Airbrush 0.7mm Nozzle for GHAC-Swallowtail

The widest opening in the range for this machine

0.7 mm is a great deal from the point of view of a modeling airbrush. A diameter like that is not bought for shading or for camouflages with soft transitions, but for tasks where flow is what matters: applying a base coat to a large-format kit, thick protective varnish, dense textured compounds and finishes with a coarse pigment, which will reliably clog a thinner opening. The work goes quickly and an area can be closed before the edges set.

How to handle it

A larger opening calls for different settings from a fine nozzle. Thin the paint less, otherwise it runs, and rather lower the pressure; with a wide diameter it is possible to work even below one bar, which limits the flight of dry particles. Keep a greater distance from the surface than for fine work, because the cone is wider and a deposit quickly forms when you come close. It is recommended to make a test on a piece of cardboard before you set about a model. The difference from a fine nozzle is felt on the very first stroke.

The assembly and maintenance

A needle and an air cap of the same diameter belong with the nozzle; the brand carries them as separate items and a set that joins them together exists as well. After spraying, blow the nozzle through and run a brush through it, because dense material stiffens in it faster than thinned paint and the residue is then far harder to remove. Never put a metal tool into the opening, as the edge is easily damaged and it is a functional surface. Anyone who works with this diameter regularly will appreciate that it manages even paints which would otherwise have to be strained through a sieve before application.
