High Pressure Four-2-One™

Metal Felt Filter Elements

• Four times the dirt-holding capacity*
• Long service life
• Minimal resistance to flow (low pressure drop)
• High strength
• Cleanable

SWIFTFELT™ filter media (random metal fiber) filtration is at the core of Swift-JB International high pressure elements. Random metal felt provides high quality filtration technology below 60 microns. It provides absolute particle retention, very long life and exceptionally high dirt-holding capacity.

Compared to other filter media such as wire cloth, sintered metal and non-metallic filters, SWIFTFELT media provides up to a fourfold advantage. Although more expensive, random metal felt offers clear advantages over other media. Its high temperature, high pressure and corrosion resistance, combined with almost unending cleanability, makes it highly economical for hostile environments.

SWIFTFELT metal felt filter media is made with thin filaments of nonwoven stainless steel. These porous felt filter elements are also ideal for highly corrosive or highly viscous applications. They feature extremely high porosity (up to 85%), high flow rates (up to 20 times higher than other media types), and very long on-stream life.

SWIFTLOC™ Construction

These elements are constructed using the SWIFTLOC process with a mechanical lock that leaves no heat history, which means no tendency to carbonize in high temperature applications or during severe cleaning procedures — a problem of earlier manufacturing techniques. The SWIFTLOC assembly process employs a compression joint, permanently clamping the pleated cylinder to the end fittings.

SWIFTFELT metal felt filter elements have a random matrix of 316L stainless steel filaments with diameters from 4 to 25 microns. The finer the micron, the more open area is provided in a pure crosshatch pattern. When sinter bonded, this random matrix can provide:

• Extreme high porosity (up to 85%)
  • high flow rates: up to 20 times higher than other media types
  • long on-stream lifetime
  • excellent flow distribution
• Low pressure drop: The high porosity of our metal fiber media allows a very low pressure drop (and thus lower energy cost), even at high filtration velocities
• High strength: The sintering process creates strong fiber bonds and guarantees a high strength filter medium. Combined with an appropriate inner core, our filter elements can withstand thermal shock and high differential pressures, up to 4500 PSID (310 bar).
• Heat and corrosion resistance: Our filter media can be used in high temperature (up to 500° F) and in corrosive fluid applications
• Can be used for surface or depth filtration: Our filter media enables you to achieve high efficiencies through a cake build-up (surface filtration) and also offer high dirt holding capacity for depth particles capture (depth filtration)
• Stainless steel and other alloys available: not brittle, chemical cleaning is possible, weldable, low thermal expansion, maintains structure (no thermal shock). Depending on the performance you require, we select the proper alloy to provide the required resistance and strength

A Cleanable Element

SWIFTFELT elements can be cleaned and re-used. Ultrasonic, solvent or high temperature methods can all be used and are selected based on element service conditions.
