Applications:
- For main trunk and return lines
- Vertical takeoff from supply duct to single outlet in order to compensate for misalignment
- Connecting lines from mixing boxes in the main trunk systems or directly from the plenum to room inlets or diffusers.
- Connecting lines to under-window perimeter units
- Connector to combination light troffers
- Connector from the low pressure side of attenuation boxes to diffusers
- Connector from hot and cold ducts to mix boxes on the high-pressure side of a dual duct system
Performance Benefits:
- Improved Airflow – Maintains a constant cross-sectional area throughout a bend with pressure loss comparable to die-formed elbows
- Flexible and Easy to Install – Will not kink on 90-degree bends making it easy to use in tight areas
- Economical Installation – Easy to field-cut to desired length eliminating waste and reducing handling costs
- Self Supporting – Semi-rigid construction eliminates sag and droop between connection points providing a neat finished appearance
- Corrosion Resistance – All metal construction will not rust or rot, and is impervious to damage by mold or mildew
- Fire Resistant – All metal construction allows continuous operating temperatures from 200 degrees Fahrenheit
- Quiet – Corrugated construction reduces the transmission of mechanical vibration and noise
