Atlas Copco TC-4000-S-ES
Product Introduction:
The TC-4000-S-ES is a large-capacity towable air compressor delivering 4,000 CFM of free air. The “S” denotes single-stage compression, and “ES” denotes electric drive. This unit is designed for high-volume applications such as large-scale construction, mining, and industrial plants requiring continuous, high-flow compressed air with electric power availability.
Detailed content
Technical Specifications:
- Free Air Delivery (FAD): 4,000 CFM (113.3 m³/min) at 100 PSI (7 bar)
- Maximum Working Pressure: 175 PSI (12 bar)
- Drive Type: Electric Motor — 315 kW (422 HP)
- Power Supply: 400V / 50Hz / 3-phase (or 480V / 60Hz / 3-phase per region)
- Compression Stages: Single-Stage (S)

Material Composition:
- Frame: High-strength welded steel with hot-dip galvanizing
- Air End: Cast iron rotary screw — single-stage, oil-flooded
- Tank: ASME / PED certified carbon steel pressure vessel
- Aftercooler: Aluminum plate-fin construction
- Canopy: Galvanized steel with acoustic insulation
Structural Characteristics:
- Tandem-axle trailer with hydraulic jacks for leveling
- Full-width rear service platform with anti-slip grating
- Dual kingpin for towing stability
- Integrated circuit breaker panel and motor starter
Working Principle:
Electric motor drives a single-stage rotary screw air end. Ambient air is filtered, compressed in one stage to the target pressure, then routed through an air-cooled aftercooler to reduce discharge temperature before delivery. The single-stage design produces higher discharge temperatures than two-stage units, making it best suited for applications where air temperature is not critical.
Advantage Highlights:
- Highest flow rate in the TC-4000 family at the lowest capital cost
- Electric drive eliminates fuel cost and exhaust emissions
- Simple single-stage design reduces maintenance complexity
- Road-towable — easy relocation between job sites
Applicable Industries:
Large-scale construction, concrete batching, quarrying, power generation, shipbuilding, steel fabrication, paint shops
Model Series: TC-4000 Series — Towable Compressors (4,000 CFM class)
Installation Requirements:
- 400V/480V 3-phase power supply with minimum 500A capacity
- Level, compacted surface capable of supporting 6,800 kg
- Minimum 3-meter clearance on all sides for airflow
Usage Precautions:
- Single-stage discharge temperature is high — do not use for sensitive pneumatic tools requiring cool air
- Verify power supply capacity before startup; voltage drop below 380V will trigger motor protection
- Clean aftercooler fins weekly in dusty environments
- Change compressor oil every 4,000 hours or annually
