IN CASE OF WATER/OIL INTRUSION IN WORK 

 

  Oil, water or chippings may intrude in works 
  because of the previous process.   

The tester may draw in unwanted objects 

  during the exhausting process, and may cause 
possible break down. 
Install the external exhaust unit (optional) within 
the testing air circuit.     
While the FE-20 optional external exhaust unit 
is in use, close the exhaust port of the air leak tester   
with the attached plug.

COMPRESSED AIR SOURCE: 
Water and oil intrusion often cause the pressure sensor in the air leak tester to malfunction.  Be 
sure to provide an air filter, and if necessary, equip an air purifier such as an air dryer.  
Furthermore, it is important to contrive a bypass air piping system when using lubricator so that 
lubricating oil will not intrude the tester 

CLAMPING EQUIPMENT 
Regulators to adjust the cylinder driving pressure must be provided separately 
for each cylinder.  This minimizes the possibility of cylinder movement, which 
destabilizes the pressure supply to the air leak tester.  Supplied air pressure 
fluctuation may interfere with the clamping powers of the other cylinders

KEEPING THE INTERNAL VOLUME AS SMALL AS 
POSSIBLE 
In order to increase test sensitivity, keep the internal volume of 
the work and master parts as small as possible.  Shortening 
pipes or using a core is ways to decrease internal capacity. 

AVOID TEMPERATURE CHANGE
In order to avoid temperature 
interference to work parts waiting to 
be tested, keep them close to leak 
tester and at about the same level. 

PREPARE THE MASTER PARTS 
It is recommended to use master (criterion) parts for air leak testing.    Leak testing accuracy will change according 
to the status of the applied master parts, so it would be ideal to use master parts equivalent to the work parts in 
shape, material, piping and mounting.    Maintaining these conditions can be difficult in actual settings. Please 
refer to the following chart when choosing a master part.
