Vacuum and pressure drum filters, YU and PYU

The advantages of the vacuum drum filter YU and pressure drum filter PYU, formerly the Bird Young rotary filter, lie in thin cake applications, where highest filtration rates are combined with high washing rates, highest solids throughput rates, and all this also under gas-tight or pressurized conditions.

The YU / PYU filter is best suited for free-filtering materials, where it can benefit from the much higher filtration rates. Its unique, single-cell design provides for very high filtration capacity (5-10 times higher than conventional drum filters), excellent cake washing due to thinner cakes, and smaller space requirements.
