Wagner Grounded Powder Hose 12mmWhen powder paints are carried by airflow, electrostatic charging occurs. Normally this charge is taken away by earthing. With plastic powder hoses, this is not possible. To alleviate this situation the new powder hose has an electrically conductive carbon strip, which dissipates the frictional charge. The grounded powder hose is earthed through an earthing contact on the outside or the inside e. g. on the powder injector.
