What it is

The Buderus 73457 Sealing Fan is a sealing component supplied by Buderus for use on 800 series oil boilers. It seals the fan mounting face, helping to keep combustion air and flue gases contained at that joint. It is classified within oil boiler spares as an O-ring, washer or gasket item.

Signs this part needs replacing

  • Visible oil or combustion residue tracking around the fan mounting joint
  • A hardening, flattening or splitting of the old seal when inspected
  • Soot deposits or staining at the fan flange after servicing
  • Persistent combustion smell from the fan area during operation

Before you order

  • Confirm the boiler model and GC number against the fit list above
  • Inspect the existing seal for the correct profile and seating position before removal
  • Check the fan mounting face for distortion or corrosion that could prevent a clean seal
  • Work on oil boiler combustion components should be carried out by a competent heating engineer
