Custom Industrial Blower Packages for Pressure, Vacuum & Pneumatic Conveying
Carolina Material Technologies and Hardy Pro-Air help plants engineer custom blower packages around the required airflow, pressure or vacuum, layout, controls, noise limits, service access, and operating environment. Support includes new pressure and vacuum systems, pneumatic conveying blower packages, direct-drive upgrades, rentals, repairs, and troubleshooting.
A complete package engineered around the actual duty
The blower is only one part of a reliable air system. Hardy Pro-Air packages the blower, drive, filtration, silencing, protection, instrumentation, controls, and support structure around the conditions the equipment will face in service.
Typical package components and engineering considerations
Blower selection is based on the system — not horsepower alone.
Two packages with the same motor horsepower can perform very differently when pressure, vacuum, inlet temperature, elevation, pipe routing, filtration, controls, and operating range change. The goal is to deliver the required air at the actual operating point without unnecessary heat, noise, energy use, or maintenance.
Standard pressure blower package configurations
The following range summarizes the standard pressure package schedule provided for preliminary selection. Hardy Pro-Air can review the exact operating point and determine the proper blower, motor, accessories, discharge connection, and enclosure.
| Discharge Pressure | Listed Motor Range | Listed Design Airflow | Listed Airflow Span | Listed Discharge Connections |
|---|---|---|---|---|
| 3 PSIG | 3 HP | 100 SCFM | 31–135 SCFM | 2 in. MNPT |
| 5 PSIG | 5–40 HP | 100–1,000 SCFM | 25–1,075 SCFM | 2 in. MNPT through 6 in. ANSI flange |
| 8 PSIG | 7.5–60 HP | 100–1,000 SCFM | 22–1,075 SCFM | 2 in. MNPT through 6 in. ANSI flange |
| 10 PSIG | 30–75 HP | 400–1,000 SCFM | 300–1,075 SCFM | 4 in. MNPT through 6 in. ANSI flange |
Preliminary selection only: Available flow at a given pressure depends on the selected blower, speed, inlet conditions, elevation, temperature, gas properties, duty cycle, and system resistance. Final equipment should be selected from the complete application data.

Confirm required airflow, pressure or vacuum, operating range, duty cycle, ambient conditions, and the process the air system must support.
Review the System
Evaluate piping route, elevation, temperature, filtration, material characteristics, electrical supply, noise limits, and available footprint.
Select & Package
Choose the blower and motor, then configure the drive, silencers, relief protection, valves, connectors, controls, base, guarding, and enclosure.

Pressure vs. vacuum blower packages
Not every application needs the same blower arrangement. The right choice depends on where air enters the system, where material is picked up and discharged, operating pressure, maintenance goals, and the consequences of leakage.
| System Type | Best Fit | Common Uses | Key Design Questions |
|---|---|---|---|
| Pressure Blower Package | When air or material must be pushed from the blower side through the process. | Pneumatic conveying, aeration, agitation, combustion air, process air, and pressurization. | Required SCFM, discharge pressure, pipe route, conveying distance, elevation, temperature, operating range, and controls. |
| Vacuum Blower Package | When the system needs suction, pickup, vacuum conveying, or dust and vacuum collection. | Industrial vacuum, vacuum conveying, dust collection, pickup points, and process suction. | Required vacuum level, air volume, filter arrangement, inlet protection, material loading, pickup design, and discharge method. |
| Direct-Drive Package | When the plant wants fewer belt-related maintenance points and a compact drive arrangement. | Wastewater aeration, continuous-duty process air, and upgrades from belt-driven blowers. | Motor speed, VFD strategy, operating range, alignment, service access, process turndown, and energy profile. |
| Rental Blower Package | When temporary air capacity is needed without an immediate permanent-equipment purchase. | Outages, trials, emergency breakdowns, construction phases, bypass needs, and seasonal capacity. | Rental duration, required pressure or vacuum, electrical supply, controls, footprint, weather exposure, and connection requirements. |
Getting the operating point right matters.
A blower that is too small may not deliver the air needed at the required pressure or vacuum. A package that is unnecessarily oversized can increase energy use, heat, noise, bypassing, and equipment wear. Carolina Material Technologies can gather the field data and coordinate with Hardy Pro-Air to review the application.

Industrial blower package questions
What information is needed to size a blower package?
Typical sizing inputs include required airflow, discharge pressure or vacuum level, elevation, inlet temperature, piping layout, system losses, material being conveyed, desired conveying rate, duty cycle, electrical requirements, controls, sound limitations, weather exposure, and available footprint. Existing nameplate data and operating measurements are also helpful for replacement projects.
What standard pressure blower package range is shown on this page?
The submitted standard pressure package schedule includes configurations from 3 to 75 HP, design airflow options from 100 to 1,000 SCFM, listed airflow spans up to 1,075 SCFM, and pressure configurations of 3, 5, 8, and 10 PSIG. Final selection depends on the exact operating conditions and selected blower.
Can Hardy Pro-Air support both pressure and vacuum applications?
Yes. Hardy Pro-Air offers pressure blower packages, vacuum blower packages, standalone blowers, accessories, and custom packages for a wide range of air and material-handling applications.
Can a sound enclosure be included with the blower package?
Yes. Sound enclosures can be supplied for new packages or considered for retrofit applications. The design must maintain ventilation, control heat, provide service access, and account for indoor or outdoor installation requirements.
When should I consider direct-drive instead of belt drive?
Direct-drive is worth considering when the plant wants to eliminate belt changes and tensioning, reduce side-load stress, simplify the drive arrangement, or pair the package with VFD controls for process flexibility. The decision should still be based on the required speed and operating range.
Can an existing blower package be repaired, rebuilt, or upgraded?
Yes. Hardy Pro-Air offers blower repair and rotary airlock repair support, along with replacement blowers, controls, accessories, sound treatment, and direct-drive upgrade options. A system review can help determine whether repair, retrofit, or replacement is the most practical path.
