THREE-ONE MOTOR LABORATORY STIRRERS
How to Choose a Three-One Motor
Answer three questions → choose the capacity → choose the viscosity, and you will arrive at the best model. Click a series name to see its product page.
STEP 1Narrow down with three questions
Will you use it in a hazardous (explosion-proof) area?Agitating paints or organic solvents is hazardous-area work
Electric driveAir drive
Do you need to measure torque or viscosity change?Choose by whether recorded data is required
Accurate torque valuesTrends are enough
Will you use it in an ordinary laboratory?Choose Saf if a full guard over rotating parts is required
Safety cover requiredStandard type
STEP 2Choose by capacitySeries = motor power
BL Series40W
40Wup to approx. 5 L
BLh Series80W / Explosion-proof = Ex SeriesBest first choice!
80Wup to approx. 20 L
BLW Series120W / Explosion-proof = ExW Series
120Wup to approx. 50 L
*Capacities are guides for agitating water (low-viscosity liquid). Contact us for volumes over 50 L.
*The explosion-proof Ex Series is equivalent to BLh (80W), and the ExW Series to BLW (120W).
STEP 3Choose the model number by viscosityNumber = max. speed; smaller = higher torque
Each series has four types, and the number in the model name indicates the maximum rotation speed. Within the same series, types with a smaller number (lower maximum speed) have higher torque, while types with a larger number reach higher speeds but with lower torque.
Normally, use the 300 or 600 type for high-viscosity liquids, and the 1200 or 3000 type for low-viscosity liquids.
