The design model for PURAIN Rainwater filters comes from nature: At almost every course in a stream, you can see how the hydraulic jump functions. The water flows over one of the stones, smooth and rounded by the action of the water over time. The water flow is substantially changed by the height drop, from a sub-critical to a super- critical flow. At the bottom of the dip, the waterflow changes again to a subcritical flow in a process now commonly known as hydraulic jump. This resulting increase in water power forces any impurities over the next level and washes them away downstream.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePURAIN Rainwater filters for industrial, public or commercial buildings.\u003c\/li\u003e\n\u003cli\u003eThis series is developed for in tank installation, wall mounting or in a separate chamber\u003c\/li\u003e\n\u003cli\u003eFor discharge pipes up to DN300\u003c\/li\u003e\n\u003cli\u003eL x B x H:                                                      1786 x 385 x 866 mm\u003c\/li\u003e\n\u003cli\u003eD1 Intake:                                                     DN300\/Ø315 (LP*)\u003c\/li\u003e\n\u003cli\u003eD2 Clearwateroutlet:                                     DN200\/Ø200 (LP*)\u003c\/li\u003e\n\u003cli\u003eD3 Emergency overflow\/ Wastewateroutlet: DN300\/Ø315 (LP*)\u003c\/li\u003e\n\u003cli\u003eH1 Intake:                                                     499 mm\u003c\/li\u003e\n\u003cli\u003eH2 Clearwater outlet:                                    53 mm\u003c\/li\u003e\n\u003cli\u003eH3 Emergency overflow:                               228 mm\u003c\/li\u003e\n\u003cli\u003eΔh Height offset:                                            271 mm\u003c\/li\u003e\n\u003cli\u003eb Sealing collar:                                             13 mm\u003c\/li\u003e\n\u003cli\u003eWidth of wedge wire filter:                              0,8 mm\u003c\/li\u003e\n\u003cli\u003eEfficiency:                                                       98%\u003c\/li\u003e\n\u003cli\u003eMaterial:                                                          PE, NBR, Stainless Steel\u003c\/li\u003e\n\u003cli\u003eWeight:                                                           48 kg\u003cstrong\u003e \u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALOAQUA","offers":[{"title":"Default Title","offer_id":21296927041,"sku":"PR-300","price":5522.25,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1350\/6695\/products\/pr300.jpg?v=1467262729","url":"https:\/\/www.aloaqua.co.nz\/products\/purain-filter-dn300","provider":"ALOAQUA","version":"1.0","type":"link"}
