Tape casting machines airflow

All fans used on or near the tape casting machine should be explosion-proof if volatile, flammable solvents are being used in the process. On many of the laboratory-scale machines this problem is eliminated by the use of "house air" provided by a remote compressor. On these systems, the airflow through the machine is controlled by the use of flow meters and the cross-sectional geometry of the drying chamber itself. 

The basic principles of the tape casting process are included in most of these machines whether they are laboratory casters or production-scale models. The major components needed for tape casting include a solid, level casting surface, a drying chamber with a built-in means for controlling the airflow over the drying tape, an adjustable speed carrier drive control with a constant speed regulation mechanism, an air heater to control the temperature of the filtered feed air to the... 

Therefore, in our hypothetical tape casting situation, an airflow rate of 3.267 mVmin would be required as a minimum value for safe operation. This translates to 115.36 cubic feet/minute for those of us who still think in English units. Most machine manufacturers take these calculations into consideration when designing the minimum...
