Pentair Technical Products Hoffman Brand Filter Fans Offer Broad Range of Capacities and Designs for Cooling Electronics

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 miniscule louvers in the metal grille open in the opposite direction of the louvers in the filter fan’s plastic grille, and creating the extra physical path in front of the Z-filter further protects against water ingress. An optional stainless steel shroud partners with the IP55 filter fan for maximum washdown protection.

“With more than 175 new models, there are multiple choices available for every application,” said Heidi Hung, Pentair Technical Products’ product manager. “To help customers select from versatile options—including airflow capacity, types of protection, power input options, size and more—free online selection software is available.” Hung adds, “All models feature robust UV-resistant plastic and tight seals to provide reliable, long-lasting operation.”
