Viair 440c Compressor 200 PSI

The Viair 440c Compressor 200 PSI is a compact, high-output air compressor designed for automotive suspension systems, air tools, and pneumatic applications where reliable, consistent pressure delivery matters. Built by Air Lift—a trusted name in air suspension technology—this unit serves mechanics, fabricators, and enthusiasts who demand fast inflation cycles and the ability to maintain pressure under load. Whether you're setting up a new air suspension kit, running air tools in the shop, or maintaining tire pressure in remote conditions, the 440c delivers dependable performance in a footprint that fits tight engine bays and tool boxes.

This compressor uses a dual-piston design that cycles efficiently to build and hold 200 PSI maximum pressure with minimal heat generation and noise—critical for street-driven vehicles where cabin comfort matters. The sealed motor runs on 12-volt DC power, making it suitable for direct battery installation or integration into existing air systems via a relay and fused circuit. At 11.94 lbs and measuring 9.7 x 8.3 x 13.75 inches, the 440c is compact enough to mount under a vehicle or within a trunk-mounted air tank system without sacrificing duty cycle performance. Its thermal relief valve protects against overpressure, while the check valve prevents back-flow when the system is running—standard engineering that keeps your air suspension stable during cornering and load transfer.

The Viair 440c is ideal for owners running Air Lift suspension kits, Accuair systems, or any aftermarket air spring platform that requires on-demand leveling and ride height adjustment. It pairs seamlessly with 1/4-inch airline tubing and standard quick-disconnect fittings, making installation straightforward for DIY fabricators and professional shops alike. Mechanics appreciate this unit's reputation for longevity when wired with a quality compressor relay and protection circuit—proper electrical integration ensures years of reliable service. For vehicles ranging from lowered street cars and trucks to lifted off-road platforms, the 440c strikes the balance between compact size, adequate output, and proven reliability that experienced builders trust.
