What CFM and PSI does this compressor deliver?

This Industrial Series compressor delivers 22.0 CFM at 0 PSI and 17.5 CFM at its maximum working pressure of 175 PSI. The two-stage cast iron pump design maximizes air output efficiency while operating at a quiet 767 RPM. This CFM rating handles demanding pneumatic applications including spray guns, sanders, impact wrenches, and multiple smaller tools running simultaneously. The 175 PSI maximum pressure provides the power needed for heavy-duty industrial applications while the substantial air flow rate ensures consistent tool performance during extended use cycles. The two-stage compression process generates cooler, drier air compared to single-stage units, which translates to better tool performance and longer equipment life. With an 80-gallon tank capacity, you get sustained air delivery that maintains pressure during high-demand applications. Forge Claw offers multiple financing options for qualified buyers.

What air tools can I run with this compressor?

This 17.5 CFM compressor handles virtually all pneumatic tools used in professional applications. You can operate spray guns for automotive painting and coating work, sanders and grinders for surface preparation, impact wrenches up to 1-inch drive, nail guns and staplers for construction work, and plasma cutters for metal fabrication. The substantial air flow supports multiple smaller tools running simultaneously or single high-demand tools like die grinders and cut-off tools. Agricultural applications include powering pneumatic seed meters, hydraulic tool operation, and shop equipment for equipment maintenance. The 175 PSI maximum pressure provides sufficient power for air chisels, concrete breakers, and other heavy-duty demolition tools. The 80-gallon tank capacity means you can run air-hungry tools continuously without pressure drops that affect performance. The two-stage design delivers consistent pressure for precision work while handling the sustained demands of production environments.

Is this compressor portable enough for job sites?

This is a stationary compressor designed for permanent shop installation rather than job site mobility. The vertical 80-gallon tank configuration with four-leg stability base minimizes floor space requirements but the unit weighs approximately 400-500 pounds when fully assembled. It requires 230V single-phase power with a 30A breaker, making it ideal for established shop environments, manufacturing facilities, and permanent service bays. The vertical design maximizes air storage while fitting into tighter spaces compared to horizontal tank configurations. For contractors needing portable compressed air, this unit works well in semi-permanent installations like construction trailers or service trucks with proper electrical supply. The robust construction and low-RPM operation make it suitable for indoor environments where noise control matters. If you need true job site portability, consider smaller wheeled units, but for maximum air storage and continuous-duty performance in a fixed location, this Industrial Series compressor delivers professional reliability.

What maintenance does this compressor require?

Regular maintenance keeps this cast iron pump compressor running reliably for years. Check and change the pump oil every 500 operating hours or annually using the sight glass level indicator for monitoring. Replace the automotive-style paper air filter element every 3-6 months depending on operating environment dust levels. Drain the tank daily or after each use session to remove moisture that naturally accumulates during compression. The centrifugal unloader requires periodic inspection to ensure proper loadless startup operation. Check belt tension monthly and inspect for wear, adjusting or replacing as needed. Examine copper or stainless braided discharge tubing connections for leaks during routine inspections. The tapered roller bearings are designed for long service life but should be monitored for unusual noise or vibration. Keep the motor cooling fins clean and verify proper electrical connections remain tight. The ASME safety valves should be tested annually to ensure proper pressure relief operation. Following these maintenance intervals maximizes the compressor's service life and maintains optimal performance.

How does tank size affect how long I can run tools continuously?

The 80-gallon tank capacity significantly extends continuous tool operation compared to smaller tanks. Tank size determines how much compressed air you have stored for immediate use before the pump must cycle on to refill. With 80 gallons of storage at 175 PSI, you can operate air-hungry tools longer between pump cycles, maintaining consistent pressure for better tool performance. For example, a spray gun requiring 10 CFM can run approximately 8-10 minutes from tank storage alone before pressure drops require pump operation. Multiple smaller tools like nail guns or sanders can operate for extended periods with minimal pump cycling. The large tank capacity particularly benefits applications with intermittent high air demand followed by idle periods, allowing the pump to refill during downtime. This reduces motor cycling frequency, extending equipment life while providing steady air pressure for precision work. Continuous-duty applications benefit from the combination of 17.5 CFM pump output and substantial tank storage, ensuring tools maintain optimal operating pressure even during sustained use periods common in production environments.
