ODM 15 Hp Rotary Screw Compressor Manufacturers & Factory

A premium-engineered 15 HP (11 kW) rotary screw compressor generates approximately 55 to 65 CFM (1.55 to 1.85 m³/min) at standard 8 bar (116 PSI) operating pressure. Operating at higher pressures such as 10 bar (145 PSI) yields approximately 50 to 54 CFM, while high-pressure 13 bar (188 PSI) configurations deliver around 42 to 46 CFM. Volumetric flow depends heavily on airend rotor tolerances, motor efficiency ratings (IE3 vs IE4/IE5 PM), and ambient air intake conditions.

Fixed-speed compressors operate on a load/unload control cycle: once cut-out pressure is reached, the motor continues spinning unloaded while consuming 25% to 40% of its rated electrical power without producing any useful air. A 15 HP Permanent Magnet Variable Frequency Drive (PM VFD) dynamically slows the motor speed to precisely mirror real-time CFM consumption. When air demand drops to zero, the motor stops completely, saving between 20% and 40% on cumulative monthly electrical bills and preventing electrical grid spikes via soft-start operation.

For standard industrial setups, a good baseline formula for rotary screw compressors is 120 to 150 liters of tank buffer per cubic meter per minute of compressor capacity. For a 15 HP system (producing ~1.65 m³/min), an air receiver tank between 300 Liters and 500 Liters (80 to 130 US gallons) is recommended. If your shop utilizes sharp intermittent surges (e.g., massive abrasive blasting nozzles or giant pneumatic presses), upsizing to a 1,000-liter storage buffer prevents artificial line pressure drops.

The initial break-in inspection occurs at 500 operating hours to replace the initial oil filter and clean the intake suction screen. Following break-in, routine scheduled intervals are established every 2,500 to 3,000 running hours (or annually, whichever comes first). This involves renewing the synthetic rotary screw fluid, spin-on spin-off oil filter element, primary cellulose air intake cartridge, and internal air-oil separator element to preserve residual oil carryover below 2-3 ppm.

An 11 kW (15 HP) motor draws approximately 23–25 Full Load Amps (FLA) on a 380V/3-phase/50Hz system, and roughly 38–42 Amps on a 220V/3-phase/60Hz line. Due to our integrated Inovance/VFD soft-starters, inrush starting current is limited to 1.0x rated load current, eliminating the 6x–8x amp spikes typical of direct-online (DOL) piston compressors. This permits smaller upstream circuit breakers and reduced line transformer overhead.
