What is the Smallest Compressor for Cleaning Gun? | BrilliaTech SGS ISO BSCI Car Wash Tools

A cleaning gun (also called a Tornador gun) is one of the most popular tools in auto detailing. It uses compressed air to blast cleaning solution into hard-to-reach surfaces like car interiors, carpets, and vents. But to work effectively, it requires the right size air compressor.

So, what is the smallest compressor you can use with a cleaning gun? Let’s break it down.

Minimum Air Compressor Requirements for a Cleaning Gun

Most cleaning guns require:

Air Pressure (PSI): 70–90 PSI
Air Consumption (CFM): 4.5–6.5 CFM
Tank Size: At least 20–30 liters (5–8 gallons)

That means the smallest compressor you can use is usually a 20L / 5-gallon tank with 2 HP motor. Smaller compressors may work, but you’ll notice reduced performance and frequent stops for air refill.

The smallest air compressor that you can use effectively with a cleaning gun depends on the specific requirements of the cleaning gun you are using. Here are some general considerations to help you determine the appropriate compressor size:

Air Pressure (PSI): Most cleaning guns operate effectively within a pressure range of 60 to 90 PSI (pounds per square inch). Ensure your 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).

When selecting a compressor 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.

Why the Right Compressor Matters

Ensures continuous airflow without interruption
Provides enough pressure to atomize cleaning solution
Increases cleaning efficiency for car seats, carpets, and dashboards
Prevents wear on both the compressor and cleaning gun
