Inquiry (采购产品): Filter element To Whom It May Concern: I would like to get a quote for a sintered PTFE cylinder which will be used for an air filter element. I would like to get quotes on 20 and 100 micron pore size if possible. If the 20 is too small, what is the smallest that you offer in PTFE? I can send dimensions once contact has been made. Thanks for your time. **** Hidden Message ***** Jake Rodrigue 70072 Company: CheckPoint Process Pumps & Systems E-mail: jrodrigue@checkpointpumps.com **** Hidden Message ***** jrodrigue@checkpointpumps.com
