Vacuum Generator, Multitasking / Manifold
Multi-function vacuum generator module VN
The space-saving vacuum generator equipped with direct-operated solenoid valves is best suitable for high-speed and stable response
Advantages
The space-saving vacuum generator equipped with direct-operated solenoid valves is best suitable for high-speed and stable response
The low-profile vacuum generator is suitable for small space use.
Small size and lightweight
High speed, yet stable response is realized.(ON/OFF=Max. 5msec)
Direct operated solenoid valve is used for the main valve.
Tiny work piece is removed gently when releaseing vacuum with blow-off.
A dedicated blow-off air supply port is provided as configuration option, which enables pressure control by an external pressure regulator for fine-adjusted puff-air delivery.
Common supply port type is also available.
*Air supply port for vacuum generation and blow-off are common.
20L/min. of vacuum release (blow-off) air flow is secured.
Supply pressure: 0.5MPa
Two types of analog output sensor switches and four types of LED display sensors are offered. Digital indicator is provided as option for an analog type of sensor.
We offer two types of analog sensors, for negative pressure and for compound pressure that can be combined with a LCD indicator, and four types of LED display sensors that features one analog output+two switch outputs, NPN/PNP transistor output for negative pressure and compound pressure.
The pressure sensor cable for negative pressure has been changed to a connector type.

Detailed Safety Instructions
Warning
1.If continuous current is supplied to the solenoid for 15 minutes or longer, please limit the number of such energizations to 10 times per day maximum.
2.The solenoid valve of this product uses a current limit circuit, which is a feature that reduces the current value when the coil is kept energized. Do not use in environments subject to vibrations or shocks outside the specifications. It may lead to troubles such as valve malfunction.
3.Tighten screws with appropriate tightening torque referring to the digital catalog. Improper tightening may cause an air leakage, a falling off of the product or damages to the product.
Caution
1.This product is not equipped with a vacuum filter. Be sure to use PISCO vacuum filter series together. If a vacuum filter is not used, dust and dirt can accumulate inside the product, causing poor vacuum performance, leaks and malfunctioning of the solenoid valve. (Recommended vacuum filters: VFU series, VFJ series)
Frequently Asked Questions for Vacuum Generator, Multitasking / Manifold Series
VUS011-NW and FVXS-DW-1 are not the type of the product itself, but the type of "sensor" installed in the product. The official model code of the product is laser marked (or labeled) on the body. FVUS011-** is the sensor for Vacuum Generator VK, and FVXS-** is the sensor for Vacuum Generator VX (External Vacuum Controller VXP / VXPT).
The type of our vacuum generator complex type (External Vacuum Controller) starts with "V". (VG ..., VQ ... etc.)
The sensor model code may start with FV ... and may be written as [PRESSURE SWITCH].
The sensor model code is described only in the specifications with a sensor.
"Tube exhaust type" which does not exhaust air and installing a silencer are recommended.
However, be aware when smooth plumbing without resistance is not carried out such as with too long tube to exhaust, it becomes resistance to exhaust and impair the vacuum degree.
The vacuum characteristic of each type is different.
【H type】
High-vacuum type (Rated supply pressure* : 0.5Mpa)
【L type】
Large-flow type (Rated supply pressure* : 0.5Mpa)
【E type】
High-vacuum at low air pressure supply type (Rated supply pressure* : 0.35Mpa)
For high-vacuum, H type, to provide large-suction flow, L type, and to save supply air, E type is recommended respectively. (Details of final vacuum and suction flow are determined by choice of the nozzle diameter.
*)
What is rated supply pressure?
Rated supply pressure guarantees product performance under the designated conditions and is also the supply pressure, which a vacuum generator supplies, of basis to design and use. The ultimate vacuum reaches to the max. around the rated supply pressure value.
The following graph shows the case of H type. The ultimate vacuum is the highest near 0.5Mpa. (ex. Simple vacuum generator VHH07 (Nozzle dia. 07: ø0.7mm)
When the product performance is reduced, the followings can be the causes.
Please check the product in terms of these points.
1) Check the supply air
Please check if the supply air flow volume and the air pressure are sufficient.
2) Check the nozzle clogging
When foreign substances are clogged in the nozzle, do flushing to clean it.
3)Clogging of the vacuum filter on sucking side or the silencer on the exhaust side.
When a filter is clogged, replace it with new one.
Rated supply pressure of Vacuum Generator is designated according to the vacuum characteristics (H, L and E type) respectively.
This rated supply pressure is required air pressure to start operating Vacuum Generator. When the supply air pressure is under the rated supply pressure, abnormal sound may be caused by some particular supply pressure.
During abnormal sound is being generated, the vacuum characteristics may become unstable and cause troubles such as influencing pressure detection by a sensor. Reset the product to keep the supply pressure satisfying the rated supply pressure in that case. ( Product spec. is the value in operation of Vacuum Generator.)
Both types indicate the valve position when the valve is unactuated. (normal position).
Normally closed type (N. C.)
Normal position is closed, covering a valve . When the valve is actuated, or electricity flows, the valve opens.
Normally open type (N. O.)
Normal position is open, uncovering a valve. When the valve is actuated, or electricity flows, the valve closes.
With the valve unactuated, the entrance leads to the exit.
There are two ways of measuring pressure, absolute pressure and gauge pressure.
Absolute pressure
Absolute pressure is zero-referenced against a perfect vacuum.
It is commonly used to measure flow rate.
When indicated, "abs" is inserted following the unit, for example 10 kPa abs.
Gauge pressure
Gauge pressure is zero-referenced against ambient air pressure.
It indicate how much pressure per 1cm2 is against the ambient air pressure. It is commonly used for indication of manometer. When the pressure is over the ambient air pressure, it is called "positive pressure" and when it is under the ambient air pressure, it is called "negative pressure."
