Air Preparation

Positive-Negative Pressure Union Filter

RoHS2 Compliant

Best suitable In-line filter for both positive and negative pressure.

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.
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.

Corresponding product

  • No copper-based metal is used for the metal material. *Some products are only compatible in the flow path.
  • HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.

Advantages

Best suitable In-line filter for both positive and negative pressure.

Use as pre-filtering application for positive pressure.

Easy maintenance.

The element is replaced easily without using tools.

As options, prepared for a '-S3 spec. of "brass-free" and "Low level ozone resistance".

No brass material is used for metal parts and HNBR is used for seal materials.

Detailed Safety Instructions

Warning

1.Since the material of the filter transparent cover is PCTG, Avoid using it in the atmosphere of the chemicals in the following table or in a place where it adheres, as it may be damaged.

2.Always use the slide lock in the locked position. Also, if the joint body is rotated in the locked state or if excessive force is applied to the slide lock, the slide lock may break down and the joint body and the filter cover may be separated and injured.

Caution

1.When used in a circuit that applies vacuum and blow-off (vacuum breaking) air alternately, note that the dust removed by the element may be discharged by the breaking air.

2.When disassembling and reassembling for maintenance, make sure the O-ring is not damaged. Use of a damaged O-ring may cause leakage or other problems.
