Straight-Line Air Sander, 2300 RPM Dual Piston, 70×445mm Sanding Pad

Overview

This straight-line air sander delivers controlled, precision finishing power for automotive body work, woodworking, and industrial surface preparation. The dual piston motor provides smooth, reliable operation with minimal vibration—critical for achieving flat, even surfaces on large panels. Whether you're stocking a body shop, automotive refinish facility, or woodworking operation, this sander addresses the market gap between compact orbital palm sanders and larger belt sanding equipment, making it an essential complement to any finishing toolkit.

Key Features

• Dual Piston Motor: Twin piston design eliminates chatter and delivers consistent power output for smooth surface finishing
• Long Sanding Pad (70×445mm): Extended contact area ideal for leveling large panels, achieving flat body lines, and precision shaving on horizontal surfaces
• Quick-Action Paper Clamps: Heavy-duty clips secure sanding strips with minimal setup time—reduces changeover delays between jobs
• Automatic Release Trigger with Positive Stop: Prevents accidental activation; positive stop action ensures controlled engagement
• Vibration-Free Performance: Balanced internal design minimizes operator fatigue and delivers superior surface quality
• Low Noise Operation: 91dB—acceptable for typical shop environments
• Dust Management: Integrated dust tube and collection bag included; keeps work area clean and improves visibility
• Ergonomic Grip Design: Black spherical palm knob and rear handle provide secure, comfortable control during extended use

Business Advantages

Profit Margin Opportunity: Straight-line sanders command consistent demand from body shops and refinish facilities but face less competition than orbital models. Positioning this alongside your palm sander inventory creates a tiered finishing solution—driving higher attachment rates and customer basket value.

Durability & Reliability: The dual piston mechanism is proven in professional settings. Minimal maintenance (daily oiling) keeps warranty claims low and customer satisfaction high.

Market Gap Filler: Many resellers stock only orbital or belt sanders. This straight-line model fills the critical gap for flat-surface finishing, allowing you to serve shops that currently outsource this work or use suboptimal equipment.

Bulk Order Advantage: Professional shops typically purchase multiple sanders for different finishing stages. Competitive bulk pricing on this model positions you as a one-stop finishing solution supplier.

Application Reality

This is not a speed sander—10,000 RPM is moderate and intentional. The long pad and lower speed produce controlled, flat results on:

• Automotive body finishing: Leveling primer, blocking paint imperfections, preparing for final coats
• Woodworking: Long-grain sanding, leveling veneers, precision surface prep
• Industrial panel work: Flat metal or composite surfaces requiring uniform finish
• Precision shaving: Removing old paint or material with accuracy, not speed

Shops needing aggressive material removal use belt sanders; those needing fine detail use orbital models. This tool owns the middle ground—and that's where consistent, profitable work lives.

Stock Confidently

The dual piston reliability, included dust collection, and balanced design mean fewer returns and higher customer retention. This is a workhorse tool with straightforward operation and proven longevity in professional settings. Distributors stocking this model typically see steady repeat orders from established shops upgrading from consumer-grade equipment.
