Beyond the initial goal of preventing fluid-contamination mishaps, the new AFSUs are made of composite materials, making them much lighter.
The AFSUs also are more efficient (3 ounces dispensed per stroke), compared to the HSU-1 (1.5 ounces per stroke) and the PON-6 (0.7 ounces per stroke).
AFSUs already are being delivered to units on the West Coast and will be available to all fleet units beginning this fall.
