The Parker PEACH-Pure™ Series PCLAS provides consistent filtration for a wide variety of fluids. The PCLAS uses PEACH filtration technology to create a thermally bonded, three-dimensional depth filter with a fixed pore structure to classify contaminant capture and maintain consistent efficiency throughout its life. This type of filtration acts as a sieve to focus on retaining targeted particle sizes while allowing smaller non-harmful particle sizes to pass through.
Make the Switch to PCLAS
As resin bonded classifier cartridges exited the market due to environmental impact reasons, including Parkers ProBond™ cartridges, it left a void in the market for a solution. Parker’s team of engineers were able to answer that call with the development of the PEACH-Pure PCLAS cartridge series. It’s all synthetic media and carefully designed depth matrix structure was specifically created to mimic the same classifier filtration performance of the previous resin bonded cartridges. Customer’s who previously used resin bonded cartridges can be confident that the performance of PCLAS will do the job!
PCLAS can be used in place of:
- Parker ProBond PRO
- Pall Hi-V RPN
- 3M/Cuno Micro-Klean RB
- Global Filter GRU-V
- Jonell ECO-RBU
- Nowata Trapper NP
- Matrix MTX resin-dipped string

Depth Filters: Classifier vs. Clarifier
The Parker PCLAS filter is a true classifier. It’s efficiency and corresponding beta ratio do not improve significantly over its life. Instead, the PCLAS classifier filter is focused on strategically maintaining a desired level of performance for as long as possible before requiring filter removal. This design prevents over filtration and stripping out critical components that need to remain within many batch-like applications around the world.

Features
PEACH-Pure Series PCLAS Features:
Parker Engineered Media: Fibers of various sizes are thermally bonded to build, in house, specific filtration media recipes.
Thermal Bonded Fibers: Both individual fibers and media sheets are thermal bonded so no resins are required. This keeps the media pore structure open and provides excellent porosity and permeability.
3-Stage Classification Layers: Classifies particle capture within each layer to target specific sizes while allowing smaller non-harmful particles to pass through.
Conical Helix Flow Pattern: Creates a longer, tortuous flow path in radial, axial and helical directions which increases the probability of contaminant removal.
Rigid Construction: Rigid thermal bonded matrix creates a strong filter tube that prevents contaminant from unloading or channeling as differential pressure increases.
Environmentally Friendly 100% Synthetic Filter Media: Filter media is 100% synthetic and does not contain resins which can be of environmental concern. The media tube can be disposed of by incineration, crushing or shredding.
Silicone Free Construction: Helps prevent craters/fisheyes in inks and paints.

Q & A
PEACH-Pure™ PCLAS Depth Style Classifier Filter Q & A
The Parker PEACH-Pure™ PCLAS is a depth-style liquid filter cartridge designed to provide consistent particle classification throughout the life of the filter. Unlike traditional depth filters that become more restrictive over time, the PCLAS uses a thermally bonded three-dimensional media structure with fixed pore sizes to target and remove specific contaminants while allowing smaller, non-harmful particles to pass through. This helps maintain predictable filtration performance and product quality.
Key benefits:
- Consistent filtration efficiency
- Targeted particle removal
- Reduced risk of over-filtration
- Longer service life
- No resins or binders required
The Parker PCLAS filter is ideal for liquid filtration applications where maintaining specific particle characteristics is important. Common uses include:
- Paints and coatings
- Printing inks
- Chemicals
- Solvents
- Coolants
- Plating solutions
- Water treatment
- Process fluids
- Varnishes and gels
Its classifier filtration design makes it especially valuable in applications where removing desired pigments, additives, or performance-enhancing particles could negatively impact product quality.
The primary difference is that the PCLAS is a classifier filter, while most conventional depth filters are clarifier filters.
Traditional depth filters typically become more efficient as they load with contaminants, which can eventually remove particles that should remain in the process stream. The PCLAS is engineered to maintain a consistent filtration level throughout its service life, preventing over-filtration and helping preserve critical ingredients, pigments, or additives.
PCLAS Advantages:
- Maintains target filtration performance
- Prevents stripping of beneficial particles
- Provides predictable product quality
- Reduces process variability
- Improves batch-to-batch consistency
The PCLAS uses Parker's PEACH® filtration technology, which thermally bonds synthetic fibers together without resins. This construction provides a rigid filter structure that resists channeling, unloading, and media collapse under differential pressure.
Additional benefits include:
- Open pore structure for improved flow
- Excellent contaminant-holding capacity
- Silicone-free construction
- Environmentally friendly synthetic media
- No resin contamination concerns
The PCLAS was specifically developed as a replacement for discontinued resin-bonded classifier cartridges such as Parker ProBond™, Matrix MTX, and Global GRU-V filters.
Yes. The Parker PEACH-Pure™ PCLAS was developed as a direct replacement for several legacy classifier filter cartridges that have been phased out, including:
- Parker ProBond PRO
- Pall Hi-V RPN
- 3M/Cuno Micro-Klean RB
- Global Filter GRU-V
- Jonell ECO-RBU
- Nowata Trapper NP
- Matrix MTX resin-dipped string
The PCLAS delivers similar classifier filtration performance while offering improved environmental characteristics, stronger structural integrity, and more consistent filtration efficiency throughout the filter's life.
