Design notes

Short build lengthIdeal for risers and plant rooms where space between dampers is limited.
High pressure coefficientSmall diameter ratio accelerates flow and raises pressure.
Low noiseCompared with an axial fan of the same duty, sound power is lower.

Options

Explosion-proof
VFD
Silencer

Applications

Tight risers
Retrofit projects
Hotel and museum ventilation
