Remove foreign particles from food and other sanitary material with these magnetic filters. As material passes through, magnets sealed inside each rod draw metal and other contaminants out. The smooth-ground weld seams and polished surfaces are free of pits and crevices where bacteria could grow, making these filters easy to sanitize. Made from 316 stainless steel, they will not corrode from frequent washdowns with harsh cleaners. These filters are often installed in gravity hoppers, chutes, and bins in sanitary areas, such as food processing lines. They help you comply with Hazard Analysis and Critical Control Point (HACCP) programs.

Filters that are USDA certified meet the highest standards of sanitary design. With extremely smooth surfaces and no sharp corners, every inch of filter can be thoroughly cleaned. They’re polished to a minimum smoothness of 32 Ra, and corners are ground to a 0.125" radius or greater.

Remove contaminants, moisture, and other particles from steam that will touch food and for final filtering in pharmaceutical, biotech, and electronics applications. The cartridge in these housings filters out 98% of particles as small as 1 micron and 100% of particles as small as 2 microns. That’s why they meet 3-A’s accepted practice for creating culinary-grade steam, which is often used in steam-in-place (SIP) cycles to sanitize equipment, and for applications such as blanching. They’re FDA compliant for direct contact with food, and also meet pharmaceutical equipment design standards.

All are made of 316 stainless steel, so frequent washdowns with harsh cleaners and sanitizers won’t corrode them, and they withstand steam. These housings are designed to sanitary standards; they’re 3-A certified 10-04 and meet ASME BPE. They have rounded edges and highly polished interior and exterior surfaces, minimizing the spots where bacteria could grow. For the same reason, they don’t have horizontal ledges—liquid completely drains off.

They connect to your line with two quick-clamp fittings that are easy to take apart for cleaning and line reconfiguration. Each fitting is tightly sealed with an EPDM gasket, which has excellent resistance to steam.

Cartridges can be cleaned and reused, but after six cleanings you should replace them to maintain high performance.

Designed for use in food, pharmaceutical, and other sanitary environments, this precision wire cloth is sintered (fused together) to create a strong, smooth surface that’s free of crevices where contaminants can collect. Made of 316 stainless steel, it won’t corrode from frequent washdowns with harsh cleaners and sanitizers. It complies with FDA design requirements for equipment used with food.

Often used in sieves and vibratory shakers, the openings of this wire cloth have a tight size tolerance for accurate, consistent sifting results. It handles heavier materials and higher washing pressures than our standard precision wire cloth while keeping its tight size tolerance. It also won’t fray.

Remove contaminants from culinary steam—steam that sanitizes food and beverage processing equipment—with these corrosion-resistant filter housings. They’re often used as pre-filters to trap large particles, protecting filters that then capture smaller particles. Made of stainless steel, they won’t corrode from frequent washdowns with harsh cleaners. The cartridge can be cleaned for repeated use, but should be replaced after six uses. These housings comply with FDA design standards for pharmaceutical equipment and are FDA compliant for direct contact with food.

Along with a cartridge, these housings are used in liquid processing lines to filter contaminants and minimize bacteria growth in food and pharmaceutical plants, as well as other sanitary environments. Made of 316 stainless steel, they won’t corrode from frequent washdowns with harsh cleaners. With a self-draining design, rounded edges, and highly polished surfaces, they leave no space for liquids to linger or bacteria to grow. These housings connect to process lines with sanitary quick-clamp fittings that allow for fast disassembly and cleaning. An EPDM rubber gasket maintains a tight seal and resists water, detergents, chemicals, and steam. The gasket is FDA compliant for direct contact with food. Housings are 3-A certified for sanitary design standards and comply with FDA pharmaceutical equipment design standards.

Cartridges (sold separately) are pleated, creating a large surface area for trapping debris. They have one open end with an EPDM rubber O-ring and locking tabs—the O-ring creates a tight seal to ensure that liquids pass through the cartridge for filtration, while the locking tabs help align with cartridges for a secure fit. Cartridges are FDA compliant for direct contact with food.

Cartridges with a polypropylene filter are often used as pre-filters in liquid processing lines, capturing larger particles to prevent clogging.

Cartridges with a PES filter remove extremely small particles, so they’re commonly used as final filters in high-purity applications. They’re also known as absolute-rated cartridges.
