BINXIU Cutting Fluid Filter Paper, 50cm x 100m

Product: BINXIU Cutting Fluid Filter Paper, industrial grade emulsions, mixed fiber. Size: 50cm x 100m with a 2.2 kg roll weight. The material blends polyester fiber with polymer membranes to achieve stable filtration and high tensile strength. Temperature tolerance ranges from -10°C to 120°C, and the fabric resists corrosion from typical industrial oils. Best for shops needing durable, long rolls with precise filtration requirements. Choose this if you prioritize material stability and wide-size options. Caution: verify compatibility with your exact coolant chemistry before use.
Cutting Fluid Filter Paper — 50cm x 100m

Product: Cutting Fluid Filter Paper for industrial filtration. Material: mixed fiber, 50cm x 100m (19.6in x 328ft). Filtration particle size around 25–30 microns; effective at removing metal particles, sludges in cutting fluids, emulsions, grinding oils, and related solutions. Pros: stable properties, minimal corrosion risk, broad temperature tolerance (-10°C to 120°C). Cons: relatively low liquid absorption means it does not soak up coolant aggressively, which can extend fluid life but may require replacement more often in very dirty systems.
LIKCBNVMOU Industrial Filter Paper — 50cm x 100m

Product: Industrial Cutting Fluid Filter Paper Roll by LIKCBNVMOU. Size: 50cm x 100m with 25–30 micron filtration. Features a high-permeability mesh for large flow and minimal resistance. The material shows strong chemical resistance and can withstand a broad temperature range (-10°C to 120°C). Best for facilities needing high filtration efficiency with low coolant loss. Consideration: ensure your system’s flow rate matches the paper’s high-permeability design to maximize benefits.
HAZEK Industrial Oil Residue Filter Paper — 70cm x 100m

Product: HAZEK Industrial Oil Residue Filter Paper. Size: 70cm x 100m, weight around 2.6 kg per roll. Made from mixed fibers with high filtration accuracy and efficiency. Features advanced mesh forming technology and reinforcement for consistent tensile strength from start to use. Best for heavy-duty filtering in grinding and bearing operations. Limitation: larger roll size may require bigger storage and handling space.
HTRY Industrial Filter Paper — 30cm x 100m

Product: HTRY Industrial Filter Paper for various cutting fluids and lubricants. Size options include 30cm x 100m (and other sizes). Notable for corrosion resistance to cutting fluids, acid/alkali resistance, and a wide operating range (-40°C to 120°C). Best for applications requiring chemical stability and broad environmental tolerance. Choose this if you need robust performance across challenging fluids and temperatures. Caution: verify compatible with your specific coolant chemistry to avoid unexpected interactions.
Buying Guide: Key Considerations For Coolant Filter Paper
- Filtration rating: Common choices include 25–30 microns. Smaller micron ratings capture finer particles but may increase pressure drop and replace frequency. Match micron rating to your debris level and fluid type.
- Material and construction: Mixed fiber with polymer membranes offers a balance of strength and filtration accuracy. Consider whether you need high tensile strength for heavy flows or a lower absorption to minimize coolant loss.
- Size and roll length: Lengths like 100m are common, but width varies from 30 cm to 70 cm and beyond. Choose a size that fits your filtration setup and replacement interval.
- Temperature and chemical compatibility: Look for papers rated from -40°C to 120°C and resistance to the specific coolants used in your shop. Corrosion resistance extends paper life in harsh fluids.
- Flow and pressure considerations: High-permeability designs improve flow but may compromise filtration tightness. Evaluate your system’s pump capacity and required filtration efficiency.
- Compatibility with machine tools: Consider whether your coolant system handles grinding, milling, or bearing oils, as some papers are optimized for certain fluids.
- Size availability and replacement logistics: Availability of multiple widths helps fit non-standard systems. Plan for storage space for rolls and spares.
Frequently Asked Questions
- What micron rating should I choose for coolant filtration? A: Typical ranges are 25–30 microns for industrial emulsions. Lower micron ratings filter finer particles but may reduce flow; select based on debris level and system capacity.
- Are these papers compatible with all cutting fluids? A: Most are designed for common metalworking oils and emulsions, but always verify chemical compatibility with your specific fluid mix.
- Do filter papers affect coolant life? A: Yes, by trapping solids and metal sludges, they can extend coolant life when replaced regularly and matched to system demand.
- What are the signs I need to replace the filter paper? A: Increased filter resistance, rising particle buildup in recovered fluids, or deteriorating fluid clarity indicate replacement is due.
- Can I use these papers with CNC grinding machines? A: Yes, several products are designed for CNC grinding, milling, and metalworking fluids with appropriate micron ratings and tear resistance.
- Is a larger roll always better? A: Larger rolls reduce downtime but require more storage and handling space. Choose a size that aligns with your workflow and maintenance plans.
