If the fan isn’t capable of moving the air in the first place, that’s all kind of moot. 200cfm is barely a bathroom exhaust fan, which would be fine if all you had to worry about was steam.That’s not a measured airflow (mass flow) though Colin, it’s just a total volume measurement. Mass flow is measured in mass/time units, usually Kg/s.
Whats most important in this context is air velocity at the user face. This is measured in length/time units, like feet per second. To be most effective air velocity needs to be as even as possible across the entire face of the booth. This means no areas of the booth are not doing their job.
It is no good having a booth fan that can move huge amounts of air if it is only moving it from one spot. The rest of the booth will then have dead air areas and not collect contaminants. Unfortunately you can’t tell this without seeing one in operation and actually measuring it. I would say a higher quality unit is more likely to achieve this though.
Sorry Jim, didn’t see this until after I posted….I’ll stop nowThis thread, which I started, appears to be going round in circles. Some feel that the booth I have bought is not up to the job and expensive. That's their opinion. Reviews on the web and the experience of others disagree. Let's leave it there and beg to differ. When all's said and done it's my money and my choice.
