It operates on the venturi principle: compressed air supplied to the cast aluminum inlet head generates a high-velocity jet through an internal nozzle, inducing a substantially amplified airflow through the galvanized steel horn; the ASI-4100 is the largest model in the ASI line (above the ASI-1000, ASI-1500, and ASI-2500), delivering the highest CFM output of the series at rated inlet air pressure. The unit features a large-diameter galvanized steel flared horn for maximum airflow induction, a cast aluminum venturi body with an \"AIR\" inlet port label, and a bayonet-style horn-to-body coupling with a locking bail handle visible on the horn; as a new — other unit (original manufacturer packaging with shipping box wear), it is ready for immediate deployment in construction, industrial maintenance, oil and gas, marine, and confined-space entry applications per OSHA 29 CFR 1910.146 ventilation requirements.\u003c\/p\u003e\n\u003ch3
