Filter Vats

  • Durable material
  • Extended lifetime
  • Wear-resistant
  • Chemical-resistant
  • Improved sealing in collectors
  • Suitable for a wide range of filter applications


Roxia filtrate vats are important constructional components in big tower press filter plates. Their primary function is to support filter cloth and collect the filtrate and drain it out from the filter. Filter vats need to withstand not only big pressures but also aggressive, wearing substances. This is why Roxia vats are made from wear-resistant, high-density polyethylene (HDPE). Filtrate collectors in connection to the vats have improved design for improved tightness.  Consult the Roxia filter experts to select the most suitable filter vats for your application.


Durable Filter Vats

The Roxia vats have been re-engineered to extend the lifetime not only of the vats themselves but also other filter parts. Vat’s primary functionality is to collect the filtrate in the filtrate collectors and drain it out from the tower press filter. All types of abrasive slurries and filtrates are processed and dewatered inside the filter plates. That is why the plate vats need to be made from durable materials to fight these aggressive conditions.

Roxia filtrate vats and collectors are made from extremely durable, high-density polyethylene (HDPE) which effectively resists any kind of erosion and corrosion. Wear-resistant HDPE enables the vats to last longer which brings immediate savings in spare part costs.

Roxia improved sealing of the filtrate collector. They properly seal the filter chamber and prevent any dripping onto the plate.

Tight Sealing Prevents Plate Corrosion

During the pressing phase the liquid is squeezed out of the filter cake. Filter vats collect all the liquid leading it to filtrate collectors. It is essential for the construction to properly seal in order to prevent other than wetted parts to be affected by the process liquids.

Roxia filter vats:

  • Are made of durable material especially selected for the duty
  • Have improved sealing of the filtrate collector
  • Give longest mileage and lowest operational costs

Roxia filter vats have three different corner types: R220, 210 x 210 and 173 x 173.

Vats Characteristics

Roxia vats can handle a large range or slurries. Typical mineral slurries are copper, zinc, lead, gold and certain substances in chemical and pharmaceutical applications. They all have one thing in common – none of them are easy to handle. Because of that, resistant vat material is required, and it works best only when paired with great engineering as is represented in Roxia filter vats.


Filter vats by Roxia can have three dalternative corner types: R220, 210 x 210 and 173 x 173.

Wear-resistant vat material

Based on years of experience, Roxia vats have been redesigned and more resistant material was chosen. We are using durable, wear-resistant polyethylene also known as HDPE. This polyethylene offers higher density and extends the vat lifetime.

Upon request, Roxia can also provide different high-density polyethylene raw materials. Filter vats made by Roxia can also withstand high slurry temperatures up to 80 °C. All listed properties make Roxia filtrate vats able to withstand the toughest applications.

Roxia vats can handle a large range or slurries.

Filter vat sizes and corner types

Separate filtrate vats are used in large filter plates, sizes 2.5 m² and 6.0 m². The construction of the 1.6 m² filter plate does not have separate vat.

The standard sizes for Roxia filtrate vats are 6.0 m² and 2.5 m². Vats are available in all models, lowest, normal and top vat. You can also choose between different chamber heights, thicknesses and possible corner types. Contact us and consult the best options for your filter.

Possible corner types:

  • Corner type R220
  • Corner type 210 x 210
  • Corner type 173 x 173
