AirGap isolation

AirGap isolation
AirGap isolation – three Air tubes and foil .

‘AirGap’ isolation is a technique when Air is used to insulate an audio cable. This is achieved by isolating the cable from external interference. A Power cord, Interconnect cable, and Loudspeaker cables are items which benefit from this technique. 

Audiophile AirGap isolation

This process is similar to double glazing. Double glazing is used to insulate the interior of a house to keep it warm. By Insulating the interior, the house is isolated from external noise and vibration. When triple glazing is used, the results are even better. And in the same manner, audio cable isolation is necessary to reduce the effects of external vibrations – read more

Two meter Power cord
AirGap steps

The picture shows a white power cord running from left to right. Over the power cord, runs a layer of black material called CanuFlex PE-HB. This material has a very fine ‘mesh’ which is used to trap pockets of air. 

The CanuFlex PE-HB is covered with a green sheathing material DeRay-PBFSP. The material is slowly heated to a predetermined temperature. As the DeRay-PBSFB contracts, air is trapped and insulation is formed around the cable. A second layer is added when the process is repeated. A third layer can be added if necessary

The ‘AirGap’ isolation process makes an audio cable perform better. This is because the cable is isolated from external vibration and interference – read more

The Composition ~

Perkune audiophile ‘AirGap’ insulation has over 720 pockets of trapped air per square inch. These pockets of trapped air are in the material which runs around the entire length of the cable. 

The example ~
  • A Perkune audiophile power cord has a diameter of  9.0 mm.

After three levels of isolation, the power cord diameter increased from 9.0 mm to 15.0 mm.

An increase of 40% which gives excellent results in cable performance.

The Power cord is flexible and easy to use.

The results of AirGap isolation
  • First level ~ 17,280 pockets of ‘trapped’ Air.
  • Second level ~ 34,560 pockets of ‘trapped’ Air.
  • Third level ~ 51,840 pockets of ‘trapped’ Air.
  • The results are with a two-meter Power cord. 
Aluminum foil used for excellent sound insulation

Noise is not only a major burden but also a health hazard. This is why in the construction sector and in the industry and many other areas a lot of attention is paid to noise protection. Aluminum foils provide better sound insulation and help to eliminate noise sources. They reliably improve fire and moisture protection at the same time.

Aluminum foils ability to absorb sound allows unwanted noise to be picked up directly at the source and prevent its further propagation. Aluminum foil offers 85% effect as a noise insulator. Which means, only 15% of the respective sound passes through it and an ideal component for use in audio cables.

Power cord – Tip to Tip

Power cord insulation is taken from inside the top plug to the bottom plug. The insulation is also taken to the termination screws. This gives the ultimate connection and reducing the effects of mechanical and electrical vibration.

Interconnect cables – Tip to Tip
XLR connections

Working with interconnecting cables, the Canuflex PE-HB is taken over all connections. This is ‘tip to tip’ coverage which ensures a perfect isolation from external interference.

Loudspeaker cables – Tip to Tip
Antivibration connections

When applied to a loudspeaker cable, the Canuflex PE-HB is taken over all connections. This is giving ‘tip to tip’ coverage. Which ensures a perfect isolation from the effects of mechanical and electrical vibration.

The ‘AirGap’ isolation process can be applied to any cable where isolation is required. The performance is greatly improved by using these techniques regardless of system price.

I have been testing for months and have excellent feedback from my colleagues and customers. The results inspired me to improve the range using the ‘AirGap’ isolation and Anti-vibration technique. A person is now able to hear more of the musical presentation than ever before, which in itself is inspiring!

    1. Hello Alan

      It is actually Anti-Vibration that I am working on in this project. I am testing several
      different types of material for their Anti-vibration properties. When I find the material
      that I am happy with (which does not have an exorbitant price) I will add it to my range of
      cables because this is something that is overlooked in the audio world. In fact, there are
      only a few companies that have addressed this issue and able to offer a product but at a very
      inflated price.
      My plan to have something by the end of November /beginning of December and it will be worth
      waiting for!

      best regards


    1. hello Bishop

      This is from old school times where it was found that Air is an excellent insulator
      and it was applied to different applications – there are now quite a few audio cable
      companies who picked up on this idea and are using it very well for cable use
