Note: XCell® ATF Stainless Steel Housings require a vacuum (negative pressure) to move the
diaphragm to its lowest position. Positive pressure from the bioreactor is insufficient to
completely deflate the diaphragm, necessitating the use of vacuum to ensure proper
XCell® ATF Stainless Steel Housing operation.
