Maximum precision in labdevelopmentFilter system design often begins at the Purolator laboratories, where the results of small-scale runs are analyzed.The next step is a pilot-scale filter test at your site to ensure compatibility with actual process conditions.

Run the calculationFrom basic to detailed engineering, the filter system will be designed to reach your process expectations.

Meet the needs completelyOnce final operating conditions are determined, the full-scale production of the final system is shipped and installed. Then we audit and optimize the performance on the line.

Tailor-madesolutionsfor unsurpassed performance

Detailed inspection of the filter.

Engineering and R&D capabilities.

Co-development is the key to our success.
