Cole-Parmer Lightnin Heavy-Duty Gear Drive Mixer, air, 20-350rpm, 720in-oz, 3/4" x 60" shaft GO-50310-22

These variable-speed, gear-drive mixers are ideal for mixing your high-viscosity materials or large batches of water-like fluids. All models maintain speeds from 20 to 350 rpm (20:1 ratio) and generate enough torque to mix highly viscous fluids.
Gear-drive mixers mount with 20<deg> offset tank clamp (included). Available as either an air-powered or electric mixer.
Select from three speed options; 20 to 350 rpm (20:1 ratio), 20 to 280 rpm (14:1 ratio), or fixed speed of 350 or 280 rpm. The 3⁄4-hp mixers generate plenty of torque for your high-viscosity applications. |Air-powered mixers feature needle valve for precise speed control and built-in muffler for quiet operation. We recommend using an air filter/regulator and an air lubricator with all air-powered mixers—order from 'Accessories'.
Air-powered mixers operate with air input into the 3⁄8" (10 mm) NPT(F) inlet port on the needle valve. All air motors require 60 to 75 max psig of air pressure. One-quarter and 1⁄3-hp air motors require an air flow rate of 15 scfm. One-half and 3⁄4-hp air motors require an air flow rate of 30 scfm.|
