Industrial Grade, All Welded Construction

Applications
  • Fan inlets and outlets
  • Pressure blower inlets and outlets
  • Baghouse inlets and outlets
  • Scrubber inlets and outlets
  • Dryer outlets
  • Stack inlets
  • Gas turbine intake systems
  • Ventilation and process ductwork
Model 513 rectangular EPDM acoustic flexible connections
  • Tough, 1/8" thick, layered EPDM flex membrane with internal nylon scrim for superior tear strength
  • Resistance to ozone and UV exposure, and cold cracking makes it ideal for outdoor use
  • Good for airstream flows to 6,000 fpm and pressures from -30" wg to +120" wg
  • All welded, matched and drilled flanges
  • Backing bars fastened in place with zinc plated hardware
  • Acoustically rated design with absorptive acoustic pillow and acoustic outer barrier
Model 514 rectangular EPDM acoustic flexible connections
  • Identical construction to Model 513 flexible connections, with an aerodynamically designed, protective metal flow liner
  • Good for airstream flows over 6,000 fpm and pressures from -120" wg to +120" wg (with a flow liner)
  • Double deflectors are also available for extra flow protection and noise reduction
