Removing water quickly is very important because the longer a harvested plant or compound retains water, the higher the chance it has of spoiling, losing nutrition, and losing potency.
I've also added an oil catch can that does a wonderful job of trapping oil vapor exiting the exhaust of the pump. Now instead of coating the area in a fine oil mist, the oil settles into the can. The clear tube on the side of the can lets you know how full the can is.
