Proco Style 520
The Proco Style 520 Ducting Flexible Connector is an economical, integrally flanged design, used primarily for the reduction of fan vibration. The fan/duct connector features a U-shaped design configuration, with a minimum of one to two plies of reinforced fabric that has been vulcanized into a homogeneous product. The finished thickness can be selected from 3/16”, 1/4”, or 3/8”. The Style 520 is manufactured with continuous corners; no splices are made in the corner areas.

Lateral offsets shown above are based on movements prior to axial compression. Greater lateral offset may be obtained if the fan/duct connector encounters simultaneous compression . Axial extension may be increased by pre-compression of the fan/duct connector during installation. Any pre-compression of the fan/duct connector will equally reduce the rated axial compression movement.
