The FILME 24121212 Air Oil Separator Cartridge Element Replacement is designed for oil-injected rotary screw air compressors, specifically SSR UP5 UP6 models. This aftermarket maintenance kit helps maintain efficient oil separation, which can reduce varnish formation and moisture carryover that can impact air-end performance. Best for shops needing a straightforward, compatible separator replacement during routine maintenance. Caution: Verify model compatibility with your unit before purchasing to avoid fitment issues. Warranty is noted as 3 months, which is typical for aftermarket maintenance components.
180L Rotary Screw Air Compressor (180ZG) 4.5KW 6HP Oil-Injected
This oil-injected rotary screw air compressor is built for continuous-duty applications in garages, auto shops, and tire service settings. The design supports 145 PSI with a 48-gallon tank, enabling extended operation for impact wrenches, paint sprayers, or tire inflators. It features a pure copper motor and intelligent control for stable operation and an efficient cooling system to prevent overheating during long sessions. Best for busy service bays that require reliable air supply. Limitation: Heavy unit that may require dedicated mounting space and adequate electrical supply (220V/380V).
180L Rotary Screw Air Compressor (380V) 4.5KW 6HP Oil-Injected
This model mirrors the 180ZG but is configured for 380-volt electrical supply, making it suitable for larger shops with higher power needs. It provides the same 145 PSI and 48-gallon tank benefits, enabling sustained operation for tools like impact wrenches and spray systems. Best for larger facilities or technicians who require more robust electrical infrastructure. Caution: 380V power is not compatible with standard 120V outlets.
180L Rotary Screw Air Compressor (220V) 4.5KW 6HP Oil-Injected
This unit is similar to the 380V variant but is configured for 220V power. It maintains the same performance envelope with a 145 PSI rating and a 48-gallon tank. Best for shops that operate on standard 220V power circuits or where 380V is not available. Limitation: Availability of 220V circuits should be confirmed before purchase to prevent electrical issues.
TriboDyn Tri-Guard 3046 ISO 46 Synthetic Oil
TriboDyn Tri-Guard 3046 ISO 46 is a fully synthetic oil designed for rotary screw compressors. It features an extended drain interval and technology to resist varnish buildup, which helps keep oil passages, coolers, and separators clean. Best for high-heat environments or operations that prioritize longer maintenance cycles. Consideration: Check your unit’s viscosity requirements before switching to a higherViscosity oil to avoid reduced flow at startup in cold weather.
TRIAX Kompressor ISO 100 SAE 30 Full Synthetic Oil
TRIAX Kompressor ISO 100 SAE 30 is a full synthetic lubricant designed for rotary, vane, screw, and reciprocal compressors. It provides high-temperature performance, strong load-bearing capabilities, and extended service life. Best for mixed-use fleets or facilities with diverse compressor types, where a single oil helps simplify inventory. Caution: Ensure compatibility with your current oil grade if replacing previously used blends to maintain optimal lubrication film strength.
Compressor Lubricant XL 4000 Hour (1 Gallon)
CompressedAirUSA’s XL 4000 Hour Rotary Screw Lubricating Oil is a partial-synthetic blend designed for extended life and OEM compatibility. It promises 4,000-hour oil life at elevated discharge temperatures and is compatible with OEM and aftermarket equivalents. Best for facilities seeking longer drain intervals without sacrificing performance. Limitation: Some users may require seasonal oil changes in regions with extreme temperature swings, despite extended life claims.
Buying Guide
What to consider when choosing oils and separators for oil-injected rotary screws
- Oil compatibility: Match viscosity and type (synthetic, partial-synthetic, or mineral blend) with your compressor’s specifications and operating temperature range.
- Drain interval: If you prioritize fewer oil changes, opt for oils marketed with extended drain intervals, but confirm compatibility with your unit.
- Varnish and sludge protection: Look for additives and formulation designed to resist varnish formation and sludge buildup in high-heat environments.
- Moisture separation: For oil separators, consider cartridges with proven moisture separation capability to protect the air-end and coolers.
- Electrical and space considerations: High-powered or multiple-voltage units require appropriate electrical supply and space planning in your shop.
- OEM compatibility: When possible, select oils and separators that align with your compressor’s OEM recommendations to minimize risk of lubrication-related issues.
How to choose between full synthetic vs partial-synthetic oils
- Full synthetic oils typically perform better under high temperature, heavy-load conditions and offer longer life.
- Partial-synthetic blends can be a cost-effective upgrade that still provides good protection, but may have shorter drain intervals.
- Consider climate and maintenance schedule: extreme temperatures may justify full synthetic for reliability.
Maintenance planning tips
- Keep a maintenance log for oil changes, separator element replacements, and filter upkeep to prevent downtime.
- Regularly inspect air-end coolers and separators for varnish and sludge deposits.
- Schedule separator element replacements in line with operator manuals or observed performance changes.
FAQ
- Q: Do these oils work with all oil-injected rotary screw compressors? A: They are designed for broad compatibility but always verify your model’s viscosity and type requirements before switching.
- Q: How often should I replace an oil separator element? A: Replacement intervals depend on usage and environment; follow OEM or maintenance guidelines and monitor for pressure drop changes.
- Q: Is synthetic oil always better than conventional oils? A: Synthetic oils offer better high-temperature stability and longer life in many cases, but consider cost and compatibility for your specific model.
- Q: Can I switch oils mid-cycle, or do I need a flush? A: Check your compressor’s guidance; some systems allow a direct switch, while others require a complete flush.
- Q: What is the main benefit of a longer drain interval oil? A: Fewer oil changes reduce maintenance downtime and labor, but verify that the oil still meets your unit’s protection needs.
- Q: Should I replace multiple components at once? A: When performing a major service, replacing the separator, filters, and oil is often efficient to prevent future downtime.
