Boiler Dirt Filter Separator | Underfloor Heating Pre-Filter
Boiler Dirt Filter Separator | Underfloor Heating Pre-Filter
PRIMED Boiler Dirt Filter Separator with Built-In On/Off Handle
Keep your heating system running at peak efficiency with this industrial-grade Boiler Dirt Filter Separator. Designed for underfloor heating systems, boilers, and HVAC equipment, this pre-filter traps rust, scale, and sediment before they can circulate through your pipework — protecting your investment and extending the service life of your entire heating system. Made in Mainland China.
How It Works
- Radial Separation Mesh Screen: Forces water through a precision stainless steel mesh that intercepts impurities, causing them to settle into the storage chamber below.
- Removable Magnet Ring: Magnetically attracts rust particles and ferrous debris, binding them to the inner wall of the storage chamber and preventing them from re-entering the system.
- Large Internal Chamber: The generous internal volume slows water flow, allowing suspended particles to settle by gravity for thorough multi-stage capture.
- Built-In On/Off Handle: The convenient integrated drain handle lets you open the drain and flush the filter even while the heating system is still running — no need for full shutdowns.
- Scale, Rust & Sediment Removal: Single-stage filtration targeting the most common contaminants in closed-loop heating circuits.
Key Benefits
- Protects boilers, underfloor heating manifolds, and HVAC components from abrasive debris
- Improves overall system efficiency by maintaining clean water flow
- Industrial aesthetic blends seamlessly into plant rooms and utility spaces
- Easy maintenance — magnet ring and mesh screen are both removable for cleaning
- Threaded connection for straightforward installation on new or existing pipework

Frequently Asked Questions
Q: What size connections does this boiler dirt filter separator support?
A: This heating pre-filter is available in multiple threaded connection sizes including DN20 (¾"), DN25 (1"), and DN32 (1¼") in both male and female configurations. Some sizes come equipped with a ball valve for added flow control. Check your existing pipework thread size before ordering.
Q: Can I clean or service the boiler filter while the heating system is still running?
A: Yes. The built-in on/off handle allows you to open the drain valve and flush captured debris from the storage chamber without shutting down the entire heating system. For a full cleaning of the stainless steel mesh and removable magnet ring, a brief system pause is recommended.
Q: Is this filter suitable for drinking water applications?
A: No. This boiler dirt filter separator is designed exclusively for closed-loop heating systems such as underfloor heating and HVAC circuits. It is not rated or approved for potable (drinking) water use.
Q: What types of contaminants does this heating pre-filter remove?
A: The filter targets the most common contaminants found in heating circuits: rust particles, limescale flakes, and general sediment. The dual-action stainless steel mesh and removable magnet ring work together to capture both ferrous and non-ferrous debris.
