[SML] Air Brakes/Casters

[Rick Clever]

Hello Stagecrafters,

I have finally had a chance to play with pneumatic caster mechanisms
and am starting to put together a system. I have noticed that in a lot
of the pictures I have seen the air tanks only have a regulator and no
filter. Is this standard? Should I have a filter inline to keep
moisture out of the lines or are these for such short term use,
moisture is not an issue?
