Jenny Two-Stage Base Mount Compressors

Jenny Two-Stage Base Mount Compressors

Jenny Two-Stage Base Mount Compressors are the industrial standard for high-pressure pneumatic power. Designed for permanent installation into existing air systems, service truck bodies, or custom industrial layouts, these “pump-and-motor” assemblies deliver the massive volume and consistent 175 PSI required for heavy-duty applications.

By utilizing a two-stage compression process with dedicated intercooling, these units operate more efficiently and produce cooler air than single-stage alternatives, making them the preferred choice for 100% duty-cycle environments.

The GT & W Series (2 HP to 5 HP)

These models are designed for commercial automotive shops, small manufacturing plants, and high-pressure service vehicle integration.

• GT2B-B & GT3B-B (2 HP & 3 HP): Utilizing the efficient “G” two-stage pump, these are ideal for high-pressure tasks in smaller footprints.
• W3B-B (3 HP): Features the larger displacement “W” pump, offering superior cooling and a slower RPM for extended service life.
• GT5B-B & W5B-B (5 HP): The industry standard for 5 HP industrial air. The W5B-B is the heavy-duty choice for continuous-use shops.

The U-Series (7.5 HP to 10 HP)

The U-Series marks the transition into heavy industrial power. These units are built to run entire shops, powering multiple 1-inch impact wrenches, sandblasters, and CNC machinery simultaneously.

• U75B-B (7.5 HP): A robust industrial assembly for medium-to-large facilities.
• U10B-B (10 HP): Maximum power on the “U” pump platform, delivering massive CFM for high-production environments.

The T-Series (15 HP to 25 HP)

The T-Series represents the pinnacle of reciprocating compressor technology. These are “Large-Frame” industrial plants designed for the most grueling heavy-industrial applications, such as large-scale manufacturing, rock quarrying, and massive maintenance facilities.

• T15B-B (15 HP): Heavy-duty four-cylinder configuration for large-scale air demands.
• T20B-B (20 HP): Extreme-output assembly for 24/7 industrial operations.
• T25B-B (25 HP): The flagship model, providing the highest possible air volume in the Jenny reciprocating lineup.

Engineering Excellence: The Two-Stage Advantage

• 175 PSI Maximum Pressure: The two-stage design allows for significantly higher pressure than single-stage units, essential for high-torque tools and long piping runs.
• Cast-Iron Construction: Every pump features a splash-lubricated cast-iron crankcase and cylinders. This “over-built” philosophy ensures the pump remains rebuildable for decades.
• High-Efficiency Intercooling: Large, finned copper intercoolers dissipate heat between the first and second stages, cooling the air before it reaches the second cylinder to increase volumetric efficiency.
• Precision Balanced Flywheel: Directs a massive volume of air over the pump and intercoolers while ensuring vibration-free operation on your mounting surface.
• Industrial Motors: Equipped with premium-grade motors designed for high-starting torque and continuous duty in harsh industrial climates.

Technical Selection Guide

Installation Note: All base-mount units must be installed on a level, solid foundation (such as a steel base plate or concrete pad) with vibration isolation mounts. These high-performance units require properly sized electrical service and external air receivers that meet ASME standards for high-pressure storage.
