The ErtelAlsop Cannaskid™ was designed with the ethanol extractor in mind. Our four-stage filtration skid is C1D1 compliant, and can handle cryogenic or room temperature extractions.  Powered by a positive displacement gear pump for optimal flow of 1-15 gpm, each filter stage within the assembly plays an important role in processing your miscella/crude oil prior to evaporation. Take your extract from muddy green to beautiful amber in just four easy steps with the ErtelAlsop 4 Stage Lenticular Cannaskid™.
