Clean Visco Series Nylon6 Polyamide Filter
Clean Visco Series: High-Performance Nylon 6 Polyamide Filtration for Refineries
In the aggressive environments of Amine, Glycol, and Hydrocarbon processing, standard polypropylene filters often fail. The K Filter Clean Visco Series is engineered with advanced Nylon 6 Polyamide microfibers, specifically designed for high-temperature stability and toxic fluid compatibility. Whether managing solvent purification or amine sweetening loops, these melt-blown cartridges provide a rugged, depth-filtration barrier with a 90% retention efficiency for critical process integrity.
The Science of Thermal Resilience
Clean Visco Series: The High-Temperature Polyamide Shield for Refineries
“In the world of Amine sweetening and Glycol dehydration, temperature is the enemy of filtration. While standard filters soften and bypass, the K Filter Clean Visco Series utilizes a high-performance Nylon 6 matrix that remains rigid at 120°C. By engineering a ‘washable’ Polyamide structure, we don’t just provide a filter; we provide a high-durability asset that survives the most toxic environments in the oil and gas industry.”

The Nylon 6 Advantage: Engineered for Extremes
The Clean Visco Series is built for the “Hardest Jobs” in the refinery:
High-Temperature Resilience: Unlike Polypropylene (limited to 60-80°C), our Nylon 6 matrix thrives in elevated process temperatures, maintaining structural integrity up to 120°C (248°F).
Aggressive Chemical Compatibility: Specially formulated for Amines, Glycols, Ketones, and Hydrocarbons. The Polyamide fibers are naturally resistant to the “swelling” caused by aggressive industrial solvents.
Washable & Renewable Design: The high-strength Nylon 6 fibers allow for a washable type application in specific industrial cycles, extending the service life and reducing the Total Cost of Filtration (TCOF).
Microbial Interception: Engineered with a specific fiber density to assist in “killing” or intercepting germs and bacteria within process fluids, ensuring the biological purity of your closed-loop systems

FAQ: Clean Visco Nylon 6 Series
1. Why use Nylon 6 instead of Polypropylene?
Polypropylene is excellent for water, but it can dissolve or soften when exposed to hot hydrocarbons and certain solvents. Nylon 6 (Polyamide) is a “high-energy” polymer. It remains rigid and effective in hot Amine and Glycol streams where standard filters would collapse or bypass.
2. Is the Clean Visco Series truly “Washable”?
Yes. Due to the high mechanical strength of the Polyamide fibers, these cartridges can be surface-cleaned or back-flushed in specific low-viscosity applications. This is a massive cost-saving feature for Refineries in the USA and Europe looking to minimize hazardous waste disposal.
3. How does it help with “germs and bacteria” in industrial fluids?
In Glycol and Water-based systems, biological growth can cause severe fouling. The Clean Visco Series utilizes a dense microfiber matrix that physically traps and “kills” bacterial colonies by intercepting them at the 0.1 to 1-micron level, preventing the formation of biofilm in your heat exchangers.
4. Can I use these for High-Temperature Hydrocarbons?
Absolutely. The Clean Visco series is the preferred choice for Refinery distillation and high-temp oil polishing. It maintains its micron rating even under high differential pressure (ΔP) at temperatures exceeding 100°C.
5. What is the benefit of the 90% Efficiency rating?
In Refinery and Petrochemical loops, a 90% retention (nominal-plus) is the “Engineering Sweet Spot.” It provides sufficient clarity to protect downstream equipment while allowing for the high flow rates and lower pressure drops required for massive industrial throughput.

Technical Battle Card: Clean Visco (Nylon 6) vs. Standard PP
| Feature | Standard PP (Polypropylene) | Clean Visco (Nylon 6 Polyamide) |
|---|---|---|
| Max Operating Temp | 60°C – 80°C (140°F – 176°F) | 120°C (248°F) – High Temp Capable |
| Hydrocarbon Resistance | Poor (Swells/Softens in hot oil) | Excellent (Oleophilic & Rigid) |
| Amine/Glycol Stability | Limited (Material degradation) | Superior (Designed for Gas Sweetening) |
| Mechanical Strength | Moderate (Flexible) | Extreme (High Tensile & Durable) |
| Reusability | Disposable / Single-Use | Washable / Renewable Design |
| Solvent Compatibility | Poor for Benzene/Toluene/Ketones | Excellent for Aggressive Solvents |
| Fiber Migration | Risk at high temperatures | Zero (Thermally Bonded Nylon) |
| Efficiency | Up to 99.98% (Absolute) | 90% High-Retention (Refinery Grade) |
Why Polypropylene (PP) Fails in Refineries
“The Temperature Wall”
Softening Point: As temperatures approach 70°C, PP fibers begin to soften. This causes the “pores” to expand, leading to bypass where dirt slips through the filter.
Hydrocarbon Sensitivity: In the presence of hot oils or aromatics (Benzene/Xylene), PP can actually “swell,” which increases pressure drop (ΔP) prematurely and can lead to the cartridge collapsing.
One-Time Use: PP is a soft polymer; once it is clogged with sticky refinery “crud,” it cannot be cleaned without destroying the fiber matrix.
2. Why Clean Visco (Nylon 6) Wins
“The Chemical Fortress”
Thermal Rigidity: Nylon 6 maintains its crystalline structure at temperatures where PP would melt. This ensures your 0.1µm to 50µm rating stays accurate even in boiling-hot process streams.
The “Washable” Advantage: Because Nylon is a much tougher polymer, the Clean Visco series can be surface-cleaned or back-flushed with steam or solvent to remove surface “cakes,” allowing for multiple uses in certain industrial cycles.
Oleophilic Nature: Nylon naturally attracts oil while repelling water. This makes it a “Magnetic” filter for removing oil droplets from Amine or Glycol water-based loops, which is a major pain point for refineries.

FAQ: Material Choice in Toxic Environments
Q: Is Nylon 6 compatible with Ketones and Esters?
A: Yes. While PP struggles with many aggressive organic solvents, Nylon 6 Polyamide is specifically engineered to resist the chemical “attack” of esters, ketones, and alcohols common in chemical manufacturing.
Q: Why is the efficiency 90% instead of 99.98%?
A: In high-viscosity refinery fluids, a 99.98% absolute filter would clog in minutes. 90% Efficiency is the industry standard for Refinery Depth Filtration because it provides the best balance of protecting downstream equipment while allowing for the high flow rates required in 24/7 operations.
Q: Can the Clean Visco be used in Steam lines?
A: While Nylon 6 has high-temperature resistance, it is best suited for liquid phase hydrocarbons and chemicals. For pure high-pressure steam, we would typically recommend our Stainless Steel or Glass Fiber series, but for Hot Condensate, Nylon 6 is an excellent choice.
