The Superior® 20-S Manhole Air/Smoke Blower is designed to inject dense white smoke into sanitary or storm sewers for quick, definitive detection of unwanted inflows and leaks from roof downspouts, drain tiles, leaking manholes, cellar drains, broken laterals, sump pumps, abandoned sewer lines, unconnected sewer lines, cross connected sanitary and storm sewer lines. Model 20-S features an auxiliary outlet with removable cover and adjustable damper for directing air/smoke through the base or through the auxiliary outlet to which an 8" flexible duct can be attached. The Superior® 20-S uses Superior® Smoke Candles (sold separately). Powered by a dependable 3.5hp Briggs & Stratton gasoline engine, the blower generates enough pressure to distribute smoke evenly through sewer mains and laterals to reveal inflows and leaks, but not so much pressure as to blow out water traps. The blower housing and belt guard are constructed of heavy-gauge painted mental designed to withstand many years of rigorous field use. Fully assembled, the 65-pound unit features two sets of carry handles and is balanced evenly for easy, two-person carrying. A 27 1/2" diameter custom fiberglass base fits snugly into standard manholes eliminating the need for adapters or a separate manhole cover. Standard capacity is 1800 CFM at 1.7-inch static pressure. An optional Pulley Kit (sold separately) enables two different high-flow capacities for larger or longer sewer systems: 4200 CFM at 3.0 static pressure and 4000 CFM at 4.0-inch static pressure. The Superior® 20-S Air/Smoke Blower is designed to use only 3C Superior® Smoke Candles, not smoke fluid. If you wish to use Superior® Smoke Fluid, choose Model 20-L Superior® Air/Smoke Blower instead. Superior® Manhole Air/Smoke Blowers are proudly made in the USA.
