low/high-pressure lock (???), pressure regulating lock (?)

A long shot maybe, but use of "tension" here is so strange that I have to look for something beyond the obvious (sic?).

I would be happier with the expression were it "sas (de) détension". Contrary to "tendre", in my experience, the verb "détendre" is habitually used in relation to air and gas pressures (you get a "détendeur" on your gas appliances, for instance), where it is a pressure regulator. So I wonder if your airlock is not in fact the point from which air is drawn out of a workshop say. This MIGHT be of use in a paint shop, as a means of keeping the workshop air pressure lower than that outside. This WOULD prevent atomized paint going everywhere, but would induce the risk of dust getting into the shop and spoiling the fresh paint.

On the contrary, if "tension" is used (unusually) simply as the opposite of "détension" used with the same meaning as "détendre", it could be the reverse, i.e. a high pressure airlock (not sure airlock is the right word though, in either case) into which air is pumped. Keeping the internal air pressure high would prevent dust getting in.

Then again, "sas (de) détension" could imply that the place has a pressure regulating function, like a "détendeur", in which case it would hardly matter whether you specified high or low pressure.

Of course air pressure and flowrate are, or can be, intimately related. It is, after all, the pressure difference induced by flowrate (and velocity) that makes planes fly. Well, engines help.
