Ingersoll Rand RS15i-A125 20hp Premium Rotary Screw Air Compressor

Ingersoll Rand RS15i-A is a 20hp premium quality and industrial grade rotary screw air compressor. Ingersoll Rand works to keep you ahead of your competition with Next Generation R-Series air compressors that lower total cost of ownership through industry leading energy efficiency, reliable components and industry leading delivered capacity.

IR’s rotary screw uses a rugged and reliable compression airend is oil injected with a highly efficient asymmetrical profile rotor. The compressor provides removable service panels for quick, easy access to all user-maintainable components. The superior oil separation allows for cleaner air being sent downstream with less pressure drop across air treatment, leading to a more energy efficient and clean compressed air system. The airend is paired with a IE3 premium energy-efficient motor to support continuous operation in harsh environments. The RS15 fixed speed compressor is designed to handle 24/7/365 operation.

The R-series rotary screw compressor comes standard with the XE-50 rotary compressor controller. The Xe-50M controller provides you with full asset control and increased reliability. Clear, intuitive navigation ensures ease of use with a peace of mind that your system is running as it should.

New to the RS-series compressor is Ingersoll Rand’s V-ShieldTM technology. V-Shield utilizes premium PTFE hoses on all oil-carrying lines as well as o-ring face seal connections. This design virtually eliminates all oil leaks and increases the hose life.

This compressor comes standard as a baseplate configuration without an air receiver. A baseplate compressor is meant to be plumbed into a separate air receiver already installed at the plant. You can also have this unit pre-installed and plumbed on a 120 gallon or 240 gallon air receiver.
