Vacuum Oil

Introduction
At Rubo Al Hail International Enterprise L.L.C., Muscat, Oman, we supply premium‑grade vacuum oil that supports HVAC and refrigeration professionals in achieving reliable system evacuation and maintenance. As a leading AC spare parts supplier in Muscat, we recognise that deep vacuum and proper evacuation are critical pre‑requisites for efficient system performance, especially in large-scale installations and commercial refrigeration venues across Oman. Our vacuum oil is selected for its superior physical‑chemical properties, enabling vacuum pumps to operate at optimum performance, minimise contamination and support system longevity.

What It Does in HVAC Systems
Vacuum oil drives the core lubrication and sealing functions within vacuum pumps used to evacuate HVAC and refrigeration circuits. Before charging refrigerant, systems must be evacuated of air, moisture and non‑condensables — this is achieved using vacuum pumps filled with a high‑quality vacuum oil. The oil forms a critical seal between moving components (rotors, vanes) and the pump housing, maintains lubrication under vacuum conditions, limits vapour back‑streaming, and supports oil‑gas separation. In equipment such as refrigeration racks, chillers and large VRF/VRV systems common in Muscat and Oman’s commercial buildings, using the correct vacuum oil means faster evacuation, better system performance and fewer service callbacks.

Running the pump on sub‑standard oil or mis‑spec’d lubricant leads to slower vacuum draw‑down, higher residual moisture, increased risk of compressor damage or refrigerant contamination. In Oman’s service environment, where ambient humidity and system load are high, the choice of vacuum oil can markedly affect contractor turnaround times, system commissioning quality and long‑term reliability.

Detailed Specifications & Technical Insights
The vacuum oil we supply is engineered for the demanding service conditions encountered in HVAC/R evacuation tasks. Key technical features include:

• Low vapour pressure to minimise vapour back‑streaming into the system and support deep vacuum levels. Oil Store+1 
• High thermal oxidation stability, ensuring the oil resists breakdown even under high pump temperatures, long duty‑cycles or heavy loads. 
• Good demulsibility, enabling separation of entrained moisture or contaminants—essential during evacuation of humid lines common in Oman. 
• Viscosity index tailored for optimal flow under vacuum conditions while providing necessary lubrication for moving parts. 
• Suitable for two‑stage rotary vane, scroll or dry‑vacuum pumps, used in HVAC commissioning, refrigerant recovery and leak‑detection service. 

Additionally, the oil is packaged in formats suitable for service fleets: bulk drums for contractors, smaller jerry‑cans for field service kits, ensuring you maintain proper stock levels and reduce downtime.
