BWT Multipur AP

BWT Multipur AP 65–150 is an industrial filter with automatic backwash by time and differential pressure. It is for treating cold drinking water at the site inlet.

The mesh element retains insoluble impurities from 100 µm (optionally 200 µm): rust, sand and silt — and protects later stages and equipment from corrosion.

The brass body resists corrosion. Treated-water supply is not interrupted during backwash. Installation needs a drain and inlet pressure of at least 2.5 bar.

• Scheduled and pressure-triggered auto-backwash
• 100 µm filtration, optionally 200 µm on DN 65 and 80
• Flanged connection DN 65, 80, 100, 125, 150
• Brass body CuZn36Pb-C / CC770S
• Reinforced metal mesh screen
• Air gap on the drain — protection against bacteria flowing back
• Two gauges on inlet and outlet
• Lower rinse-water use thanks to a large filtration area

• Hotels and commercial sites
• Industrial cold-water inlet
• First stage before softening and UV

• Connection to a drain or sewer is required
• Minimum pressure after the filter for backwash — 2.5 bar
• Replace the filter element every 6 years
• Replace seals every 3 years
