Name: Ducted inline fans
Availability: InStock

Inline centrifugal duct fans that deliver centrifugal pressure capability in a straight-through duct casing. Twin City's Model BCS backward-curved high-pressure range covers 16.5" to 89" wheel diameters, airflow to 291,400 CFM and static pressure to 40" w.g., and is licensed to bear the AMCA Seal for both air and sound performance.

Used for toilet, kitchen and general extract, for supply boosting on long duct runs, and in fit-outs where there is no room for a fan cabinet. Because the fan sits in the ceiling void over occupied space, breakout noise through the casing usually decides the selection rather than the duty point — which is why an AMCA-certified sound rating matters more here than in a plant room.
