EFD 900 Operating Manual page 13

If you use low to medium viscosity fluids, the white
SmoothFlow ™ piston has several advantages.
First, vacuum adjustment is much less sensitive.
Second, the piston prevents fumes from the fluid
being exhausted into the work environment. Third,
the piston prevents fluid backflow into the dis-
penser if the barrel is inadvertently turned upside
down. Fourth, using the piston makes it easy and
safe to change tips without dripping.
Note: If you use watery-thin fluids such as solvents,
cyanoacrylates and anaerobics, specify the ULTRA
System ™ with the blue LV Barrier
