Pressure reducer FD 10 and FD 5

The IAG FD 10 and FD 5 represents an attractive alternative to conventional pressure reduction systems. The unit automatically reduces any intake pressure of up to 60 bar to a level of 10 or 5 bar – with no loss in flow rate. The pressure reduction system also closes automatically when the supplied unit is shut down, without any need to drain water. This system eliminates any pressure overload to the attack line, even when no water is discharged. A pressure relief valve is integrated in the output side to provide additional safety.

FD 10 and FD 5  are used in systems with a high output pressure, such as snow-making equipment and high-pressure lines, and can be used in conjunction with conventional firefighting equipment.
