It is the go to choice for suctioning of materials with a bulk density up to 0,5-0,6 kg/l.
The design is very simple, focused on performance efficiency.
Thanks to air inlets placed on the top, additional air can be conveyed within the suction hose, increasing the material flow fluidification.
Depending on how the hose is positioned over the eyelet, it is possible to adjust the additional air flow.
Coaxial lances are indicated for materials with a bulk density from 0,8-1,0 kg/l or above, such as masterbatches or additives.
Thanks to the design, realized by utilizing two coaxial pipes, compared to the standard version it is capable of suctioning a larger and always constant air quantity; additional air is collected from the upper part of the pipe and then conveyed towards the tip (bottom part), where it mixes with the material.
Unlike the single lance, additional air flow is channelled directly where the material is aspirated, drastically reducing the risk of clogging.
By untightening the ergonomic knob, the external coaxial pipe can slide, increasing or reducing the flow of additional air.
