Rolair 15 & 20 HP Two-Stage Stationary Compressors

Rolair 15 & 20 HP Two-Stage Stationary Compressors

Rolair 15 & 20 HP Two-Stage Stationary Compressors are the ultimate heavy-industrial power plants. Designed for facilities that operate on a massive scale—such as large-scale manufacturing plants, industrial sandblasting operations, and high-volume pneumatic automation—these units provide an unrelenting flow of high-pressure air (175 PSI) designed for 100% duty-cycle environments.

Featuring the massive K60 and the extreme-displacement K100 pumps, these compressors represent the pinnacle of reciprocating technology, offering air volumes that rival small rotary screw units while maintaining the simplicity and serviceability of a piston design.

The 15 HP Series: Industrial High-Volume

The 15 HP models are designed for facilities where multiple high-demand tools or automated systems are running 24/7. These units require Three-Phase (153) power to operate their high-torque industrial motors.

• K60 Pump Options: The four-cylinder K60 provides a proven, high-efficiency platform for sustained industrial use.
  • H15312K60: 120-gallon horizontal configuration.
  • H15320K60: 200-gallon horizontal tank for maximum air storage.
• K100 Pump Options: The K100 is an “extreme-displacement” pump designed for the most air-hungry applications.
  • H15312K100: 120-gallon horizontal configuration.
  • H15320K100: 200-gallon horizontal tank for the largest possible air reserve.

The 20 HP Series: Maximum Reciprocating Power

The 20 HP series is the most powerful reciprocating lineup offered by Rolair. By pairing a 20 HP three-phase motor with the massive K100 pump, these units deliver the highest CFM available in a piston compressor.

• Models: H20312K100 (120-gallon) and H20320K100 (200-gallon).
• Performance: These units are engineered for the most grueling tasks, such as running multiple large-scale sandblast nozzles or high-capacity industrial rock drills.
• Storage: We highly recommend the 200-gallon horizontal tank for 20 HP models to act as a massive heat sink and storage reservoir, ensuring stable line pressure during peak demand.

Extreme-Duty Engineering Features

• Multi-Cylinder Cast-Iron Pumps: Both the K60 and K100 pumps feature 100% cast-iron construction. The K100’s massive crankcase and cylinders are designed to dissipate heat rapidly during 24/7 operation.
• Two-Stage Intercooling: High-capacity, finned copper intercoolers significantly reduce the air temperature between the first and second stages. This ensures cooler air enters the receiver, reducing moisture and increasing efficiency.
• Oversized Flywheels: Designed to move a massive volume of cooling air over the pump cylinders while providing the inertia needed for smooth, low-vibration operation.
• Industrial Drive Systems: Multiple B-section V-belts ensure maximum power transfer from the motor to the pump with zero slippage, even under full-load startups.
• ASME & OSHA Compliant: All models feature American-made, ASME-certified tanks and totally enclosed steel belt guards for maximum operator safety.
