The new manual electrostatic spray guns EcoGun AS MAN DC/EC developed by Dürr allow to reduce overspray by 40%.
The German engineering company Dürr
has recently presented the EcoGun AS MAN DC/EC, its new range of manual electrostatic air spray guns that ensures 40% less paint consumption and thus a more efficient painting process. The new solution is available in two different versions: with direct or external charging.
The EcoGun AS MAN DC (direct charging) has an electrode on the spray gun needle which charges the paint and then applies it to a grounded component, while the EcoGun AS MAN EC (external charging) positively charges the paint particles by passing them through an electrostatic field; a negatively charged workpiece then attracts these paint particles.
“Electrostatics reduce paint consumption, because the attraction between the particles and the workpiece results in less overspray during the painting process. As a result, the EcoGun AS MAN DC/EC consumes up to 40% less paint than conventional air spray guns. Simultaneously, the electrostatic charge accelerates the painting process by creating a so-called wrap-around effect: the charged paint particles follow the electric field lines. As a result, it even reaches surfaces on the back of the workpiece,” has stated Tom Reiner, a product engineer from Dürr.
The new guns are equally suitable for applying solvent and water-based paints
and their ergonomic handles and low weight offer operators a comfortable painting process, even for extended periods. They are then ideal for applications where workpieces, such as tubes, rims, two-wheelers or train parts, need to be painted manually.
