FullMelt Filtration Bubble Hash Bags – Sets


**Buckets sold separately**


The Filtration Mesh

  • Each mesh variation is defined by its Micron (µm) opening size.
  • This is an indication of the open area of the mesh and is measured micrometers or µm.
  • The 38µm filtration meshes have been woven into a plain Dutch weave.
  • The 250µm filtration mesh have been woven into a plain weave pattern and have been secured in place using heat.
  • Each micron screen has a porosity value greater than 30% insuring that the rate of filtration is fast.
  • With the 38µm filtration mesh bags having an 80mm extension up the side wall of each bag, increasing the filtration surface area of these bags by a factor of two.
  • The mesh is woven using a nylon 6,6 23µm diameter thread.
  • Each mesh is 30cm in diameter and has been secured to the base of the bags with two double lines of stitching.

The Side Walls

  • The sidewalls are a 115 GSM, 100% polyester.
  • Woven into a Poly Oxford pattern.
  • Polyurethane coating on both sides of the sidewalls. This ensures a water and oil proof finish.
  • Each rim of the bags (top and bottom) has been reinforced with a line of web tape.

The Design

  • Handmade and locally produced in South Africa.
  • Each bag is slightly conical in shape.
  • Easy to secure over the rim of a 20ℓ or 25ℓ bucket.
  • The volume of each bag is 39ℓ.
  • There is a 30cm diameter mesh base that tapers up to 40cm open rim.
  • The 25µm & 70µm Filtration bags mesh has been extended by 80mm up the side wall of each bag increasing the filtration area by a factor of two on each of the lower Filtration bags.
  • Each bag in the set is colour coded with the specific micron (µm) size of the bags’ screen.
  • Each bag has two handles.


  • Each micron screen variation has a porosity value greater than 30%.
  • Micron opening Sizes (MOS) are secured through weave patterns and,
  • Mesh weave is heat-sealed to further ensure MOS is secured.
  • Large mesh surface area.
  • Two lines of double reinforced stitching secure mesh to the sidewall.
  • Temperature and pH resistant filtration mesh and sidewall fabric.
  • Sidewall fabric coated in PU.
  • Handmade and locally produced in South Africa with materials sourced from internationally recognized leaders in the mining and chemical filtration industry.
  • 80mm extension on the lower 4 micron filtration bags increases the filtration area by a factor of two.


  • The filtration mesh is sourced from Switzerland from the global leader in mining and chemical filtration mesh manufacture.
  • The design and manufacture of each filtration bag has been graded to international standards for mining filtration applications.
  • Increased rate of filtration due to 30%+ porosity value on each filtration mesh.
  • Filtration mesh surface area over is 700 square center meters (cm²) or 30cm diameter.
  • The lower two micron filtration bags have an increased rate of filtration due to the 80mm extension up the side wall of each bag.
  • Secured weave pattern limits morphing potential of Micron Open Size (MOS) of each mesh under the pressure/weight of filtration.
  • Mesh weave is heat sealed to ensure specific Micron Opening Size (MOS) is maintained over repeated use.
  • PU coating ensures water and oil proof finish on both sides of the filtration bags sidewall fabric.
  • PVC and laminate free.
  • Light and durable sidewall fabric.
  • Easily secured over the rim of a 20ℓ or 25ℓ bucket due to 40 cm diameter rim.
  • Easy access to particulate collected in the filtration mesh.
  • Handles for easy maneuvering of the filtration bags during the filtration process.
  • Quality assurance specification based on industrial standards laid out by the Mining and chemical filtration industries.
