Saylor-Beall 15 HP Pressure-Lubricated 4500 & 9000 Series

Saylor-Beall 15 HP Pressure-Lubricated 4500 & 9000 Series

The Saylor-Beall 15 HP line represents a major jump in industrial air capacity. At this power level, you choose between two massive, American-made cast iron pumps: the Model 4500 (2-cylinder) and the Model 9000 (4-cylinder). Both are two-stage pumps built for a lifetime of heavy-duty service.

Pump Comparison: 4500 vs. 9000

While both pumps are rated for 15 HP, they differ in output and mechanical design. The Model 9000 is essentially a doubled-up version of the 4500, offering roughly double the air volume.

Lubrication Options

• Splash-Lubricated: The time-tested standard. It uses oil dippers on the connecting rods to splash lubricant throughout the crankcase. This is ideal for standard industrial applications where the unit sits on a level floor.
• Pressure-Lubricated (PL): Designed for extreme duty cycles. A gear-type oil pump forces filtered oil through a rifle-drilled crankshaft directly to the bearings and pins. These models include a spin-on oil filter, making them essential for 24/7 operations or high-heat environments.

Standard vs. Performance Packages

The Standard Package includes the basic industrial essentials: a magnetic starter, manual tank drain, and standard intake filter. The Performance Package (FP) upgrades the unit into a “plug-and-play” industrial station.

Performance Package Features:

• Air-Cooled Aftercooler: Mounted in front of the motor fan to drop discharge temperatures, which forces moisture out of the air before it reaches your tools.
• Automatic Tank Drain: An electric timer drain that automatically purges water from the tank to prevent internal rust.
• Low Oil Level Switch: Protects your investment by shutting down the motor if the oil level drops below a safe limit.
• Quiet Intake Filter: An oversized filter that significantly reduces the noise level of the air intake.
• Vibration Isolator Pads: Heavy-duty pads that minimize vibration transferred to the floor, extending the life of the tank and components.

Summary Recommendation

• Choose the 4500 Series if you need a bulletproof 15 HP compressor for high-demand tools and automotive service.
• Choose the 9000 Series if you are running a large production facility, sandblasting operation, or any application where more is required.
