Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 °C +68 °F.
2) A typical sample applied with a supply voltage of 24 V, a distance of 100 mm 3.937 in from the front surface of the air flow outlet and a pressure of 0.25 MPa. (Measured on a sample left in the atmosphere at a relative humidity of 65 % RH or less for 24 hours or more.)
3) A typical sample applied with a supply voltage of 24 V, a distance of 300 mm 11.811 in from the front surface of the air flow outlet and a pressure of 0.25 MPa.
4) Dry clean air is air that has been processed through an air dryer (freezing point around -20 °C -4 °F) and an air filter (mesh size around 0.01 μm 0.0004 mil).
5) Discharge halts when lights up.
