Technical Specifications:

• FAD: 4.0 m³/min (141 CFM)
• Max Working Pressure: 16 bar (232 psi) / 25 bar (363 psi)
• Motor Power: 37 kW (50 HP) electric (PB = boosted motor)
• Cooling: Water-cooled
• Sound Level: 78 dB(A)
• Weight: ~1,350 kg
• Dimensions: ~2,100 × 1,000 × 1,350 mm

Material Composition:

• Cylinders: Cast iron, nickel-chrome plated
• Piston rings: Carbon-filled PTFE
• Frame: Reinforced steel, epoxy-coated
• Aftercooler: Stainless steel tube-in-tube, water-cooled

Structural Features:

• PB = Power Boost — upgraded motor and frame for continuous duty
• Two-stage oil-free compression
• Water-cooled aftercooler (stainless steel)
• Heavy-duty skid with integrated drain valve
• Forklift pockets + lifting eyes

Working Principle:
Two-stage oil-free piston compression. PB motor delivers 37 kW for sustained high-pressure output. Water-cooled stainless steel aftercooler ensures consistent discharge temperature even at 25 bar. Class 0 air quality maintained throughout.

Key Advantages:

• 25 bar at 4 m³/min — unique high-pressure/high-flow combination
• PB motor rated for 100% duty cycle at 25 bar
• Stainless steel aftercooler resists corrosion
• Water-cooled for thermal stability

Applicable Industries:
High-pressure painting, hydrostatic testing, PET blow molding, fire suppression systems, scuba diving stations, CNC high-pressure coolant.

Installation Requirements:

• Reinforced floor (1,350 kg)
• Water: 12 L/min, max inlet 30°C
• Electrical: 400V/50Hz/3-phase, 63A
• Indoor or weather-protected outdoor

Usage Notes:

• At 25 bar, limit continuous runtime to 4 hours per 8-hour shift
• Use only Atlas Copco genuine water-cooled aftercooler
• Inspect cylinder head gaskets every 4,000 hours
• PB motor requires 400V supply — do not use with 230V
