6. Waste removal
MIETZSCH-made fans are long-lived products. Consequently, waste removal is a problem occurring not earlier than
many years after starting.
According to present legal prescriptions, the single components are not regarded as hazardous waste.
Metal components (base, motor, screws etc.) are scrapped as usual.
Plastic components have to be cleaned and can then be treated as normal waste.
Residual materials and deposits in the fan have to be removed by the user in consideration of conditions of environment
control.
