We find the VIAIR 480C Dual Compressor Pack a capable 12-volt onboard-air system for air suspension, tanks, and other pneumatic equipment. Its two compressors deliver 3.53 CFM and up to 200 PSI, with continuous operation supported at 100 PSI but a 50% duty cycle at 200 PSI. Expect a 40-amp maximum draw, 75 dB noise, and a 22.1-pound assembly. Included relays, pressure switch, and remote filters simplify integration; we’ll cover fit, installation, and trade-offs below.
Key Takeaways
- The VIAIR 480C Dual pairs two 12-volt compressors, delivering up to 3.53 CFM and 200 PSI for onboard air systems.
- It runs continuously at 100 PSI, but its duty cycle drops to 50% at 200 PSI.
- It fills a 2.5-gallon tank from empty to 200 PSI in about 2 minutes, 22 seconds.
- Installation requires capacity for up to 40 amps, secure mounting, and space for the 22.1-pound assembly.
- Included relays, pressure switch, fuse holder, and remote filters aid setup; expect 75 dB noise and a one-year limited warranty.
Dual 480C Compressor Pack
The VIAIR 480C Dual Compressor Pack pairs two 12-volt chrome compressors for air suspension, tanks, air bags, horns, and other pneumatic equipment. Its dual-compressor layout supports systems that need a dedicated onboard air supply, including off-road and industrial setups.
We can assess system compatibility by checking the vehicle’s 12-volt electrical capacity, available mounting space, and pneumatic connections before installation. The included relays, pressure switch, fuse holder, remote-mount filters, and hardware provide key components for setup.
These parts allow several installation options, depending on equipment placement and wiring access. Confirm your tank and hose arrangement suits the intended application before connecting the pack.
Detailed features
With a 12-volt supply, the VIAIR 480C Dual delivers up to 200 PSI and 3.53 CFM, with a 100% duty cycle at 100 PSI and 50% at 200 PSI. We can use its dual compressors to fill a 2.5-gallon tank from empty to 200 PSI in about 2 minutes, 22 seconds.
The system draws up to 40 amps and operates at 75 dB. Thermal protection helps guard the motors against overheating. Remote filtration uses included remote-mount filter assemblies, while a 165 PSI cut-on and 200 PSI cut-off switch controls tank pressure. The kit also includes two 40-amp relays, a fuse holder, and mounting hardware.
Pros and Cons
We’ll assess the 480C Dual’s advantages, including its 3.53 CFM airflow, 200 PSI capacity, and included relays and pressure switch.
We’ll also consider trade-offs such as its 40-amp current draw, 75 dB noise level, and 22.1-pound weight. This comparison will help you determine whether its performance suits your installation and air-system demands.
Pros
For air systems that demand sustained output, the VIAIR 480C dual pack offers two 12V compressors, a 3.53 CFM airflow rating, and a 200 PSI maximum pressure. We can use its 100% duty cycle at 100 PSI to support extended operation, while the 50% rating at 200 PSI suits higher-pressure demands.
VIAIR reports filling a 2.5-gallon tank from empty to 200 PSI in 2 minutes, 22 seconds, supporting fast inflation. The included 40-amp relays, pressure switch, and remote-mount filters simplify system integration. Thermal overload protection and dual motors contribute to reliable performance in air suspension, tank, and off-road applications.
Cons
Despite its strong output, the VIAIR 480C dual pack has trade-offs: it draws up to 40 amps, produces 75 dB of noise, and weighs 22.1 pounds, so we’ll need adequate electrical capacity, a suitable mounting location, and tolerance for compressor noise. This High Current demand may require careful wiring and a capable 12V supply, particularly during sustained operation.
At 100 PSI, the compressors can run continuously, but duty cycle drops to 50% at 200 PSI, limiting high-pressure runtime. The 22.1-pound assembly also complicates installation in space-constrained vehicles. We get only a one-year Limited Warranty against workmanship defects, which offers modest coverage for a demanding component.
Concluding thoughts
Overall, the VIAIR 480C dual pack suits installations that need a 12V air supply rated up to 200 PSI, with 3.53 CFM airflow and a 100% duty cycle at 100 PSI. We’d consider its 40-amp maximum draw, 75 dB noise level, and 50% duty cycle at 200 PSI when sizing wiring, controls, and tank capacity.
The included relays, pressure switch, fuse holder, remote filters, and mounting hardware simplify setup, but installation considerations include secure mounting and adequate electrical protection. For long term reliability, we’d follow the duty-cycle limits and use the one-year workmanship warranty as a baseline, not a substitute for routine inspection.
Frequently Asked Questions
What Vehicles Are Compatible With the VIAIR 480C Dual Air Compressor?
We can use the 12V VIAIR 480C dual compressor in trucks and SUVs equipped with compatible electrical systems and suitable mounting space. Truck compatibility and SUV compatibility depend on installation, wiring capacity, and intended pneumatic equipment.
Can the Compressors Inflate Tires Directly Without an Air Tank?
Yes—we can use Direct Tire Inflation without an air tank, though Tankless Airflow depends on proper hose and fitting connections. As the compressors hum, connect them directly to a tire; their 3.53 CFM output supplies inflation air.
How Should the Remote Air Filters Be Positioned?
For Remote Filter Placement, we recommend mounting each remote filter assembly in a clean, dry, cool location, away from exhaust heat, water, dust, and road spray. During Filter Mounting, we’ll keep inlet hoses unkinked and unobstructed.
What Maintenance Do the Compressors Require?
To keep these compressors running smoothly, we recommend routine cleaning of remote filters and cooling surfaces, plus electrical inspections of wiring, relays, and fuses. We should also check mounting hardware and hoses regularly for looseness or damage.
Is Professional Installation Recommended for This Compressor System?
Professional Installation isn’t mandatory, but we recommend it if you’re unfamiliar with high-current 12V systems. We must prioritize Wiring Safety: each compressor draws up to 40 amps, so use properly rated wiring, relays, fuses, and secure connections.
Conclusion
We find the VIAIR 480C dual pack a capable choice for air suspension, horns, and other onboard pneumatic needs. Its 3.53 CFM output, 200 PSI rating, and 100% duty cycle at 100 PSI support sustained use, while the included relays, pressure switch, filters, and hardware simplify setup. Buyers should plan for its 12-volt electrical demands, installation space, and compressor noise. Need dependable air on the trail or road? This kit offers substantial capacity, backed by a one-year workmanship warranty.
