Centrifugal Square Inline Duct Fans
Greenheck's model SQ and BSQ centrifugal inline fans feature a unique combination of installation
flexibility, rugged construction, ease of service, high efficiency, and
low sound levels. These compact inline fans are the ideal selection for
indoor clean air applications including intake, exhaust, return, or make-
up air systems where space is a prime consideration. The need for
costly square-to-round transition pieces are eliminated
reducing installation costs. The square housing design,
compact size, and straight-thru airflow also give the
system designer the flexibility to mount SQ and BSQ fans
in any configuration - horizontal, vertical, or at any angle.
