Bio-Circle 100 Micron Replacement Filter Cartridge

Keep Your Parts Washer Running Clean

Every welder and fabricator knows that a clean weld starts with clean metal. The Walter 48M542 Replacement Filter Cartridge is the key to keeping your Bio-Circle parts washer performing like new, ensuring that every bracket, flange, and pipe you wash comes out free of grit and oil. When you are prepping parts for welding or inspection, the last thing you want is a parts washer that spits dirty fluid back onto your workpiece. This 100-micron filter acts as the kidney of your cleaning system, trapping the metal filings, shop dust, and heavy grease chunks that wash off your tools and materials.

Designed to fit the Bio-Circle L, Maxi, and Compact models, this filter is the unsung hero of the workshop. It works by catching debris down to 100 microns—roughly the thickness of a human hair—preventing that sludge from settling in the bottom of the tank or clogging up the flow brush. When the fluid stays clean, the natural microorganisms in the Bio-Circle liquid can focus on eating the oil, rather than fighting through a soup of metal shavings. This means your cleaning solution lasts longer, smells better, and works faster, saving you time and money on fluid replacements.

Swapping out the filter is a quick, mess-free job that gets you back to work in minutes. If you notice your flow rate dropping or the fluid looking particularly murky, it is likely time for a fresh 48M542. Don't let a clogged filter slow down your prep work. By keeping a fresh cartridge in your machine, you protect the pump from burning out and ensure that when you pull the trigger on the flow brush, you get a steady stream of powerful cleaning solution ready to tackle the toughest grime in the shop.
