How about a portable hydraulic oil filtration system?

Portable hydraulic oil filtration system is an efficient and flexible oil purification solution, especially suitable for on-site maintenance, emergency treatment or space-constrained working conditions. The following is a detailed analysis of its core features, application scenarios and purchase recommendations:

Core advantages of portable hydraulic oil filtration system

1. Efficient purification capacity

- Multi-stage filtration: integrated coarse filtration (100μm), fine filtration (1~10μm) and adsorption filtration (optional), effectively remove particles, moisture and oxides.

- Dehydration technology: Some models are equipped with vacuum dehydration or coalescence separation technology to reduce moisture to ≤100 ppm.

- Fast cleaning: The processing flow rate is usually 20~200 L/min, which is suitable for fast maintenance of small and medium-sized systems.

2. Portable and flexible

- Compact design: small size (such as suitcase size), light weight (20~50kg), optional pulley or handheld design.

- Easy to move: suitable for field operations, high-altitude platforms or narrow workshops.

- Power adapter: supports 220V/380V AC or DC (such as 24V vehicle power supply).

3. Intelligent control

- Real-time monitoring: built-in sensors display flow, pressure difference and moisture content (some high-end models).

- Automatic protection: automatic shutdown in case of overpressure and overheating to avoid equipment damage.

4. Economical

- Reduce oil change costs: extend the life of hydraulic oil by more than 50% and reduce the cost of waste oil treatment.

- Reduce downtime: immediate on-site treatment can be carried out to avoid equipment downtime for maintenance.

Key parameters for procurement

1. Filtration accuracy

- General hydraulic system: 5~10μm (ISO 4406 17/15/12).

- Servo system: 1~3μm (ISO 4406 14/12/9).

2. Flow matching

- Small equipment: 20~50 L/min (such as excavator hydraulic oil tank).

- Medium-sized system: 50~150 L/min (e.g. hydraulic station for injection molding machine).

3. Dehydration capacity

- Coalescing type: moisture is reduced to 100~200 ppm.

- Vacuum type: moisture ≤50 ppm (needs to be heated to 50℃).

4. Power supply and power

- Electric type: light, but dependent on power supply.

- Diesel drive: suitable for non-electrical environment, but noisy.

5. Certification standards

- Explosion-proof requirements: ATEX or GB 3836 (chemical/mining scenarios).

- Environmental certification: RoHS, leak-free design.

Comparison of mainstream brands

| Brand/model | Features | Applicable scenarios | Price range |

|-----------------------------------|---------------------------------------|---------------------------|-----------------|

| Pall Mobile Clean | 1μm absolute filtration accuracy, with β value detection | Aviation, precision hydraulics | 10,000~20,000 |

| Hy-Pro ECO Compact | Coalescing and dehydration, 30 liters/minute, weighing only 15 kg | On-site maintenance of construction machinery | 3,000~5,000 |

| Donaldson PTF400 | Diesel drive, 100 liters/minute, IP65 protection level | Wind power, ships | 8,000~12,000 |

| China SINO-NSH PF series | Vacuum dehydration, cost-effective | Daily maintenance of factories | 20,000~40,000 |

Limitations

- Large flow limit: usually no more than 200 liters/minute, not suitable for continuous filtration of large hydraulic stations.

- Deep contamination treatment: Severely emulsified or oxidized oil still needs to be returned to the factory for treatment.

Portable hydraulic oil filtration system is a powerful tool for on-site maintenance, especially suitable for rapid impurity removal, emergency dehydration and regular maintenance. When purchasing, you need to match the model according to the flow demand, filtration accuracy, and environmental requirements, and give priority to lightweight and intelligent design.
