75 

 

System 75 is intended for air volumes between 80 and 180 m

3

/hour and available in the following 

mounting versions: 
 

 

Table mounting (BM) 

 

Wall mounting (HM) 

 

Ceiling mounting (HMS) 

 
The different mounting versions have various reaches in the recommended max working position. 
The system 75 extraction arms are available with reaches between 550 mm and 1,990 mm de-
pending on mounting version. 
 
System 75 comes in three different material versions:  
 
 

Aluminium: 

 

Aluminium pipes with joints of polypropylene (PP). 
This version is used in non-aggressive areas such as laboratories, hos-
pitals, schools and the pharmaceutical industry. 

 
 

Chemical resistant:  Pipes and joints of polypropylene (PP). 

 

 

This version is suitable for aggressive areas, e.g. chemical industry.  

 
 

Antistatic: 

Pipes and joints of conductive polypropylene (PP). 
This version is suitable for ESD-areas and the soldering industry and for 
exhaustion in EX-areas. 

 

Cleaning of System 75:

 

Polypropylene (PP) and PETG are not to be exposed to temperatures above 90

°

C and can there-

fore not be sterilized by autoclave. It is recommended to clean the parts in a general detergent or 
another cleaning material. Polypropylene withstands almost all commonly used cleaning materials 
and cleaning spirits. 
 
Hoods: 
The hoods for system 75 are available in two material versions. The majority of hoods are made of 
transparent PETG (Polyethylene Terephthalate, Glycol-modified). In addition, there are three types 
in anodized aluminium: suction pen, suction nozzle and 200 mm hood. The hood is also available 
in a powder-coated version. All PETG hoods are delivered with a loose stub pipe of anodized 
aluminium.  
 
For System 75 Chemical resistant, the hoods are made of white polypropylene (PP). For this ver-
sion, the Ø200 hood is also available in a powder-coated version. Please notice that this hood is 
not as resistant to chemical affect as the PP-hoods. All PP hoods are delivered with a loose stub 
pipe in polypropylene (PP). 
 
For System 75 Antistatic, most of the hoods are made of black conductive Polypropylene (PP). The 
antistatic Ø200 mm metal hood is made of chromated aluminium. The stub pipes are made of con-
ductive polypropylene (PP), and all hoods are delivered with a loose stub pipe. When cleaning the 
hoods, never expose them to temperatures beyond 90

°

C (194

°

F). The hoods withstand all com-

monly used cleaning materials and cleaning spirits.
