Before it is shipped, the flow characteristics of the Air Knife are tested. First, follow the disassembly procedure and inspect the Air Knife for dirt contamination. Cleaning guidelines can be found on the installation and maintenance sheet shipped with the Air Knife or the Adobe PDF version may be downloaded from the Literature & News menu on this website. Secondly, the Air Knife may not be receiving enough volume of compressed air. Don’t use restrictive fittings, undersized lines or filters that may not allow enough airflow into the plenum chamber of the Air Knife. Air Knives that are 18″ (457mm) or longer must be supplied at two compressed air inlets at opposite ends of the Air Knife. Thirdly, the screws may have been over-tightened during mounting or reassembly. Screws should be tightened snugly (7.5 ft/lbs).

I see your Super Air Knives come in off-the-shelf lengths up to 108” (2743mm). What is the longest Air Knife available? Are there other lengths available that aren’t shown in the catalogue or on your website?

The longest single piece Super Air Knife that we offer is 108″ (2743mm). If you require a longer length for your application, multiple Super Air Knives can be connected end-to-end with the Super Air Knife Coupling Bracket Kit. This will produce a laminar, uninterrupted flow of air across the entire length. If you require a specific length Super Air Knife, EXAIR will make it for you.
