Air supply into the first stage is protected by a cone-shaped sin-
tered filter (30K) which retains all impurities from the cylinder and
the valves.
The first stage is connected to the cylinder valves by means of an
international YOKE CGA 850 connection using a newly designed
advanced engineering concept bracket (31), or by means of a
DIN UNI EN 12209-1-2-3 (21K o 22K) threaded connection in
compliance with UNI EN 250:2000 standards. DIN connections
are recommended when cylinders with more than 200 bar (2900
psi) working pressure are used.
In addition to these advancements, the balanced piston 1
stage has been aesthetically improved with finishing details and
a high-tech design. Its outstanding technically advanced con-
struction and simple mechanics insure superior performance
and ease of service for years.
1.4 - AC2 In-Line Piston 1
Small, lightweight, simple, durable construction and easy main-
tenance; these are the features of this In-Line Piston 1st stage
that offers remarkably high performance compared to a bal-
anced piston model.
Its compact and attractive design features 4 low-pressure 3/8"
ports, arranged in pairs, with preset angles to allow for easy con-
nection with accessory equipment. Intermediate pressure set-
ting is easily performed by externally adjusting a unique revolving
nut.
Inside, a cone shaped high capacity filter provides a filtering
capacity 200% higher than a standard flat filter.
Airflow capacity reaches up to 2,100 liter/minute due to new
larger air ports, offering unequalled performance in this catego-
ry of regulators.

International (200÷300 bar) (2900÷4350 psi) DIN connections
are interchangeable and easily replaced in a few minutes.
Satin finish offers maximum surface protection, while contribut-
ing to the outstanding strength and reliability. The first stage is
manufactured with the finest materials and quality Cressi-sub
workmanship.
