The tribo method of application is ideal for coating the more complex shaped objects, which are difficult to spray with the corona principle of electrostatics. Powder sprayed by the TRV 117 penetrates recesses due to the lack of electrostatic ionization and overcomes the Faraday cage effect. This sprayer has been designed with the latest design features to create a reliable and economic spray gun. It has been designed with three pneumatic controls which regulate the following: injection air adjusts the powder flow (11 kg/h max. recommended); dilution air enables a constant flow of powder at low flow rates and additional air control increases the friction charge with out increasing the powder flow.
