CBD Filter Bags and Botanical Extraction Filters

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.

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.

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.

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.
