## Overview

The 25-S Manhole Air/Smoke Blower is engineered to efficiently distribute dense white smoke through sewer systems, enabling quick detection of surface water inflow, a major contributor to sanitary sewer overflows. With a robust Briggs & Stratton 3.5 HP engine and a user-friendly design, this blower is perfect for professionals seeking reliable performance and ease of use.

## Description

The Superior 25-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. The Superior 25-S features an auxiliary outlet with removable cover and adjustable damper to direct air/smoke through the base or the auxiliary outlet which can fitted with 8" flex duct. 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. High-volume capacity, 4000 CFM at 1.7-inch static pressure, for longer or larger sewer systems. The Superior 25-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 25-L Superior Air/Smoke Blower instead. Superior Manhole Air/Smoke Blowers are proudly made in the USA.
