I work in an outdoor theater where we use fog in several scenes. We have a mountain that uses two fog machines the fire into one system. The problem is the system is about 8-10 years old and we have increased our fog output without changing the system to compensate for the increased volume. I'm basically looking for ideas on fans and delivery methods. The current setup is 2 Antari Z3000-II which are both tremendous machines. These fire fog into a "fog box" which is just a transformed road case. This is then connected to four slide valves that run for different setups.
