– Sold Out

The Viair 5-gallon 4 port air tank is a precision-welded tank that features two 1/4" ports and two 3/8" ports as well as an anti-corrosion coating. This air tank is rated for up to 150 PSI and is perfect for most mobile pneumatic applications.

As an important safety precaution,  a safety blow-off valve should be installed with any air system. A safety blow-off valve is designed to keep the system from over-pressurizing and to prevent damage to other components. It is suggested to use a safety blow-off valve with a PSI rating between 25-35 PSI higher than the maximum pressure of the pressure switch.

For example, 150 PSI systems require a 175 PSI safety Blow-off and 120 PSI systems require a 150 PSI safety Blow-off.

Great product

This is a really good tank only thing I wish I would have done is got more holes so I had more places to put things. But I made it work.
