The 100 micron Mesh Replacement Small Secret Box is a sifting bag of approximately 30 x 29 cm, created to renew the drum of the compact extractor and obtain a finer separation during extraction.

The Secret Box Small 100 Micron Replacement Mesh allows the filter bag inside the rotating drum to be replaced when the original fabric shows wear, tears, deformation or loss of tension.
The 100 micron opening provides finer sifting than a 200 micron mesh, limiting the passage of plant fragments and favouring the collection of small particles released during rotation.
The approximate 30 x 29 cm size is designed for the compact Secret Box, a mechanical extraction machine with outer dimensions of around 40 x 30 x 27 cm. This accessory can be used as an immediate replacement for a damaged part or as a second unit prepared for sessions involving several loads.
The bag does not include the machine, motor, complete drum or collection tray.
Keeping the fabric clean, correctly installed and free from damage helps maintain consistent filtration, reduces the passage of coarse plant material and allows work to continue without having to replace the entire extractor.
The Secret Box Small 100 Micron Replacement Mesh is a filter bag compatible with the drum of the compact Secret Box version. The part forms the sifting surface where dry plant material is placed before activating the rotating movement of the machine.
During operation, flowers and trimming residues move inside the drum and come into contact with the mesh. Detached trichomes pass through the 100 micron openings and fall onto the tray located at the bottom. Leaves, flowers and larger particles remain inside until the cycle is complete.
The bag has approximate dimensions of 30 x 29 cm. This size corresponds to the small model and should not be confused with the replacement part designed for the Secret Box Big, as the larger version includes a drum with greater dimensions.
The 100 micron mesh provides a finer selection than the 200 micron option. As it has smaller openings, it can retain a greater proportion of plant residues. The final yield will depend on the condition of the flowers, rotation time, selected speed and the amount loaded.
Some references identify this version with a green thread, making it easier to distinguish from other micron sizes. Before fitting the replacement part, it is advisable to check the dimensions and exact compatibility with the available machine.
This replacement part is used to restore drum functionality when the original bag shows wear caused by use. A deformed, loose or perforated mesh can affect separation and allow plant fragments that are too large to fall onto the collection tray.
The Secret Box Small 100 Micron Replacement Mesh can also be used to modify the type of filtration. Compared with a 200 micron mesh, the 100 micron opening creates a finer selection and limits the passage of larger plant particles.
During post-cultivation cannabis processing, the bag can be used with dry flowers and trimming residues that still retain visible trichomes. The method makes it possible to use small resinous leaves and selected fragments that would normally be excluded from the main classification.
The part directly participates in the Dry Extraction process. During rotation, trichomes are separated by mechanical action, pass through the fabric and are deposited on the tray. There is no need to add water, ice or solvents.
It is also practical as a spare unit. Having a second bag ready allows work to continue while the first mesh requires cleaning, inspection or complete drying. This option reduces interruptions during sessions involving several loads of plant material.
Before replacing the bag, the Secret Box must be completely disconnected from the power supply. The drum must remain empty and stationary. It is also advisable to remove the lower tray to prevent accumulated residues from falling during dismantling.
Once installed, the mesh must be used with completely dry plant material. Moisture makes trichome separation more difficult, encourages residues to stick and can create build-up on the fabric.
To facilitate separation, it is common to chill or freeze the selected flowers and residues for around 24 hours beforehand. The material should be kept inside tightly sealed bags to reduce moisture entering and limit condensation.
The load should not fill the entire drum. Although the Secret Box Small can process around 150 grams, enough space should remain for the flowers to move freely. An overly compact load reduces contact with the mesh and may place unnecessary pressure on the seams.
The first run can be carried out at a low speed for a few minutes. This setting produces moderate agitation and allows the performance of the new bag to be checked. Processing time or speed can then be increased, bearing in mind that more intense rotation may increase both the quantity obtained and the passage of small plant particles.
After every session, the contents must be removed and the mesh cleaned while dry. A soft brush can remove attached residues without deforming the fabric. Sharp tools, metal spatulas or sudden movements that could create holes must not be used.
When deeper cleaning is required, the manufacturer’s instructions should be followed. The bag must be completely dry before being fitted again. The machine must never be switched on while moisture remains inside the drum or near electrical connections.
Buying the Secret Box Small 100 Micron Replacement Mesh helps extend the working life of the extractor without replacing the complete machine. When deterioration only affects the filter fabric, fitting a new bag restores normal drum operation.
Before confirming the purchase, it is necessary to check that the machine is the small model. The compact Secret Box has approximate dimensions of 40 x 30 x 27 cm, while the Big version uses a considerably larger drum. Replacement parts for both formats are not interchangeable.
The micron size should also be checked. The 100 micron bag provides finer filtration than the 200 micron version. This difference affects the number of particles that pass through the screen and the selection obtained during each run.
At Hydroponics Blanes, you will find this replacement part along with meshes in other micron sizes, extraction equipment, trays, collection tools and maintenance accessories.
The price of the Secret Box Small 100 Micron Replacement Mesh may vary depending on availability and current promotions. As this is a specific part, it is advisable to check the 30 x 29 cm dimensions and micron size before completing the order.
Replacing only the bag is more economical than changing the complete extractor when the motor, drum and structure continue to operate correctly. Keeping an additional unit also helps prevent waiting times during sessions involving several loads.
