ProBell
Easy to integrate, operate, and service, ProBell® brings convenience and high performance to any finishing application in any industry. The automatic rotary atomiser continually improves quality, transfer efficiency and cleanliness while spraying with robots, reciprocators or on a fixed mount.
Blended shaping air optimises rotary atomiser results
Unique to ProBell, blended shaping air optimises paint atomisation, pattern shape and transfer efficiency (coverage, wrap) for an excellent overall finish quality.
Inner shaping air and outer shaping air work together to drive paint to the part and adjust the spray pattern. This combination works especially well for finishing many different parts and complex shapes.
Applicators for top-quality automatic finishing
Graco’s ProBell Rotary Applicators deliver incredible finishing, transfer efficiency and precision spraying. Not only that: they’re lightweight and compact, making them perfect for lower payload robots or reciprocators. And with their flexible shaping air features, they’re an excellent choice for a vast array of applications and materials.
Superior finishing quality
ProBell Rotary Bell Atomisers bring convenience and performance to any finishing application. Their blended shaping air optimises paint atomisation and patterns and works with the automatic atomiser to guarantee quality and transfer efficiency.
Widely deployable
By blending the inner and outer shaping air, the ProBell obtains the exact pattern required to spray complex shapes. It’s compatible with solvent-borne and waterborne materials, in electrostatic and non-electrostatic applications.
Efficient spraying
Combining rotary bell atomisation with electrostatic technology means up to 95% transfer efficiency. The ProBell is precision-balanced for rotating up to 60,000 RPM, ensuring precision in complex applications, with lower waste and production costs.
Designed for automation
The ProBell is a lightweight, compact solution that can be mounted on lower payload robots or reciprocators. It can be integrated into an existing PLC set-up or combined with Graco monitors and you can expand your control options with ProBell controllers.
The Probell rotary bell atomiser explained
The ProBell Applicator range consists of high-performance paint applicators for automatic finishing. Thousands of customers have chosen this solution for its guaranteed top-notch finishing quality and its superb transfer efficiency. But what makes it so special?
- Versatile solution for automatic painting applications
The ProBell Rotary Applicator is designed for automatic painting applications. It can be mounted in a fixed position, on a reciprocating arm, or on a hollow or solid wrist robot.
- Next-generation rotary bell applicator technology
This rotary bell applicator atomises paint and coatings, achieving up to 95% transfer efficiency. The fluid is distributed by a cup which spins at 20,000 to 60,000 revolutions per minute (RPM). Because of the high rotation speed, the paint is subjected to high centrifugal force.
- High-quality finish thanks to unique blended shaping air features
ProBell’s blended shaping air technique combines inner and outer shaping air to optimise paint atomisation, pattern shape and transfer efficiency. This unique feature allows it to shape and propel the pattern toward the part, improving transfer efficiency and guaranteeing a high-quality finish.
- Electrostatic wraparound effect
To achieve maximum transfer efficiency, electrostatic effect is added. The electrostatic charge is created in the 100-kilovolt power supply within the rotary atomiser.
- Vast array of industrial applications
Thanks to its excellent transfer efficiency and the high-precision patterns obtained by its inner and outer shaping air, the ProBell is ideal for many industries, from automotive tier-1 and tier-2 suppliers (bumpers, rims, shock absorbers) to companies manufacturing tubes, cylinder-shaped objects, extruded aluminum parts, and glass.

Technology explained
A closer look at the probell’s special features
Spray anywhere thanks to its compact size
The ProBell’s compact size and small diameter allow for spraying in tight spaces. Its lightweight and compact design are also perfectly suited for lower payload robots or reciprocators.
Hollow wrist robot model:
o with electrostatic 6.1 kg (13.5 lb)
o without electrostatic 5.8 kg (12.7 lb)
Standard model:
o with electrostatic 4 kg (9 lb)
o without electrostatic 3.1 kg (6.9 lb)
High-quality results guaranteed with precision bell cups
o ProBell rotary bell cups precisely atomize many types of coatings into a variety of pattern sizes and flow rates.
o Pre-configured applicators include metal bell cups with serrated edges and standard plated surfaces.
o You can also opt for a metal bell cup without serrations or a smooth-edged composite construction bell cup.
o All metal bell cups have an aluminum core with a plated surface (standard or high wear for abrasive materials).
Spray complex shapes with blended shaping air
Unlike any other spray gun currently available on the market, the ProBell uses a combination of inner and outer shaping air to optimise atomisation, pattern shape and transfer efficiency, leading to a better overall finish quality.
Make your workspace safer with the 100 kv power supply
The ProBell power supply’s low-voltage cable connection improves safety while reducing system complexity.
Protect your equipment with the air cap cover
The ProBell Rotary Bell Applicator comes with a stainless steel air cap cover that protects the bell cup and the air cap.
