Allegro 9518-06 Medium 2100 CFM 1in NPT Pneumatic Venturi Blower

The Allegro Industries 9518-06 is a new medium-size pneumatic venturi blower designed for confined space ventilation, delivering 2,100 CFM total air flow at 40 psig supply pressure via a 1 in NPT air inlet. The venturi design uses compressed air to entrain ambient air through the large-diameter conical horn — no electric motor, no rotating parts, and no spark hazard — making it suitable for use in flammable or explosive atmospheres where electrically powered blowers are prohibited. The aluminum construction keeps weight low while providing corrosion resistance; a carry handle is integrated into the horn body for easy repositioning, and the unit includes a grounding wire with alligator clips to dissipate static charge during operation in hazardous locations. Compatible with standard compressed air lines at 40–100 psig; higher supply pressure increases both air flow and entrainment ratio. Meets OSHA confined space entry ventilation requirements (29 CFR 1910.146) when used with appropriate ducting.
