The Grant Mag One Duo Magnetic Filter
helps prevent build-up of debris in pipework and provides long-term
protection to support the lifespan of a central heating system.
Featuring a direct filtration design, it offers improved overall
filtration levels compared to the Vortex Mag One. The Mag One Duo
maximises capture of debris, ensuring all the circulated water in a
system passes through the filter cartridge with excellent filtration
levels.

This installer-friendly universal filter is suitable for installation
with traditional boilers, including oil and gas boilers, as well as
renewable energy systems, such as an air source heat pump. The Grant Mag
One Duo Magnetic Filter provides system protection for heating systems
using a boiler up to 36kW in heating output or heat pump systems up to
10kW heating output (for larger systems, two Mag One Duo filters can be
fitted in a parallel circuit).
