With the ProClean Conveyor (PCC) HECHT developed an extremely flexible and reliable conveying system. The special design with its innovative filter head comes with numerous further advantages.
Top level information
The first thing that comes into one’s mind when talking about the HECHT Pro Clean Conveyor is its innovative filtering system. The filter is really the heart and at the same time the essential distinctive feature of each vacuum conveyor.
In the case of the ProClean Conveyor (PCC) 100-300 models, a powerful ring filter is used.
The filter unit rests on the tubular separator like a head. Due to its cylindrical shape, the filter features a large surface and thus causes only little air resistance while at the same time requiring only little space. The filter is very easy, safe and fast to change – it can be wetted before the technician opens the lid.
Especially for the connection of machinery like blenders or filling stations with high production volumes, HECHT developed the ProClean Conveyor PCC 700, a further development of the HECHT vacuum conveyor for systems with high GMP- and FDA-requirements of our customers.
The PCC 700 enables a secure conveying of bulk solids, guarantees a dust- and contamination free environment and is extremely flexible to use. Its special design with the innovative filter concept offer numerous advantages.
It's all about the filter

- Adjustable settings: from fast flight conveying to gentle plug conveying
The PCC 700
From an application side as e.g. a Big Bag discharging station, the product goes via hoses and the product inlet valve into the separator vessel and fills it.
Then, the product gas mixture is separated in the filter units.
When the PCC 700 is fully filled, the suctions-cycle stops and the product outlet valve opens. Now the product is going to be discharged into the different onside applications.
The reasons for the powerful performance of the PCC 700 series are mainly the four huge filter units and the big volume of the separator vessel.
Due to the suction of the product via vacuum and the alternate sequence of filter cleaning (two are cleaned and two are used for conveying), it is possible to convey the bulk solid over long distances and heights.
Because of that, the complete volume of the separator vessel can be filled with only one suction cycle.
A supporting fact is the impressing filter-area (up to 3,6 m2) and through that less filter stress for less pressure difference.
So a more effective transport of very fine grained products (< 1μm) can be achieved. The low filter stress has also a very positive effect on the life time of the filter units.
If there is a filter change, the change can be done within a few minutes very quick and completely by hand without any tools.
Important to know: The PCC 700 series are no pressure vessels and so the have not to be checked separately. They are working with a pressure of maximum 0,49 bar as a standard.
