⚙️ Configurable Options (Selected at Checkout)

This product page allows you to configure the compressor to your application:

• Electrical Options

  • 208/230/460V Three-Phase

  • 230V Single-Phase

• Pressure Options

  • 116 PSI (Standard Pressure)

  • 145 PSI (High Pressure Option)

⚠️ Important Single-Phase Requirement (Please Read)

Single-phase 5 HP models (SES1518) require the installation of an additional external air receiver tank.

This external tank is required to:

• Provide adequate air storage

• Maintain proper compressor cycling

• Ensure long-term scroll pump reliability

➡️ Three-phase models (SES0508) do NOT require an external tank, as they are designed to operate correctly with the internal 13-gallon receiver.

If you’re unsure which configuration is right for your application, our team is happy to review your setup before ordering.
