The filter collector (FS) and 
standpipe filter collector (STFS)

Cleaner rainwater for use in the house

• For fitting into the vertical rainwater downpipe
• For roof areas of up to about 150 m²
• The uunique construction of the vertically placed fine filter washes out large and small dirt (larger than 0.28 mm). Moss, leaves and insects are automatically
• Absolutely safe function
• 90% of the water is extracted
• Meets DIN 1986
• Low maintenance

The filter collector (FS)

• The rainwater coming from the roof through the downpipe is drawn through the vertically placed stainless-steel fi lter insert by adhesion forces, it then is led through the outlet (DN 50) to the storage cistern.
• Because of the unique construction (German patent no. 3812136) the dirt particles contained in the rainwater (larger than 0.28 mm) are rinsed directly into the drain with the remaining rainwater. More than 90% of the water passing through the FS is fi ltered and collected by this principle.
• The full cross-section of the rainwater drainage system remains continuously open in the FS and STFS systems. There are no restrictions or obstructions in the appliances on which rainwater can collect. This is especially important in hail storms and torrential rainfall. In such cases 50% of the fi ltered water is still transferred to the storage cisterns. Excess rainwater is led directly to the raiwater drain or soakaway.
• Pitched roofs of slate, clay or concrete tiles are most suitable for collecting the rainwater. Planted roof areas are less suitable because of the low water-collection effi ciency and the brown colour imparted to the collected water. Non-sealed asbestos cement roofs are less suitable, the fi bres of this roof covering tend to block the fi ne fi lter mesh.
• Resistance to corrosion and frost is absolutely guaranteed. The compact design allows simple and easy assembly on almost all rainwater downpipes.

The standpipe filter collector (STFS)

lt is a standpipe and filter collector in one and is an alternative to the filter collector, where this shall not be installed for technical or visual reasons.

The advantages of the STFS:
– Laying the cistern inflow below ground, i.e. no second pipe visible.
– Larger collecting space, and thus an even higher efficiency with heavy rain.
