The Hermesys GryphonX™ Armored Multi Size Bundle Duct is an armored microduct bundle combining two duct sizes in one sheathed assembly, purpose-built for structured air-blown fiber (ABF) networks. Its mixed-diameter layout lets a single duct run carry both trunk and distribution-level microducts together, simplifying civil works where multiple fiber paths need to be pulled through one conduit route.
Key Features and Benefits
- Mixed bundle of 4 large-bore ducts and 5 small-bore ducts in one sheath, letting a single installation carry both higher-capacity and lower-capacity fiber blowing paths without pulling separate conduits
- Corrugated steel tape armor under the outer sheath adds crush and rodent resistance for direct-buried and duct-bank installations
- LSOH (low smoke zero halogen) outer sheath keeps smoke and acid gas emissions low in the event of fire, supporting safer evacuation in enclosed or occupied installation routes
- PP inner sheath binds the duct bundle before armoring, giving the assembly a stable, round cross-section for consistent blowing performance
- Two ripcords under the inner sheathing allow clean, tool-light sheath removal during jointing and termination
- Wide -40°C to +70°C storage and operation range suits both harsh outdoor duct banks and enclosed environments
- High installation tension rating — 550 kg / 5.5 kN — supports long single-pull duct runs without exceeding the cable’s mechanical limits
- Outer sheath colour options (beyond natural) support duct-route identification and utility colour-coding conventions
Typical Applications
