Product overview
Lubretec magnetic filters provide a continuous, non-intrusive solution to remove ferrous (iron and steel) particles from lubricants and other process fluids. Installed inline or in bypass, they capture metallic debris without restricting flow or creating pressure drop, protecting components and extending service intervals.

What are magnetic filters and how do they work?

• Lubretec magnetic filters use high-strength magnets to attract and retain ferrous particles from circulating fluids.
• They trap steel dust, iron filings and similar contaminants that contribute to wear, reduced efficiency and component failure.
• Suitable for lubricants, coolants, water, hydraulic and transmission fluids, and cutting oils.
• Offered in multiple models and configurations to suit inline or bypass installations and low- to high-flow systems.

Key advantages:

• No flow restriction, even when the unit is loaded with particles.
• Zero measurable pressure drop across the filter.
• Continuous magnetic separation without frequent element replacement.
• Secure particle retention — unlike magnetic drain plugs, particles are not released during operation.

Better than magnetic drain plugs
Magnetic drain plugs collect particles at the sump and have limited surface area; captured material can be disturbed during oil changes or by vibration and re-enter the circuit. Lubretec magnetic filters provide larger collection surfaces and operate in the circulating stream for continuous cleaning.

Seamless integration with existing systems
Lubretec units can be fitted into standard or custom filtration housings and are compatible with the Decolube filter series. Their modular design enables flexible placement and configuration across industrial applications.

Designed for analysis and reliability
Captured particles can be removed and examined microscopically to identify failure modes, wear trends and contamination sources, supporting:

• Root cause analysis (FMEA)
• Predictive maintenance programs
• Oil condition diagnostics

When should magnetic filters be used?

• Systems where ferrous wear particles are routinely produced (gearboxes, pumps, hydraulic circuits).
• Applications requiring strict cleanliness for performance and longevity.
• Maintenance strategies that include oil sampling and condition monitoring.
• Installations where minimizing filter replacements and avoiding pressure disturbances is important.

Summary
Lubretec magnetic filters remove iron and steel particles from circulating fluids using powerful magnets, reducing a primary cause of wear and system failure while maintaining uninterrupted flow and zero pressure drop. They provide a low-maintenance, analysable solution across a range of fluids and operating conditions.
