Hydraulic characteristics
Flow Capacity
The fluid velocity at connections for DISCALDIRT 546 and NA546 series air and dirt separators
is recommended to not exceed 10.0 f/s. Above this speed, heavy internal turbulence and
noise can occur and air and dirt elimination efficiency begins to fall measurably. Optimal air
and dirt separation performance occurs at fluid velocities of 4.0 f/s or less. See the flow
capacity chart.
