Distribution blower filter? Why not?

[SmokeyTheBear]

Just for giggles I'll toss out a couple of figures my stove had a 160CFM blower on it and couldn't burn a decent pellet on 3/5 for any real amount of time without high temping out unless you did the old fan over ride trick and tell the fan to run full speed. Even then it wouldn't allow the use of heat range 4 and above, I did a bit of poking around and located a cheap 230CFM blower which does a fine job (turns out a close cousin of my cheap blower is used on another manufacturer's version of the same stove only difference is it has a even slightly higher flow rate).

There was another issue with the stove and that was the controller was incorrectly set up (those jumpers will get you every time it seems).

So I suspect I now have a bit of CFM I can afford to loose.

Before anyone says gee that must have put a higher load on your controller it didn't, both of the current blower motors on the stove are well below the controllers ratings and about half of what the originals were.

Next up is a reduction on the auger side but it can wait.

I would just love to do a bit of work and get an air filter on the beast. I'm tired of always removing fine dust from the blower wheel.

But blocking the coolant flow is a big no no and that is what happens on the output side if you place a "normal" filter there.

I am agreeing with you. Air at the output of a blower is turbulent and you can't push turbulent air through a filter. It is always preferable to have blowers pull air through anything that needs air flow.
We are talking about keeping dust bunnies out of a blower. A coarse screen should be able to do that.
Another thought..... Dust bunnies are notoriously poor climbers. If the stove is a few inches off the floor they will die of exhaustion trying to get at your blower.

A screen sprayed with a substance that stays tacky....would catch the dust bunnies.

But pellet fines are not so heavy butted as dust bunnies and actually some of them float around a bit, they also can get into the shells of some stoves from the hopper area during bag content dumping.

What is even worse is they can follow the air flow, and into the heat exchanger and eventually come out as other than pellet dust.

Oh well, stuff happens, I guess.

Did a complete clean on the Cab Saturday. Fines were all over the shell floor. You also have to deal with (if you have) dog hair, cat hair, debris from carpets. My desktop tower is about 4" off the floor (hardwood) and it gets loaded with dust & other unknown matter. Screens will have to be checked and cleaned often but will work.

So has anybody made any type of filter for their stove? For any Harmans??

I made a filter and it seems to work great....still get a nice flow of air out the front.

How did you make it and any pics??

Did you try one of these convection blower screens? They do work, I have seen them on other stoves! I just ordered some!
