Flow rate and rejection rate for the ESPA4-4040 and the ESPA4-7 are based on test conditions using pressure of 100 psi. For all other elements on this page, the flow rate and rejection rate are based on test conditions using pressure of 150 psi.

Membranes are normally packaged with a preservative solution comprised of sodium bi-sulfite (SBS) and propylene glycol (PG). However, you may also order them with SBS only.
