The 1700 is a successor to the venerable Rosco 1500.  It can produce different effects from thick fog to light haze.

features:
o  variable fog output
o  continuous fog, no interruptions during re-heat cycle
o  3-liters/hour at full output
o  wired remote with timer
o  low-power draw - 1190 watts
o  choice of fog fluids for heavy or hazy effects

fog fluids:
We stock three choices of fog fluid for the 1700:

Rosco Clear - standard, thick fog, no scent added
Rosco Light - suitable for haze and wisp effects
Rosco Stage & Studio - faster dissipation

Read the MANUAL.

Use ONLY Rosco fog fluids.

The 1700 is designed for continuous use over an 8-hour day, but to protect components, it is wise to turn off the machine when it is not in use.

Before each operating period, check to see that the machine is clean and free of foreign objects.

Ensure that the machine is adequately ventilated.

Be aware of hot surfaces.

Use the minimum amount of smoke required to achieve the desired effect.

The smoke should be blown into an open space and should not be directed at people or objects. Never blow smoke on hot surfaces, into glowing heating elements or into open flames. The normally non-flammable and non-toxic smoke could react on very hot surfaces and be burnt or decomposed.

After long use, or if the machine is not properly set, some liquid droplets or wet area may appear in front of the machine’s outlet. This liquid should be wiped up to prevent a condition where someone might slip and fall.

Do not operate the machine in a tightly confined space where the ambient temperature might exceed 135° F (57° C). A continuous flow of air is required to maintain temperature within the machine housing.

The smoke should never mask emergency exits, safety signs, staircases or other safety constructions.
