ErtelAlsop Filtration

FILTRATION EXPERTS

ErtelAlsop is an innovator in the manufacturing of depth filter media and machinery for liquid filtration since the 1920’s, and is your one source for all cannabis and hemp extract filtration  and liquid processing needs. 

In the production of stable cannabinoid products filtration is an essential step.

ErtelAlsop has a variety of filtration equipment for your cannabis and hemp filtration requirements, including the original 4-stage lenticular filtration skid  and recessed chamber filter presses  for your high throughput Dewaxing needs.

The use of depth filter sheets for the clarificat ion Cannabis and CBD extracts has many advantages compared to the use of filter paper and Buchner Funnels. Due to the depth (thickness) of the filter sheets, and the matrix of cellulose and impregnated diatomaceous earth, the ability to hold particulate back is increased compared to the same filtration volume of filter paper and single layer cloths. 

Additionally, when impregnated with activated carbon, ErtelAlsop depth filter sheets are the ideal choice for the removal of chlorophyll and other odor and color influencing substances. Carbon scrubbing with ErtelAlsop’s MicroClear filter media with immobilized activated carbon is much more efficient compared to loose carbon powder. With MicroClear filter media, your extract has forced contact with activated carbon therefore, shorter contact time can be applied and also less carbon is needed.

That’s why reliable cannabis extract producers of medical-grade marijuana and CBD oil turn to ErtelAlsop precision equipment to achieve excellence in every aspect of the liquid product, from distillation, taste and smell to the right appearance. The use of ErtelAlsop depth filters sheets and lenticular filters quickly and efficiently clarify and decolor your extracts at flow rates from 1 - 50 gallons per minute.

As with all ErtelAlsop filter presses  and lenticular filters, ErtelAlsop filter media is available for any application and/or operating condition, and is chosen based on your specific operating conditions. ErtelAlsop offers the widest varieties of filter media and construction techniques to provide good particle retention, clear filtrate, high flow rates, and dry filter cakes.

The right combination of proper techniques and the proper tools are the difference between a clear, amber extract, and a muddy, undesirable product that contains plant particles, debris, and unwanted lipids.

From research and development applications in the laboratory, to full production runs, ErtelAlsop’s food and pharmaceutical grade depth filters and equipment are staples for producers looking for a professional result.
