Static charge can cause a number of problems across a range of industries:
- Dust clinging to a product, or product clinging to itself, rollers, etc.
- Tearing, jamming, or curling
- Feeding of sheets in printers, slitters, or cutters
- Nuisance shocks to operators handling statically charged materials
- Poor print quality (voids, misalignments, etc.) and even shorted printer/print head life
EXAIR Static Eliminators have been a popular, easy, and efficient solution for all of these and more, for decades. Really, the first thing we’re going to consider when specifying the right Static Eliminator is the size and shape of the ionized airflow that’s going to be needed. For pipe, hose, tube, wire, cable, extruded or molded continuous strands…anything that needs static elimination on all sides, really…EXAIR Super Ion Air Wipes are certainly worth a look.
Super Ion Air Wipes generate a uniform 360° ionized airflow to eliminate static on the surface of the above-mentioned materials. They come in two sizes: one with a 2″ inside diameter, and one with a 4″ inside diameter. The split clamp design means you don’t have to ‘thread’ the material through…you simply undo the latch on one side and fit it back around the material or part. Some of the more popular and successful applications include:
- Removing static charge from a 1.75″ diameter continuous feed of tubing on a pultrusion line that has axial slits cut in it. The slitting created an INCREDIBLE amount of static charge, continuously as the tubing moved through the process, causing shavings to statically cling to the surface. This caused false rejects in the inspection process, which were eliminated by the use of a 4″ Super Ion Air Wipe.
- A PVC pipe manufacturer encountered issues with the quality of text being applied on the outside wall of the pipe by an ink jet printer. On larger pipes, where the printing was applied on one side of the pipe only, they used Ion Air Jets to remove static from the immediate area of the printing. For their smaller pipes (1-1/2″ and smaller), they use 2″ Super Ion Air Wipes to remove the static from the entire perimetry of the pipe. Print quality ceased to be a problem.
- A wire manufacturer uses an encoder to measure & calculate wire lengths, so they’d know how much wire was going onto a spindle. The encoder wheel’s fabric coating and the wire’s nylon coating caused a static charge high enough to generate enough voltage to damage the encoder – they actually saw SPARKS coming off the wheel. A 2″ Super Ion Air Wipe removed the static from the entire area around the encoder.
- A bottled water plant applied tamper-proof seals to the top of the bottles once they were filled & capped. In addition to putting consumers at ease that their drink had not been tampered with, it also kept the top of the bottle (which most people’s lips touch) clean & germ-free. Static charge on the seal material caused improper application, sometimes not even covering the whole cap.
They’re also incredibly quiet (77dBA for the 2″; 81dBA for the 4″) and provide low-cost operation, consuming just 29.5 SCFM (2″) & 50.2 SCFM (4″) @80psig, considering they can eliminate a 5kV charge in one fifth of a second. Oh…they’re also in stock, available for same day shipment, and if you order before March 31st, we’ll even throw in a FREE AC Sensor with any Static Eliminator Product purchase.
So – what’s “super” about our Super Ion Air Wipes? I think the better question is, what’s NOT? If you have problems with static charge, EXAIR has solutions. Give me a call.
