Viair 5 Gallon Black 4 Port Air Tank
MORE AIR FOR MORE SCARE.
The Viair 5-gallon 4 port air tank is a precision-welded tank that’s built to last. With two 1/4" ports and two 3/8" ports, you’ll have all the airflow you need to power your mobile pneumatic applications. The anti-corrosion coating ensures that this tank will look as good as new for years to come. This air tank is rated for up to 150 PSI, making it perfect for most mobile pneumatic applications.
- Anti-corrosion coating
- Precision welding
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.
