Gardner Denver 21189612118961

The Gardner Denver 2118961 is a high-performance oil-air separator (spin-on, with drain holes) designed for industrial rotary screw air compressors. It is compatible with Gardner Denver and compatible brands such as Atlas Copco and Ingersoll-Rand. Its core function is to achieve ≥99.9% oil separation efficiency through multi-layered glass fiber and composite filter media, significantly reducing oil residue in compressed air, ensuring cleanliness of downstream equipment and reducing oil consumption. This component features a reinforced steel shell, a pressure range of 5–15 bar, and a temperature range of -20°C to 120°C, making it suitable for harsh industrial environments. As an OEM replacement, it allows for quick installation and is widely used in compressor maintenance to extend equipment life and reduce overall costs.

1.Super strong structural stability:
The internal steel frame does not deform under high pressure, avoiding the collapse of the filter element and causing shutdown. Traditional separators may shrink 8% of the surface area under 12 bar pressure, while the 2118961 structure maintains 99.2% effective filtration area.
2.Dual-effect filtration technology:
Multi-layer composite media: captures 0.1μm oil mist particles with a lifespan of 8,000 hours.
Centrifugal drainage design: built-in swirl channel accelerates the discharge of condensed oil and reduces residue.
3.Cross-brand compatibility:
In addition to Gardner Denver, it is also compatible with Atlas Copco and Ingersoll Rand models of the same power (need to check the interface).

1.Automobile manufacturing: Spray robot air supply system to prevent oil pollution on the paint surface;
2.Food packaging: Meet fda oil-free air requirements, used for pneumatic control of filling lines;
3.Pharmaceutical factory: Clean room air source treatment, ISO 8573-1 class 0 certified;
4.Semiconductor workshop: Protect precision instruments from corrosion by oil molecules.

Case: After a dairy factory replaced gardner denver 2118961, the annual failure rate of the compressor decreased by 37%.

1.Metal Welding vs. Adhesive Process
Most low-priced separators use adhesive end caps, which are prone to cracking and oil leakage at high temperatures. 2118961 uses laser welded steel skeleton to ensure the metal welding strength between the end cap and the filter material, and zero leakage at 120°C.
2.Flow Optimization Design
The 5° inclined guide plate (see cross-section diagram) reduces air turbulence, and the pressure drop is 0.2 bar lower than the OEM standard, saving about 4% energy.

1.Cost-effectiveness: Equivalent substitutes are about 50% cheaper than original products.
2.Word-of-mouth verification: 1,239 orders on eBay platform received 98% positive reviews, typical evaluation: "No collapse after 18 months of use, oil content tested up to standard".
3.Warranty commitment: 12-month extended warranty.

1.Global logistics: Free shipping for Hong Kong/mainland orders (DHL 3-day delivery);
2.Technical support: Provide compressor model → separator matching database online query;
3.Emergency response: Spare machine will be sent within 48 hours for faulty parts (deposit required).

Q1: Will the replacement affect the Gardner Denver warranty?
A: No. FTC regulations clearly state: Using compliant third-party parts does not invalidate the warranty (keep the purchase receipt).
Q2: What is the performance difference with the original 2118961 parts?
A: Laboratory comparison shows:
Filtration efficiency: OEM 99.97% vs. replacement 99.94%;
Lifespan: Both up to 8,000 hours (ISO 12500 standard).
Q3: How to verify authenticity?
A: Authentic products provide triple anti-counterfeiting:
The shell has a laser-etched AX18572 steel stamp;
Scan the code to verify the official website warranty.
