Closed Column Pressure Extractor
This system allows the user to build up solvent pressure by closing the valve, pulling a vacuum and filling the extractor, Extractor will fill about 85% with solvent before the internal pressure will equal the pressure of the can propellant.
Upgrades:
Pressure Gauge - Allows the User to see vacuum and pressure on the column when operating
Shower Head - Top Cap has a round FNPTshower head on the bottom of it to allow for better dispersion of Solvent
