Grant Baffle Set – MPBS13

Genuine Baffle Set for Grant Multipass 70/90 Boilers

The Grant MPBS13 Baffle Set is a genuine OEM replacement designed for use in Grant Multipass 70/90 oil boilers. Baffles play a vital role in increasing boiler efficiency by slowing down the flow of flue gases, allowing more heat to transfer into the boiler’s heat exchanger. Over time, baffles can deteriorate due to high temperatures and soot build-up, reducing your boiler’s performance.

Replacing worn or damaged baffles with the MPBS13 set ensures optimal combustion efficiency, reduced fuel usage, and reliable heat output—all while maintaining compliance with manufacturer service requirements.
