01.E.660.6VG.HR.E.P Filter Element – High-Performance Hydraulic Filtration Solution

1. Product Overview

The 01.E.660.6VG.HR.E.P filter element is an essential component in pipeline-type hydraulic systems, typically installed at 

the inlet filter of hydraulic circuits to remove metal particles and contaminant impurities from fluid media. By ensuring clean oil,

 it protects critical equipment and guarantees normal system operation.

Manufactured with high-quality glass fiber or stainless steel mesh imported from the United States, this replacement element

 offers numerous advantages: convenient contaminant discharge, large circulation area, minimal pressure loss, simple structure, 

compact size, light weight, and uniform filter media. It is designed for direct interchangeability with original specifications—

same dimensions, sealing interfaces, and filtration performance—enabling drop-in installation without housing modifications.

Please note: Aite is an independent manufacturer and not an authorized distributor of the original brand. Our replacement

 elements are engineered to match original performance at a competitive price point.

5. Selection & Operation Guidelines

5.1 Replacement Indication

Monitor the differential pressure gauge. Replace when DP reaches the alarm value—typically 0.35–0.5 MPa above initial clean 

pressure drop. Under typical industrial conditions, replacement every 6–12 months is common, but actual interval depends 

on contamination ingress.

5.2 Storage Conditions

Store unused elements in original packaging in a cool, dry, dust-free environment. Avoid direct sunlight, extreme temperatures,

 and corrosive chemicals. Recommended storage: <40°C and <80% relative humidity.

5.3 Disposal

Used elements may contain hazardous contaminants. Follow local environmental regulations—drain oil and dispose as 

industrial hazardous waste or through authorized recycling channels.

Frequently Asked Questions (FAQ)

Q1: What is the recommended replacement interval for the 01.E.660.6VG.HR.E.P filter element?

A: The interval depends on operating conditions and contamination levels. Monitor the differential pressure gauge—replace 

when DP reaches 0.35–0.5 MPa above initial clean pressure drop. Under typical industrial conditions, replacement every 6–12

 months or after 3,000–5,000 operating hours is common. Shorten intervals for high-contamination environments.

Q2: Can this filter element be cleaned and reused?

A: No. This element is designed for single-use only. Cleaning may damage the glass fiber or stainless steel mesh media,

 reduce filtration efficiency, and cause secondary contamination. Always replace with a new element.

Q3: How do I confirm compatibility with my existing filter housing?

A: Check the model number on your existing element and compare dimensions (outer diameter, inner diameter, length), 

seal type, and bypass valve setting. Our 01.E.660.6VG.HR.E.P follows original specifications for 1:1 interchangeability—no 

housing modifications required. Our technical team can assist with cross-referencing.

Q4: What is the difference between your element and the original brand element?

A: Our element is manufactured using equivalent high-quality imported US glass fiber or stainless steel mesh and premium 

sealing materials, meeting or exceeding original performance specifications (validated by ISO 16889 multi-pass testing). 

It offers reliable filtration performance at 40–60% cost savings with faster delivery times.

Q5: Can this filter element handle high-viscosity or phosphate-ester fluids?

A: Yes. The element is compatible with various hydraulic fluids, including high-viscosity oils and phosphate esters. For phosphate 

esters or high-temperature (>100°C) applications, FKM seals are required—please specify your working medium when ordering.

Q6: What does the "1–100 μm" filtration precision range mean?

A: The series is available in multiple absolute ratings from 1 micron to 100 microns. A 10-micron rating means particles larger

 than 10 microns are captured with high efficiency (β₁₀ ≥ 200). Select the rating based on your system's cleanliness 

requirements—finer for servo-valve protection, coarser for general lube circuits.

Q7: Does this element have an integrated bypass valve?

A: The bypass valve is typically installed in the filter housing rather than in the element itself. Some variants include an integrated

 bypass; others are non-bypass designs. Please verify your system requirements before ordering. Our team can assist in selecting 

the correct configuration.

Q8: What are the consequences of running a system with a clogged filter element?

A: A clogged element increases differential pressure, which may open the bypass valve (if equipped), allowing unfiltered oil to

 circulate and accelerate component wear. If no bypass is present, the pressure drop may cause filter collapse or system 

starvation. Regular monitoring and timely replacement are essential.

Q9: Can I use this element in a suction line application?

A: This element is generally designed for return line or pressure line applications. For suction line applications, a different filter

 design with lower pressure drop and higher flow capacity is required. Please consult our engineering team for specific 

recommendations.

Q10: Can you supply test certificates for export and customs clearance?

A: Yes. Every shipment includes EN 10204 Type 2.1 material certificates, ISO 16889 multi-pass performance test reports,

 and factory inspection documents. Upon request, we can provide Type 3.1 third-party inspection or surveyor reports 

(additional cost applies), meeting EU, ASEAN, Middle Eastern, and South American import requirements.

Q11: Do you keep the 01.E.660.6VG.HR.E.P in stock?

A: Yes. This is one of our popular models and is always well-stocked. Trial orders (1–10 pcs) ship within 3–7 working days; 

bulk orders (500+ pcs) within 15 working days. Expedited airfreight is available for urgent breakdowns.

Q12: Do you offer elements with different seal materials or micron ratings?

A: Yes. Beyond the standard NBR seal and 10-micron rating, we offer FKM seals for high-temperature/aggressive fluids, 

and absolute ratings of 1, 3, 5, 20, 25, and 100 microns. Custom end-cap designs and branded labeling are also available for 

OEM/distributor orders.

Q13: Do you provide technical support for installation or troubleshooting?

A: Yes. Our in-house engineers have 15+ years of hydraulic filtration experience. We provide free dimensional drawings, 

installation guides, and remote video troubleshooting. For large projects, on-site commissioning support can be arranged 

(subject to travel conditions).

Q14: Is the filter media truly imported from the United States?

A: Yes. Our glass fiber and stainless steel mesh media are sourced from leading US manufacturers, ensuring consistent quality 

and reliable filtration performance. All materials are traceable and accompanied by mill test certificates.
