Atlas Copco TC-4000-S
Product Category: Towable Mobile Air Compressor — Single-Stage Compression
Product Introduction:
The TC-4000-S is a single-stage towable compressor delivering 4,000 CFM. The “S” denotes single-stage compression. This is the most cost-effective configuration in the TC-4000 series, suitable for high-volume applications where discharge air temperature is not a critical factor. Drive type and enclosure options vary by regional configuration (commonly electric or diesel).
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: Varies by configuration — commonly Electric Motor 315 kW (422 HP) or Diesel Engine 350 kW (469 HP)
- Power Supply (Electric): 400V / 50Hz / 3-phase
- Compression Stages: Single-Stage (S)

Material Composition:
- Frame: Welded structural steel with anti-corrosion coating
- Air End: Cast iron single-stage rotary screw
- Tank: ASME / PED certified carbon steel — 450-liter capacity
- Aftercooler: Aluminum plate-fin — air-cooled
- Trailer: Galvanized steel chassis
Structural Characteristics:
- Tandem-axle trailer with hydraulic leveling jacks
- Full-width rear service platform
- Integrated control panel with analog gauges and digital hour meter
- Forklift pockets on all four sides
Working Principle:
Electric motor or diesel engine 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. The single-stage process produces higher discharge temperatures (approximately 160°C) compared to two-stage units. Compressed air exits through a moisture separator and delivery connection.
Advantage Highlights:
- Lowest capital cost in the 4,000 CFM class
- Simplest design — fewest components to maintain
- Highest flow rate per unit of investment
- Suitable for applications where air temperature is not critical (rock drilling, jackhammering, general construction)
Applicable Industries:
Rock drilling, jackhammer operations, general construction, concrete batching, bulk pneumatic tool operations, quarry blasting
Model Series: TC-4000 Series — Towable Compressors (4,000 CFM class) — Single Stage
Installation Requirements:
- 400V 3-phase supply (electric) with minimum 500A capacity, or diesel fuel supply
- Level, compacted surface — minimum 6,500 kg load capacity
- 3-meter clearance on all sides for airflow
Usage Precautions:
- Do not use for paint spraying, food-grade air, or sensitive pneumatic instruments — discharge temperature of 160°C will damage coatings, contaminate product, and reduce tool life
- Install an additional aftercooler if cooler air is required
- Change compressor oil every 4,000 hours
- Monitor discharge temperature gauge — do not exceed 175°C
