Gas streams with high levels of particulate matter can damage downstream monitoring equipment.  Perma Pure’s FB™- Series Inertial Bypass Filters eliminate large amounts of particulate, extending the life and performance of particulate and coalescing filters in CEMS and process monitoring applications.

In high particulate, dusty environments like cement mills or coal-fired power plants, the FB-Series Inertial Bypass Filters can be used to remove large particles of dust and ash from gas samples, preventing them from clogging and damaging the finer porosity filters of analysis equipment.  Cleaner samples produce more accurate measurements and reduce analyzer equipment wear.

The high velocity flow through the filter allows it to self clean for maintenance-free operation.  The FB-Series’ stainless steel construction tolerates very corrosive gas environments, with a range of flow ratings and filter elements available to suit any monitoring application.  For high temperature wet samples, an optional heating system is available to prevent sample loss through condensation.

FB-Series Bypass Filters can also be used to provide “fast loop” readings, reducing analyzer response time and extending life.  In applications where the sampling system and sample point are separated by a significant distance, a pump or vacuum eductor can be used to pull the small 1-2 lpm sample required by the analyzer from the larger sample stream. The bypass sample is cleaned in the FB-Series filter and sent quickly to the analyzer for a fast, accurate reading.
