Frequently Asked Questions

What is the difference between chamber and membrane filter press?

Chamber filter presses use pressure to dewater sludge, while membrane presses add a secondary air or water compression stage to further reduce cake moisture content.

Can you provide automation integration?

Yes, all our automatic models include PLC control systems with options for SCADA integration, remote monitoring, and predictive maintenance.

What materials are used in your filter plates?

We offer polypropylene (PP), cast iron, and stainless steel plates depending on chemical compatibility, temperature, and pressure requirements.

Do you offer on-site installation support?

Yes, our engineers can provide on-site supervision, commissioning, and operator training upon request.
