ISO 5782-1:2017

Overview - ISO 5782-1:2017 (Compressed air filters)

ISO 5782-1:2017 is an international standard for pneumatic fluid power - compressed air filters that defines the main characteristics manufacturers must include in supplier literature and the required product marking. It applies to mechanically constructed compressed air filters (aluminium, zinc diecast, brass, steel, plastic) rated up to 1 600 kPa (16 bar) and maximum 80 °C, designed to remove solid and liquid contaminants from compressed air.

Key topics and technical requirements

The standard specifies the minimum descriptive and marking information to help users select and use compressed air filters safely and consistently:

• General characteristics

  • Mandatory general dimensions (Figure 1 style) and port/interface forms (ISO 16030, ISO 7‑1 or Annex A).
  • Rated pressure classification per ISO 2944 and verification per ISO 5782‑2.
  • Declared operating temperature range and alternate ratings when applicable.

• Performance and selection data

  • Pressure drop vs air flow rate measured at inlet pressures of 250, 630 and 1 000 kPa (or rated pressure), reported per ISO 5782‑2 in graphical or tabular form.
  • Useful retention capacity of reservoirs measured per ISO 5782‑2.
  • Draining device types (manual, automatic, etc.) and minimum pressure for drain operation.
  • Materials of construction (body, internals, elastomers, bowl).

• Optional filter efficiency

  • Ability to report particulate filtration efficiency (fine 0.01–<5.0 µm, coarse ≥5.0–≤40 µm) with testing per ISO 12500‑3.
  • Reference to air purity coding from ISO 8573‑1 (Annex B) for water/oil/particulate classes.

• Operation, maintenance and marking

  • Required maintenance guidance (replacement pressure-drop limit, compatible cleaning products, freeze warnings).
  • Mandatory product marking: manufacturer name/trademark, model/type, rated pressure, max temperature, flow direction, nominal micron rating, pneumatic symbol (ISO 1219‑1), manufacture date code, and other items.

Applications and who uses the standard

ISO 5782-1:2017 is used by:

• Manufacturers and suppliers to prepare compliant product literature and markings.
• Product engineers and system integrators to specify filters that match pressure, temperature and contamination-control needs.
• Purchasing and maintenance teams for selection, installation, inspection and lifecycle planning.
• Test laboratories and certification bodies referencing required measurement methods (see ISO 5782‑2).

Practical applications include specifying and documenting compressed air filtration in industrial pneumatic systems, compressed air distribution networks and control-product assemblies where reliable particle and liquid removal is required.
