The NorthStar PK5020N puts a substantial 20-gallon tank to work in a compact horizontal design, but its limits matter as much as its capacity. We’ll examine its 2 HP dual-voltage motor, airflow, pump construction, and practical handling to see how well it suits tire inflation and intermittent tool use. Its 90 PSI maximum may shape that verdict more than the tank size suggests.
Key Takeaways
- The NorthStar PK5020N has a 20-gallon horizontal tank and a compact, low profile for shop storage.
- Its 2 HP dual-voltage motor runs on compatible 115V or 230V circuits.
- It delivers 5.0 CFM at 90 PSI and 6.0 CFM at 40 PSI, with a 90 PSI maximum.
- A cast-iron, two-cylinder pump, crankshaft ball bearings, and cooling components support durable operation.
- It suits inflation and intermittent shop tasks, but its 207-pound weight and limited output constrain portability and continuous high-demand use.
20-Gallon Horizontal Tank
The NorthStar PK5020N’s 20-gallon horizontal tank provides a portable shop-air supply for pneumatic tools. Its layout keeps the tank low and elongated, helping us position the compressor beneath work surfaces or along a shop wall. This Space saving footprint can preserve room for equipment and movement in compact work areas.
At 207 pounds, the unit isn’t lightweight, so we should plan its placement before use rather than treat it as easy to carry. The horizontal profile supports tank stability when the compressor rests on a level surface. Its 43-by-22-by-30-inch dimensions also help us assess clearance and storage needs before choosing a location.
Detailed features
Beyond its 20-gallon tank, the NorthStar PK5020N combines a 2 HP dual-voltage induction motor with a two-cylinder, single-stage cast-iron pump. Its Dual Voltage Motor runs on 115 or 230 volts, drawing 15 or 7.5 amps, respectively, so we can match the supply to the available circuit.
The pump delivers 5.0 CFM at 90 PSI and 6.0 CFM at 40 PSI, with a maximum pressure of 90 PSI. For Cooling System Design, copper-finned intercooler and aftercooler components dissipate heat and reduce moisture.
Ball bearings support both sides of the crankshaft, while maintenance-friendly access simplifies routine service. The unit weighs 207 pounds and measures 43 by 22 by 30 inches.
Pros and Cons
We’ll weigh the PK5020N’s cast-iron pump, dual-voltage motor, and cooling system against its 90 PSI limit and 207-pound weight.
These specifications shape its suitability for shop-air and pneumatic-tool use. Let’s examine the practical pros and cons.
Pros
With its 20-gallon tank and 5.0 CFM output at 90 PSI, the NorthStar PK5020N offers a practical balance of air capacity and portability for shop work and pneumatic tools. We can use its 6.0 CFM delivery at 40 PSI for tasks requiring greater airflow at lower pressure.
The 2 HP dual-voltage induction motor supports 115V or 230V connections, while the two-cylinder cast-iron pump and crankshaft ball bearings contribute to durable construction. Copper-finned intercooler and aftercooler support cooling performance and moisture reduction.
At 207 pounds, the horizontal tank remains movable around a workshop, and maintenance-friendly access simplifies routine service.
Cons
Although the NorthStar PK5020N suits many shop tasks, its limits may rule it out for some setups: the 90 PSI maximum pressure and 5.0 CFM at 90 PSI won’t meet the needs of tools requiring higher pressure or airflow.
At 6.0 CFM and 40 PSI, it supports lighter-demand applications better than sustained, high-consumption work. Electrical setup also requires planning: the 2 HP motor draws 15 amps at 115V or 7.5 amps at 230V, so we’ll need a compatible circuit.
At 207 pounds, it presents portability concerns despite its portable-tank design; moving it between work areas may require assistance.
Concluding thoughts
For shop tasks that need steady air at moderate pressure, the NorthStar PK5020N combines a 2 HP dual-voltage motor, a durable cast-iron pump, and a 20-gallon tank in a portable horizontal design. Its two-cylinder pump delivers 5.0 CFM at 90 PSI, with copper-finned cooling to manage heat and moisture.
We’d consider it for tire inflation, intermittent pneumatic-tool use, and general workshop duties, while matching airflow to each tool’s requirements. For Long Term Reliability, its cast-iron construction and crankshaft ball bearings are useful strengths, though routine maintenance remains essential.
Ideal Applications are jobs that value portable shop air over high-volume, continuous output.
Frequently Asked Questions
What Power Outlet Is Required for the Northstar PK5020N?
Choose an Outlet voltage of 115V or 230V; we recommend matching your available supply. The compressor draws 15 amps at 115V or 7.5 amps at 230V, so make sure your circuit amperage supports the selected configuration.
Can This Compressor Run Continuously Without Overheating?
We can’t confirm continuous operation: the specifications don’t state a Duty cycle or thermal limits. At 5.0 CFM at 90 PSI, we recommend allowing cooling breaks and monitoring temperature rather than assuming uninterrupted running.
What Routine Maintenance Does the Pump Require?
We keep the pump’s workshop engine healthy through routine checks: Check oil levels and maintain lubrication per the manual; Drain the tank after use to remove moisture, inspect fittings, and clean cooling surfaces for dependable airflow.
Which Pneumatic Tools Are Compatible With Its Airflow?
We can run pneumatic tools whose pneumatic tool requirements stay within 5.0 CFM at 90 PSI, or 6.0 CFM at 40 PSI. Airflow tool compatibility depends on each tool’s pressure and consumption specifications.
Is the Compressor Shipped Fully Assembled?
We can’t confirm whether it ships fully assembled; the available specifications don’t state packaging or setup requirements. Assembly requirements may include installing the included crankshaft, but check the seller or manufacturer for exact delivery details.
Conclusion
We find the NorthStar PK5020N a practical pick for tire inflation, intermittent tool use, and routine workshop tasks. Its cast-iron, two-cylinder pump, ball-bearing crankshaft, and copper-finned coolers support durable, serviceable operation. However, 5.0 CFM at 90 PSI and a 90 PSI maximum limit sustained, demanding applications. The 20-gallon horizontal tank saves floor space, but the 207-pound unit remains difficult to move. Choose it for compact capacity and dependable performance, not continuous high-demand work.
