INTRODUCTION
Congratulations on your purchase of the Rosco V-Hazer. Designed to meet the varied demands of proj-
ects ranging from concert tours, theatrical productions and theme parks to feature films, television
broadcasts, and photo shoots, the V-Hazer offers the perfect balance of performance, reliability & afford-
ability, and delivers smooth even haze with just the right hang time.
To ensure efficient and safe operation, please take a few moments to read this manual completely.
The Rosco V-Hazer is a thermal aerosol generator designed for continuous, variable haze output. This
machine is one part of a system, the other component being Rosco V-Hazer Fluid. All Rosco Fog and
Haze Fluids are unique, water-based formulations that contain no petroleum distillates and are safe
when used according to instructions. The operating temperature, pump pressure, and output nozzle of
the V-Hazer have been specifically designed and engineered together to maximize the aerosolization of
the Rosco V-Hazer Fluid.
Do not use any fluids in the V-Hazer other than genuine Rosco V-Hazer Fluid, as they have not been tested for
optimal performance and safety considerations. Doing so may damage the machine and will void the warranty.
The Rosco V-Hazer has been tested for use in professional theatrical productions and is included un-
der the Equipment-Based Guidelines of the Equity-League Pension and Health Trust Funds. The Rosco
V-Hazer is also compliant with the Alliance of Motion Picture and Television Producers Safety Bulletin #10.
Note: The terms “fog,” “haze” and “smoke” are used interchangeably throughout this manual. Rosco Fog
Equipment does not produce actual smoke, only a mist or aerosol.
FOG FLUID HEALTH CAUTION: VAPOR FROM THIS FLUID, LIKE ANY OTHER COMMON MATERIAL IN A
VAPORIZED STATE, MAY BE IRRITATING TO OR CAUSE ALLERGIC SYMPTOMS IN SOME PERSONS WITH
ALLERGENIC SENSITIVITY. DO NOT EXPOSE AT CLOSE RANGE TO KNOWN ASTHMATICS.
