Question
In an Accumulator behind the driver, how can airflow to the front of segments be provided?
Answer
For accumulators in the typical position behind the driver, we will not allow holes in the front Accumulator wall or top.
If airflow is needed to the front of the segments, the solution is to extend the container forward, creating another compartment solely for airflow.
The front compartment must meet the same requirements for Accumulator wall material.

If the extended side walls and floor are flush with the original container, then 10 mm hole patterns may be used for airflow.
Up to 25% of the total side wall and floor may be removed, and these may be concentrated in the front airflow compartment.
Leave a few mm between holes, it still has to be a sturdy wall.
Your design must meet EV.6.1.2, 100 mm x 6 mm round probe.

The location of internal holes is unregulated.
10 mm holes and 75% segment coverage continues to apply to all walls (internal or external) where holes are permitted.

Ducts may be freely attached to side, bottom, and rear openings without any need for review.

The front airflow compartment can technically be removable if the fasteners meet F.10.2.5.b, matching baseline weld strength, as with any other container wall.
