Cosmostar 55 Gallon Paint Mixer With Expandable Blades

The Cosmostar 55 Gallon Paint Mixer features an expandable blade-type design crafted from stainless steel for strong corrosion resistance and long life. It is suitable for paints, epoxy, resins, and silicones. The tool is simple to use: insert the blade into a drill or agitator, tighten, and begin mixing. Ensure the blade is fully submerged to minimize splatter. Cleaning is straightforward, with latex paint rinsed in water and oil-based paints cleaned with thinner.
Cosmostar Stainless Steel Mixing Expandable Blade 55 Gallon

This stainless steel mixer uses an expandable blade design to speed up mixing and deliver consistency across materials like paint, ink, and chemicals. It’s corrosion-resistant and easy to clean—submerge the blade in water while spinning for latex paints, or use paint thinner for oil-based applications. The setup is drill-ready and designed to outperform manual stirring for deep pours and viscous liquids.
COSMOSTAR 55 Gallon Pneumatic Agitator

This 1/8 HP bung-mounted pneumatic agitator uses a heavy-duty 200 L stainless steel shaft and a 6″ SUS expandable propeller. The AM0705 air motor provides up to 1.3 N·m torque and up to 2500 RPM, making it suitable for paint, ink, chemicals, and food applications. It is designed for harsh environments, with an air motor that offers longevity and easy maintenance, even under high-temperature conditions up to 120 C.
Cosmostar Stainless Steel Mixing Expandable Blade 55G

Designed to maximize mixing efficiency, this expandable blade mixer uses stainless steel for corrosion resistance and can handle paints, inks, chemicals, food, and more. In operation, insert the blade into a drill or agitator, tighten, and begin mixing. Submerge the blade to avoid splatter, and rely on the tool to produce a smooth, uniform mix for deep pours and viscous liquids. Cleaning mirrors the other Cosmostar blades—rinse latex paints or use paint thinner for oil-based materials.
COSMOSTAR 55 Gallon Pneumatic Agitator Clamp Mount

This clamp-mount drum mixer brings a robust 55-gallon mixing solution with an AM0705 three-piston air motor, a 200 L stainless steel shaft, and dual 3.9″ SUS gear propellers for versatile material compatibility. The clamp design enables quick installation on the side of a 55-gallon open drum. With a torque capacity up to 8.9 in-lbs and a maximum speed of 2500 RPM, it supports diverse industries and applications while emphasizing long-term reliability.
COSMOSTAR M0707 1/2 HP Bung Mount 55G Pneumatic Agitator

Ideal for painting, printing, chemicals, food, and baking applications, the M0707 bung-mount pneumatic agitator offers straightforward installation and durable operation. Its air motor is designed for longevity with minimal maintenance, and its accessories are built to extend service life in challenging environments. The design supports a wide range of materials and viscosities, making it suitable for heavy-duty job-site mixing.
BayTec Drum Mixer Blade for Tight Head 55 Gallon

The BayTec mixer blade is designed for tight-head drums with three aluminum mixing heads and a 36″ shaft. The 2 1/8″ head diameter and half-inch shaft provide a firm grip and solid mixing for mid-viscosity materials. This setup enables efficient manual or power-assisted mixing, especially when quick access and reliability are required on job sites or workshops.
BayTec Swing T-Style Mixer Blade for 55 Gallon

The BayTec Swing T-Style Mixer Blade features a single T-style cast aluminum mixing head that fits standard 1/2″ chucks on power drills. It is ideal for heavy liquids, dry materials, coatings, resins, and inks, offering a rugged, portable mixing solution for on-site use and small batch production where speed and maneuverability are key.
Buying Guide
- Drum compatibility: Confirm bung type (open vs tight head) and drum dimensions before selecting a mixer or blade length to ensure a proper fit and safe operation.
- Motor or pneumatic power: Pneumatic agitators provide strong torque and resistance to sparks in certain environments, while electric drill-compatible blades offer flexibility for smaller jobs and easier storage.
- Blade design: Expandable blades improve mixing speed and uniformity for viscous materials, but ensure corrosion resistance matches the intended liquids (paint, epoxy, resins, inks, etc.).
- Material compatibility: Stainless steel blades resist rust, but verify chemical compatibility with additives and solvents used in your mixes.
- Ease of cleaning: Consider blades that are easy to rinse or submerge, especially when switching between materials to prevent cross-contamination.
- Installation and maintenance: Clamp or bung-mount systems vary in setup time and tool requirements. Look for durable hardware and replaceable parts like propellers and shafts for longer service life.
- Safety and handling: Ensure proper containment to manage splatter, especially with high-viscosity liquids and deep pours. Follow manufacturer guidelines for operation speeds and torque limits.
- Application fit: For painting, coatings, and inks, prioritize blades designed for thick liquids; for resins and epoxy, choose blades with robust build and submersion-friendly geometry.
