Mikro-Pleat™ Pleated Filters Overview

Menardi's Mikro-Pleat Pleated Filters can vastly improve the performance of your pulse jet baghouse with no baghouse alterations. Mikro-Pleat pleated filters provide a simple retrofit for upgrading existing dust collection systems and improving problem systems.

Filter Area

The Mikro-Pleat pleated filter is a one-piece element of spun bond polyester media. Because spun bond material is pleatable, we can get 200 - 300% more filter media into a pleated filter that is the same size, or usually smaller than the conventional filter bag it replaces. This dramatically reduces your air-to-cloth ratio, providing for a much more efficient operation of the collector. You will also see increased airflow, lower differential pressure, lower energy cost and higher filtration efficiencies.

Efficiencies

The non-woven, spun bond filter media in the Mikro-Pleat pleated filter has a smooth calendered finish that maximizes dust cake release. Mikro-Pleat pleated filters resist surface penetration by the collected particulate, resulting in much higher cleaning efficiency and faster regeneration of operating airflows. The felt fabrics used in conventional filter bags have millions of rough surface fibers that can attach to the dustcake causing poor cake release. Actually, the felt fabric requires a considerable depth of dustcake to reach an acceptable level of efficiency. The smooth finish of the spun bond media allows for easy release of particulate. This material, offering 99.99+% efficiency, rivals membrane materials at a much lower cost.

Mikro-Pleat pleated filters are used successfully in the following applications:

• Current dust collector systems using polyester material.
• Current collectors that are undersized, requiring additional cloth area.
• Current collector systems using materials other than polyester operating at 250° F or below.
• Current dust collector systems requiring more efficient media.
• Hydrolysis or moisture problems with current standard felts.

Options

Mikro-Pleat pleated filters are available in a variety of sizes and configurations to suit any requirement. The following are just a few examples of what we offer:

• Bottom-load pleated filters to fit MikroPul® (5"), Flex-Kleen® (6") and MAC® (6") style collectors.
• Pop-Top® top-load pleated filters to fit 5.0", 5.0625", 5.25", 6.0", and 6.25" cell plate holes.
• Mikrotex® PTFE laminate finish.
• Oil and water repellent finish.
• Metalized finish for static dissipation.
• Stainless steel / copper ground wires.
• Polypropylene and metal inner core.

Additional Benefits

Mikro-Pleat spun bond media is sturdy and self-supporting. That means we don't have to rely on closely spaced, dust clogging pleats necessary with paper…or the cage support system required with conventional felt bags.

• Eliminate cage costs.
• Reduce change-out costs and process downtime through 50% faster installation.
• Cut pressure drops, dramatically reduce compressed air consumption.
• Avoid collected product contamination, and increase filter life through soap and water cleanup.
