Detailed Safety Instructions
Warning
1.Perform periodical maintenance and inspection of the filter element. Clogging of the element may result in poor performance or trouble. When replacing the element, be sure to understand the dust removal method and the filter replacement element in the instructions, and make sure that the internal pressure of the filter is released to atmospheric pressure before replacement to ensure safety.
Caution
1.Caution for installation and removal of the main unit (1) Use the appropriate tools when installing and removing the product. (2) When installing, refer to the tightening torque shown in the following table and tighten.
2.For the usage environment of the vacuum filter, be sure to read the caution of the "Common Safety Instructions for Vacuum Series".
Frequently Asked Questions for Vacuum Pad Series
The highest operative temperature limit depends on the pad material. For Urethane rubber's highest operative limit is 60℃, nitrile rubber's 110℃, and fluorine rubber's 230℃. (For the other rubber materials' highest limits, please refer to our catalogue.)
The above highest operative temperature limit is for only instant use. When the product is used under the highest operative temperature limit for a certain length of time, careful attentions are necessary.
Request of spring force change will be treated as a special order request in PISCO. Please contact your nearest sales office.
*) Please note that we cannot always meet a request of changing the spring force.
Yes, they are.
For the standard holder types such as VPC and VPD, the key way machined on the shaft gets fit with the rotation-lock thread so that it prevents the shaft rotation.
For small sized pad holders such as VPMC and VPMD, shaft itself is hexagonally machined which prevents rotation.
It is possible to minimize suction force decline of a vacuum pad by installing a fall prevention valve on multiple vacuum pads even when there are un-sucking pads.
The fall prevention valve, however, does not completely shut down the air circuit and it sucks a little amount of air. Depending on the number of un-sucking pads, required vacuum for the air circuit may not be achieved.
Besides, in case of sucking one work peace by multiple Vacuum Pads, even when the fall prevention valve can reduce vacuum decline, there is still a possibility that the work peace loose the balance so that the sucking Vacuum Pads may be released.
Please refer to the following "pad inner diameter" of the pad rubber to be attached.
| Pad size | Pad inner diameter |
|---|---|
|
φ1mm |
φ0.5mm |
|
φ2mm |
φ0.6mm |
|
φ3mm |
φ0.8mm |
|
φ4mm |
φ1.2mm |

No pad rubber (pad holder only) |
φ1.6mm |
*) Adsorbable up to this pad diameter
The inner diameter of the pad holder itself of the Air Pincette is φ1.6 mm, but since the pad diameter φ1 to 4 mm mentioned above has a smaller pad inner diameter than that, it is possible to adsorb workpieces of φ1.6 mm or less as shown in the above figure.
The pad inner diameter of the pad size φ6, 8 mm is larger than the pad inner diameter of the holder, so it is suitable for φ1.6 mm or more.
It is a dimensional calculation to the last, and may differ depending on the workpiece to be adsorbed. Ultimately, we ask you to judge the actual machine.
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."
