The Saddle Vent ventilator provides continuous access to the entry hole for either entry or egress. Traveling in and out of the confined space can now be done quickly and safely. The unit can be completely set up in less than five minutes. Eight inch air duct is installed on the bottom of The Saddle Vent and runs to the bottom of the manhole. This allows fresh air to be supplied to the workers and displace any harmful gases that may be deadly for the occupants. The use of the 90 elbow removes the severe kink in the air duct and allows for rotation of the intake duct to any desired position at the street level.
