🔧 SELECTING DIESEL COMPRESSOR AIR FLOW ACCORDING TO THE NUMBER OF TOOLS

Choosing a portable diesel compressor is not only about pressure—the compressor must also deliver enough air flow to operate all the tools that will be used simultaneously.

Each pneumatic tool has its own air-consumption requirement, usually measured in CFM or m³/min. To calculate the required compressor capacity:

✅ List every tool that may operate at the same time
✅ Confirm the air consumption of each tool
✅ Add their air-flow requirements together
✅ Allow an additional 20–30% capacity for pressure losses, air leaks and changing demand
✅ Confirm that the compressor can supply the required flow at the correct working pressure

For example, if three tools each require 60 CFM and will operate simultaneously, the combined demand is 180 CFM. Adding a suitable safety margin means selecting a compressor capable of supplying approximately 220–235 CFM at the required pressure.

It is also important to consider how the tools are used. Tools operating intermittently may not require their full combined air demand continuously, while applications such as sandblasting, drilling or production work often require a stable, uninterrupted supply.

An undersized diesel compressor can cause:

❌ Pressure drops
❌ Reduced tool performance
❌ Slower completion times
❌ Excessive compressor loading
❌ Increased fuel consumption and wear

An oversized unit may increase fuel and operating costs unnecessarily. Correct sizing provides reliable performance, better efficiency and longer equipment life.

⚙️ ASC-SPM-2 COMPRESSORS FOR CONTINUOUS 24-HOUR PRODUCTION

When production runs around the clock, your compressed-air system needs to keep pace with changing demand while maintaining reliable and efficient performance.

Airstream’s ASC-SPM-2 two-stage permanent-magnet variable-speed compressors are ideal for demanding industrial environments where compressed air is required throughout multiple shifts.

The two-stage compression process divides the compression workload between two stages, helping to improve operating efficiency and reduce the energy required to produce compressed air. Permanent-magnet variable-speed technology also adjusts the compressor’s output according to actual air demand, helping to minimise unnecessary power consumption during changing production cycles.

Benefits for continuous-production facilities include:

✅ Energy-efficient two-stage compression
✅ Air delivery matched to production demand
✅ Reduced unloading and wasted energy
✅ Stable compressed-air supply
✅ Suitable for demanding industrial applications
✅ Potentially lower lifetime operating costs

For reliable 24-hour operation, the compressor must be correctly sized, professionally installed and supported by a planned maintenance programme. Airstream Compressors can help assess your air demand and recommend the correct solution for your facility.

When should your factory upgrade from single-stage to two-stage ASC-SPM-2 technology?

A single-stage compressor can perform efficiently in many applications—but as production expands and compressed-air demand increases, a two-stage system may offer greater long-term efficiency.

The ASC-SPM-2 uses two compression stages instead of producing the required pressure in one stage. Interstage cooling reduces the temperature of the air before it enters the second stage, helping the compressor reach the required pressure with less energy.

Your factory may benefit from upgrading when:

✅ Compressed-air demand is consistently high
✅ The compressor operates for long periods or continuously
✅ Electricity costs represent a significant portion of operating expenses
✅ Production has expanded beyond the capacity of the current system
✅ More air delivery is required from an appropriately sized compressor
✅ Reducing lifecycle costs has become a priority

Two-stage compression is particularly valuable in larger, high-demand industrial applications where even a modest improvement in efficiency can produce meaningful savings over many operating hours.

However, upgrading should always be based on your actual air demand, operating pressure, production cycle and existing system performance. A compressed-air assessment can help determine whether ASC-SPM-2 technology is the right investment for your factory.

How Two-Stage Compression Improves the Efficiency of ASC‑SPM‑2 Compressors

Producing compressed air requires energy, which is why the way air is compressed can significantly affect the efficiency and operating cost of your system.

Instead of compressing air to the required pressure in one step, the ASC‑SPM‑2 uses two-stage compression. Air is partially compressed during the first stage, cooled, and then compressed to its final pressure during the second stage.

This process offers several important advantages:

✅ Reduced compression work
✅ Lower operating temperatures
✅ Improved compression efficiency
✅ Reduced thermal stress on components
✅ Reliable performance during continuous operation
✅ Potentially lower energy consumption and operating costs

The ASC‑SPM‑2 range combines efficient two-stage compression with permanent-magnet variable-speed technology. The compressor can adjust its output according to changing air demand, helping reduce unnecessary power consumption during periods of lower production.

For facilities with substantial or fluctuating compressed-air requirements, the ASC‑SPM‑2 offers an efficient solution designed to deliver dependable airflow while supporting long-term energy savings.

Choosing the correct compressor size, pressure and configuration remains essential. Airstream Compressors can help assess your application and recommend a solution suited to your actual production requirements.

MATCHING AN ASC-SPM COMPRESSOR’S AIR DELIVERY TO YOUR PRODUCTION CYCLE

Compressed-air demand rarely remains constant throughout the working day. Production start-ups, shift changes, machine cycles and periods of reduced activity can all cause air consumption to rise and fall.

An ASC-SPM Energy-Saving Permanent Magnet Compressor can adjust its air delivery to follow these changing requirements. Instead of continuously producing more compressed air than the plant needs, the compressor varies its operating speed to deliver air according to actual demand.

Correctly matching the compressor to your production cycle can help:

✅ Reduce unnecessary energy consumption
✅ Maintain stable system pressure
✅ Limit inefficient unloaded running
✅ Improve compressor performance during fluctuating demand
✅ Reduce unnecessary wear on system components
✅ Support more reliable and cost-effective production

For the best results, the compressor must be selected according to your actual airflow, operating pressure and production profile. An oversized compressor can still waste energy, while an undersized unit may struggle to maintain pressure during peak demand.

Airstream Compressors can help assess your compressed-air requirements and recommend an ASC-SPM solution suited to your production cycle.

In a multi-compressor system, choosing the correct lead machine can make a significant difference to overall energy efficiency.

An ASC-SPM permanent magnet energy-saving compressor is an excellent choice for the lead role because it can continuously adjust its output to match changing compressed-air demand. Instead of repeatedly loading, unloading or running at full capacity when less air is required, the ASC-SPM varies its motor speed and supplies only the air the system needs.

As the lead compressor, the ASC-SPM can:

✅ Respond to fluctuations in air demand
✅ Maintain more stable system pressure
✅ Reduce unnecessary unloaded running
✅ Limit frequent starting and stopping of other compressors
✅ Allow fixed-speed units to operate efficiently as base-load or support machines
✅ Reduce energy waste across the complete compressor system

During normal production, the ASC-SPM manages variations in demand. When air consumption rises beyond its available capacity, additional compressors can be brought online in a controlled sequence. As demand falls, the support machines can be switched off while the ASC-SPM continues matching the remaining requirement.

For the best results, the compressors must be correctly sized and coordinated through an appropriate control strategy. The ASC-SPM should also operate within its effective control range—because even an energy-saving compressor cannot compensate for poor system design, incorrect sequencing or excessive oversizing.

Let Airstream Compressors help you develop a reliable multi-compressor solution designed around your facility’s actual air demand.

An energy-saving compressor must still be correctly sized to deliver genuine efficiency.

The ASC-SPM range uses Permanent Magnet Variable Speed Drive technology to adjust compressor output according to changing air demand. However, installing a unit that is significantly larger than the application requires can still waste energy.

An oversized compressor may:

Operate continuously near its minimum speed
Run outside its most efficient operating range
Cycle or unload unnecessarily during periods of low demand
Consume more power than a correctly sized unit
Increase the initial purchase and maintenance costs
Make pressure control less stable

Correct sizing requires more than selecting a compressor for the highest possible air demand. Normal consumption, peak demand, operating pressure, duty cycle, future expansion and acceptable pressure drop should all be considered.

A properly selected ASC-SPM compressor can respond efficiently to changing demand while maintaining stable pressure—without carrying unnecessary excess capacity.

Before upgrading your compressed air system, arrange a professional assessment to ensure that the compressor matches the application.
