Product Introduction
Tips: In industrial compressed air systems, oil separators are core components that guarantee equipment life and air quality. As a Gardner Denver compressor user, when you need to replace the oil separator with the original manufacturer's serial number 03267728, it is crucial to choose a reliable and cost-optimized replacement. This article will comprehensively analyze the technical characteristics and application value of this Gardner Denver oil separator replacement.
The 03267728 oil-gas separator is a critical consumable for Gardner Denver rotary screw air compressors. It efficiently separates lubricating oil from compressed air, ensuring clean air and reducing equipment maintenance costs. It is compatible with Gardner Denver ES/VS series compressors (such as the ES18, ES22, ES30, ES37, VS25, and VS40) and Bottarini KDV30 models. It is also compatible with industrial equipment such as Sandvik 780R and Tamrock drilling rigs. Made of imported fiberglass, it boasts a filtration efficiency of 99%, an initial differential pressure of ≤0.02 MPa, and a typical service life of approximately 3,000-4,500 hours. We provide OEM-grade quality.

Product Features
1. High-efficiency oil-gas separation technology
Through the deeply loaded coalescing filter material, the oil mist particles are forced to collide and aggregate, forming large droplets and then settling by gravity. Compared with ordinary separators, the interception rate of 0.3 micron particles is increased by 40%, significantly reducing the downstream filter element load.
2.Optimized structural stability
Anti-collapse design: The steel end cap and nylon reinforced skeleton ensure that they will not deform under a pressure difference of 7-8psi, avoiding oil direct-through accidents caused by filter element collapse.
Metal welding process: The filter material interface adopts metal welding instead of gluing to eliminate the risk of debonding in high temperature environment.
3.Significant economic benefits
The price is 30%-50% lower than the original parts, and the maintenance cost is reduced. Based on an annual operation of 8,000 hours, a single compressor can save more than $420 in consumables.

Product application areas
This gardner denver oil separator replacement is suitable for the following scenarios:
1.Industrial manufacturing: Painting, pneumatic tool air supply system, scenarios requiring oil-free air.
2.Medical food: In compliance with ISO 8573-1 class 0 oil-free standard, used for pharmaceutical filling and food packaging equipment.
3.Energy field: Compressed air purification of drilling equipment and gas control valve groups.
4.Typical case: After a certain automobile factory used the 03267728 replacement part, the oil content of compressed air dropped from 15ppm to 2ppm, reducing the number of filter element replacements by 3 times per year.

Product details: Scientific installation and fault prevention
1. Key steps of installation
Stop and release pressure → Close the outlet valve → Open the drain valve to confirm the system is under zero pressure.
Remove the bolts of the oil and gas barrel cover and remove the old separator.
The included conductive gasket (including metal guide wire) must be installed, otherwise it may cause static sparks.
Before putting in the new separator, check the length of the return oil pipe - insufficient or excessive insertion depth will cause the residual oil to exceed the standard (standard gap 1-2mm).
2. Common fault attribution
Sudden increase in residual oil: 80% due to blockage or rupture of the return oil pipe, the stainless steel filter of the pipeline needs to be cleaned.
Abnormal increase in pressure difference: Excessive environmental dust (such as mining areas and timber mills) causes premature blockage of the filter element, and a pre-filter needs to be installed.

Product proof: Authoritative certification and user proof
1.Performance benchmark: Third-party testing shows that the pressure drop curve overlaps with the original parts by more than 98%, and the dust holding capacity is increased by 12%.
2.User proof: Among the more than 1,239 after-sales reviews on the eBay platform, 98% confirmed that "no oil carryover" and "no adaptation problems during installation".
3.Warranty commitment: We provide a one-year warranty.
Intimate service
1.Global logistics: Stocked in warehouses in China, the US and Europe, supporting DHL/FedEx 72-hour delivery (except remote areas).
2.Technical support: Provide compressor model → separator matching database, free query of compatibility.
3.Return policy: Full refund is supported for unused products within 30 days (round-trip shipping costs are borne by the buyer).
FAQ Frequently Asked Questions
Q1 Is this separator compatible with all Gardner Denver models?
A: Only applicable to models with 03267728 specified by the original manufacturer, such as 55B7, RELIANT series, etc. Please provide the compressor serial number for confirmation before purchasing.
Q2 Why is the actual life less than 4,000 hours?
A: The life is affected by the working conditions: high temperature (>95℃), high humidity (>80%RH) or dust environment will shorten the life by 50%. It is recommended to shorten the inspection cycle.
Q3 Is the oil smell still strong after installation?
A: After the first start, it needs to run for 20 minutes to exhaust the residual oil mist. If it persists, check whether the return oil pipe check valve is stuck.
Q4 Does the use of a third-party separator affect the original manufacturer's warranty?
A: No. According to the Magnuson-Moss Warranty Act, users have the right to choose non-OEM parts without affecting the warranty of other parts of the compressor.
Note: When the separator pressure difference exceeds 0.12MPa and is not replaced, the motor load will increase by 15%, and long-term operation may cause overheating and sintering of the air end - regular monitoring of the pressure difference is the real cost saving.
This product has been used in mines, automobile factories, and food production lines in more than 30 countries around the world. What you see is not only a Gardner Denver oil separator replacement, but also a set of verified compressed air purification solutions.
