EXAIR’s Full-Flow Air Knife is an effective way to clean, dry or cool parts, webs or conveyors. It utilizes the coanda effect to pull in large volumes of surrounding air, producing a high flow, high velocity curtain of air. The “Full-Flow” provides airflow across the entire length. A 12″ (305mm) Full-Flow Air Knife measures 12″ (305mm). It has the compressed air inlet(s) on the rear. Inlets are available on each end at a small additional charge but are not recommended when uniform airflow is required.
A Full-Flow Air Knife has a .002″ (0.05mm) gap setting. This gap is set with a shim positioned between the cap and the body of the Full-Flow Air Knife. Force and flow through the Full-Flow Air Knife may be easily increased by adding shims to open the gap. Kits include a shim set. Shim sets for aluminum Full-Flow Air Knives include a .001″ (0.03mm), .003″ (0.08mm) and .004″ (0.10mm) thick plastic shim. Shim sets for stainless steel Full-Flow Air Knives include (1) .002″ (0.05mm) thick stainless steel shim.
EXAIR’s EFC is an electronic flow control that dramatically reduces compressed air costs by turning off the compressed air when no part is present. This minimizes compressed air use for blow off, drying, cooling, conveying and static elimination operations. The EFC combines a photoelectric sensor with a timing control that limits compressed air use by turning it off when no part is present.
