How to Choose the Right Air Compressor?
What size air compressor and pressure (PSI) do I need for my application?
Compressor sizing depends on both pressure (PSI) and flow rate (CFM) requirements for your specific tools and applications.
- Sandblasting operations:
High-pressure, high-flow units. 750-1000 CFM (DENAIR DACY series recommended) - Spray painting projects:
Consistent pressure for quality finishes. 200-400 CFM depending on gun size and finish quality - Workshop Pneumatic air tools:
Reliable pressure for impact tools, grinders. 400-750 CFM for most workshop tools - Marine/Petrochemical:
Specialized high-capacity continuous operation.
200-1000 CFM for specialized equipment - Backup for stationary units: Match or exceed 80% of your main compressor’s capacity
Our DENAIR portable units deliver up to 508 PSI for high-pressure industrial applications.

How do I calculate my CFM requirements?
Air flow requirements vary significantly based on your specific tools, operating conditions, and usage patterns. Rather than risk undersizing or oversizing your compressor, our technical team provides consultations to calculate your exact CFM needs.
Contact us at +65 8847 6838 or sales@vutechnology.com.sg with details about:
- Your tools and equipment
- How many operate simultaneously
- Your industry and application type
- Operating hours and usage patterns
Our engineers will design the right compressed air solution for your business – ensuring optimal performance while avoiding costly oversizing.
Diesel vs Electric Compressors
When should I choose diesel over electric compressors?
Choose diesel compressors when:
- No power grid access: Remote construction sites, offshore platforms, marine applications
- Unreliable electricity: Areas with frequent power outages or insufficient electrical capacity
- High mobility needs: Moving between multiple job sites daily
- Backup power situations: When your main electrical compressor is down for maintenance
Most of our marine clients rely on diesel units because ships and offshore platforms often lack sufficient electrical infrastructure for large compressors.
What are the advantages of diesel compressors for offshore and marine work?
Diesel compressors excel in marine environments because:
- Complete independence: No need for shore power or generators
- Higher reliability: Less affected by electrical system failures
- Portable design: Easy to move between vessels and platforms
- Proven durability: Built to withstand harsh marine conditions
VU Technology provides marine-grade air compressor equipment and technical consultation for offshore operations. Our team understands the demanding requirements of marine environments and can recommend suitable compressed air solutions.
How portable are diesel compressors compared to electric units?
Diesel compressors offer superior mobility:
- True portability: No power cord limitations
- Quick setup: Start working immediately at any location
- Multi-site efficiency: Move between job sites without infrastructure concerns
VU Technology’s trailer-mounted units make relocation simple for construction and marine projects.
What support do you provide for diesel compressor projects?
VU Technology offers comprehensive diesel compressor support:
- On-site consultation: We assess your site requirements before recommending equipment
- Quick response: 24/7 urgent support for breakdowns and maintenance
- Rental and sales: Flexible options for short-term and long-term needs

Buy vs Rent Decisions
Should I buy or rent an air compressor?
The decision depends on your project duration and usage pattern:
Consider RENTING when:
- Project duration under 1 month to 3 months
- Testing different compressor sizes for your needs
- Cash flow management is priority
- Backup for maintenance periods
Consider BUYING when:
- Daily operations requiring consistent compressed air
- Multiple ongoing projects spanning 6 months to 12 months
- Long-term cost savings outweigh upfront investment
Many of our marine clients start with rentals to test performance before committing to purchase for their fleet.
What are your rental rates and purchase prices?
We offer competitive pricing for both rental and purchase options:
Rental Options:
- Daily rates available for short-term projects
- Monthly rates for long-term requirements
Purchase Options:
- Competitive pricing on new equipment
- Rent to own

Repair & Maintenance
How often should I service my air compressor?
Regular maintenance extends equipment life and prevents costly breakdowns:
Daily checks:
- Oil levels and air filter condition
- Drain moisture from receiver tanks
- Visual inspection for leaks or unusual sounds
Scheduled maintenance:
- Every 500 hours: Oil changes and filter replacements
- Every 2000 hours: Comprehensive inspection and adjustment
- Annual service: Complete system overhaul and parts replacement
Singapore’s humid climate may require more frequent moisture drainage and filter changes.
