Overview

The Hammond Manufacturing HB4500A is a 19-inch, 4U rack-mount blower designed for industrial cooling applications requiring high airflow and reliable operation. This unit delivers a free flow air delivery of 405 to 465 CFM, making it suitable for dissipating heat in densely packed electronic enclosures, server racks, or industrial control panels. The HB4500A operates on 115VAC at 50/60Hz with a running current of 2.5A, ensuring compatibility with standard power systems. Its motor is UL recognized and CSA certified, equipped with ball bearings cooled by incoming air for extended service life. Constructed from heavy steel with a stainless steel grille, the unit withstands operating ambient temperatures from -20°F to +250°F. Internal neoprene isolation mounts minimize vibration transmission to the rack, while a permanent filter provides pressurized filtered air intake. Optional replacement filter packs (HB4UFILTER) are available for maintenance. The HB4500A includes a 6ft STJ 3-wire cord and is TAA and RoHS compliant. With a noise level of 76 dB, it balances performance with operational quietness. Dimensions: 19" width x 7.00" height (4U). Manufactured in North America.
