Directly after harvesting the cannabis buds will be put in Canna-trays® (A), which are then stacked on a Ventilation-pallet (B). The Ventilation-pallets with Canna-trays will be provided with HEPA filters (C) on top and bottom, all together it is called a ‘Sandwich-unit’(D). After the canna-trays are placed on the ventilation-pallet, all internal transport happens with a forklift truck.






After harvesting the buds are placed in Canna-trays, the buds will stay in the Canna-trays during the drying and curing process.

Canna-trays are made of ABS (acrylonitrile-butadiene-styrene) Food Safe Thermoplastic, this is perfect material for your consumable products. ABS thermoplastic is resistant against chemicals like thinned acid, alkaline, oils, fat and aliphatic hydrocarbons.

The Canna-trays are divided into six smaller compartments, this makes sure the cannabis will not slide around and no empty spots will emerge. On the bottom of the Canna-trays you find little holes, these holes make it possible for air to be sucked through.

The Canna-trays are made of 100% recyclable material.

The Canna-trays are easily stacked on each other with a simple clicking system

Size of the Canna-trays: 600x400x60 mm (23.5×15.5×2.4″)

Maximum service temperature: 77°C (171°F).


At the top and bottom of the Sandwich-unit you will find High-Efficiency Particulate Air (HEPA) filters. The function of the filters is to filter out fungi and bacteria, this makes sure your cannabis will always pass the microbial test standards.

The HEPA-filters on top of the Sandwich-unit make sure that all air that enters the cannabis is free from fungi and bacteria. On top of the HEPA-filter you will find a filter pad for protection.

The HEPA-filters on the bottom of the Sandwich-unit catch all the bacteria and fungi that are extracted from the cannabis. On top of this filter lays another filter pad that collects all the kief that is coming free from the cannabis. The filters pads are easily removable, so the kief can be taken elsewhere.

The frame of the filter is made of aluminum while the filter itself is made of high efficiency micro glass fiber paper. HEPA-filters have the lowest possible air resistance, which helps to lower the energy costs


HEPA-filters are used in multiple cleanroom applications like, operating theaters, the pharmaceutical industry and micro-electronics.

HEPA-filters guarantee constant performances and make sure that the cannabis stays in a clean room environment during all stages of the process.


The Ventilation-pallet is made of stainless steel and is assembled in such a way that the whole pallet is easily cleaned.

The front of the pallet has 2 entries, so it can be easily transported by a forklift, no extra actions are required.

The Ventilation-pallets contain 64 to 144 Canna-trays.

Size Ventilation-pallet (without Canna-trays): 1600x 1220x 240 mm (65 x 48 x 9.5 ″) . Weight: 110 kg (240 lbs.)

The Ventilation-pallet is perfect for efficient internal transport. Once the Ventilation-pallets are stacked with canna-trays, all internaltransport can be done by a forklift
