Loving Pets Acurel LLC Premium Activated Filter Carbon Aquarium and Pond Filter Accessory, 90-Ounce
Good for vaccum pump oil filtration
I use this product for a rather unconventional purpose, I filter vacuum pump oil with it. It’s primary purpose for me is to eliminate acids in the oil which come from the food processed in the freeze dryer. Vacuum pump oil isn’t cheap so being able to reuse it is a big bonus for me. When used with layers of filter material to eliminate particulate matter the charcoal nicely removes the acids and extends the oils life by months.
Two items of note here, there is a lot of dust which when the oil passes through it remains in the oil so I need another cycle of filtration to remove the dust but this is charcoal, you can’t really expect it to be dust free as that’s part of the nature of the product. Secondly, the kernel size can vary widely, there is no real consistency.
I’m using it for a purpose the manufacturer probably never imagined it would be used for, and it performs adequately. If I can find a product with a more consistent kernel size I would be happy but otherwise I will buy again.
