Page 3: Introduction
During the design phase, INTEWA studied world rainfall data. Purain filters have been designed to collect rainwater especially from “light” rainfall events and use the “heavy” events for self-cleaning. -

litres of rain falling on your roof, your filter will collect 98 litres of it. PURAIN rainwater filters are designed to filter rainwater coming off roofing made from clay brick, shales, tiles, metal, glass or concrete stone. Different sized PURAIN models can be installed covering roof areas up to 15,000 m². - Page 5 PF300-150 Calmer is an integral component to “best practice” rainwater collection ensuring that incoming rainwater to the tank is calmed, ensuring sediment stirring is kept at a minimum PR-RSDS-150-200 back-flushing nozzle for PR-150-S and PR-150-S o.SK For large filters, we recommend the back-flushing nozzles to minimize the intervals of manual maintenance.

Page 6: Technical Data
Technical data As a general rule, the choice of a PURAIN rainwater filter is made based on the diameter of the rainwater collecting pipe stipulated by the building architect or water engineer e.g. DN150 (160mm) = PR-150-S. If the diameter of the planned collecting pipe is not known, then you can refer to the following table. It gives an overview of the dimensions of these rain water connection pipes, as per DIN 1986, with measured rainfall yield indicator of r = 300 l/s ha and a slope of 1.5%. -
Page 7: General Installation Instructions
5. General installation instructions IN-TANK INSTALLATION • The filter is best installed inside the tank, if possible, under the inspection lid for most efficient functioning (PR150-S version); • The filter must be installed with a slope of 2 – 5 % from inflow to outflow side;... - Page 8 WALL-MOUNT INSTALLATION Should it not be possible to mount the PR-150-S inside the tank, it can be mounted above the tank (see below illustration). The version used for wall mounting is PR-150-S oSK. NOTE: An out-of-tank installation of this nature requires both PR-150-C cover and PF-300-C cap to keep additional dust and debris from entering the collection chamber.

SUB-SURFACE INSTALLATION PR-150-S oSK version can also be in-ground mounted. NOTE: The unit is ribbed and made from sturdy HDPE. If the earth is well compacted around the filter and a man- hole is used, a carrying capacity of several tonnes can be realised. NOTE: PR150-S oSK version can also be sub surface mounted within a purpose- built sump. -
