Spray nozzle prevents waste
The redesigned ViscoMist spray nozzle from Lechler (St. Charles, IL) incorporates features that reduce the chance for fluid to drip when the nozzle is not in use. The device’s new O-rings provide a better seal than before when the nozzle is shut off. In addition, the nozzle’s shut-off needle has been improved.
Lechler has slightly extended the ViscoMist nozzle’s liquid orifice upward to eliminate the bearding effect. The orifice is completely encircled by a pneumatic port that helps blow particles away from this area without interfering with the orifice’s ability to create the shape of the spray pattern.
One available model of the nozzle contains three ports for incoming air. One port controls the signal air and turns the nozzle on and off. Another port controls atomizing (i.e., droplet size), and the third controls the shape of the spray. Users can adjust either of the latter two parameters without affecting the other.
