Improve your compressed air quality with the Quantum Blast QB-400CFM Industrial Air Aftercooler, a heavy-duty compressed air cooling and moisture separation system designed for abrasive blasting, industrial maintenance and high-performance pneumatic equipment.

Featuring a copper-tube heat exchanger, pneumatically driven cooling fan and integrated moisture separator, the QB-400CFM helps reduce compressed air temperature and remove condensed moisture before it reaches downstream equipment.

With a rated airflow capacity of 400 CFM, this industrial aftercooler is ideal for contractors operating compatible portable diesel compressors, dry and wet abrasive blasting equipment, and industrial compressed air systems.

NO EXTERNAL ELECTRICAL POWER REQUIRED – PNEUMATICALLY DRIVEN COOLING SYSTEM.

WHY CHOOSE THE QUANTUM BLAST QB-400CFM AFTERCOOLER?

1. HIGH-CAPACITY 400 CFM AIRFLOW

Designed for demanding compressed air applications, the QB-400CFM supports airflow requirements up to 400 CFM, subject to operating conditions and equipment compatibility.

Ideal for:

- Dry abrasive blasting and sandblasting
- Wet abrasive and dustless blasting
- Portable diesel air compressors
- Industrial surface preparation
- Rust and coating removal
- Construction and infrastructure maintenance
- Engineering and manufacturing workshops
- Industrial pneumatic equipment

A practical air treatment solution for contractors operating compatible 185 CFM, 265 CFM and 400 CFM compressor systems.

2. EFFECTIVE MOISTURE SEPARATION – APPROXIMATELY 80–90%

Moisture in compressed air is a common cause of abrasive flow problems, equipment corrosion and pneumatic system maintenance.

The QB-400CFM uses an industrial heat exchanger to cool compressed air, helping water vapour condense into liquid moisture.

The integrated moisture separator then removes approximately 80–90% of the condensed moisture under suitable operating conditions.

Key benefits:

- Reduces liquid moisture entering abrasive blast pots
- Helps minimise wet abrasive clogging
- Supports more consistent abrasive flow
- Reduces moisture-related equipment problems
- Helps protect downstream pneumatic components
- Supports reliable industrial operation

Actual separation efficiency depends on air temperature, pressure, humidity, airflow and operating conditions.

3. COPPER-TUBE HEAT EXCHANGER – EFFICIENT COOLING

The QB-400CFM incorporates a copper-tube heat exchanger designed to transfer heat from hot compressed air to the surrounding atmosphere.

As compressed air passes through the heat exchanger, forced cooling airflow reduces its temperature.

Benefits include:

- Effective compressed air cooling
- Improved condensation of water vapour
- Reduced temperature of downstream compressed air
- Efficient industrial heat transfer
- Suitable for portable compressor applications

4. PNEUMATIC OPERATION – NO EXTERNAL ELECTRICAL POWER

The cooling fan is driven by a pneumatic air motor, eliminating the requirement for an external electrical supply during normal air-driven operation.

This makes the QB-400CFM especially useful for mobile blasting contractors and remote worksites.

Key advantages:

- Air-driven cooling system
- No external electricity required
- Suitable for remote site applications
- Practical for mobile diesel compressors
- Convenient integration into suitable industrial air systems

The air motor requires an appropriate regulated compressed air supply and consumes air during operation.

5. INTEGRATED MOISTURE SEPARATOR

The built-in moisture separator helps remove condensed liquid water following the cooling process.

This reduces the amount of liquid moisture carried into downstream equipment.

Particularly beneficial for:

- Abrasive blasting pots
- Abrasive metering systems
- Industrial air tools
- Pneumatic machinery
- Industrial compressed air applications

6. BUILT FOR DEMANDING INDUSTRIAL APPLICATIONS

Designed for professional industrial operation, the Quantum Blast QB-400CFM combines robust construction, practical air-driven cooling and integrated moisture separation.

An excellent solution for contractors requiring improved compressed air moisture management without an external electrical supply.

IDEAL FOR ABRASIVE BLASTING CONTRACTORS

DRY ABRASIVE BLASTING

Moisture in compressed air can cause garnet and other abrasive media to become damp, resulting in inconsistent abrasive flow, blast pot blockages and unnecessary downtime.

The QB-400CFM helps reduce liquid moisture entering the abrasive blasting system, improving operating consistency.

WET ABRASIVE & DUSTLESS BLASTING

Suitable for compressed air preparation in compatible wet abrasive blasting equipment, including Quantum Blast RapidBlast™ systems.

Even in wet abrasive blasting, effective compressed air moisture management can support more reliable pneumatic operation.

INDUSTRIAL SURFACE PREPARATION

Ideal for suitable industrial blasting operations involving structural steel, fabricated components, machinery and equipment.

CONSTRUCTION & INFRASTRUCTURE

A practical solution for mobile contractors using diesel compressors on remote or industrial worksites.

ENGINEERING & INDUSTRIAL MAINTENANCE

Helps reduce moisture-related issues in compatible pneumatic equipment and compressed air systems.

WHY IS COMPRESSED AIR MOISTURE CONTROL IMPORTANT?

Hot compressed air leaving a compressor contains water vapour.

As compressed air cools, this moisture can condense into liquid water.

Without suitable aftercooling and moisture separation, condensed water may enter downstream equipment and cause:

- Damp abrasive media
- Blocked blast hoses and metering valves
- Inconsistent blasting performance
- Increased maintenance requirements
- Corrosion in compressed air equipment
- Unnecessary operational downtime

The Quantum Blast QB-400CFM helps address these issues by cooling compressed air and separating condensed moisture.

For applications requiring a specified pressure dew point or very low moisture content, additional compressed air drying equipment may be required.
