Schulz SRP 4050 Flex Rotary Screw Air Compressor – 50 HP, Variable Speed, High CFM, 125 PSI, 3 Phase Industrial

DescriptionShort DescriptionUltra high-capacity 50 HP variable-speed rotary screw air compressor designed for industrial applications requiring maximum airflow, energy efficiency, and continuous-duty performance.Full DescriptionThe Schulz SRP 4050 Flex Rotary Screw Air Compressor (Part Numbers: 970.3908-0 / 970.3909-0) is a premium compressed air system engineered for continuous-duty industrial operation, very high airflow demand, and intelligent energy efficiency.Designed for large manufacturing plants, production lines, automotive facilities, CNC operations, and heavy industrial environments, this unit excels in applications where compressed air demand fluctuates throughout the day.Unlike fixed-speed compressors, the Flex series utilizes a frequency inverter (variable speed drive) that automatically adjusts motor speed based on real-time air demand. This advanced control system can reduce energy consumption by up to 38%, stabilize system pressure, and significantly lower operating costs.Higher pressure configurations are available — contact us for more information.Built with rotary screw compression technology, the SRP 4050 Flex delivers smooth, continuous airflow, low vibration, and high reliability. Designed for 24/7 continuous operation, it ensures maximum uptime in demanding industrial environments.This model features a 50 HP three-phase TEFC IP55 motor, providing exceptional durability, efficiency, and long service life under heavy-duty industrial use.The unit can be configured as base-mounted, tank-mounted, or as a total solution (tank dryer filtration), allowing flexible installation depending on your system requirements.Housed in a fully enclosed acoustic cabinet, the compressor operates quietly (approximately 70 dBA) while protecting internal components. Its advanced microprocessor controller and inverter system provide real-time monitoring, diagnostics, and optimized operation.�� User Manuals�� Download the Technical Manual: http://schulzaircomp.com/wp-content/uploads/2026/04/4000_FLEX.pdf�� Download the Controller Manual: http://schulzaircomp.com/wp-content/uploads/2024/03/CONTROL-123-E-NET.pdfApplicationsLarge industrial manufacturing Full production lines Automotive and heavy equipment facilities Laser cutting and CNC systems High-demand pneumatic systemsKey BenefitsVariable speed (inverter) technology for energy savings Up to 38% lower energy consumption Ultra high airflow output for demanding applications Maximum pressure of 125 PSI Higher PSI options available (call for details) Stable system pressure (no fluctuation) Reduced operating costs Quiet and smooth operation Advanced electronic monitoring systemSpecificationsPart Number: 970.3908-0 Voltage: 208–230V / 3 PhasePart Number: 970.3909-0 Voltage: 460V / 3 PhaseModel: SRP 4050 Flex Compressor Type: Rotary Screw (Oil-Lubricated, Variable Speed)Airflow: Variable output (model-dependent) Max Pressure: 125 PSI (higher PSI available upon request)Motor: 50 HP (37 kW) Drive Type: Frequency Inverter (Variable Speed)Tank Capacity: ~132 Gallons (optional integrated) Discharge Size: 1” Outlet Cooling: Air-CooledNoise Level: ~70 dBAWeight: Approx. 1,050 kg (≈ 2,300 lbs) Dimensions: Similar to SRP 4000 Flex Series (varies by configuration)WarrantyStandard Warranty Coverage2-Year Warranty on Airend (Pump)1-Year Warranty on Complete Unit (motor, electrical components, controls, and all other parts)Extended Warranty AvailableOptional extended warranty plans are available for additional coverage and long-term protection.
