What Size Air Compressor is Needed for a Cleaning Gun?

Cleaning guns are powerful detailing tools widely used in auto workshops and car wash businesses. To achieve maximum efficiency, pairing your cleaning gun with the right air compressor size is critical. Let’s break down the requirements.

Why Air Compressor Size Matters for Cleaning Guns

Ensures consistent airflow for deep cleaning.
Prevents under-performance caused by low PSI or CFM.
Extends the lifespan of your cleaning gun.

Recommended Air Compressor Size for Cleaning Guns

PSI Requirements

Most cleaning guns operate best at 70–110 PSI. Anything below may reduce cleaning power, while excessively high pressure risks damaging surfaces.

CFM Requirements

On average, cleaning guns require 4–6 CFM (cubic feet per minute). This ensures steady airflow for continuous use.

Tank Size Considerations

Small jobs / occasional use: 20–30 liter (5–8 gallon) tank.
Professional workshops: 50–100 liter (13–26 gallon) tank for uninterrupted cleaning.

The size of the air compressor needed for a cleaning gun depends on several factors, primarily the air pressure (PSI) and air volume (CFM) requirements of the specific cleaning gun you are using. Here are some general guidelines to help you determine the appropriate size:

Air Pressure (PSI): Most cleaning guns operate effectively within a pressure range of 60 to 90 PSI (pounds per square inch). Ensure your air compressor can consistently provide air pressure within this range.
Air Volume (CFM): CFM (cubic feet per minute) measures the volume of air the compressor can deliver. The CFM requirement varies depending on the cleaning gun and the cleaning task:
- Low CFM Requirement: Some smaller cleaning guns with narrower nozzles or lower flow rates may work with compressors that deliver around 3 to 5 CFM.
- Higher CFM Requirement: Larger cleaning guns or those designed for heavy-duty cleaning tasks may require compressors that deliver 5 CFM or more.
Tank Size: A compressor with a larger tank size (e.g., 20 gallons or more) can provide more continuous operation without frequent cycling, which can be beneficial for longer cleaning sessions.
Portable vs. Stationary: Consider whether you need a portable compressor (smaller size, often with wheels) or a stationary compressor (larger size, typically more powerful but less portable).

To determine the exact size of air compressor needed for your cleaning gun, check the manufacturer's recommendations for the specific CFM and PSI requirements of the cleaning gun model you are using. This ensures that your compressor can supply enough air pressure and volume to operate the cleaning gun effectively for your intended cleaning tasks.

Choosing the Right Compressor for Your Cleaning Gun

When selecting, consider:

Horsepower (HP): 1.5–3 HP is sufficient.
Noise level: Quiet compressors improve workshop environment.
Portability: Smaller tanks for mobile detailers; larger for fixed stations.

FAQ – Air Compressor & Cleaning Gun

Q1: Can I use a small portable compressor with a cleaning gun?

Yes, but ensure it meets minimum 4 CFM at 90 PSI to avoid weak airflow.

Q2: Will a bigger tank improve performance?

Not directly, but it provides longer continuous operation before the motor cycles.

Q3: What happens if PSI is too low?

Cleaning results will be poor, and stubborn dirt won’t be removed effectively.

Q4: Are BrilliaTech cleaning guns compatible with any compressor?

Yes, as long as the compressor meets required PSI/CFM specifications.

Final Thoughts

The ideal air compressor size for a cleaning gun is 4–6 CFM at 70–110 PSI, with a tank size suited to your usage frequency.
