• Connections: Flanged
• Materials: Steel
• Medium: Glycol-based cold brine refrigerant EN 378 p. 1 (e.g. NH3, R134a, R290 (propane), R507), compatible with blends of refrigerant oil, neutral gases, and liquid media, as well as glycol-based cold brine.
• Pressure Rating: PS25
• Temperature Range: -60 to +150 degC Max
• Design Notes:
  • (a) Mesh sizes available: 100 / 120 / 200 / 250 / 500
  • (b) Can be provided with an integrated check valve or shut-off valve.

By incorporating high-quality refrigeration suction filters into your systems, you ensure the protection and efficiency of your refrigeration processes, making them an indispensable choice for both residential and commercial applications.
