Spirotech has announced the introduction of its SpiroTrap Heat Pump Filter (HPF), a new dirt filter designed to protect heat pumps against both magnetic and non-magnetic contamination.
The company says the SpiroTrap HPF is designed to protect heat pump systems featuring a design based on extensive field research in residential installations across several European countries, combined with Spirotech’s many years of expertise in water quality and dirt separation.
The core consists of three components:
Fine mesh filter – captures high-risk particles larger than 160 µm.
Powerful magnet – removes magnetic dirt particles
Patented Spirotube – slows the flow and directs particles toward the collection zone.
The company says that thanks to this combination, the filter is relieved of excess load, the flow remains optimal, and the system is protected over the long term — without a bypass, ensuring that no particle can escape filtration.
According to the company, the SpiroTrap HPF has been developed with the heat pump’s maintenance interval in mind (on average every two years). It says the integrated backflush function makes filter cleaning simple: with a single turn, the flow direction is reversed, and accumulated dirt is discharged via the drain valve — no disassembly, tools, or spillage required.
The SpiroTrap HPF is available in multiple connection sizes (22 mm, 28 mm, ¾”, 1” and 1¼”) and suitable for systems up to 2 m³/h. Spirotech provides a 10-year warranty.
The SpiroTrap HPF will be available from April 2026.
