Supply Pressure Typically up to 120 psig (8.3 bar).
Thrust Output Very High. Exact thrust (in lbs or kN) depends on supply pressure and piston size, but this model is designed for demanding applications.
Spring (if applicable) Spring Range For spring-return models, the "109" defines a specific spring that determines the fail-safe action and the air pressure required to compress it.
