Vacuum Filter VFU
Small union type Vacuum Filter.
Corresponding product
-
No copper-based metallic material is used in flow paths
-
HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.
Advantages
Small union type Vacuum Filter.
Small union type Vacuum Filter.
Small vacuum filter is suitable for a high-cycle vacuum operation.
There are 2 selections of element size depending on dust size or exchange period of the element. (Small Union Type: VFU1)
-S3 specification is available for fields requiring "No copper-based metal material is used in airflow paths" and "Low-level Ozone resistance".
HNBR for seal rubber.

Detailed Safety Instructions
Warning
1.Small union type and union type VFU and small plug-in type: VFJ are vacuum filters. Do not use the product in a place where it will remain under pressure. Since it is not an explosion-proof, there is a risk of injury to the human body due to damage of the product.
Caution
1.Perform regular maintenance and inspection of the filter element of the vacuum filter. Clogging of the element may result in poor performance or trouble. When replacing the element, be sure to read and understand the instructions of the replacement of element, and make sure that the internal pressure of the filter is released to atmospheric pressure before replacement to ensure safety. However, the small plug-in type VFJ element cannot be replaced by itself, it must be replaced with a new one.
2.When connecting the piping, check the instructions and the arrows for the air flow direction on the product. Reverse connection does not satisfy the filter function.
3.After removing dust and replacing the element, fix the case securely and make sure there is no vacuum leakage.
Frequently Asked Questions for Vacuum Accessories Series
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."
Tube exhaust and silencer vent are different exhaust methods and can be selected according to the application of the vacuum line.
For vacuum circuit
Due to the cyclone effect and the filter, the air from which dust and water droplets have been removed is discharged to the outlet (fitting) side.
Similar to a general in-line filter, it is a type installed between devices.
Usage example 1
Since it has a larger capacity than the union type, it can collect a lot of dust and reduce the number of maintenance.
When using it for a vacuum pump, etc., install it on the intake side of the vacuum pump.
*) At this time, it is possible to reduce the pulsation of vacuum air by using an air tank together.
For exhaust circuit
The air from which dust and water droplets have been removed by the cyclone effect and the filter is discharged directly to the atmosphere (outside air).
Install at the end of the exhaust. In addition to the purpose of dust accumulation, it can also be used to collect powder (granular material) in air by using it together with the vacuum generator VRL for transporting granules and powder.
Usage example 2
Fine dust that could not be removed is scattered in the atmosphere, so it is not suitable for clean environments.
