DDF-FD - Drum Displacement Diffuser
Cylindrically shaped displacement diffuser for placement on the floor. Connection from above or below. The SMARTEMP Drum Displacement Diffuser, type DDF-FD, discharges low velocity supply air with fixed horizontal discharge direction in a radial pattern for displacement airflow supply in commercial spaces. Air supply across inner and outer perforated cylinders provides uniform, low turbulence discharge across the entire perforated drum-shaped face.
