Easy mounting of the vacuum cleaner without needing to make any changes to the original CNC machinery design.
It allows positioning and lowering of the hose exactly in the center of the router, without the need of any external support. Also, the movement and curvature of the hose are minimized so that the air flow loss is reduced, allowing for a more efficient chip extraction.
For machine manufacturers: as the hose is coming from the top, it is not additionally necessary to calculate the weight and size of the moving bridge (gantry) of the machine. This is also a money-saving issue in the construction of the CNC router itself.
During the development of the CNC machine, the construction engineers do not need to design any special hose connectors.
The lifting device is used for emptying the 100 Lt (iV2 model) or the 160 Lt (iV3 model) chip container with the use of a forklift. The operators do not have to make any effort for the emptying process. At the sides of the collecting containers there are two hooks for the lifting kit to be connected to, which in turn is lifted from the truck by a chain.
Strongly recommended whenever possible, the pre-filter is positioned between the vacuum and the chip-generating machine, as the first point of collection of the collected material. It is specially used to preserve the life of the filter inside the vacuum unit. It retains most of the collected material and can have a cone or cylindric shape and serves as a mechanical filter. Through a tangential entry the collected material is centrifuged into its interior until its speed gradually decreases and the material gradually falls to the bottom of the collecting unit due to the force of gravity. Such a process ensures that only a relatively low percentage of collected dust or chips manages to actually reach the real filter positioned in the upper part of the vacuum cleaner.
The cyclonic pre-filter can be combined with a: • 160 L tank • 500 L tank • 1000 L tank
The cyclonic pre-filter becomes almost mandatory for fine or very fine powders, which are very likely to clog the filter quickly, compromising the smooth operation of the entire system, but are only recommended for large, heavy chips. The main advantage of the cyclonic pre-filter is to protect the filter of the vacuum cleaner from quickly clogging, thus extending its life before replacement and significantly reducing the maintenance of the entire system.
HEPA is the acronym used for the definition “High Efficiency Particulate Air”.
It ‘a kind of filter for vacuum cleaner with a particular system of filtering with high efficiency for fluid, liquid or gas. It has the ability to trap a very high amount of particles of very small size, ability that other filters for vacuum cleaners do not have. Indeed, there are different categories of filters (L / M / H), and different categories of HEPA filters, that has made according to the material more efficient to inhale.
The HEPA filter is composed from microfiber filter sheets (generally borosilicate) assembled in multiple layers, and separated by aluminum septa. The microfiber filter sheets have the task to block the polluting solid particles (or particulate). The solid particles are very small and can be harmful to health or may affect the quality of the final product to be obtained.
HEPA filters are part of the category of the “absolute filters”, justified by the fact that these filters have a high efficiency of filterign. In particular, HEPA filters introduce an efficiency of filtering between 85% (H10) and 99.995% (H14). The filtration efficiency of particles of 0.3 µm, is regulated by the UNI EN 1822.
The classification filters for vacuum cleaner and powders emissions into the environment, is assigned by the type of powders and the degree of danger to health. For its suction devices such classification is regulated by IEC 60335-2-69 worldwide. This classification provides several categories of powders, such as:
• Category of powders L (low/moderate): fall into that category powders with MPC values (maximum permitted concentration in the work place) > 1 mg / m³Are retained at least 99% of particles aspirated.The disposal of the collected material must be made trying to raise a few powders. • Category of powders M (medium): fall into that category powders with MPC values (maximum permitted concentration in the work place) > 0.1 mg / m³ and wood powdersAre retained at least 99.9% of particles aspirated.The disposal of the collected material must be made trying to raise a few powders. • Category of powders H (high): fall into that category powders with MPC values (maximum permitted concentration in the work place) < 0.1 mg / m³, with carcinogenic and pathogenic powdersAre held at least 99.995% of particles aspirated.The disposal of the collected material must be done without raising powders.On each iVision vacuum cleaner is applied a label indicating the hazard class of the dust in the environment allowed.
