To what degree do you think it is possible to control where haze goes using fans? Most of the time, the haze rises pretty quickly and builds up at ceiling level down to where the thermal layer exists from the HVAC. Since there is no fly space, it drifts out over the audience.
Two of the HVAC returns are at the rear of the room at ceiling level and the two HVAC unit's returns are distributed in numerous floor grates throughout the seating area. There are no returns on the stage or behind the stage, so all airflow is toward the audience
The producers complain that the haze drifts out toward the audience rather than "staying" in the stage area. Ambient temp and humidity seem to have a large effect on the amount of haze for a particular DMX setting (lemaitre radiance), but still the drift is always toward the audience.
Other than changing the HVAC returns or doing something to provide return airflow on the stage, is there anything else we could try?
