Chicago Pneumatic QRS 7.5 HPD TM 7.5 HP Rotary Screw Air Compressor with Dryer, 60-Gallon Tank - PN 4152054785
Quiet, Continuous-Duty Compressed Air with Integrated Moisture Removal
The Chicago Pneumatic QRS 7.5 HPD TM Rotary Screw Air Compressor, part number 4152054785, combines quiet rotary screw performance, an integrated refrigerated air dryer, and a 60-gallon air receiver in one compact package.
Powered by a 7.5 HP industrial motor, this fixed-speed rotary screw compressor delivers 25.3 CFM at 145 PSI. Its tri-voltage motor can be configured for 208, 230, or 460-volt three-phase electrical service, providing installation flexibility for automotive, commercial, and light-industrial facilities.
The QRS 7.5 uses an advanced oil-injected rotary screw airend to provide smooth, consistent airflow with less vibration and pressure pulsation than a traditional reciprocating compressor. Its continuous operating capability makes it an excellent choice for businesses that depend on compressed air throughout the workday.
The integrated refrigerated air dryer helps remove moisture before compressed air enters the facility’s distribution system. This helps protect pneumatic tools, production equipment, controls, and compressed-air piping from moisture-related corrosion and contamination.
A sound-reducing enclosure limits compressor noise to approximately 66 dBA, helping create a more comfortable working environment. The included 60-gallon ASME/CRN air receiver tank provides compressed-air storage, stabilizes system pressure, and supports short periods of increased air demand.

Benefits of the Integrated Refrigerated Dryer
Atmospheric air naturally contains water vapor. Compressing that air concentrates the moisture, which can condense into liquid water as the compressed air cools inside the receiver and piping system.
The integrated refrigerated dryer helps reduce moisture and provides several potential benefits:
- Reduces water accumulation in compressed-air piping
- Helps protect pneumatic tools from internal corrosion
- Helps protect valves, regulators, and air-operated controls
- Reduces moisture reaching points of use
- Supports more consistent compressed-air quality
- Helps reduce moisture-related equipment maintenance
- Simplifies installation compared with a separate dryer
- Reduces external piping requirements
- Helps protect finished products and production processes
- Provides a compact compressed-air treatment solution
The dryer must be properly ventilated, drained, and maintained to provide dependable moisture removal.
Benefits of the 60-Gallon Receiver Tank
The included 60-gallon receiver provides stored compressed air that helps the system respond to short periods of increased demand.
Potential benefits include:
- Stabilizes compressed-air system pressure
- Provides stored air for intermittent demand
- Reduces frequent compressor starts and stops
- Supports short bursts of higher air consumption
- Allows compressed air to cool before entering the piping system
- Encourages condensate separation
- Reduces pressure fluctuations at pneumatic equipment
- Simplifies installation compared with a separate receiver
The receiver tank does not increase the compressor’s continuous airflow capacity. Sustained air consumption must remain within the compressor’s rated output of 25.3 CFM at 145 PSI.
Why Choose a Rotary Screw Compressor?
Longer Operating Hours
Rotary screw compressors are designed for extended operation and do not require the frequent cooling periods associated with many reciprocating compressors.
Lower Sound Levels
At approximately 66 dBA, the enclosed QRS 7.5 is substantially quieter than many open-frame piston compressors.
Smoother Air Delivery
Rotary screw technology produces a steady flow of compressed air with less pulsation and vibration.
Cleaner Compressed Air
Low oil carryover helps protect pneumatic tools and downstream equipment from excessive lubricant contamination.
Integrated Moisture Removal
The refrigerated dryer helps remove moisture before compressed air enters the facility’s piping system.
Compact Installation
The compressor, dryer, and receiver are combined into one space-saving package that simplifies installation.
Reduced Vibration
The rotary screw design and vibration-isolated assembly help reduce vibration transferred to the floor and connected piping.
Additional Air Treatment Recommendations
Although this compressor includes a refrigerated dryer, some applications may require additional air treatment to remove fine oil aerosols, particulate contamination, or odors.
Depending on the application, the system may require:
- Moisture separator
- Automatic receiver-tank drain
- Automatic dryer condensate drain
- Coalescing air filter
- Particulate air filter
- Activated-carbon filter
- Pressure regulator
- Oil-water separator
- Point-of-use air treatment
Automotive painting, sensitive controls, instrumentation, and critical production applications may require additional treatment beyond a standard refrigerated dryer.
Installation Considerations
The compressor should be installed indoors on a level, structurally adequate surface with adequate ventilation and service access.
Before installation:
- Confirm that the facility has 208, 230, or 460-volt three-phase electrical service.
- Verify that the electrical panel has sufficient capacity for the compressor and dryer.
- Confirm that total air demand is within the compressor’s 25.3 CFM capacity.
- Verify that piping and downstream equipment are rated for the operating pressure.
- Provide adequate ventilation around both the compressor and dryer.
- Prevent heated discharge air from recirculating into the cooling-air intakes.
- Keep all cooling and ventilation openings clear of obstructions.
- Install the required electrical disconnects and overcurrent protection.
- Verify the electrical requirements shown on the compressor and dryer data plates.
- Use properly sized compressed-air piping.
- Install a flexible connection between the compressor and rigid piping.
- Verify that the receiver and dryer condensate drains are operating correctly.
- Route oily condensate to an approved oil-water separator or disposal system.
- Maintain the manufacturer’s recommended service clearances.
- Confirm proper motor rotation before placing the compressor into service.
- Confirm all electrical and mechanical connections before operation.
Electrical installation should be completed by a qualified electrician according to the equipment instructions and applicable local codes.

Warranty Information
1-Year Standard Warranty
Eligible for up to 5 years of warranty coverage. Terms and conditions apply.
Basic Troubleshooting
Compressor Cannot Maintain Pressure
Check for compressed-air leaks, an open condensate drain, a restricted intake filter, incorrect pressure settings, or downstream demand exceeding the available 25.3 CFM.
Compressor Starts and Stops Frequently
Check for compressed-air leaks, rapidly changing air demand, incorrect pressure settings, or an open condensate drain.
Compressor Runs Hot or Shuts Down
Inspect room ventilation, cooler cleanliness, lubricant level, intake restrictions, ambient temperature, and the possibility of heated cooling air recirculating into the compressor.
Compressor Does Not Start
Check the electrical disconnect, incoming voltage, circuit protection, emergency stop, pressure settings, and any active fault condition.
Compressor Rotation Is Incorrect
Three-phase electrical connections may need to be corrected to achieve proper motor rotation. Disconnect power and have a qualified electrician correct the phase rotation before operating the compressor.
Excessive Moisture Downstream
Check dryer operation, the dryer condensate drain, receiver-tank drain, inlet-air temperature, ambient temperature, and airflow through the dryer.
Dryer Is Operating but Water Is Still Present
Inspect the receiver and dryer drains, downstream piping, operating conditions, and the possibility that moisture is entering from another part of the compressed-air system.
Dryer Does Not Start
Check the dryer power supply, disconnect, operating controls, ventilation, and alarm indicators. Consult the dryer operating manual before resetting an alarm.
Excessive Pressure Drop
Inspect the refrigerated dryer, compressed-air piping, isolation valves, regulators, hoses, and downstream air-treatment components for restrictions.
Excessive Oil Downstream
Check the lubricant level, separator condition, operating temperature, maintenance history, and whether the compressor is operating for extremely short periods.
Unusual Noise or Vibration
Shut down the compressor and inspect for loose panels, damaged isolation mounts, loose fittings, worn bearings, or other mechanical issues.
Electrical repairs, refrigeration-system repairs, internal pressure-system repairs, airend service, and major compressor repairs should be performed by qualified personnel.
