ZU-A, Vacuum Generator, In-line Style
ZU*A series in-line vacuum generators combine design simplicity with high performance. Also, these generators are often smaller and lighter that the bulky vacuum lines used in central vacuum systems. The slim ZU*A generators are extra compact.
- O.D. is 10.4mm
- Lightweight and comact
- Short overall length
- -90 kPA maximum vacuum pressure
- Options for one touch fitting or femal thread
- 2 nozzle sizes available

Precautions
Be sure to read this before handling
the products. Refer to the back cov-
er for safety instructions. For vacu-
um equipment precautions, refer to
the “Handling Precautions for SMC
Products” and the “Operation Manu-
al” on the SMC website: http://www.

Mounting
Caution
1 .
When the product is mounted in between
piping, the piping on both the P port and
V port should be adequately supported
to avoid causing unnecessary loading
and stressing of the product which may
lead to performance issues or damage to
the body of the product.
When mounting the product, please do
not block the exhaust port at the center
of the body as this may cause performance
issues.
Piping
Caution
1. Piping diameter
The piping diameter for each port should be the
standard size of One-touch fitting. If the piping
diameter is reduced, it may lead to insufficient
flow of supply air, reduction of suction flow and
reduction in the vacuum pressure.
Model Selection
Caution
1. Supply valve
Select the supply valve which can supply suffi-
cient flow rate compared with the ejector air
consumption. If the flow rate of the supply valve
is insufficient, it may lead to vacuum failure. The
selected supply valve should at least have the C
factor shown in the table below.

Air Supply
Caution
1. Quality of supply air
Use clean compressed air as fluid. (Air quality
class 2 : 4 : 3, 2 : 5 : 3, or 2 : 6 : 3 as specified in
ISO 8573-1: 2010 is recommended.)
If impurity enters the product, vacuum perform-
ance might be reduced due to deterioration of
air passage and clogging of exhaust system.
