Precisely assess oil cleanliness to safeguard long-term equipment performance
The filterability of lubricating oils directly impacts the reliability and service life of hydraulic systems, engines, and other critical machinery. Excessive contaminants or poor filterability can lead to filter clogging, accelerated component wear, and even system failures.
Designed and manufactured in strict compliance with SH/T 0805-2008, the DFYF-954 Lubricant Filterability Tester is used to evaluate the filtration performance of mineral oil‑based lubricants, particularly hydraulic oils in hydraulic systems. The instrument applies a constant pressure to pass an oil sample through a standard filter membrane, recording filtration time and flow rate. This enables precise determination of oil cleanliness and filtration capability, helping manufacturers and end‑users control oil quality at the source.
Key Features
✔ Fully compliant with SH/T 0805-2008 – authoritative, reliable data
Rigorously follows SH/T 0805‑2008, suitable for mineral‑oil‑based lubricants and especially hydraulic oils with a viscosity grade not exceeding VG 100. Test results carry industry‑wide credibility.
✔ Wide adjustable pressure range – simulates real‑world conditions
Max. air supply pressure: 700 kPa
Adjustable pressure range: 50 kPa ~ 200 kPa
Regulation error: ≤ 5 kPa
Allows simulation of various filtration environments, accurately reflecting actual in‑service filterability.
✔ High‑precision filter assembly – ensures test accuracy
Filter cell volume: 350 mL
Effective filtration area: 1130 ± 60 mm²
Cell pressure rating: >300 kPa
Easy‑to‑disassemble membrane components for convenient routine maintenance.
✔ Dual test modes – versatile operation
Supports both dry and wet test methods, accommodating different oil types and analytical objectives.
✔ Smart touch control – efficient and user‑friendly
Touchscreen display for intuitive parameter setting
Multi‑segment timing with automatic experiment logging
Automatic calculation of key results – stage filterability, permissible deviation *d*, repeatability *r*, and reproducibility R – eliminating manual errors.
✔ Dedicated graduated cylinder – clear volume reading
Includes a specialized cylinder with 10 mL and 300 mL markings for easy observation and recording of filtrate volume.
