The Decolorization Filter Cartridge is a specialized filtration solution designed for oil purification and liquid decolorization applications. This element is engineered to remove pigments, odors, organic contaminants, and fine particles from industrial fluids, restoring oil quality and extending equipment life .
Decolorization filters are essential components in oil regeneration systems where hydraulic oils, lubricating oils, transformer oils, or other industrial fluids have darkened due to oxidation, thermal degradation, or contamination . The 150×570 cartridge utilizes fiberglass media to adsorb colored compounds, volatile organic compounds (VOCs), and odorous substances from the fluid stream .

Q1: What is the difference between a decolorization filter and a standard particulate filter?
A: A standard particulate filter captures only solid particles through mechanical sieving. A decolorization filter adds adsorption capability—using fiberglass media to remove dissolved contaminants such as pigments, odors, oxidation byproducts, and organic compounds that pass straight through mechanical filters .
Q2: What causes oil to darken, and can it be restored?
A: Oil darkens due to oxidation, thermal degradation, and accumulation of contaminants over time. These degradation products include colored colloids, sludge precursors, and organic acids. Yes, oil can be restored using decolorization filters that adsorb these contaminants, returning the oil to a lighter, clearer state and extending its useful life .
Q3: What is the typical service life of this 150×570 decolorization cartridge?
A: Service life depends on the contaminant load and operating conditions. Factors affecting life include:
Initial oil condition: Darker, heavily oxidized oil saturates the media faster
Flow rate: Higher flow rates may reduce contact time and adsorption efficiency
Operating temperature: Optimal performance typically around 40-60°C
Typical service life ranges from 200-800 hours of operation. Monitoring pressure drop is the most reliable indicator for replacement.
Q4: Can this filter be cleaned and reused?
A: No. Decolorization filters are designed for single use. The adsorption sites within the activated carbon become saturated over time and cannot be regenerated through simple cleaning. Once the adsorption capacity is exhausted, the element must be replaced.
