Gardner Denver AEON 4000 (OEM Part Number 28H252) one‑gallon semi‑synthetic screw compressor lubricant is engineered for heavy‑duty industrial screw air compressors operating under continuous‑run, high‑temperature and dusty working conditions.

Many plant operators struggle with frequent oil degradation, valve varnish build‑up, separator element clogging, unexpected shutdowns and high maintenance costs caused by low‑grade mineral compressor oils. Formulated with hydrotreated base stocks plus proprietary antioxidant additives, AEON 4000 28H252 is built to mitigate those real‑world pain points.

Delivering up to 4000 operating hours service life under standard working conditions, this semi‑synthetic lubricant outperforms conventional mineral compressor oil by three times. It suppresses varnish and sludge accumulation, cuts down power consumption, lowers top‑up oil demand, and extends maintenance intervals, helping factories reduce total operational cost of ownership instead of merely meeting basic lubrication requirements.

•Extended 4,000‑Hour Service Cycle

Compared with standard mineral compressor oil, AEON 4000 28H252 triples oil service intervals. Less frequent oil change reduces labor hours, used‑oil disposal expense and machine downtime caused by routine maintenance.

•Energy‑Saving Performance Under Heavy Load

Hydraulic lab validations prove minimized oil thickening during long‑time operation. Stable viscosity can help cut compressor power consumption up to 8%, bringing measurable electricity savings for plants running compressors 24/7.

•Prevent Unplanned Production Downtime

The special additive package restricts valve scaling, carbon deposit and air‑oil separator clogging. Avoid costly emergency shutdown and component replacement triggered by lubricant deterioration in harsh workshops, foundry or mine sites.

•Low Volatility Reduces Oil Top‑Up Frequency by 40%

Low‑volatility semi‑synthetic formula slows oil consumption. Operators spend less time checking and refilling lubricant, especially for remote‑site mobile compressors.

•Wide Temperature Tolerance for Variable Working Environment

High flash point 230°C delivers thermal stability under high working temperature; pour point ‑24°C ensures good fluidity for cold‑start in low‑temperature conditions.

1. Industrial Screw Air Compressors

Perfect match for Gardner Denver and compatible screw compressors deployed in manufacturing workshops, foundries with continuous high‑temperature running load.

2. Oil & Gas Drilling Auxiliary Equipment

Lubrication for compressors and pumps exposed to heavy dust, moisture and non‑stop circulation working mode.

3. Construction & Mining Mobile Compressors

Service mobile air compressors driving pneumatic tools on construction sites, where impact, dust and temperature fluctuation frequently occur.

•Not designed for reciprocating piston compressors with special detergent‑type lubrication requirement.

•If your compressor runs constantly over 100°C discharge temperature, select full‑synthetic compressor oil for longer service cycle instead of this semi‑synthetic grade.

•Not fit for food‑grade / food contact compressed‑air systems (please turn to food‑safe compressor oil series).

Oil Change Installation Procedure

1. Complete oil draining when compressor reaches 60°C operating temperature. Warm oil helps flush sludge and old residual contaminants inside the system.

2. Fully drain waste lubricant before refilling AEON 4000 28H252 one‑gallon oil. Do not mix different grades or different base‑stock compressor oils.

3. Fill new oil until sight glass reaches approximately 80% level; avoid overfilling which will cause high oil carry‑over and separator overload.

4. After refilling, run compressor under idle status for 10 minutes, then check oil level again after shutdown and cooling.

Critical Reminder：Never blend semi‑synthetic, mineral and fully‑synthetic lubricants from different series. Oil mixing may trigger additive reaction, accelerate varnish forming and shorten service life sharply.

Routine Maintenance Tips

1. Oil Condition Monitoring

Regularly observe oil color. Once oil turns far darker than amber/yellow tone, it indicates contamination or thermal degradation. Conduct full inspection and oil replacement regardless of running‑hour counter. Annual comprehensive lubricant inspection is suggested for heavily‑loaded machines.

2. Filter Replacement Schedule

First oil filter replacement: after initial 500 running hours. Subsequent filter change: every 2000 operating hours together with routine inspection.

3. Adjust Service Life according to Actual Working Environment

The rated 4000‑hour life is under standard working condition. If your site is high‑dust, high‑humidity or discharge temperature persistently high, you should shorten oil‑change cycle to 2500‑3000 hours.

Q1: Can I mix 28H252 AEON4000 with other brands compressor oil?

A: We strongly advise against mixing lubricants of different base stocks or different additive systems. Oil blending may lead to additive failure, sludge formation and unexpected component damage. Fully drain and flush system before switching oil grade.

Q2: Does 4000‑hour service life apply for all working environments?

A: 4000 hours is rated under standard working conditions. For high‑dust, high‑humidity or over‑temperature operating environment, shorten oil‑change cycle accordingly.

Q3: Is 28H252 one‑gallon oil compatible with piston air compressor?

A: This is screw compressor‑oriented semi‑synthetic oil, not recommended for piston reciprocating compressors. Please contact us for correct piston compressor lubricant recommendation.

Q4: What is the difference between semi‑synthetic AEON4000 and fully‑synthetic Gardner Denver compressor oil?

A: Semi‑synthetic AEON4000 (28H252) balances cost and performance for most general‑duty screw compressors with 4000‑hr life. Fully‑synthetic grade supports up to 8000‑10000 running hours for 24‑7 continuous heavy‑load machines with higher unit cost.

Q5: How to judge whether I need to replace compressor oil in advance?

A: Watch for oil darkening, foam inside sight glass, abnormal compressor temperature rise, frequent separator blockage. These signals mean oil degradation even if running‑hour counter has not reached rated value.
