The Titan 1800PRO is our most powerful fog machine to date! It is loaded with all the features professionals crave. The Over-sized Heater Core increases run times, Quick Ready Fog Technology (QRFT) has you ready to fog in less than 10 seconds after full cycle, and Advanced Low Fluid Sensing shuts down the machine when you run out of fluid to protect the heater core. The 1800PRO also boasts a whopping 1800W heater core to produce over 40,000 CFM. Instant Stop Technology (IST) pulls fluid out of core to reduce spitting and give precise fog output.
