Air compressor basics

Understanding your air compressor setup is critical for getting the best performance from the JetLine Pro System. Air tools are powered by airflow, not just pressure, and having the right combination of compressor, hose, and fittings makes a major difference in real world results.

Below is a simple breakdown of the key terms and setup considerations.

CFM (Cubic Feet per Minute)

CFM is the most important factor when running air powered cleaning tools.

CFM refers to the volume of air your compressor can deliver continuously. Higher CFM results in stronger propulsion, better whip movement, and more consistent cleaning performance.

Lower CFM compressors may still function, but performance will rely more on short controlled bursts of air rather than continuous operation.

General performance expectations:

  • Lower CFM (under 17 CFM) - Best used with short controlled bursts of air
  • Mid range CFM (17 to 23 CFM) - Good overall performance with controlled operation
  • Higher CFM (24+ CFM) - Excellent performance and continuous operation capability

For maximum WhipJet performance, higher CFM compressors allow sustained propulsion without the need to pulse airflow.

PSI (Pounds per Square Inch)

PSI refers to air pressure, not airflow.

While PSI is important, it does not replace CFM. A compressor can produce high PSI but still perform poorly if it cannot deliver enough airflow.

Most compressors used with the JetLine Pro System operate between 100 and 175 PSI. As long as the minimum pressure requirement is met, airflow becomes the primary limiting factor.

Minimum recommended pressure: 100 PSI

Piston vs Rotary Screw Compressors

There are two common types of air compressors used in professional cleaning applications: piston compressors and rotary screw compressors.

Piston Compressors

Piston compressors are the most common and are widely used in residential, mobile, and light commercial applications.

Key characteristics:

  • Lower upfront cost
  • Operate in on and off cycles using a storage tank
  • CFM output fluctuates as the compressor cycles
  • Best suited for intermittent tool use
  • Generally louder than rotary screw compressors

Rotary Screw Compressors

Rotary screw compressors are designed for continuous high demand airflow and are commonly used in industrial and fleet applications.

Key characteristics:

  • Provide continuous airflow without cycling
  • Maintain consistent CFM output
  • Quieter operation under load
  • Designed for extended run times
  • Higher initial cost and maintenance requirements

Rotary screw compressors offer the most consistent and predictable performance with the WhipJet and CamJet system and are ideal for long vent runs and continuous cleaning.

Electric Compressors

Electric air compressors may work in limited situations but are generally not recommended for optimal performance with the JetLine Pro System.

Most electric compressors are limited in sustained CFM output. While they may reach adequate PSI, they often cannot supply enough airflow to operate air powered cleaning tools efficiently. This results in reduced propulsion, slower cleaning, and increased reliance on short bursts of air.

Electric compressors may be usable for light duty or occasional use with short hose runs and controlled operation, but they are not ideal for professional or repeat cleaning applications.

For consistent performance, efficiency, and reduced operating time, compressors capable of higher sustained CFM output are strongly recommended.

Supply Hose Size Matters

One of the most overlooked causes of poor performance is supply hose diameter.

Small diameter air hoses restrict airflow even when the compressor itself is capable of higher CFM. This restriction can significantly reduce tool performance.

General recommendations:

  • Avoid long runs of 1/4 inch air hose
  • Use 3/8 inch or larger supply hose whenever possible
  • Keep hose length as short as practical

Larger hoses allow air to flow more freely from the compressor to the tool, improving responsiveness and overall performance.

Fittings and Restrictions

Quick connect fittings, reducers, and sharp bends all create airflow restrictions.

Each restriction adds pressure drop and limits the amount of air reaching the tool.

For best results:

  • Use high flow fittings
  • Minimize unnecessary adapters
  • Avoid excessive reducers between hose sizes

A clean unrestricted air path delivers noticeably better performance.

Using a Thumb Valve

A thumb valve allows the operator to control airflow directly at the tool.

For CamJet operation, use of a thumb valve is strongly recommended to manage propulsion, protect fittings and elbows, and allow controlled operation while viewing live camera footage.

For WhipJet operation:

  • With 24+ CFM, maximum performance can be achieved without a thumb valve
  • With lower CFM compressors, a thumb valve allows short controlled bursts of high pressure for improved propulsion and control

Final Notes

Every compressor setup is different. Performance will vary based on hose length, hose diameter, fittings, and overall compressor efficiency.
