Pressure Filtration Systems for Metalworking and Industrial Coolant
These Verti-Press pressure filtration system pumps process fluid through a bank of vertical pressure filters, pulling sediment and debris out of coolant, cutting oil, and wash water before it goes back into your process.
The system runs as a fully automatic dewatering filter.
It separates solid product from slurry, washes the cake clean, dries it with compressed air, and discharges it without an operator standing over the machine.
Thousands of metalworking and steel plants use it to keep central coolant systems and cutting fluid loops running clean between service intervals.
How the Verti-Press System Works
The Verti-Press design skips the clamshell mechanism most pressure filters rely on. Patented pneumatic seals close and hold each chamber under pressure during the filtration cycle.
Once solids build up on the media, compressed air pushes the remaining liquid through the cake, driving fluids like cutting oil out for cleanup and reuse.
A horizontal chamber design keeps the filter cake forming evenly across the plate, so every chamber pulls its share of the load instead of one section doing most of the work.
Chambers stack vertically to keep the footprint down in machine shops and steel plants short on floor space, and because each chamber runs independently, you can isolate one for service without shutting the rest of the system down.
Built for Metalworking, Steel, and Coolant Reclamation
Construction is typically carbon steel, which keeps the equipment durable and cost-effective. Automatic media discharge clears the filter after every cycle, so the system is ready for the next load without a manual reset.
That combination of durability and hands-off operation is why the equipment shows up most often on coolant, cutting oil, and wash water lines in metalworking and steel operations, where fluid turns over constantly and downtime for cleaning adds up fast.
Features and Benefits at a Glance
Beyond the mechanics, the Verti-Press design pays off in a handful of ways plant managers notice day-to-day.
- Plant hygiene and safety: sealed chambers keep process fluid and solids contained through the full cycle instead of exposed at a clamshell joint.
- Sub-micron precision: filtration down to sub-micron levels for tighter control over fluid cleanliness.
- Full automation: PLC and HMI controls run the cycle, so operators aren't manually cycling the filter.
- High flux rates: the system keeps pace with production schedules instead of becoming the bottleneck.
- Compact footprint: fewer moving parts and a vertical chamber layout keep the equipment out of the way on a crowded plant floor.
Filtration Area and Sizing
Your Verti-Press will be sized to the job, with models ranging from 25 to 400 square feet of filtration area.
A machine shop running one central coolant loop and a steel mill filtering several wash water lines need different footprints, so bring your flow and solids-loading numbers to our applications engineers before you settle on a chamber count.
Where This System Fits
Plants running central coolant systems for CNC and machining operations are the most common fit for the Verti-Press, since shared coolant loops pick up tramp oil and metal fines fast and need constant cleanup to stay usable.
If you're filtering at the individual machine rather than a shared loop, the individual machine filtration equipment covers that scale instead.
The same design also runs chemical and mining dewatering lines outside metalworking entirely.

FAQs
Answers to the questions plant engineers and facility managers ask most before spec'ing a Verti-Press system.
It pulls sediment, debris, and solid product out of slurry, then dewaters and dries what is left for automatic discharge. Metalworking and steel plants use it most often to clean up coolant, cutting oil, and wash water.
Patented pneumatic seals hold the chamber closed under pressure during filtration, which is what lets Filtra Systems skip the traditional clamshell mechanism other pressure filters use.
Filtration area ranges from 25 to 400 square feet, sized to the flow and solids load of your process.
Who else wants help matching a chamber count to their operation?
Yes. Multiple chamber setups run independently, so you can isolate a single chamber for maintenance while the rest of the system keeps filtering.
Construction is typically carbon steel, chosen for durability and cost.
