OPERATION

The Duplex Filter 2.04.5 allows change-over during operation without pressure-loss. The filter is compact

and easy to maintain, requiring only manual cleaning when maximum allowable pressure drop is reached.

When maximum pressure drop is reached the standby filter chamber is brought on line simultaneously as the

dirty one is isolated by means of the change-over valve. After venting, the dirty element can be removed, cleaned

and refilled to be the standby filter chamber.

OPTIONAL ACCESSORIES

Differential pressure indicator type4.36 can be supplied fitted at factory.

The filter elements can be fitted withmagnetic bars.
