The Parker 12AT Return Filter is designed to clean hydraulic fluid as it returns to the reservoir, capturing contaminants before they re-enter the system. The Parker 12AT features a rugged aluminum head, spin-on canister design, and high-efficiency Microglass, cellulose, or Par-Gel filter media options. It offers multiple port configurations, optional bypass valves, and visual or electrical clogging indicators for easy monitoring and maintenance.

Suction filters clean fluid from the reservoir before it reaches the pump, preventing contamination and wear. The Stauff SUS filter installs directly in hydraulic tanks, features durable construction, stainless steel mesh (60–250 µm), and supports flows up to 400 L/min with an optional 0.2 bar bypass valve.

Pressure filters clean fluid downstream of the pump to protect critical components from contamination. The Parker WPF series is built for high-pressure applications up to 7,000 psi and 137 GPM, offering reliable performance and extended system life. Its durable design includes a ductile iron head, forged steel bowl, and SurgeGuard elements with built-in bypass, reverse-flow valves, and a reusable core for efficient maintenance.

Desiccant breathers dry air entering the reservoir to prevent moisture and particulate contamination. The Parker TriCeptor features a multi-tier filtration system with a 3-micron polyester filter and silica gel desiccant, offering 98.7% efficiency. It’s compatible with 1-inch NPT, NPSM, BSPT, and BSPP threads for versatile use.
