K2E250-AH38-16 ebmpapst SK3244.110 Rittal 115V Filter Fan

Description

The ebmpapst K2E250-AH38-16 AC Diagonal Flow Fan operates at 115 V AC and is the main cooling component in the Rittal SK 3244.110 Filter Fan Unit, measuring approximately 250 mm in size. The fan is a single-phase (1~) unit with a ball bearing system, providing a high unimpeded airflow of 700 m³/h at 50 Hz and 770 m³/h at 60 Hz. Its key electrical specifications include a rated power of 100 W (50 Hz) and 145 W (60 Hz), and a current draw of 0.9 A (50 Hz) and 1.25 A (60 Hz). With an IP44 protection rating and a wide operating temperature range from −30 °C to 55 °C, it is ideal for industrial enclosure climate control and cooling of electronic equipment to maintain system stability.
