HVAC Guys Flow Tabs - Each Tab Treats 3 Ton Systems up to 3 Months - Equivalent to 324 regular hard tablets! HVAC PROFESSIONAL FORMULA: Supercharge your air conditioner and refrigeration system maintenance with our HVAC Guys Flow Tabs with “Gel Lock” Technology. Used by fellow HVAC professionals, our Flow Tabs are specially formulated to effectively keep drain pains free from slime, smells, and water overflow. Great for central air conditioners, ductless mini-splits, heat pumps, refrigerators, refrigeration systems, and dehumidifiers. Designed for professional use. HELPS PREVENT ODORS AND WATER OVERFLOW DAMAGE: Over time, slime in the drain pan can cause foul smells. If left untreated, the drain line can also become clogged, allowing water to overflow and cause expensive property damage. Our Flow Tabs are an easy solution to effectively prevent the buildup of scum and drain-clogging slime in air conditioner condensate drain pans. SPECIAL "GEL LOCK" NO-CLOG TECHNOLOGY: Most pan “tablets” are hard pills that can move around the drain pan. They can clog your drain pipe or be flushed out when the drain pan fills. Flow Tabs are made with a unique GEL LOCK technology that, when wet, locks the tab gel into place. It will not move around or clog the drain. EASIER TO USE THAN REGULAR DRAIN PAN TABLETS: Set it and forget it! No more adding handfuls of tablets every month! Each Flow Tab will dissolve completely at a consistent rate over 3 MONTHS for systems up to 3 TONS to keep an ENTIRE pan clean, free flowing, and without odor. This is equal to more than 18 regular hard tabs (typically 2 or more regular tabs need to be added per ton every single month). An 18 pack of Flow Tabs is equivalent to around 324 regular hard tabs. 100% SATISFACTION GUARANTEE: We stand 100% behind the quality of our products.
