The concept is to build extremely efficient units that sell for as little as possible. 

We have done our best to design sturdy and reliable filter units that work well and cost less.  For more information on how our filter units work and why Filtering Machine Coolant is Important refer back to our Filtration Index. 

Nothing Tells the Story Like Real Numbers 

Below you can see that our units are incredibly effective in spite of their low cost.

Notes: 

1.  The laser approximates counts and then uses algorithms to estimate total number of particles which accounts for the unusual results such as the repetition of 44,906.

2.  With the cloth filters you get a replacement of hard carbide and diamond particles with cloth particles since the hard grit abrades the softer cloth. 

3.   The best and most comprehensive studies of this that I have seen were done by Boeing aircraft.  Their standard is that you should remove particles down to 10% of the tightest dimension.  If you grind to 0.001” then you are concerned about anything larger than 2.5 microns.  

4.  At this level of filtering you are also removing tramp oils and greases since they naturally form larger globules than grinding oils. 

5.  Many individual bacteria and fungi are one micron or larger.  They all form colonies large enough to be filtered out at this level.   

6.  The laboratory is Spectra Labs in Tacoma, WA.
