Full-Flow Air Knife
This low cost choice provides a curtain of air for Blowoff, Cleaning, Drying and Cooling.
The Full-Flow Air Knife borrows engineering elements from our original Standard Air Knife with the added benefit of an airflow across its entire length. They also provides the smallest footprint of our Air Knife line to fit in cramped machine spaces.
These are a low cost choice and are available from stock in 3" to 36" lengths. The Full-Flow Air Knife is available in aluminum or Type 303 stainless steel. Custom sizes and materials are also available.

How the Full-Flow Air Knife Works?
Compressed air flows through the inlet (1) into a plenum chamber. It is then throttled through a thin nozzle (2) extending the length of the Full-Flow Air Knife. This primary airstream adheres to the Coanda profile (3), which turns it 90° and directs the flow down the face of the unit. The primary stream immediately beings to entrain surrounding air (4), for an amplifiecation ration of 30:1 at 6" (152mm) away.
OSHA MAXIMUM ALLOWABLE NOISE EXPOSURE
High noise levels are a common problem for many plants. Compressed air noise often exceeds OSHA (Occupational Safety and Health Administration) noise level exposure requirements, resulting in hearing loss to those working in close proximity. The sound level of the Super Air Knife is quiet at 69 dBA, even at high pressures of 80 PSIG (5.5 BAR). Using the Super Air Knife, it is possible to obtain hard-hitting force without the high noise.
