Manhole Adapter

Manhole Adpater

Manhole Adapters are a great way for utility companies and more to place blowers/exhausters safely atop of manholes securely.  These adapters allow negative pressure fans to pull smoke, toxic fumes and more from deep in the manhole.

These rugged aluminum adapters come in 4 sizes and sit in manhole rings to provide a stable mounting surface for box fan.

Note: Not for use if manhole is the only means of egress.
