NO Filter Needed! Ingersoll Rand Total Air System Rotary Compressor 

The Ingersoll Rand R4i Rotary Compressor with the Total Air System filters and conditions the air. We're running our complete 2,000 square foot shop without filters in the air lines. We've been running the Ingersoll Rand R4i with the Total air system, and we have yet to find any moisture in our lines, tools, or our work.
We consistently use air tools in the shop, including impacts, sanders, blow-guns, and paint guns.
Yes, the step up to a rotary compressor with the TAS (Total Air System) is a bit more, but you no longer have to worry about your desiccant filter filling with moisture. With only a regulator on our air lines, we have water traps at every outlet, and we never even have a droplet of water at any trap. We're also in Florida heat and humidity, so we know how bad moisture can ruin your day.
Check out the Ingersoll Rand R4i rotary compressor and Total Air System. You can get these ranging from the R4i, 5hp, all the way to the R11i 15hp.
