Pressure Filter

ALSI Indexing Pressure Filter

The ALSI Pressure Filter offers a high-performance, yet simple liquid filtration solution engineered with unique features. Our innovative design ensures the efficient removal of fine particles with minimal operator intervention and allows the system to process a higher flow rate per square foot of filter area than comparable gravity filters. Our design eliminates the need for complex components like carrier belts, pulleys, and mobile filter chambers, resulting in a more robust system over competing technologies.

Automatic Filter Cycle

Fully automated filtration through dry cake discharge, eliminating the need for manual operation

Cost-Effective

Cost-effective option for filtration of non-hazardous applications

Media Rewind

Reduce OPEX with optional filter media rewind system
