use air, either low pressure, or, hold the nozzle back. If the filter is oily, I think a brake cleaner works well. Let it dry or the exhaust fumes will killl you, not to say what the cleaner is doing to lubrication.
The brush, be very careful. You are pushing some of it through, plus it is hard on the filter material. I have seen filters ruined this way.
I would rather see someone tap the filter to remove sawdust if nothing else is available.
The very fine dust inside? A little is not that much of a concern. It is being trapped by the oil residue. I said a LITTLE. Anything more, the filter may need replacement.
As for the cutoff saw cylinder, that is a severe situation. The filter plugs and draws the dust through the crank seals, or, the operator throws the filter away. Happens all the time. Sawdust is a little less abrasive than cement dust.
Finally, they do not last forever. You must replace an air filter if it shows any sign of light coming through unobstructed.


Oh yes, no WIRE brushes. Had an 028 seized, pulled out a bristle. He was serious, " it was really dirty, needed a stiffer brush".

I have sprayed with brake cleaner and blown out from the inside with air, but close up, maybe I will buy a new filter, cheap insurance.

What happens when brake cleaner burns? I never did it with the saw but I remember trying to clean a throttle body on the truck with it with the truck running and it did not smell good. That stuff is really toxic when it burns, huh?

Yeah, there is enough that you see specks against the nice clean black background, but not a lot. I would rather see none though.
