Tentec Airbac-serie

Airbac-series – Topside tensioners

The Airbac series of topside tensioners is a further development of the standard CTST pensioner series. The Airbac series has a unique ‘piston retract’ system which increases the simplicity and speed of work. The Airbac series can be used in pressure-containing applications, steel constructions and machine building. The series consists of six models for the bolt range M20 to M100, which is suitable for flanges according to the guidelines ANSI B16.5, ANSI B16.47 Series A, MSS-SP44, API-6A and API-17D. The Airbac series has a maximum working pressure of 1500 bar.
A kit consists of a load cell with a corresponding range of pullers, bridge pieces and utility rotating sockets for the various bolt sizes (conversion kits). Metric and UNC-/UNF kits are available as standard. Specials can also be designed on request.

Features: (extra compared to CTST series)

  • Airbac Piston retract: Unique to the Airbac series is its piston retract function. Unlike spring return systems, the Airbac Piston Retractor works with a compressed air chamber to push the piston back to its initial position. This works more than 3 times faster than spring return systems. With a full air pressure charge of 5 bar, up to 800 cycles can be made before it needs to be refilled.
  • Lightweight: Airbac technology makes the tensioners 20% lighter than spring return systems.
  • Nickel-plated coating: The Airbac series is standard equipped with a nickel-plated coating which is many times more resistant to corrosion.
