Spiral - Model SWT 850-DPX -Solids Concentrating Automatic Filter

The SWT850 is the latest and most popular model in our 800 Series automatic self-cleaning filters. Designed to remove suspended solids (TSS) from high and variable total solids fluid streams, each filter unit contains a motor-driven, rotating spiral-shaped mechanical cleaning device that continuously cleans collected debris from inside the filter element. Solids are collected at the bottom of the filter housing to be expelled through an automatic purge valve or a continuous concentrate stream.

Unlike backwash filters, the SWT system does not require high pressure; it operates at system pressure of less than 20 psi and performs at very low differential pressure. No backwash, cross flow or booster pumps are required. The purge chamber can be configured to dump solids directly to waste or for removal and concentration of solids.

The latest evolution of our Series 800 filters, the SWT850 is designed to remove high total suspended solids (TSS) and reduces the rated flow by up to 50%.

The filters are available in single (SWT850-OEM) or multiple (SWT850-DPX) filter configurations to satisfy higher customer application flow rates.
