Flat Duct for Underfloor Air Distribution / Underfloor Supply Flat Duct

Flat Duct for Underfloor Air Distribution — Underfloor Supply Flat Duct

A flat duct for underfloor air distribution. Its shallow 130 x 30 mm section is deliberately chosen so the duct can sit inside the floor build-up without raising the finished floor level. Air is delivered to low-level supply terminals, which suits underfloor air distribution (UFAD) strategies in residential and light commercial spaces.

• Low-profile underfloor routing — no impact on finished floor level
• Compatible with underfloor supply terminals — works with long-slot floor outlets
• Suits UFAD layouts — designed for low-level supply strategies
