Model Series: P-Series (PF Series) Portable Compressors

Technology Type: Diesel-driven rotary screw air end

Free Air Delivery (FAD): 4000 cfm (113 m³/min)

Working Pressure Range: 7 – 13 bar (100 – 185 psi)

Engine: Diesel engine, heavy-duty continuous-rated

Fuel Tank Capacity: Approximately 400 – 500 liters

Cooling System: Water-cooled with heat exchanger; HW-rated

Noise Level: Approximately 95 – 98 dB(A) at 7 meters (open frame configuration)

Dimensions (L × W × H): Approximately 5200 × 2100 × 2400 mm

Weight: Approximately 6500 – 7500 kg (operating weight)

Structure: Trailer-mounted chassis with open or basic canopy (no PN/DN enclosure)

Air Receiver Volume: Approximately 800 – 1000 liters

Drive System: Direct diesel-to-screw drive

Control System: Electronic pressure controller with engine and compressor parameter monitoring

Key Features:

• Highest capacity in the standard (non-G, non-PN/DN) PF4000 line
• HW-rated for operation in temperatures up to 50°C and high humidity
• Open-frame design allows maximum airflow for engine cooling
• Simple, rugged construction for heavy-duty environments
• Easy access to all service points

Advantages:

• Maximum airflow at lowest configuration cost
• Open frame provides best engine cooling in extreme heat
• Proven reliability in mining and quarrying
• Straightforward maintenance with minimal components

Applicable Industries: Mining, quarrying, large civil construction, road building, aggregate production, rental fleets

Installation Requirements: Level surface; adequate exhaust clearance (minimum 5 meters); no special electrical connection required for basic model; heavy-duty towing vehicle required

Usage Notes: Open-frame configuration generates higher noise — use hearing protection; in dusty environments, clean aftercooler and air filter daily; HW rating eliminates derating but monitor coolant temperature in sustained full-load operation
