Compressed air is one of the most essential utilities in workshops, garages, fabrication units, and manufacturing plants. Among the various compressor designs available, the trolley mounted air compressor stands out for its mobility, flexibility, and practical performance.
Air Master Engineers manufactures a complete range of trolley mounted air compressors from 1 HP to 15 HP and above, engineered for reliable air delivery, durability, and industrial efficiency. This detailed guide covers specifications, applications, working principles, and complete HP configurations.
What is a Trolley Mounted Air Compressor?
A trolley mounted air compressor is a portable compressed air system installed on a heavy-duty wheeled frame. The integrated trolley structure allows easy movement across different work areas without permanent installation.
Unlike stationary compressors, these units provide:
- Mobility across shop floors
- Reduced installation complexity
- Space-saving design
- Flexible positioning
- Easy relocation between work zones
They are commonly used in automotive workshops, construction sites, engineering units, and on-site service operations.
Working Principle
Most trolley mounted compressors operate on the reciprocating principle.
- The electric motor drives the crankshaft.
- The piston moves inside the cylinder.
- Air is drawn through the inlet valve.
- The piston compresses the air.
- Compressed air is stored in the receiver tank.
The stored air is then supplied through a regulated outlet for pneumatic tools and equipment.
Complete HP Range and Technical Specifications
Air Master Engineers manufactures the following standard HP models:
| HP | Working Pressure (Bar) | Tank Capacity (Litres) | Approx. Air Delivery (CFM)* | Power Phase | Typical Usage |
|---|---|---|---|---|---|
| 1 HP | Up to 8 Bar | 30 – 50 L | 3 – 4 CFM | Single Phase | Inflation, light maintenance |
| 2 HP | 8 – 10 Bar | 50 – 70 L | 6 – 8 CFM | Single Phase | Two-wheeler garages |
| 3 HP | Up to 10 Bar | 70 – 100 L | 8 – 12 CFM | Single / Three | Car workshops |
| 5 HP | 10 – 12 Bar | 120 – 200 L | 14 – 18 CFM | Three Phase | Service stations |
| 7.5 HP | Up to 12 Bar | 200 – 250 L | 20 – 25 CFM | Three Phase | Fabrication units |
| 10 HP | 12 Bar | 250 – 300 L | 28 – 35 CFM | Three Phase | Industrial workshops |
| 12.5 HP | Up to 12 Bar | 300+ L | 35 – 40 CFM | Three Phase | Heavy-duty applications |
| 15 HP | 12 Bar or Custom | 300+ L | 40+ CFM | Three Phase | Continuous industrial use |
*Air delivery may vary depending on configuration and operating conditions.
Custom-built models with higher pressure or CFM requirements are also available.
