Air Systems SV-189 Saddle Vent Confined Space Fresh Air Duct

Air Systems SV-189 allows unrestricted exit, entry & increases ambient light for confined space openings.

The original Saddle Vent by Air Systems has been in use all over the globe for 20+ years and makes it safer and easier to exit or enter confined spaces. The SV-189 occupies only 3 inches on 1 side of manhole openings & delivers fresh air to workers in confined spaces. By using the Saddle Vent, continuous ventilation to workers is enabled by eliminating the removal of the air duct every time someone needs to leave or enter, thereby increasing productivity and safety.
