Ducting

If ducting is required the LSG Mark II output requires a 10" flexible duct, and can be ducted up to 50 feet
horizontally. The ducting is available insulated or non-insulated and can be purchased though an industrial supply
company or from Ultratec Special Effects (Part # CLF ).
The LSG Mark II may also be ducted vertically up to 20 feet to produce a waterfall or cascade effect. When
ducting fog vertically, the remaining fog in the duct must not be allowed to backflow into the LSG Mark II. When
this happens repeatedly the glycol in the fog may condensate on the inside of the G300, damaging the electronic
components. See further in this manual for suggested solutions and ducting examples.
TECH TIP: If dividing the output to more than one location while ducting, make sure the sum of all cross sectional
areas of the final duct sizes are equivalent or greater than the cross sectional area of the LSG Mark II 10" outlet.
Doing this will prevent any backpressure being created by the LSG Mark II.
The formula for cross sectional area: 0.78539 x (diameter squared)
Example:
The LSG Mark II outlet has a diameter of 10": 0.78539 x 100= 78.5" square inches is the area of the LSG Mark II
outlet.
If you require 3 locations to duct the effect to, then the cross sectional area of the 3 ducts must be greater than
12
