7.1.5. Permeation rate measurement
NOTICE
The device is subjected to operating pressure and electrical voltage
While performing maintenance works, the device is subjected to operating pressure and electrical
voltage
•
The following preconditions must be established before the measurement for measurement of the permeation rate – as the
condition assessment of the membranes themselves.
•
A cquisition of a suitable volume flow meter with a range of 0.4 – 4 cfm (atmospheric) with hose connection (approx. 40
inch)/plug connection with connection thread G1/4 (BSPP - British Standard Pipe Parallel)

After the measurement, the connection in the head of the membrane and dryer must be closed again by using the blind
plug, the purge air output at the sieve must be cleared. The device must be returned to normal mode "6.3.3. Service mode"
on page 27.
