ATEX DC FAN series

Product catalog summary

Product Overview: The SD1238SPT ATEX Series is a DC brushless fan with electronic protection, designed for industrial applications. It features a plastic frame and impeller, with dimensions of 120 x 120 x 38 mm (4.7 x 1.5 inches). The fan offers a maximum airflow of 285 CFM (8.1 m³/min).

Specifications: The fan is available in wire lead or terminal type connections, with a weight of 315 g (0.69 lbs). It has a dielectric strength of 500VAC/min with a maximum leakage of 0.5mA. Speed control options include PWM, SC, and SV, while signal output options include FG and RD.

Environmental Conditions: The operating temperature range is -20°C to +65°C, and the storage temperature range is -20°C to +75°C at 65% RH. The fan has a life expectancy of 70,000 hours at 40°C.

Compliance: The product complies with standards 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.

Performance Data: The fan models vary by voltage, power, current, speed, airflow, static pressure, and noise level. For example, the SD1238SPT-48EH model operates at 48 VDC with a power consumption of 84.96 watts, achieving a speed of 6,000 RPM and a maximum airflow of 285 CFM at a noise level of 64 dB(A).

Model Variants: The document lists several model variants with different specifications, including SD1238SPT-12SH, SD1238SPT-12HHH, SD1238SPT-24SHH, SD1238SPT-24SH, SD1238SPT-24HHH, SD1238SPT-48EH, SD1238SPT-48SHH, and SD1238SPT-48HHH, each with specific voltage ranges, power ratings, and performance metrics.
