Safeguard Crews with Confined Space Ventilation

Darley’s Confined Space Ventilation lineup unites portable blowers, conductive ducting, and innovative Saddle Vent™ entry systems to create safe, breathable work zones in manholes, tanks, tunnels, and vaults. Compact 8-inch Nano Ventilators move high volumes of air through 25-foot ducts, quickly diluting toxic gases and heat so crews can focus on the mission rather than the atmosphere. For continuous airflow during entry and exit, Saddle Vent kits position the duct at the rim, bundling manhole-entry devices, 90° elbows, and quick-couple canisters for rapid, tool-free setup. Static-dissipating hoses, GFCI-compatible power options, and accessories for UB-series blowers help departments meet OSHA and NFPA standards, minimize heat stress, and ensure every responder returns home safe.
