TRIAX Kompressor MV 46 SAE 20
Full Synthetic, Industrial-Grade: This high-temperature formula offers up to 1000% higher load-bearing capacity than conventional oils. It features a thick, durable film that minimizes metal-to-metal contact during extreme temperatures, protecting bearings and extending service life. The oil is designed for all-season performance, functioning effectively from Arctic cold to high summer heat, reducing the need for seasonal oil changes and separate viscosity grades. OEM-recommended and non-detergent formulation supports long life, with claims of over 20,000 hours of service in demanding environments.
TRIAX Kompressor MV 100 SAE 30
Full Synthetic, Industrial-Grade: Optimized for high-temperature operation with a load-bearing capacity far above conventional oils. It delivers all-season performance due to its true multi-viscosity formulation, functioning from -49°F to 140°F+ without requiring separate viscosity changes. The oil emphasizes longevity with a non-detergent, OEM-aligned formula designed to deliver substantial service life and superior bearing protection against vibration, polish, and wear.
TRIAX Kompressor MV 100 SAE 30 (5 Gallons)
Full Synthetic, Industrial-Grade: This 5-gallon variant mirrors the MV 100 SAE 30 formulation with high-temperature resilience. Its multi-viscosity performance supports consistent lubrication across varying climates, reducing the need for multiple oil changes. With over 20,000 hours of service life claimed, the oil is designed to guard bearings and reduce wear in demanding compressor systems.
TRIAX Kompressor MV 46 / SAE 20 (5 Gallons)
Full Synthetic, Industrial-Grade: The same high-temp, load-bearing formula as the 1-gallon variant, but packaged in a 5-gallon container for larger compressor fleets. It maintains a thick protective film to prevent wear at extreme temperatures and delivers all-season multi-viscosity performance, reducing the need for seasonal adjustments and offering extended bearing protection and life.
Standard 4000 Hour XL Rotary Screw Oil
Partial-Synthetic Blend: This extended-life oil is designed for 4,000-hour service at elevated discharge temperatures (around 212°F). It is compatible with OEM and aftermarket lubricants, with no drain or flush required in many systems. The formulation aims to guard against wear, oxidation, rust, carbon buildup, water contamination, and mechanical stresses, offering an economical option for extended oil life in commercial screw air compressors.
Buying Guide
Key purchase considerations for rotary screw compressor oils:
- Oil type and compatibility: Full synthetic oils typically offer superior high-temperature stability and load-bearing capacity, while partial-synthetic blends can be a balance between cost and performance. Ensure compatibility with your compressor’s OEM recommendations.
- Viscosity and climate: Multi-viscosity formulations adapt to varied climates, helping avoid seasonal oil changes. Consider the operating temperature range of your facility.
- Longevity and service life: Oils promising 20,000+ hours of service life may reduce maintenance frequency, but verify with your equipment’s load and duty cycle.
- Detergent vs non-detergent: Non-detergent formulations often protect bearings and reduce varnish formation in rotary screws, though some OEMs may specify detergent grades for particular systems.
- Size and application: Larger containers (5 gallons) suit fleets or multiple units, while 1-gallon containers are suitable for individual machines or trials.
- Temperature and lubrication film: A high-durability film helps prevent metal wear at high temperatures, especially in heavy load scenarios.
- Maintenance compatibility: Check whether the oil supports drain-and-fill intervals or requires specific maintenance practices to maximize life.
- Cost of ownership: Consider long-term savings from extended oil life and reduced downtime against higher upfront costs of premium synthetic oils.
For facilities running multiple compressors, a uniform oil standard across units can simplify maintenance schedules, spare parts inventories, and compatibility checks. Always verify that chosen oils meet the specific requirements of your compressors, including maximum operating temperature, bearing loads, and OEM guidelines.
