DFZ Series Sandwich Plate Filters | Ayater

In the realm of modern industrial hydraulics, space optimization and component protection are paramount. The Ayater DFZ series replacement filters are specifically designed to address these needs through a compact sandwich plate design. Unlike traditional in-line filters that require extensive piping, our DFZ-compatible units mount directly onto hydraulic control blocks. This configuration not only saves valuable machine footprint but also minimizes the risk of leakage points associated with external plumbing.

These filters are critical for maintaining the purity of fluids entering sensitive control components. By positioning the filtration unit immediately upstream of servo valves or proportional directional valves, Ayater ensures that even the finest particulate contamination is captured before it can cause stiction, wear, or catastrophic failure in the control loop. This makes our filters an indispensable component for injection molding machines, machine tools, and mobile hydraulic equipment requiring high-precision movement.

Ayater utilizes high-grade spheroidal graphite cast iron or machined steel for the filter housing, ensuring the unit can withstand the rigorous demands of high-pressure cycling. Rated for operating pressures up to 315 bar (4500 psi), the housing is engineered to resist fatigue caused by pressure pulsations common in heavy-duty duty cycles.

Internal fluid dynamics are optimized to reduce differential pressure (ΔP) across the clean element. The flow path is designed to guide hydraulic oil through the inlet, evenly dispersing it across the pleats of the filter media, and channeling it through the outlet with minimal turbulence. This efficiency lowers the energy consumption of the hydraulic system and extends the service life of the element by preventing localized media stress.

The core of Ayater's filtration performance lies in our proprietary multi-layered inorganic glass fiber media. For the DFZ series equivalents, we employ a depth-filtration structure that maximizes dirt-holding capacity while maintaining a stable Beta ratio (filtration efficiency) even as differential pressure rises.

Standard cellulose filters often suffer from "media compression," where the pores collapse under pressure, releasing trapped contaminants back into the system. Ayater elements are reinforced with epoxy-coated wire mesh support, ensuring high collapse resistance. Whether you are filtering standard mineral oils, lubricating fluids, or synthetic hydraulic fluids, our elements maintain their structural integrity, ensuring that a 5-micron rating remains a true 5-micron rating throughout the element's lifespan.

Designed for ISO 4401 and CETOP standard interfaces, Ayater DFZ replacements allow for "drop-in" installation. There is no need for system modification; the bolt patterns and flow channels (P, T, A, B ports) align perfectly with existing manifold stacks.

Maintenance is streamlined through user-friendly design features. The filter bowl is easily accessible, allowing for rapid element change-outs during scheduled downtime. To support predictive maintenance strategies, our units can be equipped with visual, electrical, or electronic differential pressure indicators. These indicators signal exactly when the element has reached its contamination capacity, preventing premature changes (wasting money) or delayed changes (risking bypass).

Our DFZ-compatible filters are widely deployed in sectors where fluid cleanliness correlates directly with revenue. In the automotive manufacturing sector, they protect the hydraulic presses used for body panels. In wind energy, they ensure the pitch control systems operate smoothly. For marine hydraulics, the robust coating and material selection resist harsh operating environments.

By choosing Ayater, you are not just buying a filter; you are investing in a cleanliness solution that reduces the Total Cost of Ownership (TCO) of your machinery. We bridge the gap between OEM quality and aftermarket affordability, ensuring your hydraulic circuits remain contamination-free.
