5.3 Installing the compressed air maintenance unit and compressor (optional)
To ensure the Mini Spray Dryer B-290 achieves an optimal atomization performance, the supply of
compressed air with a pressure of 5–8 bar is necessary. The compressed air must be dried and free of
impurities (contamination of the product through impure air). If this is not guaranteed, we recommend
the use of a WILKERSON maintenance unit.
Notice
Risk of instrument damage by internal overpressure.
• External supply pressure must meet the system specifications
• Exchange clogged or defective filters immediately
• Dispose of clogged or defective filter immediately

compressor with an output of 5– 8 bar as require.
