MFS 3500S
Mid-Size System. Full-Scale Performance.

Designed for Demand
The MFS 3500 is purpose-built for high-efficiency solids control in Horizontal Directional Drilling, microtunneling, and similar trenchless applications. Its mid-size capacity bridges the gap between compact systems and full-scale reclaimers—delivering the flow rate and separation power required for longer bores and more complex utility installations, with cut point performance down to 24 microns.
Scalable for Complex Jobsites
With a 600 GPM throughput and streamlined layout, the MFS 3500 is ideal for contractors who need dependable performance in environments where uptime and space are critical. From urban infrastructure work to remote field operations, it integrates easily with most drill setups—keeping your fluid clean and your timeline on track.

Powerful Performance
The MFS 3500 offers a mid-size, skid-mounted design that integrates easily with a wide range of drilling rigs and support equipment. With a 600 GPM continuous process rate, it supports consistent mud flow and reduces downtime in the field.

Advanced Solids Separation
Two elliptical motion scalping shakers efficiently remove large particles, while twelve 4-inch hydrocyclones target fine solids—ensuring a consistent supply of clean, high-quality mud throughout your operation.

CONSISTENT FLUID CIRCULATION
Equipped with three centrifugal pumps, the MFS 3500 delivers a steady and controlled flow, keeping the mud system balanced and providing optimal pressure for each stage of solids separation.
