If you’re even an occasional visitor to the EXAIR Blog, you’ll know we like to write about compressed air filtration. One reason is that many of our products have relatively small passages that can become fouled with dirt from the compressed air supply, and performance will suffer. Even if you find yourself in that situation, though, the good news is, it’s easy to clean many of those products…worst case, some disassembly is required, but we’re here to help with that if needed.
The more pressing reason for many users is, whatever’s in your compressed air is going to get on whatever it’s coming in contact with. That means if you’re blowing dirt or water off a part with a Safety Air Gun, you could be blowing dirt, or water ONTO it if you’re not using proper filtration. Clean, moisture free air is a MUST for a lot of Line Vac Air Operated Conveyor applications where exclusion of contamination (food and pharma, we’re looking at you) is critical. It’s also quite important to Cabinet Cooler System applications – dust, water, and electronics DON’T mix.
That’s why all EXAIR Intelligent Compressed Air Product Kits include a Filter Separator with a particulate element to remove solids, and a centrifugal element that spins out any moisture in the air flow supplying the product. Sometimes, though, another contaminant may be present, and may need to be addressed: oil.
Oil is often introduced into a compressed air system on purpose, via a lubricator installed in the supply line to pneumatic tools, to keep their moving parts, well…moving. This is generally not a problem, as long as the lubricator’s downstream line only leads to said tools. The most common method for UNWANTED oil to enter is from the compressor. This happens when internal parts start to wear (like the piston rings of a reciprocating compressor,) allowing oil from the gearbox into the air side.
Just as water & dirt in your air will get on whatever you’re blowing onto, so will oil. That’s where our Oil Removal Filters come in. The coalescing element removes any trace of oil from the air flow, and also provides additional particulate filtration to 0.03 microns.
If you want to get the most out of your compressed air system and the devices it operates, give me a call.
