    Spool tank is 👏 Awesome. Minimal spool rolling resistance with bearing mounted rollers. Running my tank with printer box fan exhausting through spool tank. Adding a few desiccants to the bottom of tank also works well as the tank is well sealed. Very happy with this product and customer support….. Well Done folks👍
