Complete Castrol coverage across the castrol aircol compressor oils family.
Standard mineral compressor oil ISO VG 32, 46, 68, 100 for rotary screw and reciprocating air compressors. Per ISO 6743-3 DAA, DAB. 4000-6000 hour drain interval typical. R&O inhibited, anti-foam, anti-wear additive package. The high-volume Castrol compressor oil for general industrial service.
PAO synthetic compressor oil ISO VG 32, 46, 68 for rotary screw compressors at extended drain (8000-12000 hr typical). Higher tolerance for discharge-temperature spikes (sustained 90-110°C). Lower volatility — reduced oil carry-over into condensate. For high-uptime compressed-air services.
Premium synthetic compressor oil for the most demanding rotary-screw service and the longest drain intervals (12000-15000+ hr). Selected when compressor downtime cost dominates oil-spend cost. For continuous-duty critical-service compressors.
Vane-compressor specific grades and Castrol Aircol R for reciprocating compressors with high oil-circulation. Selection by compressor type, discharge pressure, and ambient-condition profile.
Where compressor specs match hydraulic-fluid requirements (some smaller reciprocating units), Castrol Hyspin AWH may also be appropriate. Cross-reference OEM-recommendation matrix with our technical team to confirm.
Standard property values across the range. TDS / MSDS / per-batch COA available on enquiry.

Where Castrol Aircol Compressor Oils ship from our Hyderabad warehouse — by industry segment + application profile.
Hyderabad pharma cluster (Bollaram, Patancheru, Jeedimetla) — clean-air compressed-air systems for tablet pressing, capsule filling, packaging. Aircol SR / XR for low-volatility (reduces aerosol carry-over) + extended drain for clean-room continuous service.
Aircol SR for food-plant compressed-air where downstream filtration must catch any trace aerosol. Lower volatility = less downstream filter loading. For ISO 8573-1 Class 1 air-quality requirements.
Aircol PD ISO VG 46 / 68 for tier-1 / tier-2 automotive-supplier rotary-screw compressors providing pneumatic-tool air, paint-shop air, assembly-line pneumatics. Atlas Copco, Ingersoll Rand, ELGI installed-base.
Aircol PD for high-discharge-temperature reciprocating compressors in steel mills + heavy-engineering plants. Pairs with Spheerol greases for compressor-bearing service.
Aircol PD for portable diesel-driven and electric-driven construction-and-mining compressors. Tougher service profile — dust ingress, ambient-temperature swings, intermittent operation.
Where the compressor itself sits in the food/pharma-zone or the discharge directly contacts product, Castrol Optileb food-grade equivalents may be required — see our Optileb page for NSF H1 alternatives.

Common questions from maintenance + procurement buyers sourcing Castrol Aircol Compressor Oils through Vasundhara Specialities.
For Atlas Copco rotary-screw compressors at 8 bar discharge in Hyderabad's 30-42°C ambient: Aircol PD 46 (ISO VG 46) is the standard mineral-grade specification, 4000-6000 hour drain. For longer drain (8000-12000 hr) or high-uptime critical service: upgrade to Aircol SR 46 PAO synthetic. Always cross-check the specific Atlas Copco model's OEM lubricant chart — some models specifically require synthetic from new.
Aircol PD is mineral; Aircol SR is PAO synthetic. SR runs 2-3× longer drain interval, tolerates 10-15°C higher discharge temperatures, and produces less oil carry-over into compressed-air condensate. Synthetic premium pays back when: (1) drain interval is the operational bottleneck, (2) compressor sees high discharge temperatures consistently, (3) oil-mist downstream contamination is an HSE / product-quality concern. For typical 4000-hr-drain general-industrial service, mineral PD is cost-effective.
Pharma compressed-air systems with proper filtration and stable operating temperature (75-95°C oil temperature): Aircol SR runs 8000-12000 hour drain interval typical. Oil-condition monitoring (TAN trend, viscosity drift, water content) typically extends this to 15000+ hours. Vasundhara Specialities supports periodic sample analysis as part of the supply relationship.
Yes. Aircol PD is fully miscible with Mobil Rarus, Shell Corena and Total Dacnis mineral compressor oils for top-up and changeover purposes. For full performance benefit on first-fill of a new compressor or after rebuild, follow OEM flush-and-fill recommendation. For PAO synthetic transitions (Aircol SR), full system flush with mineral grade purge is recommended to clear any varnish deposits before synthetic charge.
Standard Aircol PD / SR / XR grades are NOT NSF H1 certified — they are industrial compressor oils. For applications where the compressor is in the food/pharma zone or compressed air may contact food product directly, use Castrol Optileb food-grade compressor oil — see our Optileb page for the NSF H1 range. Aircol covers general industrial compressed-air; Optileb covers food-grade.
Aircol PD has been used in some rotary-vane vacuum pumps where the OEM specifies a turbine-grade or compressor-grade oil. However, dedicated vacuum-pump lubricants typically have lower vapour pressure and better dewatering — for serious vacuum-pump service, OEM-specific vacuum-pump oil is preferred. For standard rotary-vane industrial vacuum pumps in non-critical service, Aircol PD 100 is often acceptable. Cross-reference the specific OEM model.
Standard pack sizes: 20L pail (sample/single-machine top-up), 210L drum (standard plant maintenance), 1000L IBC tote (bulk/high-volume), and bulk-tanker direct-to-tank for large installations. Aircol SR / XR PAO synthetics typically available in 20L and 210L formats. Bulk pricing on volumes >1000L.
