D6F-W01A1

D6F-W04A1

Note: 1. Air velocity. D6F-W is optimally adjusted for air velocity de-

tection, derived from mass air-flow measurement according

to our in-house test method using a wind tunnel

φ 48 mm as

shown in Fig. 1.

2. Measurement condition: Power supply voltage 12

±0.1 VDC,

ambient temperature 25

±5°C. and dry air.

D6F-W10A1

Note: 1. Air velocity. D6F-W is optimally adjusted for air velocity de-

tection, derived from mass air-flow measurement according

to our in-house test method using a wind tunnel

φ 155 mm

as shown in Fig. 2.

2. Measurement condition: Power supply voltage 12

±0.1 VDC,

ambient temperature 25

±5 °C. and dry air.
