Even high-quality switches can be unsuitable if their pressure range or differential (hysteresis) doesn’t match the compressor’s requirements.
- Selecting a switch with too narrow a pressure band, causing frequent cycling.
- Using a switch rated below the system’s maximum pressure, risking rupture or failure.
Impact: This leads to increased wear on the compressor motor and reduced lifespan of both the switch and compressor.
Mitigation Tip: Match the switch’s pressure rating (e.g., 100–175 psi) and adjustable differential to your compressor’s specifications. Always include a safety margin.
5. Poor Sealing and Gasket Degradation
Even with a high IP rating, poor sealing design or low-quality O-rings/gaskets can compromise protection over time.
- Gaskets made from incompatible materials that degrade when exposed to oil, moisture, or temperature extremes.
- Inadequate sealing around electrical conduits or pressure ports.
Impact: Gradual ingress of contaminants leads to internal corrosion and switch failure.
Mitigation Tip: Choose switches with high-quality, oil-resistant elastomer seals (e.g., NBR or Viton). Inspect seals during installation and maintenance.
By carefully evaluating quality, verifying IP ratings, and ensuring compliance and compatibility, you can avoid these common sourcing pitfalls and ensure reliable, safe operation of your air compressor system.
