Customizable DFP/DFPF filter with optional bypass valve, FPM/EPDM seals and LED clogging indicator, the high-performance DFP pressure filter delivers tailored filtration solutions for all industrial hydraulic system requirements.
Ayater's DFP and DFPF manifold block mounted pressure filters offer comprehensive customization options to meet the personalized filtration needs of different industrial hydraulic systems, on the basis of standard 315bar nominal pressure, -30°C~+100°C temperature range and multi-size coverage (60-1320) for the DFP pressure filter line. The customizable options include built-in bypass valve in the filter head, FPM/EPDM alternative seals (standard NBR), LED light for clogging indicators, HFA/HFC emulsion compatibility and custom bypass cracking/clogging indicator pressure settings, with all customized designs complying with international hydraulic standards and ensuring structural and performance stability. The customization process is simple, with the model code adding suffixes to identify customized functions (e.g., B6 for 6bar bypass, V for FPM seals, L24 for 24V LED), making the product model clear and easy to identify and track. All customized units undergo the same strict quality testing as standard products, including pressure resistance, fatigue strength and filtration efficiency tests, to ensure the reliability of customized functions across the entire product range.
The optional built-in bypass valve in the filter head has a standard cracking pressure of 6bar, and can be customized to other pressure values on request, ensuring that the hydraulic fluid bypasses the clogged filter element and the system continues to operate when the pressure loss exceeds the set value. This component for the DFP pressure filter is made of high-strength alloy material, with excellent sealing performance and fatigue resistance, no leakage under rated pressure, and the opening and closing response is sensitive, avoiding excessive pressure loss in the system.
The standard NBR seals can be replaced with FPM or EPDM seals (V suffix) for high-temperature working conditions or special hydraulic fluids, expanding the applicable temperature range and improving the compatibility with polar fluids. The W suffix customization makes the filter suitable for HFA and HFC water-based emulsions, with anti-corrosion treatment on the internal metal parts to prevent rust and corrosion, ensuring the long service life of the DFP pressure filter in water-based fluid systems.
The standard VD differential pressure indicator can be equipped with LED light (L24/L48/L110/L220) for remote and visual fault warning, with two light-emitting diodes for 24V voltage to improve the warning effect. The pressure setting of the clogging indicator can be customized (DFP: non-5bar, DFPF: non-8bar) to match the unique pressure loss characteristics of different hydraulic systems using a DFP pressure filter.

The customizable DFP and DFPF filters are widely used in customized hydraulic systems in aerospace, automotive manufacturing, precision machinery and other heavy industries that rely on reliable fluid filtration from a DFP pressure filter. For example, the FPM seal + 110V LED indicator customization is ideal for high-temperature hydraulic systems in automotive painting lines, where the robust design withstands extreme thermal conditions; the HFA emulsion compatibility + 8bar custom bypass customization is used in food processing machinery's water-based hydraulic systems , with the DFP pressure filter delivering corrosion-resistant performance in aqueous fluid environments; the two-piece filter bowl + dual indicator customization is applied in large-scale metallurgical hydraulic systems to improve maintenance efficiency and fault monitoring accuracy. The manifold block mounting design of customized filters is fully compatible with standard manifold blocks, and the customized functions do not change the external installation dimensions, enabling seamless integration with the original system without additional design and modification. Ayater provides professional technical support for system integration, including pressure drop calculation, element selection and customization scheme design, to ensure that the customized filter matches the system performance requirements.
All DFP and DFPF filters (standard and customized) are produced in accordance with ISO international standards, with raw material inspection, process monitoring and finished product testing throughout the production process, and the certificates and approvals can be provided on request.
