NOTE
: Up until September 2002, Apeks used a white
disc filter known as the Porvair filter in it’s yoke model
first stages. While Porvair was an excellent filter 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 filter was discontinued. Apek’s
standard conical filter (pn AP1472 as used with the DIN
connection) was substituted. Please note that where
the Porvair filter was loaded into the front of the yoke
connector, the conical filter gets loaded from the back of
the connector. To enhance the cosmetics of a regulator
inlet with a conical filter installed, a new filter guard
(AP1406/1) was designed to install into the front of the
connector. DO NOT mistake the filter guard as a filter. It
is to be used only in conjunction with the conical filter.
Before starting reassembly, perform parts clean-
ing and lubrication in accordance with
Procedure
