KA2072HA1 KAKU high waterproof axial fan

Description

The KAKU KA2072HA1 is a high-performance 115 V industrial AC axial fan with dimensions of 208 x 208 x 72 mm, purpose-built to deliver elite-level thermal cooling in high-resistance airflow paths. This unit features a heavy-duty single-phase motor capable of sustaining an 85 W power input (at 50 Hz) or up to 115 W (at 60 Hz) to drive its specialized high-velocity impeller at speeds of 2900 RPM or 3400 RPM respectively. Engineered specifically for large-scale air displacement in electrical cabinets and heat exchangers, it utilizes a 72 mm deep metal alloy housing to provide balanced pressure and airflow for mission-critical hardware. The mechanical design relies on precision maintenance-free ball bearings and a black-painted frame to ensure reliable continuous operation across an ambient temperature range of -20 °C to 85 °C. Featuring a robust 2-wire electrical interface and an IP55 protection rating, this fan is a critical component for industrial automation, frequency converter cooling, and outdoor telecommunications cabinets where long-term durability and moisture resistance are mandatory.
