Is there a quick way to clear pyro smoke?

[ukdeveloper]

Were using these:

 

 

in a relatively small theatre. The theatre does have air con but does not have extraction for smoke. Does anyone have experience of these particular pyro and how much smoke each individual pod gives off?

 

Or more importantly anyone have any idea of a quick way to clear smoke? would a couple of fans placed up in the lighting truss to blow smoke into the wings be good enough?

 

The issus we have is this effect is going to be used for an OPENING sequence for a show and we don't want to choke audience members with pyro smoke.

Cascades/waterfalls do produce quite a lot of smoke, so I'd say that you will be stuck with it.

 

Blowing it around is going to do pretty much nothing for you due to the nature of the smoke - it will remain airborne until the particles have a chance to settles, and fanning them about will just delay that. And in a small space that just becomes harder to manage.

 

If you use them, it will just be something you'll have to live with.

You need to look at clearing the smoke out of the venue, not just into the wings.

 

Do you have a high ceiling to fit exhaust ducting into if you have a floor above the stage ? The exhaust ducting has inlet vents in the side so it can fit flush against the roof.

 

Is it possible to have exhaust fans in side windows on one wall of the stage and exhaust fans on the side of the stage pushing the smoke towards the exhaust fans on the wall, or not as effective, blowing fans on the opposite side of the stage pushing the smoke towards the exhaust fans. The pushing fans may push some smoke into the venue.

 

I have taken glass windows out of stage side windows and fitted exhaust fans, to remove smoke during Eurobeat.

 

Have you disabled smoke alarms ?

It depends how many you are going to be using, and the space you are using them in. Waterfalls and cascades do give off quite a bit, and the smoke tends to linger for quite a long time...but in terms of volume of smoke, they are definitely not the worst. But depending on your venue size, you might be left with a light haze or post-apocalyptic smog. If you do not have sufficient ventilation, the only thing I could suggest would be to keep intro pyro to a minimum and save it for a grand finale.

You either spend the money on vent fans and ducting trying to keep the airflow outward but not fast enough to flutter the drapes, OR you spend the money on electrostatic precipitators that really will pull the fog from the air.
