This unassisted, fresh-air supply architecture is heavily utilized for continuous entry and maintenance work inside oxygen-deficient or highly toxic confined spaces, such as tanks, reservoirs, silos, and deep wells.
⚙️ Purpose and System Integration
When a job site requires two operators to work simultaneously inside the same confined environment, the standard single-user DUCT ECO framework must be expanded. The 14016 ECO Set acts as the necessary expansion hub. It bridges the fresh-air source to a second user without requiring an entirely independent air collection system, branching directly off the main manifold setup.
📦 Component Architecture
The kit is configured as a complete terminal operator assembly, including:
-
Full-Face Mask Assembly: Bundled with a premium Spasciani panoramic full-face mask featuring a wide, distortion-free field of view and secure seal ergonomics.
-
Respiratory Breathing Tube: A heavy-duty, corrugated connection hose designed to withstand kinks and maintain a constant, uninhibited airway under tight working positions.
-
Comfort Harness & Belt System: A specialised weight-distribution harness built to comfortably anchor the corrugated breathing tube securely across the user's back and hip area, preventing physical pull on the face mask connection.
- Manifold Connection Interface: Integrated gaskets and bayonet-style connector fittings required to split air distribution cleanly from the primary supply lines
