Air atomising spray nozzles for moistening

In direct pressure nozzles the energy required to break up the fluid comes from the potential energy of the fluid itself.  As more energy is required to break up fluids into smaller droplets, pressure and flow rates need to be increased in order to form very fine sprays.  This increase in flow rate may not be desirable as it might result in too much fluid is being delivered, resulting in overwetting.

Air atomising nozzles overcome this problem by using compressed air to break up the lubricant into a very fine spray.  This means that even at very low flow rates and fluid pressures very fine sprays can be achieved.  Perhaps just as importantly the consistency of the spray can be controlled more easily with air atomisers because the air pressure can be varried as well as liquid pressure.

In the SAM series of air atomising nozzles the level of control over spray properties is taken a level further.  This range of nozzles has two separate air feeds as well as the liquid feed.  One air feed controls the level of atomisation and the other is used to shape the spray pattern.  Each feed is independent so absolute control over pattern and consistency can be achieved.  For very delicate or precise moistening applications this range of nozzles might be considered.

Air atomising nozzles can be used to produce hollow cone, full cone and flat fan patterns for moistening applications.  So they can be used to moisten product moving on a conveyor (use flat fans) or stationary targets (full cones).
