Enclosed switchover with brass internals and pressure switches for high flow industrial gas applications

The 636 Series AutoSwitch HF provides a continuous supply of nonflammable industrial gases at a constant delivery pressure from two high pressure banks. Pressure switches enable visual alarms and an optional remote alarm to notify the user of the need to replenish a depleted bank. The CONCOA 636 Series AutoSwitch HF is designed to be used in conjunction with the CONCOA Altos 2™ remote alarm to provide audible and visible warnings of cylinder depletion.
