J-Press® Systems In Inventory

Evoqua has many J-Press® filter presses in its inventory - ready to ship.

​Evoqua is proud to offer a range of brand new J-Press® filter presses, each one a genuine JWI™ product, just off the factory floor. These filter presses are ready to ship directly to you.

Stock presses are offered in two sizes, 630 mm and 800 mm. Each size has a range of volumes, described below. Cake thickness from each filter press size is 32 mm, and both the 630 mm and 800 mm filter presses come with gasketed, recessed chamber filter plates.

We also stock a large inventory of parts which allows us to customize a press to your specifications.

If you are trying to best-guess the size of filter press you might need, we have a table using hypothetical numbers for two industries that typically use filter presses. Your numbers will vary depending on your industry and process, however this will provide some context for you.

 other items to consider when specifying a filter press

​When specifying a new press, even when it's off the shelf, don't forget about other ancillary needs.

You'll need to consider waste disposal. For that we have a range of material handling equipment including dumpsters, spatulas and more.

You may need to place or relocate your filter press. We design and build platforms and conveyors for easy waste disposal.

You will need to adjust the flow rate of your slurry. A slurry that flows to fast or too slow can damage the filter press or produce poor dewatering results. For accurate, calibrated slurry throughput we design and build pump skids. J-Press® Systems In Inventory
