Fan Flex Connectors for Industrial Fans and Ductwork
Air Systems fabricates custom fan flex connectors in-house for fans, ductwork, heat exchangers, ovens, RTOs, and dust collectors, with flex materials rated from -40°F to 1500°F.
Each connector absorbs fan vibration and thermal expansion between fan outlets and ductwork, with approval drawings returned in 1 to 2 days.

Fans, ductwork, heat exchangers, ovens, RTOs, and dust collectors that need vibration isolation and expansion joints to absorb thermal movement between fan outlets and ductwork.
How Fan Flex Connectors Are Built & Configured
Fan vibration through rigid duct connections fatigues flanged joints, wears bearings, and creates noise. We fabricate flex connectors as expansion joints that absorb vibration and thermal movement, from 6" to 89"+ diameter or 6" x 6" to 120" x 240"+ rectangular.
- 01 EPDM to 300°F, Texfilm to 650°F, Padmaster to 900°F, and Extreme Hi-Temp to 1500°F
- 02 Straight or offset transitions, round-to-round and round-to-rectangular
- 03 Carbon or stainless steel flow liners for abrasive airstreams
- 04 Offsets from 1/2" to 2", with 1" standard
- 05 Replacement flex belts in any size or shape for existing duct flanges
- 06 Leak-proof one-piece design for applications up to 650°F
Why Air Systems
Fan flex connectors fail when the flex material's temperature rating is exceeded or the flange geometry doesn't match the connected equipment. We select the flex grade for your operating temperature and airstream.
Fabricated in-house for fans, ductwork, heat exchangers, ovens, RTOs, and dust collectors — offset custom builds available to 1200°F, shipped nationwide.
