I've read warnings that sawdust should not be blown from an air filter for fear of tearing it. Do you millers attempt to clean an air filter in any way or just replace it? I direct a gentle air stream over the filter but I am always uneasy doing so.

I blow it out with the leaf blower. Before I had electricity at the mill I took the filter to the shop and blew it out with compressed air...easy does it and I've never had a problem. Blow out the filters on the tractor and truck also, but still change at regular intervals.

I just bought a new one today, I knocked the dust out of it a few months ago and lightly puffed some compressed air around it. 5 oil filters and oil, too.

I run a Kohler Command 25 on my mill. It has a regular duty round, pleated paper air filter (not the cyclone) and I clean it by blowing it with compressed air from the inside out - won't hurt them at all. I've been doing it for 30 years on both my own stuff and customer stuff also.

cheers

OK! the score is 3 to 0 in favor of cleaning - I will continue what I have been doing w/o fear of compromising the engine.
Thanks,
Bob

4 and 0, compressed air is almost free

. Just serviced my tractor tonight and removed the air filter and blew it out along with the radiator fins. Good question would be if K&N makes reuseable air filters for small V-Twins

I use compressed air on all my engines. Just hold the nozzle a distance away, and don't hold it in one spot for too long.

i'm sure if you had a part# you could cross reference a match to fit on there site

I knock it around to loosen the dust and then turn the leaf blower on the inside and blow the dust out. Yes, I've used compressed air, but I really like the leaf blower. It also does a good job of cleaning the mill.

I would not use a K&N filter. The oil would attract the sawdust, and I suspect that it would clog quickly.

Good point but they use them in dirt track racing an that is real fine silt, but maybe they need the oil to keep all that out?

If it's dry, I can knock/blow it out. Even the vibration of sawing shakes some loose. Sawdust dribbles out of the "weep" hole in the bottom. With an "oiled" filter, it ain't coming loose, and especially those diesel filters aren't cheap.

ScottAR · « **Reply #11 on:** December 01, 2009, 02:03:34 am »

I wouldn't use a K&N on anything I cared about...
They flow more air because they filter less dirt. end of story.

I blow off air filters with compressed air with low pressure.

K &N makes some of the best filters there are imo and they clean quite easily you can use them dry only the outerwear (foam ) use oil I've run one on my racecar for 20 yrs It's like anything else a lot of times people don't make sure they fit correctly and aren't sealed that's where the prob comes in sawdust is much coarser than the dry dust off a dirt track but like I said JMO

In any of the mechanical trades there are procedures and shortcuts that work fine if done with safety and skill,those are the very ones the directions warn you about because some clutz has screwed up.If I have a task to perform I always glance at the warnings they are usally the quickest most efficient way to do it if done with good judgement, sad but true.Frank C.

Gday

Im one for blowing it out but after the first go i pour abit of petrol on it from the inside out then blow it out again then let it dry and wack it back on the mill same goes for the foam filter on the outside i find it gets most of the finer particals out just like when you do your chainsaw filter it mightnt be everyones cup of tea but it works for me and has for years

I always use compressed air to clean out air filters. I have a small regulator attached to one of my blowguns to regulate the pressure down to 40PSI. This helps to ensure that you dont blow holes in the filter. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=90590

When I am out cutting firewood or cleaning out fence rows, in the chainsaw box I now carry one of the CO2 regulators with a 20oz canister attached. http://www.lowes.com/lowes/lkn?action=productDetail&productId=82384-61735-J-6901-101&detail=desc&lpage=none This allows me to clean the air filters on the saw when I refuel and to clean around the filler caps to keep the sawdust out of the oil and fuel tanks.

As with anything, air filters have a limited life, I use the compressed air to extend its life by keeping it clean so that it can do its job. A dirty air filter is restricting air flow, which will change your air fuel mixture slightly. When I notice the paper of the filter starting to rough up with the air nozzle then it is time to replace it, after all I do want the air filter to do its job.
As for the K&N filters, I have not been impressed with them. I ran a double filter set up with the paper filter as the secondary filter and it was catching all the dust, the K&N was still nice and clean.

Usually when we break for lunch, I'll remove the breather cover and blow that whole area out with the leaf blower!
After that's cleaned out, I'll remove the air filter and the foam pre-filter and blow them out too!
Depending on the way the fine sawdust flows (prevailing winds), I may do it again at the end of the day!
After about four to five cleanings, I'll wash the pre-filter with the "soap & water" blade lube, wring it out and replace the paper filter!

my sawmill is equiped with a honda 20 hp and it has a flat filter. i've never had to do more than tap it on th mill upside down a few times and replace it every 50 hours or so. i use compressed air in my truck ,chainsaw, and tractor filters with no problems.my mill may not get as much dust as some because i run a 36'' fan at my back that keeps the dust going away from me when i'm sawing.may be hard for a portable miller to use but it really helps on my stationary setup pc
