SAMPLE EXHAUSTION WITH CYCLONE SEPARATORS AND FOR GRINDING LARGE QUANTITIES

FRITSCH Cyclone separators ensure with their powerful airflow simple feeding and faster throughput. The powerful airflow enables the use of finer sieve rings to achieve a higher final fineness. The cyclones are ideal for even for temperature-sensitive samples and materials which are otherwise difficult to grind finely, such as electrostatically-charged plastics or powder coatings. Two models are available: High performance Cyclone separator and small volume Cyclone separator.

high-performance Cyclone separator made of stainless steel 304, foodGrade, incl. sample glass 1 litre

High-performance Cyclone separator made of stainless steel 304 for sample exhaustion, incl. sample glass 1000 ml and connections for exhaust system.
The compact FRITSCH high-performance Cyclone separator, which is made completely out of stainless steel 304, is particularly indispensable in the analytical sector and the food and pharmaceutical industries. Due to its high surface quality, it offers enhanced resistance to corrosive media such as alkalis and acids, but particularly to media containing chlorides – and is especially easy to clean with a wide range of possible cleaning agents, without leaving any residues. The Cyclone separator can also be fully dismantled, meaning that it can be completely emptied, flooded and sterilised. Your advantage: reliable protection against cross-contamination.

Furthermore a sample vessel 32 ml with lid, article-number 83.3190.16, is available, which can be inserted in the sample bottles 250 ml and 500 ml for dividing smallest sample quantities.
The sample glass is recommended for sample exhaustion with the small volume Cyclone separator for sample discharges smaller than 500 ml, since only a 500 ml sample glass is included in the delivery of the small volume performance Cyclone separator.

With the switch box, both the control of the exhaust system for sample exhaustion with Cyclone separators and for cooling the PULVERISETTE 14 premium line can be done directly via the Variable Speed Rotor Mill PULVERISETTE 14 premium line - fast, simple and comfortable.
The switch box can be used for 100-240 V/1~, 50-60 Hz and up to 3600 Watt.


connecting piece for exhaust system
No. 14.4214.00

Connecting piece for exhaust system, for connection to exhaust system (Order No. 43.9070.00) for additional cooling of the Variable Speed Rotor Mill PULVERISETTE 14 premium line.


dust exhaust system, dust category „M” according to DIN EN 60335-2-69
No. 43.9070.00
Exhaust system, dust category "M" according to DIN EN 60335-2-69

The exhaust system, dust category "M" according to DIN EN 60335-2-69 for 230 V/1~, 50/60 Hz, 1600 Watt is versatile:


For combination with the high performance and small volume cyclones.
To operate the FRITSCH Cyclones you need an exhaust system. The strong airflow ensures simple feeding, increases throughput, and reduces the thermal load of the samples. The high performance and small volume Cyclone separator can be combined with Universal Cutting Mills PULVERISETTE 19, the Variable Speed Rotor Mill PULVERISETTE 14 premium line and classic line. The small volume cyclone can also be combined with the Variable Speed Rotor Mill PULVERISETE 14 premium line and classic line even for passive utilisation – without sample exhaust.
The high-performance cyclone is ideal for combination with the Universal Cutting Mills PULVERISETTE 19 large, the Cross Beater Mill PULVERISETTE 16 and the Disk Mill PULVERISETTE 13 premium line for optimal sample extraction and for comminution of larger quantities.


For cooling of the Variable Speed Rotor Mill PULVERISETTE 14 premium line
By connecting the exhaust system with the connecting piece order no. 14.4214.00, the cooling of the mill can easily be enhanced.


For connecting to Disk Mill PULVERISETTE 13 premium line
The exhaust is simply connected to the PULVERISETTE 13 premium line and operated via a start and stop button on the instrument – for dust free comminution.


For connecting to the Jaw Crusher PULVERISETTE 1, Modell I + II classic line
Simply connect the exhaust system to the integrated connection of the PULVERISETTE 1. Fine dust arising during comminution is automatically removed. The exhaust system is also very useful when cleaning the grinding parts.


For connecting to the Disk Mill PULVERISETTE 13 classic line
The exhaust system can be easily connected to the PULVERISETTE 13 classic line. Fine dust arising during comminution is automatically removed. The exhaust system is also very useful when cleaning the grinding parts.


For exhaustion of the sample during dry measurement with the Laser Particle Sizers ANALYSETTE 22 NeXT
An exhaust system is necessary to ensure automatic sample exhaustion during dry measurement. When the measurement is completed it can also be easily used to manually clean the feeder.


Please note that the exhaust system article no. 43.9070.00, is not equipped with a fine filter and therefore dust may escape. Please consider the valid occupational health and safety regulations. This exhaust system is mostly recommended for dust-free grinding and the vacuuming of during the process developing fine dust in the upper part of the grinding chamber and for the cleaning of the grinding parts.


For vacuuming of the sample during dry measurement with the Laser Particle Sizers ANALYSETTE 22 NeXT, we recommended we recommend the exhaust system article no. 43.9060.00, which is equipped with a hose and an ultra-fine filter of dust class "H" according to DIN EN 60335-2-69, so that the escape of fine dust is reduced.


fleece filter bag for exhaust system (pack = 5 pieces) for exhaust system 43.9070.00
No. 43.9055.00

1 pack = 5 pieces
One pack is included in the scope of delivery of the exhaust system (article No. 43.9070.00).
