Ron Sweet, manager of operations and sales for Polymag Tek, says that non-contact cleaners are traditionally vacuum-type systems. These cleaners need to overcome limitations due to both static effects and a boundary layer of air that can form and travel along with the moving substrate. “These two conditions can trap particles of contamination and not allow them to be removed without direct contact,” he says.
