Hydrostatic (Belt) Filters are filters designed to effectively separate solid particles and dirt in liquids, especially used in industrial applications.
Hydrostatic band filters are industrial filtration solutions designed to separate solid particles, metal chips and contaminants from process liquids. DELTAFIL filter papers, available in different grammage options such as 35 gr/m², 40 gr/m² and 60 gr/m², help support stable filtration performance in hydrostatic filtration systems used in machining, grinding and industrial production processes.
In CNC machining centers, grinding machines and metal processing lines, cutting and cooling fluids become contaminated with fine metal particles, chips, sludge and other residues during operation. If these liquids are not filtered effectively, coolant performance may decrease, cutting tools may wear faster, surface quality may be affected and production costs may increase.
What Are Hydrostatic Band Filters Used For?
Hydrostatic band filters are used to remove solid particles from industrial liquids and help keep process fluids cleaner for a longer period. They are especially important in applications where coolant, cutting fluid or process liquid must remain stable to protect tools, improve surface quality and support production continuity.
By separating particles from the liquid, hydrostatic filtration systems can help extend coolant life, reduce machine contamination, minimize tool wear and improve the consistency of the machining process. The correct filter paper selection is therefore an important part of efficient fluid management in industrial production.
DELTAFIL Filter Papers
DELTAFIL filter papers are specially developed for hydrostatic filtration systems and are supplied in roll form. They are designed to work with hydrostatic filtering machines and provide stable filtration performance in industrial applications. Different grammage options allow users to select the most suitable filter paper according to particle load, liquid type and filtration requirement.
DELTAFIL 303 — 35 gr/m²
DELTAFIL 303 is a 35 gr/m² filter paper developed for hydrostatic filtration systems. It can be preferred in applications where stable filtration, coolant life extension and improved surface quality are required. Its lighter grammage structure can be evaluated for processes with suitable particle load and flow expectations.
In grinding machines and CNC machining centers, DELTAFIL 303 helps separate fine particles from cutting and cooling fluids. This supports cleaner fluid circulation, helps reduce tool wear and contributes to more consistent machining quality.
DELTAFIL 503 — 40 gr/m²
DELTAFIL 503 is a 40 gr/m² filter paper designed for hydrostatic filtering machines. It offers a balanced option for applications that require reliable filtration performance, stable flow and effective particle separation. It can be used to help protect coolant quality and support production efficiency.
This filter paper is suitable for industrial production lines where contaminated cooling liquids may reduce machining performance. By helping remove metal particles and contaminants from the liquid, DELTAFIL 503 supports longer coolant life, better surface quality and reduced production interruptions.
DELTAFIL 506 — 60 gr/m²
DELTAFIL 506 is a 60 gr/m² filter paper option for hydrostatic filtration systems. Its higher grammage makes it suitable for applications where stronger filtration media may be required. It can be evaluated for processes with heavier particle load, more demanding filtration needs or applications where durability of the filter paper is important.
Choosing DELTAFIL 506 can help improve filtration consistency in production environments where coolant contamination is more intense. It supports cleaner process liquids, helps protect machinery components and contributes to more stable production quality.
Why Filtration Matters in CNC and Grinding Processes
During machining and grinding operations, small metal particles and abrasive residues can circulate inside the coolant system. These contaminants may damage tools, affect dimensional accuracy, reduce surface quality and increase machine maintenance requirements. Effective filtration helps control these risks by keeping the fluid cleaner.
Cleaner process liquids can improve heat transfer, support cutting performance, reduce unwanted scratches on the workpiece surface and help maintain more predictable production conditions. For this reason, filter paper quality and correct grammage selection are important for long-term process efficiency.
How to Choose the Right Filter Paper
The correct hydrostatic filter paper should be selected according to the machine type, liquid type, particle size, contamination level, required flow rate, filtration sensitivity and production conditions. A lighter filter paper may be suitable for lower particle loads, while a higher grammage option may be preferred for more demanding filtration requirements.
DELTAFIL 303, DELTAFIL 503 and DELTAFIL 506 offer different grammage alternatives for hydrostatic filtration systems. Selecting the right option helps improve filtration stability, coolant performance, tool life and production quality.
Benefits of Using Hydrostatic Band Filter Papers
Hydrostatic band filter papers help extend the service life of cooling and cutting fluids by removing unwanted particles from the liquid. This can reduce fluid replacement frequency, lower operational costs and support more sustainable production practices.
They also help reduce tool wear, improve workpiece surface quality, protect machinery components and support uninterrupted production. In high-volume industrial environments, these advantages can directly affect productivity, maintenance planning and total production cost.
Industries Using Hydrostatic Band Filters
Hydrostatic band filters and DELTAFIL filter papers can be used in CNC machining, grinding, metalworking, automotive manufacturing, machinery production, heavy industry, tool manufacturing and other industrial processes where cutting fluids or cooling liquids require continuous filtration.
