Series DF-60

Available in round or rectangular configurations, the DF-60 is designed for use in duct systems where pressure, abrasion and mechanical movement preclude the use of conventional ducting connectors.

Features
• Relative light weight
• Non-conductive
• Abrasion and corrosion resistant
• High fatigue resistance
• Wide material selection
• Movement achieved with relatively low force

Available in round or rectangular configurations, the DF-60 is designed for use in duct systems where pressure, abrasion and mechanical movement preclude the use of conventional ducting connectors. The external metal reinforcement and high strength synthetic reinforcing fabrics allow working pressures in excess of 25 PSIG. The wide arch design and rounded corners of the rectangular style allow for high movement capabilities while reducing fatigue due to flexing. Abrasion resistant rubbers allow the use of this expansion joint in applications such as discharge chutes, pneumatic conveyors and vibratory feeders. EVR DF-60 Expansion Joints are available in a wide range of elastomers and fabrics to suit most corrosive and temperature environments up to 400°F. To receive a design proposal, contact EVR to get a DF-60 Expansion Joint for your specific application requirements.
