How many lasers can you hook up to one exhaust fan?

[Larry Alles]

So, how many lasers can be hooked up to an outside exhaust. We have two hooked up to one exhaust right now with shutoffs for each one. Can we hook up three lasers with shutoffs without any trouble? All lasers are Epilog. One is a mini 24TT, one is a Fusion 2 and the other is a Legend 24X36.

I have my Trotec and two fibers hooked up to one HF exhaust fan with blast gates on each one. Each gate will leak a bit so I'm sure there is some limit before you start seeing it become innefective, but I wouldn't worry about that with three.

Complicated question depends on your blower and your exhaust duct. Not trying to be smart here but let's say you had two blowers each with a 6" exhaust port. Nothing says those two blowers couldn't go out a single 10" or 12" exhaust port if you direct the air properly.
