Working principle:

1. The duplex filter is install in the pipeline of hydraulic system .

2. This type duplex filter housing allows continuous operation even if the clogged element need replacing for a clean one .

3. After opening the balance valve and then turning the directional valve , the other filter will begin to work in the lubricating system , the clogged element should be changed at that time .

4. The alarm switch point setting of duplex strainer is 0.35MPa , it can be changed according to customers requirement.

5. This double oil filter is easy operate .

Working media and element type:

1. hydraulic oil : fiberglass filter cartridge , candle filter , multilevel filter

2. lubrication oil: candle filter , multilevel filter

3. heavy oil : basket filter element

4. light oil: fiberglass filter cartridge , candle filter , multilevel filter

5. fuel oil: basket filter element

6. water: basket filter element

Application:

1. This duplex filter is widely used in metallurgical machinery , mining machinery , heavy-duty machinery etc lubricating system.

2. Applicable industries: Fine chemicals, water treatment systems, plup and paper, automobile manufacturing, petro-chemical, machining, coatings, electronics etc. 

3. Applicable liquids: Wide applicability, all liquids contained micro-impurities .

4. Filtration type: One-time intercept filtering, the filter bag need to be replaced manually regularly .

5. Filtration function: Remove all sizes of particles, purify liquids, protection of critical equipment.
