Filter Press

A filter press is a batch operation, fixed volume piece of equipment ranging from .01-600 ft3 that separates liquids and solids using pressure filtration. A slurry is pumped into the filter press and dewatered under pressure. A filter press can be used for process, oils, water and wastewater treatment in a variety of different industries and applications.

A filter press has four main components:

Frame:  The steel frame acts as a clamping device for the filter plates.

Filter Plates:  A filter cake forms in the chambers between filter plates.

Manifold:  Our standard manifold consists of piping and valves which control the slurry inlet and connect the four corner filtrate discharge ports into a common discharge pipe.

Filter Cloth: A cloth filter that is attached to both sides of a filter plate. Solids build up on cloth to form a filter cake, separating liquids from solids.

Custom filter press for polishing up any Oleoresins dissolved in a solvent.

There is no faster or more convenient way to filter your solution than a filter press.  This unit is recommend for up to 25 liters of wax, 50 liters of crude (@50% wax), 500 liters (132 Gallons) of 10:1 Mixture (Solvent/Crude) per batch every +/-2 Hours.

This machine is the critical step missing in your MIPs lab between your initial extraction (Ethanol, CO2, BHO, Blaster) and your Rotary Evaporator.  No more filtering by hand.  No more small Buchner funnels, or filters with silly names.
Whether you have a resin made with CO2, Butane, Propane or other gases, solvents such a Ethanol or others, this unit will work for your oil.

Your oleoresin must be dissolved in a solvent like ethanol, isopropanol, and methanol.  We do not recommend more volatile solvents on this unit such as pentane, or hexane.

Order includes a recessed plate filter press which you can customize the number of filter plates and thus the filtration capacity of the unit. Unit can hold up to one cubic feet (larger units available).  This means you can hold up to 28 liters of filter cake, wax, clay, spent carbon, silica, magsil, etc…
Our press is designed with an air bleed system, so you can clear out all your solution from the press and filtration media so in the end there is no waste from soaked clay or carbon or lots of solution in your pipes and filter press.
This easy to use unit will filter out particles from your solution, such as dirt, leaves, soil, carbon, clay, etc…
After initial filtration, you can use this unit to de-wax your cold solution.  We recommend our filter trolley for de-waxing as the pressure created in this machine will cause some waxes to dissolve.  This can be cleaned up later using clays.
You must have a tank or barrel where your solution is stored, preferably agitated.  The included pump will suck the solution from wherever you are storing it and run it through the filtration plates.

Further clarification and decontamination is achieved by using a silica based medium and lab grade filter papers to produce a tincture that is as clear as possible which has been scrubbed of dirt and debris, mold and bacteria, most color from chlorophyll and other contaminants, heavy metals from fertilizers, and some chemicals from pesticides.

It includes everything needed to get you going (you must supply compressed air and electricity), including consumables, operating instructions and support.

All valves and plumbing are included, and we use cam and grove fittings and sanitary fittings so this unit is easy to disassemble and clean or unplug pipes to move it around.  We know how nasty and sticky oleoresins are so this machine breaks down quickly and completely so you can clean every nook.

The unit can be mounted on casters for added mobility.

Unit includes a diaphragm pump with Teflon diaphragms that are inert to your solution and tough enough to last for months of service.  The diaphragms will work hot or cold, and can take large particles without getting clogged or damaged.
Diaphragm pumps are easy to use and easy to regulate the speed they operate at, are easy to clean and disassemble, and are easy to repair with easy to source replacement parts.  These pumps are powered by air, thus eliminating the risk of an explosion caused by sparks in an electric motor.
This unit uses one simple pump to power the filter press, send solution to heating, centrifuge, and recirculate your tincture as it agitates in the tank while additives work their magic.  Our pump does not have to be primed, so it can suck the solution as well as pump it at high pressures.
The pump with proper hoses, can suck up your solution from another tank and pump it to our reaction vessel, it can also pump the finished solution to your next process or you can connect your Rotovap directly to the reaction vessel.
The additives and consumables we offer are high quality and inexpensive, including carbon and clay.
Benefits of this system:
  • Labor savings.
  • Solvent savings.
  • Time savings.
  • Safe and easy to use.
  • Quick and easy to clean.
  • We stock all consumables at reasonable prices.
  • Multi-function unit.
  • Fast filtering.
  • Made in the USA
  • Can Filter, de-wax, bleach, deodorize, and clarify.
This unit will save you money the day you set it up.  It is easy to install and should be up and running within the hour of being un-boxed.  Every process is easy to set up and you can walk away and leave the process unsupervised (which we don’t recommend).  Labor savings alone pay for this machine.  Because the unit is closed loop, you will not lose much solvent during filtration; costs of lost solvent pile up quickly.
No expensive vacuum pump required.  No lab glassware to break.
Our equipment is manufactured in USA by skilled craftsmen using American made components.
Basic Standard Operating Procedure:
  1. After extraction with solvents, filter out debris.
  2. If working with gas extracted material, dilute in solvent and freeze.  Freeze solution and run through filter for de-waxing.
  3. Degum your solution and remove gums.  (Not with this machine)
  4. Filter with clay.
  5. Filter with carbon.
  6. Filter with silica.
  7. Proceed to Rotovap and SPD, Wiped/Thin Film etc…
Diaphragm Pump Operating Temperatures:


Your pump can be customized to operate on the temperature based on your application.  Below are the diaphragm materials and their recommended operating temperatures.

Buna-N (Nitrile):  10°F to 180°F (-12C to 82C)
Geolast®:  10°F to 180°F (-12C to 82C)
EPDM:  -40°F to 280°F (-40C to 138C)
Santoprene®:  -40°F to 225°F (-40C to 107C)
Viton® (FKM):  -40°F to 350°F (-40C to 177C)
PTFE:  40°F to 220°F (4C to 104C)
Polyethylene:  32°F to 158°F (0C to 70C)
Polypropylene:  32°F to 180°F (0C to 82C)
PVDF:  0°F to 250°F (-18C to 181C)
Nylon:  0°F to 200°F (-18C to 93C)

Temperature limits are solely based upon mechanical stress and certain chemicals will reduce the maximum operating temperature. Consult a chemical resistance guide for chemical compatibility and a more precise safe temperature limit. Always use minimum air pressure when pumping at elevated temperatures.

Manufacturing times vary.  Shipping will be invoiced separately.
