For more than a century, Schaefer Brush has built brushes that power industries forward. While our catalog offers hundreds of proven designs, many projects demand something entirely unique. That’s where our custom brush capabilities deliver exceptional value.

Our work in the OEM sector, particularly in the HVAC industry, showcases our ability to design brushes that integrate seamlessly into specialized equipment. Whether the need is a unique diameter for tube cleaning or a brush that’s completely non-sparking, we engineer solutions that others can’t match.

Solving Unique Industry Challenges

Every custom project starts with a problem that can’t be solved off the shelf. Schaefer Brush has partnered with customers to:

• Design brushes for automated processes that require exact fit and performance.
• Replace obsolete brushes so customers can maintain legacy equipment without costly redesigns.
• Experiment with different filament types to identify the optimal material for cleaning or finishing specific surfaces.
• Improve cleaning efficiency with tailored materials and measurements for targeted results.

Material Expertise You Can Count On

Our supply network is as diverse as the industries we serve. Schaefer Brush can source and work with materials ranging from inconel and food-grade nylons to special animal fibers and high-performance alloys.

We frequently manufacture with:

• High-temperature filaments for extreme environments.
• Non-sparking materials for hazardous conditions.
• Corrosion-resistant metals for long-term durability.

With over a century of experience, our team guides customers toward the best materials for their application, ensuring reliability, performance, and safety.

A Clear Process from Concept to Delivery

Our custom brush process is designed for precision:

1. Concept & Drawings – For new customers, we require technical drawings to ensure accuracy. Existing customers may access our in-house engineering for design assistance.
2. Specification Refinement – Collaborating to confirm material choice, filament density, and brush geometry.
3. Prototype (as needed) – Offered for large-scale or critical applications.
4. Manufacturing – All work is completed in our Wisconsin facility, ensuring quality control.
5. Delivery – Typical lead time is 4–6 weeks for design, with final delivery in up to 12 weeks depending on material availability.

Schaefer Brush — Custom-Made to Fit Your Challenge.

Spin Grit and Spin Clean brushes are designed to deliver superior cleaning performance, especially in industrial applications like condenser cleaning. These brushes are built with specialized features, making them an ideal choice for achieving better results compared to traditional cleaning tools.

What Are Spin Grit and Spin Clean Brushes?

These brushes are crafted with a single stem construction and silicon carbide and nylon coextruded bristles. The silicon carbide throughout the filaments provide exceptional durability and abrasive power, which are ideal for cleaning tasks that require more than just a regular scrub. The bristles in these brushes are uniquely designed to be oversized. This allows the long bristles to bend over during use, ensuring that the aggressive filaments come into maximum contact with the surface to be cleaned.

In addition to the long bristles, our Spin-Clean brushes feature short bristles strategically positioned to reach into the grooves, ensuring thorough cleaning of every part of the surface, including difficult-to-reach areas.

Applications and Benefits

Spin Grit and Spin Clean brushes are ideal for cleaning and maintaining condenser tubes. Specifically, the design of these brushes makes them perfect for brass tubes. Their unique bristle structure allows for superior contact with the lands and grooves of the tube, resulting in better cleaning performance.

Some of the benefits of these brushes include:

• Increased Surface Contact: The oversized bristles allow the filaments to lay over and make more aggressive contact with the surface, providing enhanced cleaning capabilities.
• Longer Lifespan: The durable coextruded silicon carbide and nylon bristles offer longer life than conventional brushes, reducing the need for frequent replacements.
• Efficient Cleaning: The long bristles contact the surface aggressively, while the short bristles reach into the grooves for a complete clean.

These features combine to provide a cleaner surface with fewer passes, reducing cleaning time and improving overall efficiency.

Why Choose Spin Grit and Spin Clean Brushes?

Compared to conventional brushes, Spin Grit and Spin Clean brushes offer several distinct advantages:

• Aggressive Cleaning: The bending bristles and coextruded silicon carbide and nylon filaments work together to remove stubborn contaminants.
• Durability: These brushes last longer than traditional cleaning brushes, reducing maintenance costs.
• Precision Cleaning: With the combination of long and short bristles, these brushes can clean both flat surfaces and deep grooves, providing thorough cleaning without damage to the surface.

For businesses seeking to improve cleaning efficiency and reduce maintenance costs, Spin Grit and Spin Clean brushes are an excellent investment. With enhanced design and superior materials, they outperform traditional brushes, providing long-lasting, reliable cleaning solutions for a range of industrial needs.
