PROCESS FILTRATION
WELD PACKS
Purolator Multiple Layers of Wire Woven Cloth Spot Welded Together
Weld packs are made from multiple layers of wire woven cloth spot welded together. We offer a wide range of products as well as customized products based on your filter needs. Our large stainless steel wire woven cloth inventory enables us to be the cost leader in providing screen packs.
Why should you choose our Multti-Layer Screen Packs (Weld Packs)?
- Multiple layers of wire woven cloth spot welded together
- Plain steel mesh
- Stainless steel wire woven cloth
- Alloys available: Inconel®, Monel®, Hastelloy®
- Other woven cloths in brass, copper, or galvanized steel
- Wide variety of weaves
- Available ratings range from 2 - 200 microns
- Engineered lay ups to optimize performance to meet required flow rates, pack pressure, and specified filtration levels
SINTERED PACKS
Purolator Sintered Fiber Metal Felt
Sintered fiber metal felt media is available in micron ratings as low as 2.5µ, has a very high porosity, and thus provides a very low-pressure drop. The media can be fabricated into tubular form, or pleated to provide increased filter area. The media can be configured as a depth media, and has a much higher dirt holding capacity than either sintered metal powder or woven wire cloth.
Features
- High strength
- No media migration
- Continuous operating temperature range of -50°C to 550°C (-65°F to 1000°F)
- Stainless steel construction
- Corrosion resistant
- Filtration from 1 micron to 200 micron
- Custom configurations including layers of perforated plate, fiber metal felts and photo-etched foil
- Abrasion resistant
- Easily fabricated into virtually any shape, size or configuration
- Precise pore size distributions and fluid flow permeability
- Dimensionally stable
- Excellent weldability
- Easily cleaned
- Most standard sheets in stock for immediate delivery

POLYMER DISC FILTER
High Performance Polymer Filtration
Constructed from sintered wire cloth laminates or sintered non-woven fiber metal felt media, these polymer leaf disc filters are the product of choice for polymer film and specialty polymer producers. The unique design and configuration of the leaf disc assembly maximizes the effective filtration area while minimizing the residence time of the polymer itself, thereby reducing the risk of polymer degradation.
Features & Benefits
Available media and micron ratings
Porofelt® diffusion-bonded fiber metal felt depth media are available from 3µ - 60µ absolute. Poroplate® sintered wire cloth media is available from 10µ- 200µ absolute.
Materials/method of construction
Polymer leaf discs are available in 316L stainless steels and other alloys. These alloys, combined with our advanced construction/welding methods, result in excellent corrosion resistance and a useful life of many cycles.
FRAMED PACKS
Purolator - Multiple Layers of Wire Woven Cloth Encapsulated In An Aluminum Binding
Frame packs are made from multiple layers of wire woven cloth encapsulated in an aluminum binding. We offer a wide range of products as well as customized products based on your filter needs. Our large stainless steel wire woven cloth inventory enables us to be the cost leader in providing screen packs.
In addition to 316L stainless steel, other metals and alloys are available to meet your special requirements, such as greater temperature and corrosion resistance.
Stainless Steel: 316L, 204L, 310L, 347, 430 - Hastelloy C-276, C-22, X, N, B, B2 - Inconel 600, 625, 690 - Nickel 200 and Monel 400 (70Ni - 30Cu) - Titanium - Alloy 20 and many others.
Why choose Purolator Frame Packs?
- Multiple layers of wire woven cloth encapsulated in an aluminum binding

- Stainless steel wire woven cloth
- Alloys available: Inconel®, Monel®, Hastelloy®
- Other woven cloths in brass, copper, or galvanized steel
- Wide variety of weaves
- Banding material is available in a variety of thicknesses, band widths, and materials (stainless steel)
- Framed packs reduce changeout time due to easier and safer handling, and improved sealing
- Rigid form helps control the flatness of the pack improving sealing and consistency of product
- Sizes are compatible with OEM Screen Changers
- Available ratings range from 2 - 200 microns
POLYMER CANDLE FILTERS
For High-Temperature, High Pressure Polymer Processing Applications
.
Features & Benefits
Laser-marked end fittings
Each element is permanently laser-marked for ease of identification and traceability.
304L/316L stainless steel media
All elements are made from 304L or 316L stainless steel filter media. They are ideal for repeated cleaning cycle temperatures up to 850° F and highly corrosive applications.
Extended filtration area
Computer modeling optimizes the number of pleats and pleat height to maximize the filtering surface area. In fact, pleated elements have over 3-4x the filtering area as cylindrical elements. This means lower differential pressures, greater dirt-holding capacity and longer on-stream life.
Quality control
Every polymer filter element is bubble-point and air flow tested prior to shipment to ensure product integrity and performance.
Applications
- Synthetic fiber (PET, PA, PP, carbon & more)
- Film (PP, PET, PC, PS, PVBH, PE, & more)
- Non-woven (PP, PE, & more)
- PET bottle
- Engineered polymers
- Rubbers and silicones
