Cold air nozzle Model 5215

coolingfor micro-lubrication applicationsindustrial

Overview
The Cold Gun Aircoolant System™ (single cold outlet) delivers a continuous stream of clean, cold air approximately 54°F (30°C) below supply air temperature using vortex cooling. Available in standard and High Power versions. The system is quiet, has no moving parts, and is portable with a magnetic base. It removes heat where liquid coolant is impractical, extending tool life and improving productivity while avoiding costs and safety issues associated with liquid coolants and mist systems.

Applications

• Tool sharpening
• Drill and cutter grinding
• Routing
• Plunge and form grinding
• Milling
• Surface grinding
• Drilling
• Tire grinding
• Band sawing
• Plastic machining
• Laser cutting
• Chill rolls
• Setting hot melt adhesives

Advantages

• Prevents smearing of metals or plastics
• Produces a dry finished part
• Eliminates wheel loading
• Low operating cost
• Compact, lightweight and portable
• No moving parts — maintenance free
• Quiet operation
• No coolant purchase or disposal cost

Accessories (included / recommended)

• Single Point Hose Kit (included with Model 5215 and Model 5230) — for concentrated airflow in drilling and grinding.
• Dual Point Hose Kit (included with Model 5315 and Model 5330) — for heat over larger areas such as band sawing, milling and chill rolls.
• Nozzles: 3/8" (10 mm) Cone Nozzle and 1-1/4" (32 mm) Fan Nozzle (included with single-outlet systems).
• Filter separator: manual drain (standard systems) or automatic drain (High Power Model 5230 uses automatic drain).

5330 High Power Cold Gun | 100 | 6.9 | 30 | 850 | 82

How it works (summary)
The Cold Gun uses a vortex tube to split compressed supply air into hot and cold low-pressure streams. Secondary air is drawn in; the hot stream exhausts through a hot air outlet and the cold stream is delivered through the flexible hose to the point of use. Magnetic base allows quick mounting and repositioning.

Other considerations

• Designed for full line pressure of 80–100 PSIG (5.5–6.9 BAR); reduced temperature drop and flow at lower pressures.
• Clean, filtered compressed air is essential; a filter separator that removes moisture, dirt and particulates is included. Optional oil removal filter available.
• Cycling or solenoid control can save compressed air; a manual shutoff valve is recommended for on/off control.
