Direct-Drive Drum Lid Mixer, Air Motor,4 hp,6" prop

55 Gallon Drum Mixer with Air Motor � 4 HP Variable Speed Industrial Agitator

If you mix liquids in drums, you know the mess can cost you time and money.

This 55 gallon drum mixer with air motor helps reduce vapor loss and stops splashing. It gives you steady, controlled mixing inside a sealed drum cover. That means cleaner work, safer handling, and less wasted product.

This unit mounts directly to a standard 55 gallon open-head steel drum. It also fits bulk tanks that use a 55 gallon drum opening. You don�t need special adapters for common drum setups. Just position it, secure the cover, and you�re ready to mix.

The mixer is built for medium viscosity liquids. It works well for oils, coatings, chemicals, cleaners, and similar products that need steady agitation. If your liquid is thicker than water but still flows easily, this mixer is designed for that range.

The motor is a powerful 4 HP air motor. It runs at variable speeds from 300 to 3,000 RPM. You control the speed using the included valve. This gives you more control over blending, suspension, and circulation. You can start slow to prevent splashing, then increase speed as needed.

The motor includes a muffler to reduce noise. For full power output, the 4 HP motor requires 130 CFM at 100 PSI. Make sure your air supply can support this demand before ordering.

The shaft and propellers are made from 316 stainless steel. This material resists corrosion and handles harsh chemicals better than standard steel. The unit includes two 6-inch propellers for stronger circulation and better top-to-bottom mixing.

The drum cover is carbon steel and unlined. If you need a stainless steel cover, that option is available by special order.

Because the motor is air-powered, this mixer is a strong choice for hazardous or flammable environments. There are no electrical sparks to worry about. That adds a layer of safety in chemical plants, paint shops, and industrial facilities.

At 50 pounds, this unit is solid and durable. It is built for long-term use in demanding settings. Once mounted, it stays stable during operation.

If you need a dependable industrial drum agitator for 55 gallon drums, this air-powered mixer delivers power, control, and durability in one system.

Additional Description

In real work settings, control matters.

If you�re blending chemicals, suspending solids, or keeping materials from settling, you need consistent movement inside the drum. This mixer keeps liquids circulating evenly so you don�t end up with thick material at the bottom and thin liquid at the top.

The adjustable speed is useful when working with different products. You can mix gently to avoid foam. Or increase speed when you need stronger agitation.

Air-powered systems are often preferred in plants where flammable vapors may be present. With no electric motor, you reduce ignition risks.

This unit is a good fit for manufacturing, maintenance shops, chemical processing, water treatment, and industrial supply operations. If you already use compressed air in your facility, installation is simple.
