Laboratory Filtration Equipment


EconoClear Membrane Filters

EconoClear Membrane Filters are available in PES (polyethersulfone), PTFE (Polytetrafluoroethylene) and CA (Cellulose Acetate).

PES is an extra high performance membrane formulated and optimised for critical fluid applications. It has an asymmetric pore structure resulting in graded particle retention and therefore has excellent throughput. The flow rate is very fast and the membrane is bubble point tested for quality assurance.

Membrane Specifications

PES = Polyethersulphone, PTFE = Polytetrafluoroethylene, CA = Cellulose Acetate

The PES membrane also shows extremely good resistance to acids and works well in PGM analysis or other mining applications.

Hydrophobic membranes are available for venting and aggressive fluid filtration. They are also very good for gas sensor protection. These show very
good air flow rates resulting in fast response times. The thick non static membrane is easy to handle and seals well between gaskets. This good
sealing together with the very high water resistance protects the valuable electronic components underneath well, even under the most strict SABS
water tests. The thick membrane also has very high mechanical strength, which prevents rupture of the membrane when used in instruments under
harsh conditions such as mine monitors. The PTFE membrane is also not packaged with silicone impregnated spacers between, thus the silicone
free manufacture and packaging provide assurance of no silicone interference with the circuitry.

Five micron Cellulose Acetate membranes are available for condition monitoring and oil analysis. There is also 0.8 micron Cellulose Acetate membranes
which are commonly used for occupational hygiene and nuisance dust monitoring.
