  • Sealing Efficiency up to 99.9% with seals & 100% with Seal Air Fans.
  • In – House design, manufacture & testing
  • Highest Quality Workmanship Guarantee
  • Designs for all applications from flow control to 100% Isolation of the duct
  • Maintenance free Bearings
  • Alloys used include SS316Ti, SS310. Inconel 625, Incoloy 800H, Monel etc.
  • Designed for Circular as well as Rectangular ducts of all sizes for any duct orientation
  • Completely factory assembled & tested eliminating the need for on-site adjustments
  • Suitable for actuation with Manual, Electric, Pneumatic & Hydraulic actuators

Broad range of well-proven designs is available in various materials to suit any temperature, pressure and corrosive condition. For even higher temperatures, special provision can be made in the design such as Refractory / Ceramic Fiber Lining with superior metallurgy. Gas tightness requirements of up to 99.98% are routinely met and Zero gas leakage is guaranteed when air sealing is used. To suit the service requirements a range of sealing arrangement options such as Omega Seal, Bulb Seal, etc. can be incorporated of various materials along with a provision of Seal Air System.
