Reciprocating, drip rotary and light load rotary air compressor oil Additive Package

Description

For reciprocating, drip-type and light-duty rotary air compressor oil additive packages, the goal is to improve compressor oil performance and protection. These additives typically include antiwear agents, antioxidants, corrosion inhibitors, and detergents/dispersants.

Antiwear agents help reduce friction and wear between moving parts in a compressor, such as pistons and cylinders. This helps extend the life of the compressor and reduces the risk of expensive repairs.

Antioxidants are used to prevent oil oxidation, which can cause sludge formation and reduce performance. These additives help maintain the properties of the oil and extend its service life.

Contains corrosion inhibitors to protect the compressor’s internal components from corrosion and rust. This is especially important for compressors exposed to moisture or harsh environments.

Detergents and dispersants are used to keep compressors clean and free of harmful deposits. This helps maintain efficient operation and prevents sludge and varnish build-up.

A high quality reciprocating, drip rotary or light duty rotary air compressor oil additive package will provide enhanced protection against wear, oxidation, corrosion and deposits, helping to extend the life of the compressor and Improve compressor performance.

For reciprocating, drip rotary, and light load rotary air compressors, selecting the right additive package for the base oil is essential to ensure:

• Thermal stability

• Oxidation resistance

• Anti-wear protection

• Carbon and varnish control

• Rust and corrosion prevention

🔧 Recommended Additive Package Components for Air Compressor Oils:

✅ 1. Antioxidants

• Function: Prevent oxidation and oil thickening at high temperatures.

• Recommended Types:

  • Phenolic antioxidants

  • Aromatic amines

  • Phenyl-α-naphthylamine (PANA)

• Importance: Reciprocating compressors especially run hot → risk of deposit formation.

---

✅ 2. Anti-wear Agents

• Function: Protect internal metal parts (especially in reciprocating and rotary types).

• Common Types:

  • ZDDP (Zinc dialkyldithiophosphate) – Moderate levels (non-sludging)

  • Ashless anti-wear agents (phosphorus esters) – Better for clean applications

• Importance: Reduces wear on piston rings, vanes, and bearings under intermittent load.

---

✅ 3. Rust & Corrosion Inhibitors

• Function: Protect internal parts from water vapor and condensation.

• Types:

  • Amine-based rust inhibitors

  • Succinic acid derivatives

• Importance: Especially crucial in drip-fed systems exposed to atmospheric moisture.

---

✅ 4. Detergents / Dispersants (optional in light-duty)

• Function: Keep surfaces clean and control carbon/varnish deposits.

• Considerations:

  • Too much detergent = higher ash → not ideal for rotary compressors

  • Use low-ash or ashless dispersants in rotary systems

---

✅ 5. Foam Inhibitors

• Function: Control air entrainment and foam in oil reservoirs.

• Types:

  • Silicone-based antifoam agents (ppm level)

  • Organic defoamers for ashless systems

---

✅ 6. Viscosity Modifier (Optional)

• Needed only if a multi-grade or high-VI synthetic fluid is desired.

📦 Additive Package Suggestion:

You can also use pre-formulated additive packages designed specifically for air compressor oils, often labeled for:

• ISO VG 32, 46, 68 grades

• Mineral or synthetic base stocks

• Rotary or reciprocating use

✔️ Look for packages conforming to DIN 51506, ISO 6743-3A-DAA/DAB, or Atlas Copco/Quincy/Ingersoll-Rand OEM standards.

Choosing the right additive package ensures:

• Longer oil drain intervals

• Reduced carbon and sludge formation

• Extended compressor life
