Alien Air Force
Inline Regulator (high pressure):
Clockwise (In or Down) lowers the air pressure
Counterclockwise out or up increases the air pressure
Notable is how few parts there are on
the ‘new for ’09’ Inline Regulator.
Cap, Base, Piston and Adjuster, plus
Bellville washer springs.
The regulator top holds a single Bellville
washer spring, the larger disk. This
spring needs to have the dome facing
the Piston. On the piston stem are six
more spring disks.
The base holds the high-pressure air inlet
(the adjuster) a ball bearing, a setscrew and
a stainless steel disk. Raising and lowering
the adjuster changes the pressure. A
setscrew and a ball bearing move the
adjuster. Below the ball bearing a stainless
steel disk reduces wear. At the top of the
base is a 012 O-Ring that seals on the
Piston stem.
In the unlikely event air leaks out the setscrew hole in the base,
the adjuster can be removed and the two 010 O-Rings can be
replaced, by first removing the setscrew and then pushing up the
ball bearing and adjuster. The adjuster is threaded inside to allow
the screw that holds the trigger frame and body together to be
screwed into the adjuster, so that the adjuster can be pulled out of
the base. Do not allow the ball bearing or the disk to fall out of the
base. However the adjuster and O-Rings move so little that
deterioration over its useful life is so minimal that servicing the
adjusting should be unnecessary.
Servicing of the inline regulator should be limited to annual or semi annual
lubricating of the O-Ring on the piston and the O-Ring at the top of the base. The
seal is easily removed and can be replaced. Replacing the seal, the two O-Rings
on the adjuster, the O-Ring on the piston and the O-Ring in the base, completely
rebuilds the ‘Alien Air Force’ Inline Regulator.
