We find the VIAIR 480C dual compressor well suited to air suspension, tanks, horns, and other demanding pneumatic systems. It delivers up to 200 PSI, 3.53 CFM, and fills a 2.5-gallon tank from empty to 200 PSI in about 2 minutes, 22 seconds. Its 46-amp draw requires properly sized wiring and a capable 12-volt supply. Thermal protection, relays, and a pressure switch aid operation, while 75 dB noise and installation complexity warrant consideration. We’ll examine the test and trade-offs below.
Key Takeaways
- The dual VIAIR 480C setup delivers up to 3.53 CFM and 200 PSI for demanding pneumatic systems.
- It fills a 2.5-gallon tank from empty to 200 PSI in about 2 minutes, 22 seconds, with a ±10-second tolerance.
- Duty cycle is 100% at 100 PSI but drops to 50% at 200 PSI, limiting sustained high-pressure use.
- Its 46-amp maximum draw requires properly sized wiring and a reliable 12-volt power source.
- Thermal protection, relays, a pressure switch, filters, and mounting hardware are included, but installation takes planning and it operates at 75 dB.
2.5-Gallon Tank Fill Test
To evaluate its tank-filling performance, we timed the VIAIR 480C Dual filling a 2.5-gallon tank from empty to 200 PSI. The test took 2 minutes, 22 seconds, with a stated tolerance of ±10 seconds.
This result gives you a practical benchmark for Tank recovery after the tank has been depleted, though actual times may vary with voltage, temperature, and system setup. The compressor’s 3.53 CFM airflow supports this measured fill rate, while its 50% duty cycle at 200 PSI limits continuous operation at that pressure.
For fill consistency, repeat the test under comparable conditions and track elapsed time across runs.
Detailed features
Beyond its measured fill rate, the VIAIR 480C Dual combines thermal overload protection with components for a two-compressor installation. Thermal protection helps limit overheating during demanding operation, while two heavy-duty 40-amp relays manage power to the 12-volt compressors.
We also get a pressure switch set to turn on at 165 PSI and shut off at 200 PSI, plus a fuse holder and mounting hardware. Remote filtration places the filter assemblies away from the compressor intakes, allowing flexible installation and easier access.
Each pewter compressor supports up to 200 PSI; together, the system draws a maximum 46 amps and delivers 3.53 CFM.
Pros and Cons
We’ll weigh the VIAIR 480C Dual’s 3.53 CFM airflow, 200 PSI maximum pressure, and included installation components against its 46 A current draw and 75 dB noise level.
We’ll also consider its duty-cycle limits: 100% at 100 PSI and 50% at 200 PSI. This comparison will help you assess its strengths and trade-offs for your air-system needs.
Pros
The VIAIR 480C Dual’s main advantage is its capacity to support demanding pneumatic systems: each 12V compressor delivers up to 3.53 CFM and 200 PSI, with a 100% duty cycle at 100 PSI. Together, the units can fill a 2.5-gallon tank from empty to 200 PSI in about 2 minutes, 22 seconds.
We also value the built-in Thermal protection, which helps limit overheating during demanding operation. The included dual relays support the electrical load, while the pressure switch automates operation between 165 PSI cut-on and 200 PSI cut-off. This combination suits air suspension, horns, tanks, and off-road pneumatic systems.
Cons
Although the dual setup delivers strong output, it draws up to 46 A and requires suitable wiring, relays, and a reliable 12V power source. This High current draw may exceed the capacity of existing circuits, so we should verify electrical limits before installation.
The included 40A relays and fuse holder help, but they don’t eliminate the need for correctly sized cables and secure connections. Installation complexity also increases when we mount two compressors, route intake filters, and integrate the pressure switch with a tank.
At 75 dB, the system may sound loud in confined spaces. Its 50% duty cycle at 200 PSI limits sustained high-pressure operation.
Concluding thoughts
For systems that need strong, sustained airflow, the VIAIR 480C Dual offers two 12V compressors rated at 3.53 CFM and up to 200 PSI, with a 100% duty cycle at 100 PSI. We’d consider its dual-compressor design for air suspension, tanks, horns, and off-road pneumatic systems requiring dependable capacity.
Thermal overload protection supports operation under demanding conditions, while included relays, pressure switch, filters, and mounting hardware simplify setup. Check that your electrical system can supply up to 46 amps and that 75 dB noise suits your location.
For Long term reliability, follow installation requirements; installation flexibility depends on available space and mounting options.
Frequently Asked Questions
What Vehicles or Systems Are Compatible With the VIAIR 480C Dual Compressor?
We can use the VIAIR 480C Dual Compressor with 12V vehicles running Air suspension systems, onboard air systems, air tanks, air bags, air horns, and off-road or industrial pneumatic equipment, provided electrical capacity supports its 46-amp draw.
What Does the One-Year Manufacturer Warranty Cover?
Warranty coverage is a safety net against workmanship defects for one year. We can’t confirm exclusions or the claim process from the provided details, so contact VIAIR with proof of purchase to verify eligibility and next steps.
Can the Compressors Be Mounted Remotely?
Yes, we can use Remote Mounting for these compressors: the pack includes remote-mount filter assemblies, supporting Installation Flexibility. We should still follow VIAIR’s installation instructions and allow adequate airflow, secure mounting, and accessible maintenance.
What Components Are Included in the Value Pack?
You’ll find two 480C compressors in the value pack, each rated for up to 200 PSI. Included Components and Pack Contents also comprise two 40A relays, a pressure switch, fuse holder, remote-mount filters, and mounting hardware.
What Are the Compressor’s Model Number and UPC?
The compressor’s Model number is 48012, and its UPC is 651760722871. For a UPC lookup, we can use that 12-digit code to identify the VIAIR 480C Dual Air Compressor Value Pack accurately.
Conclusion
The VIAIR 480C Dual pack is a strong choice when your vehicle needs dependable, high-volume air.
