GFA models of GFS’ tube axial fans feature continuously welded
housing for an airtight seal. The propellers are non-sparking cast aluminum,
providing consistent air velocity at higher static pressures. The universal
motor plates allow for adjustable belt tensioning. The bearings are of premium
air-handling quality, self-aligning and have an L10 life of 40,000 hours. The
belt guard provides protection from the rotating pulley, per OSHA requirements.
