Below we will comprehensively analyze this key component from technical parameters to application scenarios.

This airend, model A11917574, is an OEM replacement part for Gardner Denver rotary screw air compressors and is specifically designed for repair and maintenance of industrial-grade rotary screw air compressors. It is newly manufactured and compatible with leading brands such as CompAir and Gardner Denver, supporting core functions such as oil-gas separation and efficient compression. It comes with a six-month warranty, a minimum order quantity of one piece, and a delivery time of just one to three business days. Suitable for use in a variety of industries, including construction, manufacturing, and mining, it ensures long-term, stable operation of the compressor and reduces the risk of downtime.

1.High-efficiency power output
Adopting asymmetric twin-screw profile design, the volumetric efficiency is increased by 15%. Even under 7-13 Bar variable pressure conditions, the displacement is still kept stable at 6.2m³/min, significantly reducing the unit gas production energy consumption.
2.Ultra-long service life design
Rigid rotor structure: The nitrided steel rotor is dynamically balanced and calibrated (G2.5 grade), and the deformation resistance is increased by 40%.
Heavy-duty bearing system: SKF/NSK grade bearings, grease life of up to 16,000 hours.
Seal protection upgrade: multi-layer engineering plastic sealing ring to prevent oil and gas mixing and extend the oil replacement cycle.
3.Intelligent maintenance support
The reserved vibration sensor interface can be connected to the Internet of Things monitoring system to provide real-time feedback of rotor eccentricity and temperature data to achieve predictive maintenance.

This airend for gardner denver screw air compressor is designed for harsh industrial environments. Typical applications include:
1.Manufacturing: Pneumatic tools for automobile assembly lines, cnc machine tool clamping systems
2.Food and medicine: Packaging machinery and filling equipment that meet oil-free certification (class 0).
3.Textile and chemical: Large-flow jet looms, pneumatic material conveying
4.Energy infrastructure: Power plant instrument air source, pipeline pneumatic valve control.

Especially suitable for working conditions that require 24-hour continuous operation, the high-temperature resistant design (≤110℃) of the a11917574 model ensures stable operation in high-temperature workshops.

1.Precision manufacturing process
Each A11917574 air end must pass 36 quality inspection processes, including:
Three-coordinate measuring machine to detect rotor meshing clearance (accuracy ±0.003mm)
2.Helium leak test to ensure cavity air tightness
72-hour load endurance test (13Bar full pressure condition)
3.Modular compatible design
Retain Gardner Denver original interface standards, no need to modify pipelines or bases, support direct replacement of the following models:
GD R series fixed speed models
GD X series variable frequency models
GHH-Rand old screw machine upgrade

1.Brand Technology Endorsement
Gardner Denver, as a global leader in compression systems, clearly states in its screw technology white paper that the two-stage compressed air end has a full-load efficiency rating of 5 stars (the highest in the industry), which saves more than 18% energy compared to a single-stage structure. The A11917574 is manufactured in strict accordance with this design standard.
2.User Verification Report
In a test case at a North American paper mill, the GD compressor that replaced old components with this air end:
Annual operating energy consumption decreased by 18,200 kWh
Abnormal vibration value decreased from 7.5 mm/s to 2.1 mm/s
Maintenance interval extended from 2000 hours to 4000 hours

1.Global logistics support

• Free shipping policy: Free expedited shipping for orders over $1000 (DHL 2-5 working days)
• Customs clearance cooperation: Provide COO certificate of origin, HS code filing support
• Emergency transfer: US domestic warehouse reserves regular models, support 72 hours delivery

2.Professional technical guarantee

• Pre-purchase consultation: Non-professionals must contact the technical team before purchase to avoid selection errors
• Installation guidance: Provide dynamic centering calibration video tutorial and torque parameter manual

Q1: Is A11917574 suitable for other brands of compressors?
A:Not recommended. This model is designed for Gardner Denver screw compressors, and the interface size and lubrication circuit are customized. If you need to adapt to other brands, you need to provide the host model to evaluate compatibility.
Q2: How to prevent damage to precision parts during transportation?
A:Three-layer protective packaging: inner layer anti-rust oil seal, middle layer anti-vibration EPS mold, outer layer reinforced wooden box. Please unpack and check whether the rotor locking belt is intact immediately after arrival.
Q3: Does the warranty include on-site repair?
A:12-month limited warranty is provided. If the failure is caused by a defect in the product itself:
In China: technicians are supported to come to the site for inspection
Overseas customers: can be returned to the nearest service outlet (freight is borne by both parties)
Q4: Can you provide energy-saving transformation solutions?
A:Yes. For old GD screw compressors, we can provide an integrated upgrade kit of "air end + variable frequency controller", with an average power saving rate of more than 25%. Current operating data must be provided to customize the solution.
