High Efficiency Filtration for Superior Liquid Clarity

Strainrite's absolute-rated polypropylene depth cartridges are designed to optimize throughput while achieving absolute and repeatable effluent quality. Our filter media is constructed on the latest continuous microfiber blowing equipment that accurately controls fiber diameter and integrity. Utilizing state-of-the-art, on-line monitoring equipment, Strainrite delivers the industry's most uniform media, ensuring unparalleled product consistency. Our 100% polypropylene construction provides an expansive chemical compatibility range for your most demanding applications. All materials of construction meet USP Class VI and CFR 21 requirements for food and beverage contact.

Strainrite's nominally rated polypropylene depth cartridges are designed to reduce overall filtration costs when compared to spunbonded, stringwound, and nominally-rated pleated cartridges. This polypropylene media is designed and manufactured on state-of-the-art meltblowing equipment to Strainrite's strict specifications for high solids-loading requirements for a variety of prefiltration applications.

Strainrite's Select (High Solids Loading) Polypropylene Depth Cartridges offer a unique, absolute rated, gradient density, polypropylene depth filter that utilizes the revolutionary HSL technology in combination with our high efficiency micro-fiber meltblown media.

X-TRA Life filter bags utilize state-of-the-art needling technology providing outstanding filtration performance in a variety of applications.

Strainrite's pleated charged nylon membrane cartridges are manufactured with highly retentive, naturally hydrophilic, nylon membranes that have an added cationic, positively charged, functional group. The positive surface charge or positive zeta potential, provides enhanced retention of smaller negatively charged particles such as endotoxins by electrokinetic mechanisms.

Strainrite's pleated polyethersulfone membrane cartridges were developed for the filtration of process fluids that require a high degree of particle retention and/or constant bacterial barrier for effective sterilization.

Strainrite's pleated nylon membrane cartridges are highly retentive, naturally hydrophilic nylon membrane filters that are specially designed for critical filtration requirements of aqueous fluids.

Strainrite's pleated polysulfone membrane cartridges were developed for the filtration of process fluids that require a high degree of particle retention and/or constant bacterial barrier for effective sterilization.

Strainrite's sterilizing grade pleated polyethersulfone membrane cartridges are engineered to meet the highest standards of microorganism control for sterile fluids. These filter elements are validated for complete removal of Brevundimonas diminuta (ATCC 19146) at test concentrations of 107 CFU/cm2 (Colony Forming Units).

Strainrite's pleated PTFE membrane cartridges were developed for critical filtration applications where PTFE and polypropylene materials are compatible.

SPMF High Efficient Filter Bags are an excellent choice over cartridges for many applications and still offer absolute filtration. A series of different sieve opening layers achieves maximum surface area and longer life exceeding cartridge life substantially. SPMF bags do offer lower operating cost and still maintain the use of existing filter housings without the expense of new capital equipment.

The Strainrite Companies is known for developing some of the industry's most advanced designed hybrid cartridge elements on the market. These high efficiency filter elements require a vessel that has a hermetically sealed top to fully capture all of the filters capabilities. The SRC Industrial Duty Cartridge Vessel is perfectly positioned to handle standard cartridges and absolute rated filters.

The SRCT and SRVT sanitary cartridge vessels offer the aesthetics and operational durability of stainless steel at affordable prices. The SRCT's innovative design ensures optimal cleanability in critical areas and can accommodate either 10", 20" or 30" cartridges in a single cartridge housing and 20", 30" or 40" filter cartridges in a multi-cartridge vessel.

The SRHD Heavy Duty series is designed to handle your most difficult fluid filtration requirements. Our SRHD is made from heavy duty steel components and to strict quality standards, which allows our clients the ability to change from a non-stamped to an ASME UM stamped vessel at a nominal cost. The SRHD series incorporates our unique radial seal design that provides a hermetic seal between the basket and vessel. Utilizing a radial seal with our retainer baskets eliminates "basket rocking", which causes bypass as the basket becomes out of round. "Basket rocking" is common in low cost bag vessels that do not incorporate an O-ring seal and can cause unfiltered liquid bypass. The Strainrite Companies' SRHD, with a radial seal, has a machined surface that produces a positive seal to eliminate bypass. SRHD vessels incorporate a combination of unique qualities that places us at the top of single bag vessel design. Standard features include: a recessed basket, volume displacer welded to top cover, and a 304 stainless steel wire mesh basket to name a few. Our standard wire mesh baskets increase available filtration surface area up to 30% compared to cheaper perforated retainer baskets.

The SRID Industrial Duty series incorporates our unique radial seal design that provides a hermetic seal between the basket and vessel. Utilizing a radial seal with our retainer baskets eliminates "basket rocking", which causes bypass as the basket becomes out of round. "Basket rocking" is common in low cost bag vessels that do not incorporate an O-ring seal and can cause unfiltered liquid bypass. The SRID, with a radial seal, has a machined surface that produces a positive seal to eliminate bypass.

The SRL Low Flow Vessel is versatile in its ability to function as a strainer or add a filter bag and convert it to a liquid filtration housing unit. The SRL series vessels come in two standard sizes, tailored to your throughput requirements. The SRL 1-25 is rated for 30 gpm, and the SRL 1-50 at 65 gpm. All sizes are available in three different closure designs for ease of cleaning/replacing and for easy removal without specific tools.
