This absolute-rated, 100% polypropylene, pleated cartridge features Advanced Pleat Technology (APT) that increases the usable filtration surface area while maintaining standard industrial cartridge dimensions. The service life of a pleated cartridge is often dictated by the accessible surface area. Conventional pleated filters may offer a large gross surface area, but when the media is packed too tightly into the cartridge, only part of the surface area is usable resulting in both flow restrictions and limited contaminant holding capacity. The `blind` or unusable area commonly occurs near the inside diameter where the pleats are packed most tightly. The Betafine XL series filter cartridge is manufactured using a staggered pleat configuration that, when combined with a novel support material, provides more open space between the pleats.

Laboratory testing and field experience has shown that Micro-Klean™ RB Series Filter Cartridges hold up to 2 or more times the contaminant by weight than competitive products with equal retention ratings. Our manufacturing produces a rigid, resin bonded, graded porosity structure that reduces by-pass and avoids the unloading traits of soft, deformable melt blown and string wound filter cartridges. We combine the principles of surface and depth filtration into our Micro-Klean™ RB Series Filter Cartridge line to provide enhanced filter service life, particle removal efficiency and optimum flow characteristics. Standard series filter cartridges are available in this line in multiple lengths with or without various end treatments to fit most major manufacturer’s cartridge housings.

Validated 0.2 and 0.1 micron rated membrane provides reliable sterilizing filtration. Excellent contaminant capacity, flow rates, and life resulting from robust double-asymmetric membrane layer filter construction. Hydrophilic asymmetric polyethersulfone membrane enables wet out in aqueous solutions for integrity testing. 100% forward flow Integrity tested prior to release. 21 CFR compliant materials of construction and other documentation supports validation and regulatory submissions. We combine two asymmetric polyethersulfone (PES) membrane layers with Advanced Pleat Technology in manufacturing LifeASSURE PDA Series Filter Cartridges, creating a filter that provides high throughput and fast flow. These filters have applications in pre-filtration and sterilizing filtration in the pharmaceutical, biological, and bioprocess industries where low protein binding is critical.

The 3M DF series filter media consists of 2 layers with the first layer being “open” to remove the larger contaminants while the second layer is “tighter” to remove the smaller contaminants. Our graded porosity structure provides greater contaminant holding capacity and longer life than conventional single layer media. Compared to conventional felt filter bags, 3M DF series filter element provide up to 4 times the service life, superior contaminant reduction efficiency, enhanced flow per filter and reduced losses associated with frequent filter change-outs.

The 3M Commercial HVAC Filter MERV A11 Mini-Pleat with Gasket combines excellent filtration performance with low airflow resistance and long filter life. Our filters improve air quality and HVAC performance to potentially save users time and money. The 3M Commercial HVAC Filter MERV A11 Mini-Pleat with Gasket is built around addressing the heating, ventilating and air conditioning (HVAC) needs of our customers and can be used without a pre-filter. The filter’s sturdy, long-lasting design provides a number of benefits to the end user, beginning with an easy installation process.
