BHA® Preveil® ePTFE Membrane Laminated Filter Bags

High Efficiency Filtration For Dust Collector

BHA Preveil is made from PTFE resin, a substance with inherent non-stick properties that can be used to help your dust collector operate at maximum efficiency by providing:
• 99.99% efficiency
• Higher airflow
• Better cleaning
• Optimum emissions control

Media. Size. Construction. A lot of careful consideration goes into choosing the ideal filter for your dust collector. That’s where we come in. Our global team of industry specialists has decades of experience in the application of ePTFE membrane filter bags across a wide variety of industries. We’ll help you evaluate your options and select the right filtration solution that can help you improve operations and optimize baghouse performance. 

It’s not just the quality of the membranes we make that sets us apart—it’s what we do to them. Using our core competencies in membrane extrusion, lamination and finishing treatments, we design BHA Preveil membrane filter bags to improve filtration efficiency and operate at consistently low
differential pressures. This helps reduce filter changeouts and energy costs, extends filter service life, and can help lower particulate emissions across a wide range of applications.

Innovative Pleated Filter Elements Offering Proven High Performance And Durability

Whether used in new systems or serving as retrofits to existing dust collection equipment, these innovative pleated filter elements prove to be a versatile and cost-effective solution. 

Our pleated filter elements deliver valuable benefits:

• Provide superior filtration efficiency
• Promote better airflow for increased throughput
• Reduce air-to-cloth ratios
• Reduce operating differential pressure
• Reduce compressed air consumption
• Eliminate the need for cages
• Are easily installed and removed

Best of all, installation typically requires no modification to existing equipment. You can enjoy improved performance and energy savings without the expense of costly modifications.

Spunbond Media

The media is manufactured by the layering and calendering of fine denier fibers, it features a tight pore structure that better resists particulate penetration. Physically rigid, it can hold a pleat without the support of backing material and withstand temperatures up to 265° F (130° C). Spunbond media, when pleated and molded into the filter, can increase filtration surface area 3 to 4 times more than conventional filter bags. This can lead to a dramatic increase in filtration efficiency while operating at a significantly lower differential pressure. 

Most Versatile And Economical Solution For Capturing Dust And Dry Pollutants

A Wide Range Of Applications 

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.

Innovative Clean Air Solutions

Cobetter Melt Blown Filter Cartridges

Cobetter melt blown filter cartridges are made of polypropylene non-woven with no surfactants, binders, or adhesives. These fiters have long service life and high dirt holding capacity. They are suitable for the water treatment industry.

Features And Benefits

- 100% pure polypropylene depth filter with high dirt holding capacity .
- No wetting agents, solvents, surfactants, or binders, or adhesives .

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
