Our Products

Alignment Joints

3D Pneumatic Coupling
Airtomic’s patented pneumatic joint technology is based on allowing the greatest degree of freedom on motion, eliminating the potential for damage to ducts/tubes or joints. Don’t replace joints, just replace sealing rings. Airtomic’s alignment Joints… there is no comparison. We keep your ducts flying.

  • Lowers operating costs (less inventory required)
  • More efficient (fewer replacements)
  • Less maintenance; more uptime
  • No catastrophic failure

Airtomic’s alignment joints are the only coupling in the industry which provides true 3 dimensional freedom of movement. Axial, offset (angular), and torsional movement, virtually eliminates load on adjoining structures. Couplings are equipped to handle vibration, offset, torsion and thermal growth.

Spherical Angulation Joints

360° Torsion
Airtomic’s pneumatic joint technology is designed with a singular purpose:

Eliminate the potential for damage and keep your ducts flying.

  • Unlike legacy technologies on the market, Airtomic’s pneumatic joints do not have to be replaced.
  • Address wear-and-tear issues by simply replacing the sealing rings and you’re back in business.
  • Flexibility allows for thermal expansion with maximum degrees of axial, angulation, and total free torsion.
  • Couplings are equipped to handle loads while eliminating the concern of damaging adjoining structures.
  • Resistance to movement can easily be increased or decreased as required
