Offline filtration is a valuable resource for lubrication experts who can use it to keep the oil clean without interfering with the operation of the equipment. You can also clean oil periodically using a filter cart. When it comes to ensuring the reliability of production processes, filter carts can play a key role. In most industrial facilities, filter carts are often used to process fluids that need filtration regardless of viscosity grade or chemical composition, which is not a good practice. It’s important not to misuse filter carts.

As technology and lubrication practices have changed over the years, the use of maintenance tools like a filter cart has gone from being something that was just used on critical equipment to something essential to every lube room.

While maintenance practices have been completely reshaped and an increasing number of businesses place a heavy emphasis on equipment reliability and healthy lubrication practices, manufacturers have come to realize the significance of filter carts in achieving lubrication excellence. However, it is still a challenge for many facility managers to select the right filter cart. Choosing an incorrect system can prove costly. Here is what you need to consider before purchasing a filter cart:

Intended use

Offline filtration is not the only use of a filter cart, you can flush new components, dispense new oil, and perform routine oil changes. Before you select a cart for your application, take into account factors like weight and size. The filter cart you choose should easily reach each the system you want to clean up. It’s not recommended to buy a system that is too cumbersome to use or too difficult to move to the desired locations.

Filter type

The filter type is another factor you must consider before choosing a specific filter cart. For this, you need to determine the desired ISO cleanliness code you want to achieve. Select a system that has a micron rating as small as the particle size with which you want to filter. Some filter carts use duel elements that run in series. You should also consider the beta rating factor. The higher the beta rating, the more efficient the filter element. The minimum should be at least beta 200 or higher.

Flow rate

When it comes to developing an effective lubrication cleanliness strategy, there is no one-size-fits-all solution. The same applies when it comes to selecting the appropriate pump. Before you make the final decision, identify all the applications you want to use your cart for. Pumps come with varying attributes. For example, a pump ideal for an ISO 680 gear oil will not be a good choice for ISO 32 hydraulic oil.

Sample ports, filter heads, hose end configuration, manual filter bypass, and power source are also important considerations when choosing the right filter cart for your facility. A little research can make a huge impact on your lubrication outcomes. So, evaluate your situation carefully.
