When larger areas need to be covered with an ionized air stream and the surfaces needing to be covered are not flat, then an array of Gen4 Ion Air Cannons can often be the solution. This is something that the automotive industry as well as many others have been using since before I have been a part of the EXAIR team. So just how does the Gen4 Ion Air Cannon achieve this?
At its core, the Gen4 IAC is designed around a 2″ Super Air Amplifier, and then we add ionization and a stand. The largest benefit to this is the ability of the Super Air Amplifier to entrain large volumes of free ambient air while using small amounts of compressed air. By entraining large volumes of free ambient air and then directing it down through the throat of the IAC and ionizing it upon exit of the barrel, we maximize the potential to eliminate static on the target surfaces and provide a good blowoff at the same time. To give a visualization of the performance, check out the video below.
When adding ionization to this airstream, complex shapes can easily have static elimination as they are being conveyed. Take an automotive body for example, as it travels down the assembly line, before paint or primer, they get blown off to ensure any debris from the facility is removed before they are coated. An array of Ion Air Cannons can be installed at a distance from the surface to fit multiple vehicle models and still target the entire surface needed.
By arranging the blow-offs to utilize the large volume of ambient air entrained and direct the airflow at an angle in which once it hits the surface, it expands in the direction needed to remove the debris it is easy to cover irregular shapes. The setup shown above will utilize 15.5 SCFM per IAC when operated at 80 psig and give a forceful blast to remove any debris on the surface; the total consumption would be 45.5 SCFM at 80 psig to remove all debris from the top surfaces of this vehicle body before it goes into the final paint area. A centrally located 4 port Gen4 Power Supply, model 7961, can simplify cabling and installation while powering all three Ion Air Cannons. To optimize compressed air usage, an Electronic Flow Control can easily be installed to shut the air off whenever a car is not present; adding something like this ionized blowoff station to existing equipment is easier.
