LIQUID - CHEMICAL FILTRATION

Multipoly Filter Cartridges - Multi- layer Polypropylene Media.  Pre-filter

Cobetter MutiPoly Filter Cartridges is an all-polypropylene pleated depth filter cartridges. The design adopts depth filter technology for a graded pore size, higher dirt holding capacity, avoids filter surface jams, and eliminate ink contaminants (gels and agglomerates). The graded pore size distribution from coarse (upstream) to fine (downstream) removes particles gradually and extends the filter's service life.

Features and Benefits

- Media constructed of 5-7 layers with a larger pore size on the upstream and a smaller pore size on the downstream. This enables additional particle loading and higher dirt holding capacity.

- Multi-layer Nano Fiber Media eliminates particles according to pore size distribution and sighnificantly increases lifetime.

- Multi-layer Nano Fiber Media provides excellent removal of contaminants capabilities including gels and agglomerates.

- Popypropylene construction yields excellent compatibility wih most ink chemistries.

- Water Treatment

- Potable Water Filtration

- Cooling Water Systems

Cobetter Meltgradient High Efficiency Depth Filter 

Meltgradient series are the PP melt-blown cartridge with the absolute filtration rate. It adopts the reasonable gradient pores configuration, cooperating with the structure of "deep". The cartridge is capable of efficiently capturing particles of different sizes, and its flow rate and life are not inferior to the pleated cartridge. Polypropylene raw material that meets FDA requirements, with extensive chemical compatibility, suitable for filtering inks, coatings, sovents, deionized water,etc.

Features and Benefits

- Particle interception efficiency is up to 99.9%. For the structure with gradient pores, the inner layer is interwoven with high density nano-fibers.

- Long service life, high flow rate. Due to the polypropylene fiber with different linear diameters and unique interwoven density control process, Meltgradient TM has a porosity far beyond that of similar products, which means lower pressure loss across the cartridge and higher dirty holding capacity.

- High purity. Using long fiber fusion and spray process, continuous fiber hot melt interweave into rich and stable pore structure. No adhesive or surfactant, no silicone oil, low preciptate.

- Extensive chemical compatibility. Fully polypropylene structure, complete series with reinforced center bar and optional external frame/end cover, the 68MBCY type. The cartridge can withstand the pressure difference of 4Bar and avoid short circuit of material caused by deformation of cartridge core when using . 

- Wide range of optional filtration rate. It is available from 0.3μm to 120μm, which meets various operating conditions.

Application

- Printing ink, Inkjet ink, dyestuffs

- Automotive Paints, Hard Coatings

- Monomer, polymers, solvent

- D.I water prefiltration and post filtration, R.O water prefiltration, makeup water

Cost Effective EBF Series

EBF economic filter bags are made of high efficiency needle felt, processed by the surface treatments of singeing, calendaring and coating, eliminate the risk of fiber releasing. The seamless thermal bonding technology ensures no side leakage. EBF is available in double layer structure that increases the effective filtration, dirt holding capacity and enhanced retention efficiency. EBF is the cost effective solution for medium-low viscous fluids.

Features and Benefits

- Tight structure and treated surface by singeing, calendaring and coating process, no fiber releasing risk.
- Seamless thermal bonding technology, no side leakage risk.
- Depth filtration media, excellent dirt holding capacity.
- Optional double layer structure provides higher dirt holding capacity and higher retention efficiency than single layer structure.
- Fits the application of medium-low viscous liquids which contains solid or soft particles.

Multi-Round Sanitary Housings. High Flow Sanitary Rate Grade 

Multi-Round Sanitary Housing designed for liquid filtration with vary flow rates.

Flow redesign with flow pattern of side-in and bottom-out reduce cost when compared to bottom-in bottom out flow pattern. In addition, top-inlet opening eliminates the need to move the housing body while installing the filter elements, thus reducing filter change-out time.

Strongly recommended for use in life science filtration applications, it meets sanitary requirements and GMP standards. Features include mechanical polishing with a Ra of 0.3μm, easy-to learn, and thorough drainage, which eliminates concerns about remaining liquids. In adddition, the filter housing is available with a detachable plate for thorough cleanng with strict cleaning requirements.

It is also available in an electro-polish finish for filter housings with 12 rounds or less.

Configurations

H-SCF: bottom-opening, fixed plated; bottom-in bottom-out flow pattern

H-SDF: top-opening and bottom-opening; fixed plate; bottom-in bottom-out flow pattern

H-SEF: bottom-opening; detachable plate; bottom-in bottom-out out flow pattern

H-SFF: top-opening and bottom-opening; detachable plate; bottom-in bottom-out out flow pattern.

Single-Round, Inline-Style, Easy In Cleaning

H-SPF In-line Sanitary Filter Housing is designed and manufactured according to sanitary-grade requirements and GMP standards. Widely used in life-science applications.

Due to the compact design of the top-in and botto-out flow pattern, we recommend to use the filter housings as vent or pipe conector. H- SPF II Filter Housing is designed for filtration with low volume requirements. Small filter elements with 56mm diameter will fit in this housing.

Features And Benefits

- Quality surface finishing- Interal Ra: 0.3μm; External Ra: 0,4μm. Sanitary design prevents entrapment or build-up of contaminants. All electro- polishing is also available.

- Vent & Drain: Threaded sleeve is separated by a stepped thread so that the connection tube will not wave when in draining or venting operation.

- Enlarged vent and drain - interal diameter connects with an 8mm tube.

- Quick-release closure clamp allows for quick disassembly -  our sectional closure clamps increase pressure endurance by 20% compared to normal clamps.

- When running at high operating pressure, quick-release closure clamps provide perfecting sealing for PTFE o-rings. Max. Operating Pressure can reach 10 bar.

- Adjustable nut on the egs allows for filter length to be adjusted.
