Rolair Single-Stage Stationary Compressors

Rolair Single-Stage Stationary Compressors are the definitive choice for professional woodshops, automotive garages, and small industrial facilities. Built around heavy-duty, splash-lubricated cast-iron pumps, these units are designed for 100% duty cycles and decades of service. Whether you require a space-saving vertical tank or a traditional horizontal configuration, Rolair provides a stable, high-output air source that outperforms consumer-grade alternatives.

The 1.5 HP to 2 HP Series (K17 Pump)

These models are optimized for 115V or 230V single-phase power, making them ideal for high-end residential shops and light commercial use. They utilize the K17 pump, famous for its smooth operation and reliability.

• 1.5 HP Models (H151 / V151): Efficient power for steady pneumatic tool use.
• 2.0 HP Models (H2 / V2): Increased CFM for faster recovery in busier environments.
• Tank Options: Available in 30-gallon or 60-gallon capacities.

The 3 HP Series (K18 Pump)

Moving up to the K18 pump provides a significant boost in air volume. These units are designed for shops running more demanding tools like sanders, impact wrenches, and paint sprayers.

• Single-Phase (31): Standard 230V single-phase power.
• Three-Phase (33): Designed for industrial facilities with 230V or 460V three-phase power (marked with *).
• Performance: Features a larger stroke and bore for maximum single-stage CFM.

Core Engineering Excellence

• Cast-Iron Pumps: Every model features a 100% cast-iron pump with a splash-lubricated crankcase and cast-iron cylinders to ensure superior heat dissipation.
• Low-RPM Operation: Rolair stationary units are engineered to run at lower speeds. This reduces vibration, lowers the decibel level in your shop, and significantly extends the life of the motor and pump.
• Industrial Motors: Equipped with heavy-duty, open drip-proof (ODP) motors with thermal overload protection.
• Swedish Steel Valves: High-grade stainless steel reed valves provide maximum volumetric efficiency and durability.
• ASME Certified Tanks: All tanks are American-made and ASME certified, featuring a durable powder-coated finish.

Choosing Your Configuration

Vertical (V-Series)

Best For: Shops where floor space is at a premium. The vertical footprint allows you to tuck the compressor into a corner or between workbenches while maintaining full access to the drain valve and controls.

Horizontal (H-Series)

Best For: Installations under shelving or in low-clearance areas. The horizontal design provides a lower center of gravity and is often preferred in automotive bays for its stability.

Quick Comparison Guide

Note for Three-Phase Models (*): Please specify your voltage requirements (208-230V or 460V) when ordering to ensure the motor and starter are properly configured for your facility.

The 5 HP High-Output Series

These models feature larger, multi-cylinder pumps and high-torque motors to handle rigorous shop environments where air demand is constant.

Three-Cylinder High Displacement (PT03 Pump)

• V5160PT03X: This unique unit utilizes a three-cylinder single-stage pump. By spreading the workload across three cylinders, the unit dissipates heat more effectively and delivers a massive 16 CFM @ 100 PSI, making it one of the most powerful single-stage options available.

The K24 High-Pressure Series (175 PSI)

The K24 series introduces a high-pressure configuration, factory-set at 145-175 PSI. This higher pressure range is essential for shops running heavy-duty truck tire changers or high-torque 1-inch impact wrenches.

• Vertical Models (Space Savers):
  • V5160K24XB: 5 HP motor paired with a 60-gallon vertical tank.
  • V5180K24XB: The ultimate vertical power plant, featuring an 80-gallon tank for the largest air reserve in its class.
• Horizontal Models:
  • H5130K24XB: A compact 30-gallon horizontal unit, perfect for mounting under workbenches.
  • H5160K24XB: 60-gallon horizontal tank for facilities that prefer a low center of gravity.

Industrial Grade Components

• Premium Cast-Iron Construction: Like the smaller models, these feature 100% cast-iron cylinders and crankcases. However, the K24 and PT03 pumps are significantly larger, featuring oversized cooling fins and higher oil capacities for continuous-duty operation.
• Advanced Valve Technology: These models use Swedish Lamellar reed valves, which provide superior airflow and higher heat resistance compared to standard spring-loaded valves.
• Enhanced Drive Systems: All 5 HP models utilize multiple V-belt drives to transfer power more efficiently and reduce belt slippage under heavy loads.
• Safety & Compliance: Every unit comes standard with a totally enclosed steel belt guard and ASME-certified tanks, ensuring a safe work environment that meets strict OSHA standards.

Technical Selection Guide

Installation Note: Due to the high amperage draw of these 5 HP motors, we recommend a dedicated 30-amp circuit for single-phase (230V) models. Ensure your facility’s electrical service is sufficient to handle the startup load of these high-performance machines.
