RoHS2 Compliant

Small union type Vacuum Filter.

Resin
  • PBT is used for the main resin parts. PBT: A standard resin material that is ideal for general environments.
Metal
  • Brass with electroless nickel plating is used for the main metal parts.
  • Special stainless steel is used for the main metal parts. Special stainless steel: Corrosion resistance is equivalent to SUS303, making it ideal for environments prone to corrosion.
Seal rubber
  • NBR is used for the seal rubber material. NBR: A material generally used as a sealing material. Please note that it is inferior in ozone resistance.
  • HNBR is used for the seal rubber material. HNBR: A material with improved ozone resistance by adding hydrogen to NBR. Ideal for low-concentration ozone countermeasures.

Corresponding product

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.
