Flow GPM (B)
(A) Efficiency represents the initial efficiency on a clean element challenged on a single pass through a water base slurry of PT1 fines test dust at 3 GPM. Effieciencies are derived by counting the ratio of upstream versus downstream particles um = micron.
(B) Flow data based on gallons per minute (GPM) for 1 pound (PSID) of pressure across a clean filter.
(C) Dirt load conducted until vessel pressure reached 40 pound (PSID).
Knight Corporation believes laboratory generated performance data is a useful tool for comparing different micron ratings and as a guide for establishing a recommendation in a filtering application. However, this data should not be construed as a guarantee or warranty by Knight Corporation, either expressed or implied, of a specific performance from use of our product. Due to variances in fluid viscosity, temperature, velocity, pressure and contaminant size, shape and texture, Knight Corporation cannot guarantee field results equaling test results.
