PERFORMANCE AND DUTY CYCLE
This medium duty compressor is not designed for continuous use, spray equipment or heavy-duty air tools.
Attempting to use air tools with a requirement of over 238L/min Free air delivery will reduce the performance of the air
tool.
Pressure Cycle
The compressor forces air into a storage tank, increasing the pressure until it reaches an upper pressure limit at
which the compressor shuts off. When the compressed air is being used by a tool the pressure decreases until the
tank reaches its lower pressure limit, at that point the compressor turns on (via the pressure switch) to re-pressurize
the tank. This is the compressor pressure cycle.
Compressing air produces heat if the compressor is used outside its duty cycle and the heat is not managed the
compressor will be damaged. When the compressor turns off (via the pressure switch, after reaching maximum tank
pressure) it has time to cool down while the air in the tank is being consumed. When a tool consumes the stored air
quickly the time for cool down is reduced because the unit needs to restart to repressurize. If too short a time is
dedicated to the cool down phase the compressor can overheat and become damaged.
Duty Cycle
The ratio between the pressurization and cool down phases is called the Duty Cycle.
To determine whether we need a Trade or DIY compressor we must first understand duty cycles. The duty cycle is a
10 min test. How long over a 10min period is the pump/tool running for.
• 2 min on – 3 min rest – 2 min on – 3 min rest = 40% Duty Cycle.
• 5 mins on – 5 mins rest = 50% Duty Cycle.
• 1 min 30 sec on 8 mins 30 sec rest = 15% duty cycle.
