Similarly, if the blender is set to deliver 100% concentration and AIR source
pressure is reduced or lost, the unit may not alarm because it will continue to
deliver the selected 100% concentration.
If the blender is left connected to source gases but is not being used (i.e., no
output flow or bleed flow) the unit will not alarm if a 20 ±2 PSI or greater
pressure differential develops. If the blender is not in use, an alarm under these
conditions will be an unnecessary distraction or nuisance.
Outlet Ports
On the Low Flow MicroBlender, two outlet ports are located on the right and
left sides of the MicroBlender and allow low ranges from 0-30 LPM with bleed
and 3 - 30 LPM without bleed respectively. On the High Flow MicroBlender, the
primary outlet port is located on the bottom of the MicroBlender, and the
auxiliary outlet is located on the right side of the MicroBlender, allowing ranges
from 15 to 120 LPM without bleed and 2 to 90 LPM with bleed respectively.
Bleed Outlet
For the Low Flow MicroBlender, when a connection is made to the right side
outlet port, for example, when a flow meter is attached, a bleed flow of 2.5-
3.5 LPM is achieved. For the High Flow MicroBlender, when a connection is
made to the right side outlet port, a bleed flow of 10-12 LPM is achieved. For
both Blenders, the bleed flow exits the unit through a muffler port located on
the bottom of the MicroBlender.
