Atlas Copco TC-4000-P-PB-ES
Product Introduction:
The TC-4000-P-PB-ES is a two-stage, electric-driven towable compressor housed in a full protective (PB) canopy. The “PB” designation indicates a weather-protected, sound-attenuated enclosure that shields all components from rain, dust, wind, and debris. This configuration is intended for outdoor deployment in harsh environmental conditions where open-frame units would suffer accelerated wear.

Material Composition:
- Frame: Hot-dip galvanized structural steel
- Canopy (PB): 1.5 mm galvanized steel with 50 mm acoustic insulation (rock wool)
- Air End: Cast iron two-stage rotary screw
- Tank: ASME / PED certified carbon steel — 500-liter capacity
- Aftercooler: Aluminum plate-fin — mounted inside PB enclosure
Structural Characteristics:
- Tandem-axle trailer with full PB canopy covering entire unit
- Air intake and exhaust routed through canopy with weather baffles
- Lockable access doors on both sides for maintenance
- Integrated lighting inside canopy for nighttime service
Working Principle:
Identical to TC-4000-P-ES in compression process. The PB canopy creates a controlled micro-environment: intake air is drawn through elevated, weather-protected filters; compressed air is cooled inside the enclosure; discharge air exits through a weather-sealed outlet. The enclosure protects all components from direct rain, UV exposure, and particulate ingress.
Advantage Highlights:
- Extended component life in outdoor/harsh environments — reduces maintenance cost by 30–40%
- 10–12 dB noise reduction improves compliance with occupational noise regulations
- Weather protection allows year-round outdoor storage without degradation
- Higher-grade filtration possible due to protected intake — improves air quality
Applicable Industries:
Outdoor construction, mining, quarrying, pipeline work, military field operations, events, remote industrial sites
Model Series: TC-4000 Series — Towable Compressors (4,000 CFM class) — Protected Variant
Installation Requirements:
- 400V/480V 3-phase supply — minimum 500A
- Level, compacted ground — PB canopy adds approximately 500 kg to operating weight
- Ensure canopy ventilation panels are not obstructed — minimum 0.5-meter clearance at intake and exhaust
Usage Precautions:
- Do not seal canopy completely — ventilation is required for cooling
- Inspect canopy weather seals quarterly; replace if cracked or compressed
- Clean intake filters weekly in dusty outdoor environments
- PB canopy interior temperature can exceed ambient by 10°C — monitor motor temperature in hot climates
