The question is usually put the wrong way round: how much airflow does a rail car need? The car needs none. The chamber does.
The air capacity large chambers require is derived from the chamber volume the part imposes, not from the surface area of the part itself. Capacity therefore rises as the chamber lengthens even when the part stays the same.
Reading the published range correctly
Delivered air capacity in this family runs from 18,000 to 190,000 m³/h per supply or extraction set. That last phrase is the key: the figure is per set, and large-structure chambers are delivered with two.
That is why the published figure for this class is written 190,000 + 190,000 m³/h rather than as a single number.
| Class | Published air capacity |
|---|---|
| Family minimum | 18,000 m³/h |
| Trucks and buses | up to 72,000 + 72,000 m³/h |
| Aerospace, marine and rail structures | up to 190,000 + 190,000 m³/h |
| Accompanying heat output | 200,000 – 600,000 kcal/h |
Capacity pulls other items with it
Higher airflow means a larger air handling system, wider ducting, and a stack whose height and position follow the size and the site. It also means higher filter consumption, because the mass of air passing through is greater.
Published electrical power in this family runs from 11 to 50 kW depending on size and configuration, and large chambers sit at the upper end of that range.
Frequently asked questions
Can a chamber run on a single set?
The range is published per supply or extraction set, and the number of sets follows chamber volume and the approved configuration. That decision is taken with the other configuration items before manufacture.
What filtration accompanies these capacities?
In large-structure chambers, up to three-stage bag and high-efficiency filtration at 98% or better.
What electrical supply is required?
380 V three-phase at 50 or 60 Hz — the same value across all documented models.
