Questions about this item

Which Grainger part numbers does the BLW-001 blower wheel replace?

The BLW-001 replaces Grainger part numbers 1UNH7, 1UNH8, 1UNH9, 1YMJ6, 1YMJ7, 1YMJ8, 1YML7, 3KH80, 4Z714, 4Z715, 4Z716, 5PYN3, 5PYN4, 5PYN5, 5PYN6, 5PYN7, 5PYN8, 5PYN9, 5PYP0, 5PYP1 and 5PYP2.

How is the blower wheel installed on a Master Appliance heat gun, and what step is often missed?

Remove the retaining nut, slide the BLW-001 onto the motor shaft with the hub facing the housing, then re-tighten the nut; the step often missed is checking that the wheel spins freely before re-applying power.

When should the BLW-001 blower wheel be replaced?

Replace the wheel when the blades show cracks, chips or deformation, or when airflow drops noticeably on compatible HG-201A, HG-202A, HG-301A, HG-302A, HG-501A, HG-501A-D, HG-502A, HG-751A-C, HG-751B, HG-752A, VT-750C, VT-752C, VTS-750 or VTS-752 models.
