Spot cooling vortex tube Model 3825

for cold air

Overview
EXAIR's Adjustable Spot Cooler System (one cold outlet) includes everything needed for a single-point cooling station that provides a cost-effective, reliable, maintenance-free solution for a range of industrial spot-cooling needs. A knob allows precise temperature selection from -30°F (-34°C) to room temperature. A swivel magnetic base enables easy mounting and portability. A Single Point Hose Kit (with cone and fan nozzle) directs the cold air. 15 and 30 SCFM (425 and 850 SLPM) generators are supplied and a 25 SCFM (708 SLPM) generator is installed. An Automatic Drain Filter Separator is included to ensure a supply of clean air. No moving parts or CFCs ensure maintenance-free operation.
