HEA NOZZLES FOR LOW-MIST SPRAYING AT LOW PRESSURE
HEA stands for High Efficiency Airless, an innovative nozzle technology revolutionising airless spraying. HEA nozzles allow the pressure
of the spray device to be reduced right down and allow it to work in the low-pressure range (ideally at 80 - 140 bar). The nozzles can
be used with all TradeTip 3 nozzle holders and WAGNER devices.
Some paints may need to be diluted to achieve the best result possible. The experts at Wagner application technology have therefore
tested a wide range of materials for you. Their recommendations can be found in the Wagner Spray Guide at sprayguide.wagner-
group.com.
If edges are visible, slowly increase the
pressure.
Even spray pattern without spray edges.
Set the low pressure in the HEA range
and start.
