For plant operators, uninterrupted system availability is a top priority to ensure consistently high productivity. The Type W-DF duplex filter was specifically developed to meet these requirements.

As a switchable duplex filter in a two-line operation, it enables efficient filtration even during cleaning or maintenance – without interrupting the flow of the medium.

Reliable removal of foreign particles

The duplex filter safely removes foreign particles from various media, such as:

• Lubricating oil
• Water
• Similar liquids

The Type W-DF duplex filter is specially designed for continuous filtration in industrial processes and reliably protects downstream plant components.

Switchable two-line operation for maximum operational safety

During normal operation, one filter chamber is active while the second filter chamber

• is filled with the medium
• contains a clean filter element
• stands ready as a reserve

Once the active filter element becomes contaminated, the system can be manually switched to the reserve chamber. Overlapping switching between the two filter chambers ensures that the medium flow always remains uninterrupted.

Maintenance-friendly and efficient

After switching, the contaminated filter element can be:

• removed
• cleaned or replaced
• reinstalled

This makes the chamber available again as a reserve for the next switch. The Type W-DF duplex filter thus optimizes cleaning intervals, increases system availability, and enhances overall efficiency.
