An air mixer uses compressed air to agitate paint, coatings, and solvents without electrical sparks. This makes it the safest mixing solution for flammable materials while offering adjustable speed, portability, and low maintenance.
Introduction
Paint and coating manufacturers face strict safety requirements when mixing flammable solvents, pigments, and resins. Electric mixers pose spark risks in volatile environments. An air mixer eliminates this hazard while delivering consistent, controllable agitation. This article explains why air mixers are the preferred choice for paint and coating applications.
Safety Benefits
- No Electrical Sparks: Compressed air power eliminates ignition sources.
- Inherent Explosion Protection: No need for costly explosion-proof electrical certifications.
- Safe in Open Vessels: Operators can work safely near open drums and tanks.
Performance Benefits
- Adjustable Speed: Change RPM instantly by adjusting air pressure.
- Uniform Mixing: Consistent agitation prevents pigment settling and ensures color uniformity.
- Portable Design: Lightweight units move easily between drums and workstations.
- Low Heat Generation: Air motors run cooler than electric motors, reducing solvent evaporation.
Selection Tips for Paint Mixing
- Choose stainless steel wetted parts for solvent compatibility.
- Select propeller-style impellers for low-viscosity paints.
- Use clamp or drum-lid mounts for batch flexibility.
- Ensure air supply pressure matches the motor rating.

FAQ
Q1: Is an air mixer safe for solvent-based paints?
Yes. Air mixers are inherently explosion-proof and safe for flammable solvents.
Q2: How do I prevent paint from splashing during mixing?
Start at low air pressure and gradually increase speed. Use baffles or slower RPM for open containers.
Q3: What impeller type works best for paint?
Propeller impellers work well for low to medium viscosity paints. Anchor or paddle impellers suit thicker coatings.
Q4: Can one air mixer handle multiple drum sizes?
Yes. Portable clamp-mounted mixers with adjustable shafts accommodate various drum heights.
Q5: Does Kunshan DSV offer ATEX-certified mixers?
We build mixers to industrial safety standards. Contact us for specific certification requirements.
