Grant Bottom Baffle Pair Mpbs12X Multipass 50/70

Grant Bottom Baffle Pair Mpbs12X Multipass 50/70

The Grant Bottom Baffle Pair MPBS12X is a genuine OEM replacement set designed for Grant Multipass 50/70 oil-fired boilers. These precision-engineered baffles are installed in the lower section of the heat exchanger to optimise heat transfer and improve boiler efficiency by slowing down flue gas movement, allowing maximum heat extraction.

Manufactured from high-grade, heat-resistant steel, the MPBS12X baffle pair ensures consistent combustion efficiency, reduced fuel consumption, and lower emissions. Replacing worn or corroded baffles helps maintain your boiler’s rated output and prolongs the lifespan of the heat exchanger.
