Magnetic Fan filters on amplifiers….

Ive got a B&K 200.5 with a AC Infinity S8 on top of it.

The AC infinity draws air up and spits it out the back and keeps the B&K nice and cool but the act of drawing air up results in quite a bit of dust getting caught underneath the B&K…. And it’s a bit of a pain to move a 76lb amp to dust it.

I was thinking about putting some sort of filter material underneath the B&K (since the bottom is the only open area) which would be easier to remove and clean, and keep the inside of the amp cleaner.

But I was thinking going with magnetic type filters would be bad but wasn’t sure.

Anyway, any suggestions welcomed.

Also I was planning on adding magnetic filters to the bottom of the AC infinity but if that is a bad idea given proximity to the B&K let me know too…

    I wouldn't restrict air movement. Are you going to monitor the filters more than you're dusting now? 😃

    Lol yes I would be monitoring them more, and it won’t restrict airflow that much I don’t think.

    After cleaning the bottom of the B&K the AC Infinity hasn’t even kicked on yet (which it does as the temp in the amp goes up) lol….

    Is the amp in a confined space? As long as the heat sinks are open and accessible that should be adequate. Not sure I'd put anything magnetic near an amp.

    It’s in a cabinet with closed sides but some vent holes in the bottom, open front and back.

    I built an enclosure on the back of my rack and used these to suck hot air out of the enclosure. That way cool air is coming in from the front.

    Ended up just getting some non magnetic 80mm ones at least for my pro amp which only had basic hand protectors.

    What I got

    What was there

    I will eventually just get one of these to go directly under (but spaced out from) the bottom of the B&K.
