Hertz HPC 7.5 E Air Compressor | 7.5 HP Silent Oil-Injected Reciprocating Compressor | 31 CFM @ 100 PSI | 175 PSI Max

Quiet. Powerful. Built for Professional Performance.

The Hertz HPC 7.5 E is a premium industrial-grade reciprocating air compressor engineered for businesses that need serious compressed air performance without the excessive noise commonly associated with traditional piston compressors. Delivering 31 CFM at 100 PSI and a maximum pressure of 175 PSI , the HPC 7.5 E is ideal for automotive repair shops, manufacturing facilities, woodworking operations, fabrication shops, CNC equipment, tire service centers, and other demanding commercial applications.

What sets the HPC 7.5 E apart is Hertz's patented Silent Air System , which reduces operating noise by more than 50% compared to conventional reciprocating compressors. Whether installed near technicians, production areas, customer-facing service bays, or workstations, the HPC 7.5 E helps create a more comfortable and productive work environment while delivering the airflow your operation requires.

Industry-Leading Quiet Operation

Traditional piston compressors are known for excessive noise, but the Hertz HPC 7.5 E was designed differently.

The patented Silent Air System utilizes a multi-stage air filtration and baffling process that significantly reduces intake and operating noise without sacrificing performance. The result is a compressor that delivers industrial airflow while maintaining a quieter work environment.

Benefits of the Silent Air System:

• Reduces operating noise by more than 50%
• Improves employee comfort and communication
• Ideal for shops with compressors located near work areas
• Minimizes workplace noise pollution
• Maintains full compressor performance while operating quietly

Built for Long Life and Continuous Reliability

At the heart of the HPC 7.5 E is Hertz's patented pressure-lubricated pump design , which continuously delivers lubricant to critical internal components. Unlike splash-lubricated compressors, pressure lubrication reduces wear, improves cooling, and significantly extends pump life under demanding operating conditions.

Additional durability features include:

• Pressure-lubricated industrial compressor pump
• Heavy-duty B-style drive belts for smooth operation
• 100% brass valve construction
• Premium-grade pressure switches
• Heavy 16-gauge steel belt guards
• Magnetic starter with overload protection
• Powder-coated ASME-certified receiver tank
• 200 PSI tank rating for added durability and safety

Maintenance Made Easy

The HPC 7.5 E is designed to reduce routine maintenance requirements while maximizing uptime.

A factory-installed 110-volt dual-timer automatic tank drain automatically removes condensate from the air receiver, eliminating the need for daily manual draining and helping protect the tank from internal corrosion.

Additional maintenance-friendly features include:

• Automatic condensate removal
• Simplified belt inspection and adjustment
• Easy-access service components
• Two-turn belt tension adjustment system
• Reduced vibration for extended belt life

High Airflow and High Pressure Performance

With 31 CFM at 100 PSI and a maximum pressure rating of 175 PSI , the Hertz HPC 7.5 E provides dependable compressed air for demanding industrial and commercial applications.

The higher operating pressure gives technicians additional power for air tools and equipment that perform better at elevated pressures.

Common Applications

• Automotive repair facilities
• Tire shops and truck service centers
• Manufacturing operations
• CNC machinery
• Woodworking shops
• Fabrication facilities
• Paint booths
• Assembly stations
• Pneumatic production equipment
• Maintenance departments

Flexible Power Options

The Hertz HPC 7.5 E is available in multiple voltage configurations, allowing it to fit a wide variety of commercial and industrial facilities.

Available voltages include:

• 230V Single Phase
• 208-230V Three Phase
• 460V Three Phase

This flexibility makes the HPC 7.5 E an excellent choice for both small businesses and larger industrial operations.

Technical Specifications

Why Choose the Hertz HPC 7.5 E Instead of a Standard Piston Compressor?
