Product catalog summary

Product Overview:
The SD1225PT ATEX Series is a DC Brushless Fan with electronic protection, available in wire lead type (WB) or terminal type (TB) ball bearing configurations. The fan measures 120 x 120 x 25 mm (4.7 x 1 inches) and features a plastic frame and impeller. It offers a maximum airflow of 120 CFM (3.4 m³/min).

Specifications:

Mechanical: Connection options include lead wires or terminal type. The fan weighs 152 g (0.336 lbs).
Electrical: Dielectric strength is rated at 500VAC/min with a maximum leakage of 0.5mA. Speed control options include PWM, SC, and SV, with signal output options of FG and RD.
Environmental: Operating temperature ranges from -20°C to +65°C, while storage temperature ranges from -20°C to +75°C at 65% RH. The life expectancy is L10 70,000 hours at 40°C.

Compliance:
The fan complies with several standards, including EN IEC 60079-0:2018, EN IEC 60079-0:2018/A11:2024, EN 60079-7:2015, EN IEC 60079-7:2015/A1:2018, and EN 60079-7:2015/A11:2024.
