Air Lift Viair 444C Dual Pack Air Compressor – 200 PSI | 100% Duty Cycle

Power your air suspension system with the confidence of dual-compressor redundancy — the Air Lift Viair 444C Dual Pack delivers two 444C chrome compressors with Viair’s newly developed patents-pending intercooler head assembly, a 100% duty cycle at 100 PSI, and a 200 PSI maximum working pressure. Designed for demanding air suspension applications where reliability, fill speed, and continuous operation are non-negotiable, the 444C Dual Pack includes stainless steel braided leader hoses with inline check valves to protect the compressors from high-amperage restarts — a complete, professional-grade dual compressor solution for air ride builds.

Key Features:

• Dual 444C chrome compressors — two compressors for faster fill times, redundancy, and the ability to run independent circuits
• Patents-pending intercooler head assembly — newly developed head design that reduces operating temperatures for improved reliability and longevity under continuous use
• 100% duty cycle at 100 PSI — capable of continuous operation at 100 PSI without overheating or mandatory rest periods
• 200 PSI maximum working pressure — sufficient for the most demanding air suspension and air management systems
• Stainless steel braided leader hoses with inline check valves — protects each compressor by eliminating the possibility of high-amperage restarts from back-pressure
• 12-volt permanent magnetic motor — direct 12V connection for straightforward integration with vehicle electrical systems
• Complete hardware kit — remote mount brackets, fittings, air filter assemblies, spare filter elements, and all mounting hardware included

Performance Benefits:

• Dual Compressor Speed: Two 444C compressors working simultaneously fill air bags significantly faster than a single compressor — critical for air suspension systems that require rapid height adjustment
• Redundancy: Dual compressor configuration means the system continues to function if one compressor requires service — a significant reliability advantage for daily-driven air suspension builds
• Intercooler Head Technology: Viair’s patents-pending intercooler head reduces compressor operating temperatures, extending service life and maintaining performance under sustained high-demand use
• Check Valve Protection: Inline check valves in the stainless braided leader hoses prevent back-pressure from reaching the compressor when it cycles off, eliminating the high-amperage restart condition that causes premature compressor failure
• 100% Duty Cycle Capability: Unlike lower-rated compressors that require rest periods, the 444C is rated for 100% duty cycle at 100 PSI — suitable for continuous operation in demanding air management applications
• 200 PSI Maximum: High maximum working pressure provides headroom for aggressive air management systems and ensures the compressors are never operating near their limits

What’s Included:

• (2) Viair 444C chrome compressors with patents-pending intercooler head
• (2) Air filter assemblies
• (2) Remote mount brackets
• (2) Sets of remote mount fittings
• (2) Sets of spare air filter elements
• (8) Sets of nuts, bolts, washers, and lock washers
• (2) Stainless steel braided leader hoses with inline check valve

• Does not include: relays, pressure switch, or air line for remote air filter relocation

Installation Notes:

• Professional installation strongly recommended for air suspension compressor systems
• Relays, pressure switch, and air line for remote air filter relocation are not included — source separately based on your air management system requirements
• Each compressor draws up to 38 amps — ensure your vehicle’s electrical system and wiring are rated for the combined load of both compressors running simultaneously (up to 76 amps total)
• Use appropriately rated fusing and wiring for each compressor circuit
• Mount compressors in a location with adequate airflow for cooling — avoid enclosed spaces that trap heat
• Ensure inline check valves are installed correctly to protect compressors from back-pressure

Viair 444C Intercooler Head Technology:

Viair’s patents-pending intercooler head is a significant advancement in compressor head design for air suspension applications. Traditional compressor heads accumulate heat during sustained operation, which degrades performance and accelerates wear on internal components. The intercooler head design dissipates heat more effectively, allowing the 444C to maintain consistent output and reliability under the continuous, high-demand operation that air suspension systems require. Combined with the inline check valve protection on the stainless braided leader hoses, the 444C Dual Pack is engineered to deliver long-term reliability in the most demanding air ride applications.

Why Dual Compressors?

A single compressor air suspension system is functional, but a dual compressor setup delivers meaningful advantages for serious air ride builds. Two compressors working simultaneously fill air bags faster — reducing the time required to raise the vehicle from slammed to ride height. Dual compressors also provide redundancy: if one compressor requires service, the system continues to operate on the remaining unit. For daily-driven air suspension builds where reliability and fill speed are priorities, the 444C Dual Pack is the professional solution.

Why Air Lift / Viair?

Air Lift has been engineering air suspension systems since 1949, and Viair is one of the most trusted names in high-performance air compressors for automotive applications. The combination of Air Lift’s air suspension expertise and Viair’s compressor engineering delivers a dual compressor solution that is trusted by professional air ride builders and enthusiasts worldwide.

Perfect For:

• Air suspension builds requiring fast fill times and dual compressor redundancy
• Daily-driven air ride vehicles where reliability and continuous operation capability are critical
• High-demand air management systems running multiple air bags or large air tank volumes
• Show and performance builds where rapid height adjustment is required
• Anyone upgrading from a single compressor setup to a professional dual compressor configuration

Pro Tip: Wire each compressor to its own dedicated relay and fuse circuit rather than running both from a single relay. Independent circuits provide better electrical protection and allow each compressor to draw its full 38 amps without overloading a shared circuit.

Note: Relays, pressure switch, and remote air filter relocation air line are not included. Plan your air management system wiring and components before installation to ensure all required parts are on hand.
