MORE AIR, LESS WORRY
The Air-Zenith OB3 takes performance and durability to a new level. It builds on the success of the OB2 with stronger internal components, higher output, and better reliability. The OB3 delivers 4.5 CFM at 200 PSI with a 100% duty cycle, giving you constant, dependable airflow.
Its upgraded design includes a German-engineered wedge-locking bolt system. This prevents the internal piston and counterweight from loosening, a feature trusted in high-speed rail and subway systems. And with a 2.5-year manufacturer warranty, you can count on long-term reliability.
Installation is simple with pre-wired connections for power, ground, and trigger. The OB3 includes a 60A relay plugged into a harness that’s prewired into the compressor’s leads. This setup makes it easy to swap or replace the relay if needed. The oil-free design reduces maintenance while the weatherproof air filter and waterproof cooling fan provide extra protection in harsh conditions.
