What oil filtration systems are suitable for construction sites?

Construction site oil filtration systems primarily treat diesel and hydraulic oil, with the core goal of protecting equipment and extending oil life.

Core Solutions:

1. Mobile Fuel Truck: 

Used for diesel/lubricant oil refueling, featuring integrated coalescing and water removal, and particle filtration (3-10μm precision), ensuring oil cleanliness at the source.

2. Precision Oil Purifier:

 Used for hydraulic oil treatment, featuring high-precision filtration (1-3μm), coalescing, or vacuum dehydration, for circulating and purifying tank oil.

3. Duplex Filter: 

Installed in equipment piping, enabling non-stop filter element replacement and protecting critical hydraulic components.

Critical Selection Key:

- Accuracy: Hydraulic oil requires 1-5μm (pay attention to the β value), diesel requires 3-10μm.

- Flow Rate: ｓｅｌｅｃｔ based on tank size (e.g., 20L/min).

- Safety: Explosion-proof certified (Ex series) is preferred, and materials include carbon steel or stainless steel.

- Brand: Choose Pall and Parker for international applications; choose Nojia and Hitech for domestic applications, offering excellent value.

Recommended configuration: A mobile diesel refueling truck + a hydraulic oil precision oil filter, which covers most needs, effectively reduces failures and saves maintenance costs.
