KZ03 - Pressure Regulator with Air Filter (Airset) 1
1 : Description
The Type KZ03 pressure regulator with air lter lters the supply air and regulates
the output pressure for various pneumatic equipment.
KZ03-1 140 kPa (image with optional gauge) KZ03-2 for Variable output (Max. 400 kPa)
KZ03-3 for Variable output (Max. 700 kPa)
~Note The number “7” is stamped
with permanent ink on the body
of KZ03-3 to tell apart from
KZ03-2
2 : Operational Principal (Refer to the illustrations on page 2)
The air supply from the primary air intake goes through the lter (15), ltrating
foreign materials. The air keeps owing to the secondary air side until the secondary
pressure balances o with the set spring (15) and shuts o the poppet valve [7]. If the
secondary pressure goes up higher than the set pressure, the diaphragm [6] will rise,
let the extra air escape through the gap between the poppet and the seat ring to the
bleeding hole.

4 : Standard Specications
The Pressure Regulators with Air Filter control the air pressure so each point of use
o the air line is supplied with constant air pressure.
