Thank you so much!

:TBolt: I am a little confused with the thunderbolt blower types. All I know (and may not be correct) Is that the A1 blower is the quietest and has the 'Pulsey' sort of sound. I am not certain of any others? Could someone explain and possible find videos of sirens with different blowers so I can try...

Id say any mesh that can pass large amounts of air through it and can block small debris would be fine :TBolt:
