I find that the pressure on compressed air drops with a subsequent
temperature rise during meetings resulting in a normalised pressure,
greater quantity and hotter temperature of air.

Barbara,
Besides moisture, oil, ESD and noise, make sure you check with your
jurisdiction's limits on allowed maximum compressed air pressure for air
guns held by individuals.

Hi Barbara,
Using an ESD ionizer gun which is provided with clean (moisture free and
oil free) compressed air or nitrogen would be ok. I install the
ionizing guns with a large silica gel moisture trap right next to them
to guarantee the dryness.
Compressed air lines are notorius for containing all sorts of
contaminants and air blow off guns usually require safety precautions as
they may exceed noise limits as well, besides the ESD hazard.
Hope this helps,
Phil

Don't! (ESD) Better to wash them off with DI water plus detergent
followed by copious DI water rinses and dry. In any case, most
compressed air is too dirty for using on electronic assemblies.
