La lijadora eléctrica Ray de 7,6 x 10,1 cm de SurfPrep ofrece una potente potencia con 3 velocidades (4000, 7000 y 9000 RPM). Su motor sin escobillas de rodete exterior está fabricado con imanes más grandes, lo que proporciona un mayor par motor y ahorra energía en comparación con los motores de rodete interior. La placa de circuito impreso de la herramienta está completamente protegida con un sello de goma patentado que previene la contaminación ambiental. El ventilador patentado del cojinete del husillo prolonga la vida útil al mantener el motor y los cojinetes a una temperatura más baja. Las lijadoras eléctricas Ray ofrecen un ahorro energético significativo en comparación con las lijadoras neumáticas, además de dos programas de protección de anulación para prolongar la vida útil de la herramienta.

Aviso: El sistema de lijado SurfPrep está diseñado para funcionar como un sistema completo que conecta las lijadoras SurfPrep a los extractores de polvo de la misma marca. Los clientes han conectado con éxito lijadoras SurfPrep a extractores de polvo de otras marcas sin sufrir electricidad estática y con la función de encendido y apagado automáticos. Las lijadoras SurfPrep se conectan fácilmente a aspiradoras de bricolaje con las piezas que proporcionamos. Sin embargo, en estos casos, SurfPrep NO garantiza la ausencia de descargas electrostáticas. Esto suele ocurrir cuando las aspiradoras de bricolaje más económicas no cuentan con los componentes de conexión a tierra adecuados para evitar descargas electrostáticas. SurfPrep fabrica todas sus lijadoras y extractores de polvo con componentes conductores de estática.

3" X 4" Electric Ray Sander Manual

SurfPrep 3"x4" Electric Ray Sander | Brushless Electric Orbital Sander 

The SurfPrep 3x4 Electric Ray sander is a brushless electric orbital sander built for corners, edges, profiles, and surfaces where a standard round sander cannot operate. Three speed settings, patented cooling, and a form factor sized for the work that larger sanders cannot reach. Available with or without tool box. Ships to all 50 U.S. states and Canada. 

1. What Is the SurfPrep 3"x4" Electric Ray Sander? 

The SurfPrep 3x4 Electric Ray sander is a rectangular electric orbital sander built for corners, trim, profiles, and surfaces where a round sander is the wrong shape. It reaches into places a 5" or 6" disc cannot access without rounding off edges or losing surface contact. 

Key Features 

  • Brushless outer-runner motor, patented cooling, two override protection programs 
  • Three speed settings: 4,000 / 7,000 / 9,000 RPM 
  • Hook and Loop backup pad 
  • Central vacuum conversion piece: 1" female cuff for any central vacuum system 
  • Available with or without SPTOOLBOX-3X4 tool box 

2. Motor and Build Quality 

  • Brushless outer-runner motor: bigger magnets, more torque, no brushes to wear 
  • Patented spindle bearing fan keeps motor and bearings cooler during sustained use 
  • Rubberized seal on the computer board protects from dust and contamination 
  • Two override protection programs prevent conditions that shorten tool life 
  • Significant energy cost savings compared to pneumatic electric sanders over the life of the tool 

3. Speed and Control 

  • 4,000 RPM for fine finishing and between-coat passes 
  • 7,000 RPM for general surface preparation and sealer sanding 
  • 9,000 RPM for faster material removal on raw wood

7. Frequently Asked Questions 

What is the SurfPrep 3x4 Electric Ray sander used for? 

The SurfPrep 3x4 Electric Ray sander is a rectangular electric orbital sander for corners, edges, profiles, trim, shaker doors, and any surface a standard round sander cannot reach without rounding edges or losing contact. It is used in cabinet finishing, furniture making, and detailed woodworking applications. 

What speeds does the SurfPrep 3x4 Electric Ray have? 

The SurfPrep Ray sander has three speed settings: 4,000, 7,000, and 9,000 RPM. The lower setting suits fine finishing and between-coat passes. The mid setting handles most general sanding tasks. The high setting is for faster material removal on raw wood and initial prep work. 

Does the SurfPrep 3x4 Electric Ray come with abrasives? 

No. The electric sander does not include abrasives. It is available with or without a tool box. For abrasives, SurfPrep’s 3"x4" ProFoam pads and film and paper abrasive sheets are compatible with the Hook and Loop backup pad. 

Can the SurfPrep 3x4 Electric Ray connect to any dust extractor? 

The SurfPrep 3x4 Electric Ray sander includes a central vacuum conversion piece with a 1" diameter female cuff for compatibility with any central vacuum system. SurfPrep recommends pairing it with SurfPrep’s Vortex HEPA dust extractor system for guaranteed static-conductive performance. 

What is the difference between the tool box and no tool box variants? 

The tool box variant includes the SPTOOLBOX-3X4, which has a foam cutout for one 3"x4" sander and slots for organizing film and foam abrasives. The wood sander itself is identical in both variants. Purchasing a sanding system with the tool box saves 5% on the tool box price.
