The pressure differential at the
inlet and the outlet of compressed
air equipment can be viewed at a
glance on the differential pressure
gauge. It is ideal for the mainte-
nance control of filters.
Compact and lightweight
Can be installed easily by merely
providing a bypass circuit.
Provided with a protective cover to
prevent hazards.

1. This product cannot be used in a
location where pulsations could
occur frequently.
Caution
Design Mounting
1. Mounting
1) The HIGH and LOW marks on the back of the
differential pressure gauge indicate the high
pressure and low pressure sides respectively.
Connect the HIGH side to the inlet side of the
filter or other devices and the LOW side to their
outlet side. Do not use a stop valve to prevent
damage to the differential pressure gauge if the
valve is inadvertently left open or closed.
2) Install the differential pressure gauge vertically.
3) The piping of the differential pressure gauge
must be connected securely because it will
break if it becomes detached.
