Filter Bags

FDA/EC Conformity
All polypropylene materials used in manufacturing comply with the regulations of the Food and Drug Administration (FDA), title 21 of the Code of Federal Regulations Section 177, and EC Regulations 1935/2004 and EC Directive 2002/72/EC, as applicable for food and beverage contact.

Cost-effective filter bags for demanding applications

• ABP polypropylene filter bags are fabricated from hydrophobic microfiber filter material, which require pre-wetting with an aqueous solution (full details about wetting and installation are provided with every box of ABP filter bags)
• Highly efficient melt-blown filter material in polypropylene with graded density profiles to maximize dirt-holding capacity and prolong service life
• No additives such as resins, binders or surface treatments
• Spunbond polypropylene cover layer virtually eliminates fiber migration
• Unique UNI-WELD process for bottom seam provides a stronger, more flexible weld seal
• Fully-welded construction with patented SENTINEL® seal ring provides 100% bypass-free filtration
• The pressure-activated SENTINEL seal ring provides a flexible, chemically resistant seal which adapts to any bag filter housing.

About Extended Life Filter Bags (POEX/PEEX)
The Extended Life filter bags (POEX and PEEX) provide outstanding performance on many types of contaminants such as gels, particles with wide ranges of sizes, and particles with various irregular shapes. The coarse, pre-filtering layer is designed to provide long service life, capturing a large amount of contaminants without excess surface loading. The POEX has been field-proven to hold up to twice the amount of contaminants as a standard felt bag, reducing waste volume and bag changes. The Extended Life filter bag is ideal for automotive coatings, chemicals, resins, edible oils and other fluid applications.

Features

• Excellent filtration on many contaminants - gels, particles with wide range of sizes and particles with irregular shapes
• A coarse inner layer, graded pore structure, greater depth than standard bags provides
• excellent filtration performance
• Available in polyester (PEEX) and polypropylene (POEX)
• Twice the standard dirt-holding capacity of traditional felt bags to provide longer service life, fewer change-outs and reduced waste
• Polypropylene bags are FDA compliant
• Micron rating for polypropylene 5-100; polyester 1-100
• PolyWeld® seam construction with hermetically sealing Polyloc® ring eliminates liquid bypass
• Glazed finish eliminates unwanted fiber migration

About MAX PONG Filter Bags
The PONG Heavy Duty Extended Life filter bag (MAX PONG) is the leader in high-efficiency, low-cost filtration. Its seamless micro-fiber graded density cartridge insert removes trace oils that frequently occur in process fluids, and provides four times the dirt-holding capacity of conventional polypropylene bags. Combined with its welded seam felt cover and Polyloc® ring for elimination of unfiltered bypass, it becomes the perfect choice for uses where longer-lasting, high-efficiency filter bags are needed. The MAX PONG Heavy Duty Extended Life filter bag is ideal for continuous flow applications such as e-coat and phosphate baths, and batch applications including oils, edible oils and syrups, or any final or polishing filter requirements.

Features

• High-efficiency, low-cost filtration is ideal for continuous flow applications
• Welded seam construction eliminates unfiltered bypass due to needle holes
• Large dirt-holding capacity and lower pressure drop provide long service life
• Adsorbs smaller particles and filters wide range of particle sizes
• Pure polypropylene microfiber insert contains no sizing, bonding adhesive, resin, lubricant, silicone or antistatic chemicals
• FDA compliant to meet food grade government standards
• PolyLoc® ring creates hermetic seal to prevent liquid bypass

About Polyweld® Felt Filter Bags
Polyweld® filter bags hold a distinct advantage over all types of needle-sewn bags. The welded seams completely eliminate the possibility of unfiltered liquid bypass occurring due to needle holes. The result is a tighter seam, high bag efficiency and improved finish product yields. In addition, the fused edges of the Polyweld bag provide a fiber-free finish and virtually eliminate unwanted fiber migration. Since the Polyweld bag is not constructed with thread, the possibility of silicone contamination from this source is also removed. FSI’s Polyweld filter bags are available in several different media: standard polypropylene felt, extended life polypropylene felt, and standard polyester felt.
 
Features

• Welded construction of bags completely eliminates unfiltered liquid bypass from occurring due to needle holes
• Available in standard polypropylene, polyester and extended life felt for broad range of product compatibility
• Glazed finish eliminates fiber migration for clearer results
• PolyLoc® ring creates a hermetic seal that prevents liquid bypass and produces clearer results
• Polypropylene is FDA food grade compliant to government standards
• FDA Compliant Polyester felt is available (non-standard)
• Silicone free to eliminate cratering for improved surface results
• Available from stock for quick delivery

Higher Efficiencies Using PTFE Filters

• With its unique physical properties, Cleanmake Products  filters with PTFE membrane are able to out perform nearly all other filter constructions in many applications. Among its many useful properties, PTFE is hydrophobic (Literally “afraid of water”) meaning it repels water. Additionally, it has a very low coefficient of friction of 0.05 – 0.10 (meaning substances have a hard time sticking to it and are easily removed) and has a high melting point of approximately 325°C.
• Stricter governmental regulations for particulate emission are on the horizon. The new EPA PM2.5 standard for particulate matter emissions will present additional challenges for facilities to reach compliance. Be ready to meet the challenge by employing high efficiency PTFE filter bags in your Cleanmake Products .

• PTFE filter bags from Cleanmake Products .com can reach amazing efficiencies when operated deployed correctly. PTFE filters from Cleanmake Products .com can easily reach sub-micron filtration ranges. In some applications efficiencies are high enough to allow for the recirculation of treated air back into the facility. Use of such “Green Technology” further promotes an environmentally friendly operation, and saves on heating costs.

Efficiency Claims Confirmed By EPA Testing
Independent testing conducted under the EPA’s Environmental Technology Verification (ETV) program has proven that PTFE Membrane filters are capable of ultra high efficiencies. Tests of PTFE filter bags from several different manufacturers showed particulate matter outlet emissions as low as 0.0006 gr/ACF (1.3mg/m3). In most size ranges the test PTFE fabrics showed zero emissions during testing. Emissions data were below the detection limits of the testing equipment. The fractional efficiency percentages were 100%, only dipping to 99.98% with particle sized 0.3-0.5 (μM).*

The Benefits of Surface Filtration Over Depth Filtration

• PTFE membrane filters also have a distinct advantage over non-membrane filters due to differences in the way they filter out particulate. Non-PTFE membrane filter bags employ depth filtration to filter particulate. Depth filtration is accomplished when a layer of dustcake forms on the outside of the filter, and an accumulation of dust particles is deposited in the depth of the filter. In coming particles are captured as they follow the tortuous path through the dustcake, and depth of the filter. As time goes on, more and more particles get trapped within the filter, leading to higher pressure drops and eventually filter “blinding” which reduces filter life.
• Cleanmake Products  filters with a PTFE membrane however employ surface filtration to remove incoming particles. The PTFE membrane works as the primary filter cake, collecting all of the particulate on the surface. This keeps the particulate from penetrating the filter fabric, which can lead to reduced airflow, and filter “blinding”.
• Additionally, with traditional filters larger than normal emission occur during start-up and immediately following the cleaning cycle due to lack of primary dustcake. With PTFE filters, this problem is largely eliminated.

PTFE Fabric Combinations
PTFE membrane can be applied to a large variety of fabric substrates depending on the particular application. Contact a Cleanmake Products .com representative to help you to determine which combination of fabric and PTFE membrane is the best fit your particular process environment.  Below is listing of several popular PTFE / Fabric combinations
