The Alpha 900 is the lowest priced of all Rosco fog machines, but it has a large volume for such a small machine. Weighing less than 12 lb. (5 kg), the Alpha 900 delivers quite a punch for a machine with a 1000 watt heater.

The Alpha 900 is operated from a hand held remote attached to a 30 ft. (9 m) cord which has a simple ON/OFF switch.

The Model 900 is CE compliant and carries a limited 1 year warranty.

The Delta 3000, Delta Hazer, Model 1600, Alpha 900 and the PF-1000 have been tested for use in professional theatrical productions and are included under the Equipment-Based Guidelines of the Equity-League Pension and Health Trust Funds.
