Replace Bag Filters with the Russell Filtration Solutions

Switching from bag filters to Russell filtration equipment reduces costs and safeguards operators safety

Installing bag filters into your production process offers a simple solution for removing oversized contamination from your liquid products. However, whilst the initial purchase price may be somewhat lower than other filtration methods, such as self cleaning strainers, the long term costs associated with this type of filter detract from the initial cost saving. Such costs include the need to continually change filter bags which in itself is an additional expenditure but furthermore production needs to be stopped when the bags need to be changed which could impact further on company profits. In addition, disposing of the used filter bags impacts upon the environment and can be costly and detrimental to the company’s CSR.

A company who processes polystyrene for the production of foam products, such as cups and refrigerator linings, had bag filters installed within their production line and experienced these problems. In addition, the polystyrene jelly like pellets were able to extrude through the filter bags allowing contamination to pass through. To ensure this did not happen filter bags were changed more frequently. This posed even more issues as the product was hazardous meaning operators exposure and handling of the hazardous product was increased.

Disappointed with the performance of the bag filters the company decided to replace them and turned to Russell Finex after finding them on the Internet. Russell Finex listened to the problems they were experiencing and set up a trial for the Self-Cleaning Russell Eco Filter®. The trial was successful and the strainer removed all their previous problems. The strainer achieved a higher throughput rate than the bag filter and also removed all the contamination from their final product.

Due to the hazardous nature of the product, customizations were made to this equipment which would provide complete peace of mind that there would be absolutely no chance of product leakage that could harm operators’ health and safety. The first customization was the bolting of the strainer, which would usually be supplied with flanges and band clamps. In addition, double mechanical seals were also supplied instead of lip seals.
