18. Remove the suction and discharge wands/hoses and place one into each ring
located on the side of the cart. Place the wand/hose tip into the tray to catch any
remaining fluid. An absorbent pad can be placed into the tray to absorb any fluid
remaining in the wands/hoses. Otherwise disconnect the wands/hoses and store.
Filter Selection and Run Time
Filter selection
is determined by what cleanliness level is recommended for your oil.
The selection of the appropriate cleanliness level should be based on the operational
and environmental conditions as well as recommended manufacture specifications.
Consult your equipment manufacture whenever possible. A guideline of gear oil
cleanliness is included in the next section.
Start with a larger filter and work your way down. A common mistake is over-filtering
contaminated oils. The finer the filter, the more frequent the replacement of the element
will be required. Generally speaking as the oil viscosity increases the filter size should
get larger because cleanliness levels are less.
Run time
is determined when the filtration unit is used in a kidney loop filtration and
works best when oil is filtered six to ten turns of the reservoir volume. To calculate the
minimum hours of operation use the following formula:
Minimum minutes = Reservoir Gallons x 6 (Divide by 3 for Cart)
*Multiply this number by 3 for hand held Min Hours
Maximum minutes = Minimum minutes x 2
In rare cases, or extremely dirty oil, additional run time may be needed.
Filter Element Technical Data
Filter element life varies with the true dirt holding capacity of the element under dynamic
flow conditions and the amount of contamination introduced into the Filtration System.
Choosing the right media for the correct application is determined by the rate of
ingestion with the desired ISO cleanliness level. The amount of dirt can vary from day to
day and hour to hour, making it difficult to predict when an element will become fully
loaded. Increasing the rate of fluid flow increases the ability of the filter to trap particles.
The effectiveness of the filter elements should be determined by contamination
monitoring. Our oil analysis laboratory has a wide range of oil analysis capabilities to
help determine and trend fluid conditions.
High Water Content Fluids
High water content fluids consist of either water and soluble mineral based oil, or water
and soluble synthetic oil. The oil proportion is usually 5% but may vary from 2% to 10%.
All Trico particulate filter medias are compatible with these types of fluids and should be
used in leu of the Trico water removal filters. However, the high specific gravity and low
vapor pressure of these fluids can create a potential for severe cavitation; therefore,
