Optrel 4556.030 - Swiss Air Replacement Harness
Available from stock. This is the standard harness with clip buckle at the front. If you are replacing your current harness and are using the extension straps you will either need to buy new extensions or remove and reuse the extension pieces.
Take a note of the two possible positions for where you have installed your Swiss Air filter unit to locate it at the same level on your new harness.
