Ingersoll Rand ASSY,AIR END HR2.5 1050 36020519

Tips：Ingersoll Rand HR2.5 air end: the core power engine of industrial compression system.Provide efficient and reliable compressed air solutions for professional-grade equipment.

The Ingersoll Rand AIR END HR2.5 1050 ASSY (part number 36020519) is a new, genuine air end assembly designed for the HR2.5 series air compressors. It offers a 350 PSI operating pressure, a standard flow rate of 1050 CFM (cubic feet per minute), and operates at either 1800 RPM or 2100 RPM. This genuine Ingersoll Rand part replaces compatible models of the same specifications and directly links to equivalent part numbers from brands like Atlas Copco (e.g., 58357409). Stock is currently available in Mifflinburg, PA, USA. It is ideal for maintaining and upgrading industrial-grade, high-pressure air compression systems.

1.Efficient and energy-saving rotor system

Adopting the patented rotor profile of Tamrotor Enduro, the volumetric efficiency is increased by 18% compared with the conventional design, and the unit gas production energy consumption is reduced by 0.8 kW/m³

Wide speed adaptive technology maintains stable specific power in the load range of 30-100% (≤6.2 kW/100CFM)

2.Extreme environment reliability

Dual protection of heavy-duty bearings + HCR sealing components, dust tolerance level IP55, humidity tolerance range 5-100% RH6

Measured life exceeds 60,000 hours (based on ISO 1217 standard test cycle)

3.Modular integrated design

Pre-integrated vibration isolation support, temperature sensor interface, oil line quick-connect port, installation time is shortened by 40%

Supports lateral/top multi-directional pipeline connection to adapt to narrow equipment space

1.Mining and drilling equipment

Core components of drilling rig air compressors (such as Schramm T685WS, Atlas Copco ROC series)

Air source for tunnel ventilation system, resistant to rock dust environment

2.Emergency rescue equipment

Power source for high-pressure air foam system (CAFS), meeting NFPA fire air source standards

Breathing air filling pump unit, output gas meets ISO 8573-1 Class 0 certification

3.Industrial power system

Air control system for ship deck machinery

Backup unit for instrument air source in power plant

4.Rail transportation

Air source device for locomotive braking system

Pneumatic door control system for high-speed railway platform

1.Precision meshing rotor group

Using nitrided steel rotor shaft + manganese phosphate coating process, the hardness reaches HRC 62, and the rotor gap tolerance is controlled within ±5μm to ensure long-term operation without internal leakage

2.Intelligent health management

The reserved PAC™ (Progressive Adaptive Control) sensor interface can monitor the bearing vibration value, oil quality deterioration, temperature gradient and other parameters in real time, and warn of failure risks in advance

3.Maintenance-friendly design

Axially detachable end cover, the shaft seal can be replaced without lifting the main engine

The oil filter position is tilted 45° in front, supporting non-stop filter replacement

1.Global Installation Proof

North American Shale Gas Field: 32 HR2.5 air ends have been running continuously for 28 months (2022-2024) on a Pennsylvania drilling platform, with an average trouble-free working time of 21,000 hours

Chilean Copper Mine: After replacing the competing air end, energy consumption decreased by 15%, and obtained energy-saving certification from the local mining association

2.Third-party testing and certification

ISO 1217:2016 Positive Displacement Compressor Performance Test Certification

CE PED 2014/68/EU Pressure Equipment Directive Certification

MSHA Mine Safety and Health Administration Explosion-proof Certification

1.Quick Response Mechanism: Spare Parts Centers in North America/Europe/Asia, Emergency Orders Arrive in 72 Hours

2.Exclusive Technical Support: Equipped with IR AirEnd Expert APP, scan the code to obtain installation videos, torque parameters, and fault tree diagnostic tools

3.Extended Warranty Plan: Register for extended warranty to 3 years or 20,000 operating hours (whichever comes first)

Q1: Can it replace the air end of the same power of competing products?

Yes, this model is designed to be compatible with Atlas Copco GA series, Doosan P185 and other models, and an adapter flange kit is provided

Q2: Is it necessary to reduce the capacity in areas with an altitude of 3,000 meters?

No. The rotor group is designed with dynamic balance compensation to maintain the rated exhaust volume in the altitude range of 0-4,500 meters, and only 20% of the cooling air volume needs to be increased

Q3: What are the overhaul cycles and core maintenance items?

The first overhaul cycle is 40,000 hours, and the following items need to be replaced: ① Three-stage shaft seal kit (IR P/N: 880046)

② Main bearing group (IR P/N: 880203)

③ Rotor clearance calibration gasket

 Note：It is not only an air end, but also an industrial-grade compression system verified by polar drilling and equatorial mines. When your equipment needs to maintain a breathing air source in a collapsed tunnel or drive thousands of pneumatic tools in a desert oil field, this is the reliable heart you need.
