DWW Series Rig Air Compressor

Product Overview

Rig air compressors are the core air supply equipment for all drilling operations, supporting drill pipe handling, BOP control, pneumatic tools and cementing work. Our DWW series drilling air compressors are developed with 35 years oilfield experience, applied in over 1,200 drilling sites across 32 countries.

All units pass strict factory test, conform to API 11P, ISO 8573-1 (Class 1-4-1 air quality) and CE standards, available in air-cooled & water-cooled, fixed speed & VSD, standard & explosion-proof versions for desert, plateau, offshore and H2S sour wells.

Core Advantages

Stellite alloy valve plates with HVOF coating, 3 times longer service life, MTBF up to 22,000 hours, 57% higher than industry average
Adaptive cooling + marine anti-corrosion design, wide operating temperature -25℃~85℃, IP66/IP67 protection for offshore salt spray
Ultra-low oil carryover ≤1 ppm, cut maintenance cost by 30%; global warehouse support 24–72h spare parts delivery
VSD energy saving option, redundant cooling system, remote SCADA monitoring, DNV GL & NACE certified for deepwater sour service
