Hoffman brand filter fans

More than 175 models of Hoffman brand filter fans are available to suit a broad range of electrical and electronics cooling applications, including industrial drives; automotive assembly; materials handling equipment; food and beverage process controls; and wind-energy systems. The filter fans are engineered with rugged UV-resistant plastic and foam-in-place gaskets, providing a tight seal with the cabinet. Models provide airflow from 28 to 970 m³/h to cool a wide range of heat loads. A click-fit design facilitates fast and easy installation, and a snap-open grille allows simple filter replacement.

Filter fan models available include side-wall and roof-mount options with AC and DC power input options. Reverse-flow models push/pull air through higher static pressure systems and compact, shallow design models allow installation into tight spaces. IP55 filter fans deliver dual protection against water infiltration through a corrosion-resistant metal grille positioned in front of a high-density Z-filter. The minuscule louvres in the metal grille open in the opposite direction of the louvres in the fan’s plastic grille, creating an extra physical path in front of the Z-filter that protects against water ingress. An optional stainless steel shroud is available for washdown protection.

Features include wide selection of AC and DC power inputs with an optional thermostat to save energy and extend service life, shallow depth models for small spaces and reversible airflow models available - no field modification needed.
