The Superior® 25-S "High Output" Air/Smoke Blower is engineered for efficient and economical smoke testing of sewer lines to detect sources of inflow and leaks. Also for fast ventilation of sewerage collection systems and closed areas.

The blower features a single unit sturdy metal construction complete with carrying handles for easy handling, beltguard and 27 1/2” custom fiberglass base, eliminating need for separate manhole cover.
