they also sell a air dryer for air brushing that fits a roll of toilet paper I bought one at a yard sale years ago cant locate it at the moment to show ya works great
Thats a Motorguard brand filter, I use to use one it worked well but being made of cast aluminum it rotted from the inside... Wish it were made of plastic...
I've got an intercooler between the pump & tank, plus a copper pipe air cooling tower & a desiccant filter at the tank outlet plus a dual 3 micron filter...
