UFDC Passive Single Diffusers

Passive floor-mounted diffusers with direction and flow control for supply air in pressurized raised floor systems.

Overview

• Installed in the floor supply airway, where pressurized air maintains consistent flow

• Swirl discharge pattern ensures effective air mixing and reduced stratification

• Airway depth: 12–18 inches (305–457 mm)

• Integrated dirt-holder below the flow adjustor captures debris from the floor, accessible from the top for easy cleaning

• Manual flow adjustor allows simple increase or decrease of airflow by rotating the dirt holder clockwise

• Designed for VAV floor applications with passive air terminals, circular control damper, and 90° rotational angle range

• Hydrostatic control air plenum delivers direct access airflow to the occupied zone without requiring anemometer pipes or tubes

Features

• Durable casing: Gauge 18 (1.2 mm) galvanized steel construction

• Premium grilles: Heavy-duty extruded aluminum linear grilles

• Optional heat inlet available for enhanced comfort
