Ingersoll Rand Screw Air Compressor Pressure Regulator 35322379

This pressure regulator is a precision-engineered control component designed for Ingersoll Rand screw air compressors. It ensures consistent and stable outlet pressure, protecting downstream systems from fluctuations while optimizing compressor efficiency. Built from high-quality materials with advanced sealing technology, the regulator provides reliable performance even under high pressure and long-term continuous operation.

Application

Air Compressor

Material

Stainless Steel

Description

In a screw air compressor system, maintaining consistent air pressure is crucial to stable operation and energy efficiency. The Ingersoll Rand pressure regulator (P/N: 35322379) is specifically designed to fine-tune and stabilize discharge pressure between the compressor and air distribution network. It automatically adjusts internal valve positions to compensate for changes in flow or demand, ensuring that end tools or production lines always receive a steady air supply.

Unlike generic regulators, this unit is calibrated to match Ingersoll Rand’s factory pressure profiles, providing optimal control range and rapid response to load variations. It plays a critical role in minimizing energy waste, reducing compressor cycling, and extending the service life of pneumatic equipment.

Key Features and Technical Advantages

  1. High-Precision Regulation
    The internal diaphragm and spring assembly are finely tuned to maintain output pressure within tight tolerances. This precision regulation minimizes pressure spikes that could cause leaks, equipment wear, or air waste.
  2. Rugged Construction
    The regulator features an anodized aluminum housing and stainless steel internal components to withstand the constant vibration, oil mist, and high temperatures common in screw compressor systems.
  3. Advanced Sealing System
    The regulator features PTFE and NBR composite seals that maintain a leak-tight seal for thousands of cycles. The double-seal design prevents external leakage and internal bypass, ensuring long-term stable performance.
  4. Easy Installation and Maintenance
    The regulator features standardized port connections and a modular mounting system, allowing for quick installation or replacement without system modification. The design also supports disassembly for cleaning or recalibration.

Working Principle

When air pressure rises above the preset value, the diaphragm mechanism pushes against the spring force to slightly open the relief channel, reducing internal pressure. When pressure falls, the spring returns the valve to its original position, maintaining equilibrium.
This continuous modulation ensures that the downstream air supply remains stable regardless of compressor output variations or sudden load changes in the system.

Quality Control and Testing

Each pressure regulator undergoes:

  • Helium leak detection to ensure zero external leakage
  • Dynamic pressure cycle testing
  • Temperature resistance testing to verify seal durability
  • Calibration and flow verification under simulated compressor load conditions

All regulators are manufactured under ISO quality systems for industrial pneumatic components.

Applications

This regulator is used across a wide range of Ingersoll Rand screw compressor models and systems, particularly where precise pressure control is required.
It’s suitable for:

  • Industrial compressed air lines
  • Automated manufacturing plants
  • Air dryers and filtration units
  • High-precision pneumatic tools and machinery

Maintenance Recommendations

  • Regularly inspect the regulator for dust or oil accumulation on the diaphragm housing.
  • Replace seals every 12–18 months depending on working conditions.
  • Avoid over-tightening fittings to prevent thread deformation or internal leakage.
  • Verify calibration periodically using a certified pressure gauge.
