The Pentair G-30-1905NCP Lower Diffuser System<\/strong> is the genuine replacement lower diffuser assembly for Triton NEO 19″ sand filters. Housed at the bottom of the filter tank, the lower diffuser plays a vital role in distributing water evenly across the full cross-section of the sand bed. Even, low-velocity distribution prevents channelling \u2014 where water carves a direct path through the sand rather than flowing through it \u2014 which would significantly reduce filtration quality.<\/p>\n The G-30-1905NCP<\/strong> is supplied as a complete lower diffuser system including all internal distribution components. This means the entire assembly can be swapped in one operation without sourcing individual sub-parts, minimising filter downtime during a service.<\/p>\n A cracked or degraded lower diffuser leads to uneven water distribution, reduced filtration effectiveness, and increased backwash frequency. Replacing it with this OEM part restores optimal flow dynamics and keeps your sand filter running at factory specification.<\/p>\n The Pentair Triton NEO Lower Diffuser System 19″ (G-30-1905NCP) is the original replacement lower diffuser assembly for 19″ Triton NEO sand filters. The lower diffuser distributes incoming water evenly across the sand bed from below, maximising contact time and filtration efficiency. Supplied as a complete assembly ready to install.<\/p>","protected":false},"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"bwfblock_default_font":"","inline_featured_image":false},"product_brand":[38],"product_cat":[1794],"product_tag":[],"class_list":["post-12734","product","type-product","status-publish","product_brand-pentair","product_cat-sand-filters","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":{"pph_product_template":false,"pph_extra_parts_check":"","pph_spare_parts":null,"pph_extra_spare_parts":null,"extra_product_tabs":null,"main_product_link":null,"restock_info":"","exploded_view_link":"","details_product":[{"text_details_type":"yes","text_details_product":"Complete assembly \u2014 all diffuser components included for a single-operation swap"},{"text_details_type":"yes","text_details_product":"Original Pentair part for guaranteed compatibility with Triton NEO 19\" filters"},{"text_details_type":"yes","text_details_product":"Restores even water distribution across the sand bed for optimum filtration"},{"text_details_type":"yes","text_details_product":"Prevents channelling and maintains low backwash frequency"},{"text_details_type":"yes","text_details_product":"Compatible with both standard and ClearPro 19\" Triton NEO models"},{"text_details_type":"no","text_details_product":"Requires partial disassembly of the filter internals for installation"},{"text_details_type":"no","text_details_product":"Sized for 19\" tanks only \u2014 not compatible with 24\" or larger Triton NEO models"}],"details_product_exploded":null,"pph_card_badge_use_custom":false,"pph_card_badge_text":"","pph_card_badge_background_color":"#ADC2F7","pph_card_badge_border_color":"#ADC2F7","pph_card_badge_text_color":"#2B46AB"},"yoast_head":"\nComplete Assembly<\/h3>\n
