Crossflow Tubular Membrane

Graver Technologies' crossflow filtration technology is used in demanding applications where extreme process conditions or difficult feed streams make other separation methods unsuitable. The cross-flow systems have been proven especially effective for high solids or very viscous fluids, or where processing must be done at elevated temperatures and/or pressures, or pH extremes.

Home

RTEC™ G

RTEC G Series filters feature a microfiberglass/phenolic resin construction that produces an extremely rigid pore structure. This construction allows the filter to withstand extremes of viscosity and temperature without compression or collapse. In addition, a true graded density construction allows complete utilization of the filter’s depth, with coarse particles captured in the outer zones and finer particles captured nearer the core.
