Portable Diesel Air Compressors
Power Singapore’s most demanding operations with portable DENAIR diesel compressors. From offshore marine platforms to petrochemical facilities and remote construction sites, the units range from 185-950 CFM deliver reliable compressed air where electrical infrastructure is limited or unavailable.
What makes DENAIR diesel compressors suitable for marine environments?
DENAIR portable diesel compressors are built with heavy-duty components designed for harsh marine conditions. Features include corrosion-resistant materials, weatherproof enclosures, and reliable diesel engines (Cummins, Yanmar, Weichai) that perform consistently in saltwater environments. Our units operate reliably in temperatures and humidity levels typical of Singapore’s marine operations.
What capacity range do you offer for offshore operations?
Our DENAIR diesel compressors range from 5.00 to 45.00 m³/min (185 to 1360 CFM) with pressure capabilities from 7 to 35 bar (20 to 508 PSI). For offshore applications, popular models include the DACY1207 (425 CFM) and DACY2710 (950 CFM) which provide sufficient capacity for marine pneumatic tools and equipment.
View complete specifications and all models.
How long can these compressors run continuously for offshore shifts?
DENAIR diesel compressors are designed for continuous operation. With proper maintenance, units can run 8-12 hour shifts typical of offshore operations. Fuel consumption varies by model – for example, smaller units consume approximately 8-15 liters per hour, while larger units consume 30-65 liters per hour depending on load.
What safety certifications do your compressors meet for marine operations?
Our DENAIR compressors comply with international safety standards including CE certification and Maritime and Port Authority of Singapore (MPA) regulations. They feature comprehensive safety systems: automatic shutdown protection, emergency stop functions, pressure relief valves, and temperature monitoring, built to withstand demanding offshore and marine environments.
What’s the fuel efficiency for marine operations?
Fuel consumption depends on the model and load. Our efficient diesel engines provide:
- Small units (5-10 CFM): 8-15 L/hr
- Medium units (12-20 CFM): 20-30 L/hr
- Large units (25-45 CFM): 45-65 L/hr
This makes them cost-effective for extended offshore operations where fuel logistics are critical.
Can DENAIR diesel compressors handle high-pressure industrial applications?
Absolutely. Our DENAIR range offers units with working pressures up to 35 bar (508 PSI), suitable for demanding petrochemical applications. Models like the DACY3335 and DACY3925 deliver high-pressure compressed air for industrial processes requiring consistent, reliable air supply.
View high-pressure model specifications.
How do these compressors perform in continuous industrial operation?
Our diesel compressors are engineered for continuous duty cycles common in petrochemical plants. With quality engines from Cummins, Yanmar, and Weichai, plus advanced cooling systems, they maintain consistent performance during 24/7 industrial operations with proper maintenance intervals.
What air quality can we expect for sensitive industrial processes?
While our diesel compressors provide reliable compressed air, for sensitive petrochemical processes requiring ultra-clean air, we recommend pairing with our air treatment systems including refrigerant dryers, desiccant dryers, and filtration systems to achieve the required air quality standards.
What CFM rating do I need for construction pneumatic tools?
Common construction tool requirements:
- Jack hammers: 80-100 CFM
- Pneumatic drills: 20-40 CFM
- Impact wrenches: 5-15 CFM
- Multiple tools simultaneously: 150-300+ CFM
Our DACY0810 (300 CFM) or DACY1207 (425 CFM) models are popular for construction sites running multiple pneumatic tools.
Compare all models and specifications.
How portable are these units for job site mobility?
All DENAIR portable units are trailer-mounted for easy transport between job sites. Dimensions range from compact units (2.21m length) to larger units (5.1m length). They feature robust trailer chassis with road-ready wheels and towing hitches for quick relocation as construction projects progress.
What’s the difference between 425 CFM, 750 CFM, and 950 CFM for construction?
- 425 CFM (DACY1207): Suitable for small crews, 2-3 pneumatic tools, light construction work
- 750 CFM (DACY2114): Medium construction sites, 4-6 tools, concrete work, sandblasting
- 950 CFM (DACY2710): Heavy construction, multiple crews, large pneumatic equipment, continuous high-demand applications

How do diesel compressors compare to electric in terms of performance?
Diesel advantages: Independent power source, higher mobility, often more powerful, suitable for remote locations. Electric advantages: Lower operating costs, quieter operation, zero emissions at point of use. Diesel is typically chosen when electrical infrastructure is unavailable or insufficient for the required compressor capacity.
What permits are required for diesel compressors on Singapore construction sites?
Diesel compressors typically require Building and Construction Authority (BCA) permits for construction sites. Additionally, you may need National Environment Agency (NEA) permits for emissions and noise control, especially in urban areas. Work permits may also be required depending on the project scope and location.
What are Singapore’s noise level requirements for construction equipment?
Singapore enforces strict noise control regulations under the Environmental Protection and Management Act. Construction noise is generally limited to 75dB(A) during permitted hours (7 AM to 7 PM on weekdays, 7 AM to 5 PM on Saturdays). Some areas have stricter limits, and our team can help ensure your equipment complies with local requirements.
Are there emissions standards for diesel equipment in Singapore?
Yes, diesel equipment must comply with NEA emissions standards. Our DENAIR compressors meet international emissions requirements and are suitable for use in Singapore’s regulated environment. We can provide emissions documentation for regulatory compliance.
What documentation do you provide for regulatory compliance?
We provide comprehensive documentation including: CE certification certificates, emissions compliance documentation, safety feature specifications, operation and maintenance manuals, technical specification sheets, and insurance and liability documentation.
What maintenance schedule is recommended for DENAIR compressors?
Recommended maintenance schedule: Daily checks (fuel, oil, coolant levels), weekly inspections (air filters, belts, connections), 250-hour service (engine oil and filter changes), 500-hour service (comprehensive inspection and component checks), 1000-hour service (major engine and compressor overhaul), and annual complete safety and performance assessment.
