NOTE: Up until September 2002, Apeks used a white
disc lter known as the Porvair lter in it’s yoke model
rst stages. While Porvair was an excellent lter for
air, it was determined to not be acceptable for use
with enriched air nitrox (EAN). Since Apeks preferred
all of it’s models to be EAN40 compatible new, out of
the box, the Porvair lter was discontinued. Apek’s
standard conical lter (pn AP1472 as used with the DIN
connection) was substituted. Please note that where
the Porvair lter was loaded into the front of the yoke
connector, the conical lter gets loaded from the back of
the connector. To enhance the cosmetics of a regulator
inlet with a conical lter installed, a new lter guard
(AP1406/1) was designed to install into the front of the
connector. DO NOT mistake the lter guard as a lter. It
is to be used only in conjunction with the conical lter.
Before starting reassembly, perform parts clean-
ing and lubrication in accordance with Procedure
