Metal Cutting Vacuum Filtration Systems
Metal cutting vacuum filtration systems remove chips, fines, and sludge from metalworking fluid so your machines run on clean, consistent coolant.
Since 1979, manufacturers like yours have installed more than 6,000 Hydro-Vac systems worldwide, in configurations that run a single machine or a central line supporting up to 60 machines at once.
The platform filters mineral oils and both soluble and synthetic coolants, and it's built as a modular product line so the system fits your shop floor instead of forcing your shop floor to fit the system.
How Hydro-Vac Vacuum Filtration Works
Vacuum filtration systems draw dirty coolant through a filter media bed under vacuum pressure, pulling out solids before the fluid returns to your machines.
The Hydro-Vac runs this cycle automatically, so production doesn't stop for manual cleanout or waste removal.
The system monitors coolant condition continuously and adjusts to keep downstream equipment running at its target performance level.
Cleaner, longer-lasting coolant means fewer fluid changeouts, fewer unplanned stops for filter service, and tool life gains that show up in your cost per part.

Vacuum Filtration Capacity and System Range
Every Hydro-Vac system is sized to the application rather than selling a fixed configuration.
The application engineers and system designers work with your process data and run preliminary testing in our lab to confirm filter media selection and flow capacity before you commit to a system.
Capacity: Handles 100-10,000 gallons per minute (GPM).
Built-In Features and Accessories
Every Hydro-Vac system supports two or more machines running through one filtration line, so if one machine goes down for service, the rest keep running on filtered coolant.
That redundancy is built into the automation, not added on after the fact.
The accessory catalog extends the base system for operations with specific requirements:
- Temperature control for coolant conditioning
- Secondary filtration for super-clean operations
- Magnetic filtration for ferrous fines removal
- Mixed metal filtration for shops running multiple materials through one line
And mist collection integration is recommended to manage shop air quality alongside your coolant system, through our Stealth Mist Collection line
Removing contaminants from coolant also reduces what your shop sends to waste disposal and cuts back on the abrasive and corrosive exposure that damages machine components and puts operators at risk around tanks and sumps.
Industries and Applications We Serve
Vacuum filtration supports metal cutting operations across many industries, from OEM machine tool builders specifying filtration into new equipment to plants standardizing coolant management across an existing line.
Common entry points into a vacuum filtration project include:
Hardware Upgrade: replacing an aging or undersized filtration setup
Central Coolant Systems: consolidating multiple machines onto one filtration line
Turnkey Installation: a new line or new facility built around central filtration from the start
Individual Machine Filtration: starting point for shops not yet ready for a central system

Frequently Asked Questions
Vacuum filtration pulls dirty coolant through a filter media bed under vacuum pressure to remove chips, fines, and sludge before the fluid returns to your machines.
And the huge advantage is that it runs continuously and automatically, without stopping production for manual cleanout.
The Hydro-Vac vacuum filtration systems handle metalworking coolant flows from 100 to 10,000 GPM.
A single Hydro-Vac system can support up to 60 machines running at the same time, so you can start with the machines you have today and grow the system as your shop adds capacity.
Yes. Hydro-Vac vacuum filtration handles mineral oils and both soluble and synthetic metalworking coolants. Our applications engineers test your specific fluid in the lab before recommending a filter media and system configuration.
Vacuum filtration uses vacuum pressure to pull fluid through a media bed, which handles fine, mixed particulate well.
Magnetic filtration removes ferrous fines with magnetic rollers instead of media, and rotary drum filtration uses a continuous belt-fed drum for higher-volume, larger-particulate chip loads.
You'll get help matching the method to your chip load and fluid type during the application review.
