C. Built for Heavy Loads

• Compressor-duty engineering supports:
• Frequent starts
• Long run cycles
• High torque loads
• Continuous shop-floor operation

D. Reliable & Durable Construction

• Rolled-steel housing resists:
  • Vibration
  • Heat
  • Harsh shop conditions
• Ball-bearing assembly delivers long service life
• High electrical efficiency minimizes excess heat

4. Why This Motor Stands Out

Perfect for Compressed-Air Systems

• The 3450 RPM speed is ideal for driving many compressor pumps.
• The service factor provides extra overhead during difficult startups.
• Consistent torque ensures reliable pressurization cycles.

Designed for Real-World Shop Environments

• Handles dust, vibration, and temperature changes commonly found in:
  • Automotive shops
  • Fabrication shops
  • Small industrial facilities
  • Home workshops

Easy Drop-In Replacement

• Standard frame size
• Foot mount
• Reversible wiring
• Simple power requirements (208–230V single phase)

Excellent Option for Equipment Upgrades

Examples of common upgrade scenarios:

1. Replacing a burned-out 5 HP compressor motor
2. Converting older equipment to higher torque output
3. Swapping out lightweight or budget-grade motors
4. Building a custom compressor or machinery setup

5. Practical Use Cases

Air Compressor Builds

• Retrofits on older cast-iron pumps
• Custom-built piston compressor rigs
• Upgrades to modern shop compressor systems

Small Industrial Applications

• Light-duty conveyors
• Material movers
• Belt-driven blowers or fans
• Smaller manufacturing machinery

Garage & Workshop Environments

• Automotive repair
• Tire/wheel shops
• Fabrication and welding shops
• Cabinetry or woodworking shops

DIY & Fabrication Projects

• Custom shop air systems
• Repurposed machinery restorations
• Equipment rebuilds where OEM parts are discontinued

6. Installation Advantages

Quick Installation

• Foot mounting allows simple bolt alignment.
• 56HZ frame matches many compressor bases.
• 7/8" shaft fits typical pulley bores.

Wiring Flexibility

Can be configured for:

1. CW rotation (clockwise)
2. CCW rotation (counterclockwise)

Electrical Compatibility

• Works with standard 208–230V single-phase power found in:
  • Small industrial buildings
  • Home garages
  • Agricultural shops
  • Mobile workshop rigs
