- External removable magnet
Nickel-plated brass body
Made of nickel-plated brass, combining the mechanical strength and durability of brass with the corrosion protection of nickel plating.
This treatment ensures a smooth surface, high resistance to wear and corrosion, even in harsh conditions.
Ideal for heating systems, it guarantees reliable performance and long-lasting durability.
Ultra-compact magnetic water filter designed to fit most boilers on the market
With a height of just 105 mm and a 90° elbow connection, it offers maximum installation flexibility, even in tight spaces.
Ideal for protecting heating systems without compromising practicality and accessibility.
Neodymium magnet
The magnet inside the water filter captures ferrous particles in the heating fluid, preventing corrosion and damage to components.
Made of neodymium, it provides strong magnetic force for effective metal removal.
It is easily removable by unscrewing the external cap, simplifying maintenance and cleaning.
Stainless steel AISI 304 water filter mesh
The 500-micron filter mesh in magnetic water filters captures large particles, preventing damage and blockages.
Made of AISI 304 stainless steel, it ensures corrosion resistance and durability. The 500-micron weave balances filtration efficiency and optimal flow, avoiding pressure drops and excessive energy consumption in the recirculation process..
Perfectly paired with Sirio anti-scale
For complete protection of the boiler heat exchanger, pairing the Astro magnetic water filter with the Sirio series is recommended.
Sirio treats domestic cold water, preventing limescale and scaling.
Combined installation ensures maximum efficiency, extends the boiler’s lifespan, and enhances the performance of the entire heating and hot water system.
High flow rate with low pressure drop
For effective water filtration in heat pumps, it is essential to maintain low pressure drop while still ensuring excellent filtration and dirt separation.
