Alternative to Dolmar HD filter?

[t4driller]

I'd like one that flows as good as no filter and stops 90% of the dust.

Put me on the list for a few as well.

I seen this post is almost 5 years old. Anyone come across a different filter for the HD kit that has better flow?

I have one done, just need to cnc them. It uses a k&n with the black filter sock. It's designed for the HD filter housing.

You should post up some pictures when you get one assembled. The HD cover still fits over the K&N filter?

You gotta trim the top cover just a wee bit.

What do You want?
Longer service life, better filtration, or higher airflow?

FFS, just go with a fine white nylon AF and be done with it!

Can't run a velocity stack on any of those filters.

Do You have a CNC program You would share?
CAM/CAD or G-code?
I have access to CNC mills, might play with this.

No, I don't have a single HD AF setup for my saws!

Chainsaw operators and their kinks!

OK, what does a velocity stack do?

Hahahah no. But you can buy one when I make them.

Is that like wearing nylons and high heels when you run a saw?

Speeds up airflow

I personally will never need one, but thank You and GLWS!

And yes, that's about what human kinks are about.

Speeds up airflow

Speed up airflow to counteract the HD AF inlet elbow restriction?
Flat top AF is good enough for me.

I really love the AF setup on the PS-550 & PS-6100.
I would love to graft those filters onto the 64xx/73xx/79xx units.

What’s the part number for that K&N filter? I tried using the number B020A4 from the top of it from the pictures but didn’t have any luck.

OK, I looked it up.
Wasn't there supposed to be an OEM velocity stack featuring HD AF setup introduced?
Something like an upgrade to the original HD AF?

957-173-400

I made my own Uni foam filter, I honestly think more people will lean toward using that vs k&n.

I need to run both back to back.

I just don't dedicate a lot of time to saw stuff...
