Gardner Denver Oil Separator Element30991358

Tips: As the core filter component of the compressed air system, Gardner Denver Oil Separator Element 30991358 is designed for efficient oil mist separation.

The Gardner Denver 30991358 is a genuine, original, cartridge-style air-oil separator filter designed for industrial compressed air systems. It efficiently separates air and oil from compressed air, ensuring optimal air quality while protecting equipment and extending compressor life. Compatible with select Gardner Denver models, this part minimizes lubricant carryover and meets environmental requirements by preventing oil contamination in condensate drains.
It measures approximately 83 × 213 × 83 mm (L × H × W) and weighs 10 lbs. It is sold as a critical maintenance part and is available through distributors and third-party suppliers. Genuine parts ensure performance consistent with Gardner Denver engineering standards.

1.Ultra-fine separation performance
Using gradient density glass fiber layer and nano-coating technology, it achieves 99.99% interception efficiency for oil droplets above 0.1μm. Compared with ordinary separators, the 30991358 model reduces the residual oil concentration in compressed air to below 3ppm, significantly protecting the back-end equipment from oil pollution.
2.Low pressure difference energy-saving design
The optimized pleated structure increases the effective filtration area by 30%, and the initial pressure difference is only 0.2 bar. The average pressure difference is reduced by 15% during the entire life cycle, reducing the energy loss of the compressor. For example, in a 75kW unit, the annual power saving can reach 2,100kWh.
3.Long-term stable operation
The filter material is wrapped with double-layer epoxy resin, and the anti-oil vapor aging performance is improved by 50%. Even in high temperature and high humidity environments, the structural integrity is maintained to avoid oil path blockage caused by fiber shedding.
4.The snap-on interface designed specifically for Gardner Denver compressors does not require tool assistance for replacement. Compared with compatible models such as EDMAC 3004011086, the original 30991358 can shorten maintenance time by 40%.

Gardner denver oil separator element 30991358 is suitable for industrial scenarios with strict requirements on air quality:
1.Food and medicine: Prevent lubricating oil from contaminating the compressed air of the filling line, in compliance with fda 21 cfr 178.3570 standard.
2.Electronic manufacturing: Protect the precision pneumatic components in smt placement machines and chip packaging equipment.
3.Automotive spraying: Ensure paint adhesion and avoid "fisheye" defects caused by oil mist.
4.Industrial laser: Keep the laser cutting head lens clean and extend the life of optical components.

1.Structural innovation
The internal conical guide cover accelerates the centrifugal separation of oil and gas, with a pre-separation efficiency of 70%, reducing the load on the filter material. The external double-layer sealing ring (nitrile rubber + metal skeleton) achieves zero leakage at a pressure of 13 bar.
2.Material science application
The filter material is treated with oleophobic fluororesin, and the oil droplet contact angle is greater than 120°, which effectively prevents pore blockage caused by oil film coverage. The support layer uses 304 stainless steel mesh with a compressive strength of 35N/cm².
3. Authenticity identification guide
The genuine 30991358 has three anti-counterfeiting features:
The end cap is laser-etched with the GD logo and batch number (non-printed label).
The metal ring is marked on the inside.
The packaging box is affixed with a holographic anti-counterfeiting label, and the supply chain path can be verified by scanning the code.

Q1: Are 30991358 and EDMAC 3004011086 interchangeable?
A: The physical interfaces are compatible, but EDMAC is a third-party replacement. The original 30991358 has a higher glass fiber density and a residual oil rate of 0.8ppm. It is recommended to use original parts under critical conditions.
Q2: How to determine whether the separator needs to be replaced?
A: When the pressure difference is ≥0.5bar (no load), or the oil content of the gas tank drainage increases sharply, the 30991358 separator should be replaced immediately. It is recommended to install a pressure difference alarm for accurate maintenance.
Q3: Can the separator shell be reused?
A: Reuse is prohibited! A new Gardner Denver oil Separator Element 30991358 must be used for each replacement. Micro cracks inside the old shell will cause oil vapor to bypass and contaminate the downstream pipeline.
Q4: Can this separator be installed on non-GD compressors?
A: The interface specifications and pressure ratings need to be confirmed. We provide free compatibility testing - submit your equipment model and a photo of the separation tank to get a modification plan.
