Recommended check valve
AKH04B-M5
Compatible with an
atmospheric release
pressure circuit
Possible to make it an atmospheric
release type by installing a check valve
on the connecting port and by setting
the release air pressure (P) lower.
(When the release air is running low,
the pressure inside the tank changes
to vacuum from the positive pressure.
In this case, the pressure is rapidly
released to the atmosphere due to the
check valve.)

If you energize the VQD1151W, you can clean
the suction filter using positive-pressure air
blowing.

Please contact SMC for details.
Added tank
(using piping materials)
Additionally a tank can be
installed.
Possible to add a tank for charging release air in
accordance with the distance (volume) between the unit
from the work piece.

When cleaning (air-blowing), use a pressure of 1.5 MPa
or greater, repeating the process several times but for
less than 2 seconds at a time.
When the distance between work pieces is fluctuated.
