How It Works

How Botanical Extraction Filtration Works

Botanical extraction filtration happens in stages. In the initial extraction, the raw plant material is held in a micron rated filter bag inside an extraction column, centrifuge basket or press while the solvent washes through it. The bag keeps the herb and plant solids out of the extract so the liquid leaves the equipment clean.

After extraction, the liquid is clarified. Micron rated filter bags remove the remaining fines first, then 98% absolute filter cartridges give finer filtration, including clarification after winterizing. Carbon filters remove other unwanted compounds, and larger systems use lenticular filters and filter press panels.

Each stage protects the next one. A good bag stage keeps solids off the finer cartridges and lenticular filters, which extends their life and keeps the whole filtration system running at the right flow rate.

Warning Signs

Signs Your Extraction Filters Need Attention

  • Extraction or filtration flow slows down

  • Fines or haze show up in the extract

  • Pressure keeps rising across a housing

  • Holes, worn seams or a bag that will not seal

  • Cartridges loading faster than normal

Extraction Bags

Filter Bags for the Initial Extraction

AFF manufactures standard and custom filter bags for botanical extraction, including CBD and THC. These bags are typically found in extraction columns, centrifuges, presses and other pieces of equipment that do the initial extraction, where they hold the raw material while the solvent passes through.

We make filter bags for alcohol, CO2 and butane style extraction from a wide range of nylon monofilament fabric, micron rated polyester filtration fabrics and micron rated polypropylene filter fabrics. Nylon mesh gives precise particle retention and strength, and felt bags give high dirt holding capacity for finer filtration.

Custom Bags

Bags for Any OEM or Custom Unit

We can manufacture bags for any OEM extraction equipment on the market, and we make custom bags for custom units. Send us the equipment make and model, or the dimensions of your current bag, and we will build a replacement with the right size, top and seal for your column, centrifuge basket or press.

Because every bag is built to order, you can match the media and micron rating to each step of your process instead of working around a stock size. We also carry other types of liquid filter media for specialty extractions.

Process

Extraction Filtration by Stage

Match the filter to each stage of your process. Coarse filtration protects the finer stages, which keeps cartridges and lenticular filters from loading too fast and helps the final extract stay clear.

Stage Purpose AFF Filters
Initial Extraction Hold raw plant material while solvent passes through Nylon mesh and felt extraction bags
Bag Clarification Remove remaining fines from the extract Micron rated filter bags
Fine Clarification Finer filtration, including after winterizing 98% absolute filter cartridges
Polishing Remove other unwanted compounds Carbon filters
Larger Systems High volume clarification Lenticular filters and filter press panels
Post Extraction

Post Extraction Filtration and Clarification

We supply filters for post extraction filtration, including micron rated filter bags for initial clarification, 98% absolute filter cartridges for finer filtration and clarification after winterizing, and carbon filters to eliminate other unwanted compounds. We also sell lenticular filters, filter press panels and other filters used in larger systems.

AFF also supplies housings for botanical extraction filters, including bag filter housings, cartridge filter housings, lenticular filter housings and filter presses, so the filters and the equipment that holds them come from one source.

Extraction Filter Media and Micron Ratings

Mesh stops particles at the surface for precise retention, and felt traps fines through its full depth. Pick the media and micron rating for each stage, or send us your process and we will recommend them.

Filter Media Filter Type Micron Range Common Use
Nylon Monofilament Mesh Surface 5 to 1,200 Raw material bags, reusable
Polyester Mesh Surface 5 to 1,200 Coarse and medium straining
Polyester Felt Depth 1 to 200 Clarification, high dirt holding
Polypropylene Felt Depth 1 to 200 Clarification, broad chemical compatibility

FAQs

CBD Filter Bag Questions

Send us your extraction method, equipment and micron rating, and we will match the right filter.

CBD filter bags are micron rated bags that separate plant material and solids from the liquid during botanical extraction. They line extraction columns, centrifuges, presses and other extraction equipment, and they are also used after extraction to clarify the oil before finer cartridge or lenticular filtration.

We make extraction filter bags from nylon monofilament mesh, micron rated polyester fabrics and micron rated polypropylene fabrics, including polyester and polypropylene felts. We also carry other liquid filter media for specialty extractions.

The right micron rating depends on your extraction method, the solvent and how clean the liquid needs to be at each stage. Coarser mesh is used to hold back the raw plant material, and finer felt or mesh bags are used for clarification. Our felt media covers 1 to 200 micron and our mesh covers 5 to 1,200 micron. Tell us your process and we will recommend a rating.

Yes. We make filter bags for the raw material in alcohol, CO2 and butane style extraction, and we build them to fit your extraction column, centrifuge basket or press.

Yes. We can manufacture bags for any OEM extraction equipment on the market and make custom bags for custom units. Send us the equipment make and model, or the dimensions of your current bag, and we will build a replacement that fits and seals.

Post extraction filtration usually starts with micron rated filter bags, then moves to 98% absolute filter cartridges for finer filtration, including clarification after winterizing. Carbon filters remove other unwanted compounds, and lenticular filters and filter press panels are used in larger systems.

Nylon monofilament mesh bags are strong and can be cleaned and reused in many applications. Felt bags hold the solids inside the media, so they are normally replaced once they are loaded. Inspect any reusable bag for wear, holes or damaged seams before each run.

Yes. We supply housings for botanical extraction filters, including bag filter housings, cartridge filter housings, lenticular filter housings and filter presses.

Tell us your extraction method and solvent, the equipment make and model or bag dimensions, the filter media and micron rating you use now, and the quantity you need. A sample of your current bag also helps us match it.
