Filter fans save time and money

Haewa Corp. has expanded its filter fan line with the addition of five standard 24VDC sizes from 4 in. by 4 in. to 13 in. by 13 in. The fans save time and money because of their integrated gaskets, snap-in no-screws mounting and easy front grid exchange of filters. And improved airflow from 33 cfm to 605 cfm and low-profile esthetic appearances enhance performance.
