Understanding filtration options is crucial for selecting the right solution for your specific application. Efficient filtration, suited to particular customer requirements, reduces overall cost and contributes to increased uptime.
Total cost/price
Don’t overlook the cost of poor filtration and other issues that cause downtime.
Efficiency Killers
Problems that shut down or slow machines and shrink efficiency— such as bacteria issues in coolant.
Range of Options
Know your filtration options before determining whether you need a simple mesh filter box or a more complex system.
Projected Future Requirements
Design choices early in the selection process can provide for future expansion.

Filtration Options
Cartridge filtration
This efficient alternative to conventional high-pressure and reverse-flow filters removes ingressed contamination before it flows downward to sensitive components. These simple, modular filters block pump-generated debris before it gets to servo or proportional valves. A high-pressure filter, it provides durability and consistently high performance.
Cyclonic filtration
This waste-free coolant filtration system removes particulates through centrifugal force. It eliminates the need for disposable paper or cartridge filters. Bubbles and foam are not produced. Contaminants, concentrated in the sludge pot, cannot return to the coolant tank once they are removed
Bag filtration
Relatively inexpensive and readily incorporated in machine tool applications, bag filters provide solutions for removing swarf, small chips, and various particulates. Unfiltered liquid enters the housing above the bag and passes down through it. Solids contained in the bag are easily removed when the unit is serviced. Fluid bypass is prevented because the outside diameter of the filter bag seals radially against the housing inside diameter. A single cover gasket seals the opening. Covers can be installed and removed without tools.
Chip Disc Filtration (CDF)
Hennig’s patented CDF filtration systems, compared to many competitors’ systems, offer the advantage that they can be used with a scraper belt or a hinged belt to remove fine, stringy, bushy and broken chips. Drum systems, by comparison, require two conveyors (a hinged belt conveyor and a scraper belt) when there are stringy chips. This dual installation increases maintenance cost and consumes added floor space.
Drum filtration
A drum rotates in a tub of liquid to be filtered. This filtration type prevents clogs in systems with slurries and liquids with a high solid content.
Magnetic filtration
This method is used to remove iron particles. A large magnet attracts and filters these particles from the system. It is suited to environments with ferrous, para-magnetic, and grinding medium issues.

Coolant skimmers: This mechanical system separates oil or particulates floating on the surface of a liquid.
Paper filtration
These systems cleanse various types of liquids (water, emulsions, aqueous solutions) of polluting solid particles. They can be used in machine tool markets as well as chemistry, food, painting, petrochemistry, glass, and industrial washing machine applications. Filtration models are possible for oil.
