The passive discharge brushes are made of filaments that are very soft, while being extremely durable. Thus, there are no chances of scratches on the web even if brush fibres are in contact with the web. These are non-powered and perform more efficiently when the electrostatic charge on the web is high. Being passive static discharge elements that require no power, and are suitable for mounting in explosive environments. A Valstat® static discharge brush, positioned very close or nearly touching the charged web will minimise the electrostatic charge from the substrate and send it to ground. Valstat® passive discharge brushes can be combined with Valstat active static eliminating bars to provide a potent static elimination tool for virtually any web-fed application.
