About Air Venturi
Air Venturi is the biggest name in US airgun air supply, covering the whole ladder from the G9 hand pump through the portable Nomad and RovAir lines up to the tank-capable Krypton and the Hill-built EVO-310. The Nomad set the template for the field-portable compressor category, running from a wall outlet or car battery with adjustable auto shut-off, and the current Nomad III cuts fill times roughly a quarter versus its predecessor while dropping the oil-between-fills maintenance. US-based parts and service is a genuine differentiator over direct-import alternatives.
