Quiet Air Source With Variable Output, 1 Each

The Quiet Air Source With Variable Output by United Scientific is a 250 W blower that supplies clean air to air tracks, air tables, and other pneumatic equipment. It delivers 35 m³/hour at 0.70 kPa overpressure while operating at under 58 dB, so it can run in an occupied classroom without drowning out instruction. Physics teachers and teaching-lab coordinators use it to float gliders and pucks for friction-reduced motion and collision experiments.
