GT-MAG — Patented Gravity Tunnel Magnetic Separator
The GT-MAG is K Factor's proprietary inline magnetic separator, featuring a patented Gravity Tunnel design that delivers fully automatic, maintenance-free ferrous particle removal with zero downtime. The Gravity Tunnel is an inclined channel through which process liquid flows under gravity — as the liquid decelerates through the tunnel, it is exposed to a powerful magnetic conveyor that captures ferrous particles on the magnet surface.
Captured particles are automatically discharged to a collection tube as the magnetic conveyor cycles, while clean fluid flows into a separate second-phase compartment. The GT-MAG's unique Crystal Ball — a clear inspection window — allows operators to visually verify filtration performance at any time without stopping the system or opening any components.

Key advantages
- —Technology: Patented inclined Gravity Tunnel with magnetic conveyor — fully automatic self-cleaning
- —Operation: Zero downtime — no scheduled cleaning cycles, no operator intervention
- —Verification: Crystal Ball inspection window — visual performance confirmation at any time
- —Applications: Coolant circuits, degreasing baths, process water with ferrous particle contamination
- —Advantage vs drum separators: No rotating drum to maintain; no scraper blade alignment; no motor speed management — gravity drives the process
The GT-MAG is the right choice for moderate ferrous loading and circuits where the process fluid layout is compatible with gravity-assisted decelerating flow. For higher-intensity applications, see the PAC-MAG (12,800 Gauss) and the K-MAG (80% better capture).
Still running media filters that consume rolls every few hours in grinding?
K Factor's 30-day free trial is available for magnetic separation systems. We assess your ferrous particle loading, fluid type, flow rate, and downstream filtration system. We commission the appropriate GT-MAG, PAC-MAG, or K-MAG inline in your circuit. You run it for 30 days and measure the reduction in media consumption, coolant clarity, and tool life. If the results don't justify the investment, return the system. No invoice. No commitment.
Available to qualifying facilities in the United States, Canada, UAE, Saudi Arabia, and other markets.
