Because airflow decreases as discharge pressure increases, selecting the proper pressure configuration is important. Whenever possible, the compressor should be configured for the lowest operating pressure that reliably meets the requirements of the connected equipment.
Complete Tank Mounted Compressor and Dryer Package
The HBD 11 tank-mounted configuration combines three major components of a compressed air system into one integrated package:
- 15 HP rotary screw air compressor
- Air receiver tank
- Refrigerated compressed air dryer
This packaged design reduces the amount of equipment that must be separately installed and interconnected in the field while creating a clean, compact compressor-room installation.
For businesses upgrading from reciprocating compressors or installing a new compressed air system, the HBD 11 provides an efficient way to obtain compressed air generation, storage, and drying from a single packaged system.
15 HP Belt-Driven Rotary Screw Compressor
At the heart of the HBD 11 is Hertz's industrial belt-driven rotary screw compressor.
Rotary screw technology is particularly well suited for facilities with sustained or frequent compressed air demand. Compared with traditional reciprocating compressors, a rotary screw compressor provides a steady supply of compressed air and is designed for applications requiring longer operating cycles.
The Hertz HBD Series uses a durable screw block selected specifically for the required capacity of each compressor model.
New-generation rotor profiles are designed to reduce internal air losses and torque requirements, while an upgraded bearing design provides increased load-carrying capability.
Integrated Refrigerated Air Dryer
This HBD 11 configuration includes an integrated refrigerated compressed air dryer.
Compressing atmospheric air causes moisture contained in the incoming air to condense as the compressed air cools. Without proper treatment, this moisture can enter the compressed air distribution system.
A refrigerated air dryer helps remove this moisture before the compressed air is distributed throughout the facility.
Dry compressed air can help protect:
- Pneumatic tools
- Air cylinders
- Solenoid valves
- CNC equipment
- Air-operated machinery
- Distribution piping
- Paint and finishing equipment
- Production equipment
- Pneumatic controls
Combining the dryer with the compressor package simplifies installation and eliminates the need to find separate floor space for a standalone refrigerated dryer.
Integrated Air Receiver Tank
The HBD 11 is mounted on an integrated compressed air receiver.
An air receiver provides stored compressed air and can help stabilize system pressure during changing air demand.
The receiver also provides additional volume for short-duration demand spikes and can help reduce excessive compressor cycling.
Hertz specifies air tanks suitable for ASME standards, providing an industrial-quality foundation for the complete compressor package.
Premium IE3 Industrial Motor
The Hertz HBD Series utilizes a premium industrial electric motor designed for reliable compressor operation.
The HBD 11 is available in:
- 230V / 3 Phase / 60 Hz
- 460V / 3 Phase / 60 Hz
Hertz specifies IE3 efficiency, IP55 protection, and Class F insulation for the HBD Series motor.
These industrial motor specifications help provide dependable operation in demanding compressed air applications.
Wye-Delta Motor Starting System
The HBD Series uses a wye-delta motor starting system.
This starting arrangement is designed to reduce the electrical and mechanical impact associated with starting the compressor motor compared with a direct across-the-line start.
The result is a controlled startup designed specifically for industrial compressor operation.
Reliable Belt-Drive System
The HBD 11 uses a proven belt-and-pulley drive system.
Hertz incorporates an easy belt-tensioning design intended to simplify routine maintenance and reduce the time required to inspect, adjust, or replace drive components.
Belt-drive systems also provide straightforward access to commonly serviced drivetrain components.
Electronic Compressor Controller
The HBD Series is equipped with a microprocessor-based electronic controller designed to make compressor operation and monitoring straightforward.
The controller manages compressor operation and provides operators with convenient access to important system information.
Hertz designed the control system for dependable operation while allowing the compressor to be easily managed during normal day-to-day use.
Efficient Cooling System
Effective cooling is critical to rotary screw compressor reliability.
The HBD 11 utilizes an axial cooling fan directly connected to the main motor to provide efficient airflow through the compressor package.
Proper temperature management helps protect compressor components and maintain reliable operation during extended periods of compressed air production.
Service-Friendly Design
The Hertz HBD Series was designed with routine maintenance in mind.
Its internal component layout provides convenient access to consumable and service items, helping technicians perform scheduled maintenance without unnecessary disassembly.
Service-friendly features include:
- Easy access to maintenance components
- Quick-access protective covers
- Straightforward belt tensioning
- Serviceable belt-drive system
- Spin-on air/oil separator
- Easy-to-use electronic controller
- Compact internal component layout
Reducing the amount of time required for maintenance helps minimize compressor downtime and keeps the compressed air system available when it is needed.
Spin-On Air/Oil Separator
The HBD Series utilizes a spin-on air/oil separator design.
The separator is designed for straightforward removal and replacement, helping simplify routine compressor maintenance.
Easy access to service components can be particularly valuable for facilities performing their own preventive maintenance.
Compact All-in-One Compressor System
Combining the compressor, air receiver, and refrigerated dryer into one package provides a substantial advantage when equipment-room floor space is limited.
Rather than positioning three separate pieces of equipment and connecting them individually, the HBD 11 provides a professionally packaged system with a compact footprint.
The complete tank-mounted package measures approximately:
74" Long × 26" Wide × 63" High
This makes the HBD 11 particularly attractive for shops and industrial facilities that need approximately 50 to 70 CFM without dedicating excessive floor space to compressed air equipment.
Quiet Operation
The HBD 11 has a published sound pressure level of approximately 72 dB(A).
Its enclosed rotary screw design can provide a much more comfortable working environment than many traditional industrial reciprocating compressor installations.
For facilities where the compressor is installed near employees or production areas, reduced compressor noise can be an important consideration.

Is 15 HP enough for my shop?
That depends on your total compressed air demand.
The HBD 11 provides between 51 and 68 CFM, depending on operating pressure. Add together the CFM requirements of equipment that may operate simultaneously and include additional capacity for leaks, intermittent demand, and future expansion.
Compressed Air Advisors can help review your compressed air requirements and determine whether the HBD 11 is properly sized for your application.
