Our Specialized custom built filters are manufactured using premium grade materials and quality tested by us at various stages of manufacturing. Acknowledged for very high performance and long lasting features, these provide maximum life of the system to our esteemed clients.

SPANNKRAFT manufacture filters in dual configuration with each filter having two filter chambers. These filters operate continuously, One chamber is on-line and the other on standby allowing continuous operation when the first filter needs replacement or maintenance, an integrated rotary slide valve switches flow to the opposite side without interruption to flow. This enables a system to work continuously without interruption or shutdown.

And no 'down time' during routine maintenance. Change-over between on-line and standby is achieved by utilizing the integral ball valve system, which is controlled by a single lever.

The SPANNKRAFT Duplex filters is our standard cast/fabricated design and build according to ASME standards.which utilizes integral interlinked rotary slide valve for the changeover mechanism, can be mounted into suction, pressure or return lines and are designed for continuous filtration without system shutdown. Replacing the filter element is easy. Simply open the shut-off valve for pressure equalization then switch the filter to the opposite side.

Advantages of the Duplex Filters :
• Rotary slide valve system provides positive seal and Max. Flow.
• Element cleansing and maintenance whilst on-line.
• Large filtration area with easier different rating filters elements.
• Single lever operation for safety and simplicity.
• Competitively priced within its field.
