In double acting air compressor, air is admitted alternatively to both sides of the piston. If the air is cooled to temperature equal to the temperature of air at the inlet of the Ist stage cylinder, the inter-cooling is complete. The energy from the impeller is transferred to the air as the air flows through the machine and the pressure rise is primarily due to dynamic effects.
The following items are some of the most frequently asked air compressor questions and answers, courtesy of The Titus Company. An air compressor works by using electric power to create pressurized air that can then be released and converted to usable power for use in a number of applications, depending on your specific needs. It’s often a good value for you to add an air dryer to your air compressor system, as your air compressor can put a great deal of water into the compressed air system.
To offer pressures higher than standard 100 psig in a fixed speed, direct coupled drive air compressor, the compressor element must be. Choosing an air receiver that is smaller than the flow doesn’t make sense, because you will not have the necessary air to meet the needs of your system or end use. An air receiver with a capacity equal to demand isn’t a bad idea, but applications with variable demand may experience an increase in demand that the air receiver cannot accommodate.

air compressor questions and answers Related Question:
How long should an air compressor run for?
2.1 states that 1.5 psi pressure loss per 24 hour period is acceptable. We recommend that a compressor cycle no more than 4 times per hour to ensure maximum compressor life, so you are in very good shape with your system.”
Can you use an air compressor while its running?
If your operation needs it, they can run 24/7, but like a piston unit they run when a pressure signal turns them on. Unlike most piston compressors, most rotary compressors idle before they shut down completely.
What causes an air compressor not to work?
An air compressor problem could stem from one of many issues, such as an air leak, an oil leak or a broken part. In some cases, you might have insufficient pressurization or air flow. In other cases, the compressor might fail to start up or stop running as prompted.
What is duty cycle of an air compressor?
The duty cycle of a compressor dictates its longevity. The duty cycle of a compressor is the percentage of time that it can run before shutting off to cool down. If an application requires more than half-duty, then you need to know how much horsepower (HP), torque, and energy your air tools require.
What is a 100% duty cycle?
A 100% duty cycle simply means the compressor will deliver a consistent CFM and PSI the entire time the compressor is in use, which is different than being able to run continuously.
What happens if compressor runs continuously?
When damage occurs, the compressor can experience valve failures, causing the compressors to run constantly. If your reciprocating compressors are never turning off, you should investigate. If you have multiple compressors, your system should be set up so as not to allow constant operation.
Can air compressor stay?
With so much air under so much pressure, can you leave an air compressor full? The short answer is yes, it is perfectly safe to leave an air compressor full. So while under regular duty cycles, a full air compressor is standard, but during extended non-use, an air compressor should be drained and deactivated.
Can a compressor runs continuously?
Only those air compressors with a 100% duty cycle can run constantly at the specified pressure and flow. Running an air compressor beyond its duty cycle limit leads to premature wear and tear, higher maintenance costs and, at its most extreme, breakdowns which can shut down production.
How do you release air from a compressor?
Grip the ring on the valve with a pair of locking pliers. Turn the valve counterclockwise with the pliers. Open the valve only a little at first until the pressure lessens. Continue to open the valve more, allowing both air and condensation to release from the tank.
What are compressors used for?
Compressors are used throughout industry to provide shop or instrument air; to power air tools, paint sprayers, and abrasive blast equipment; to phase shift refrigerants for air conditioning and refrigeration; to propel gas through pipelines; etc.
Do air compressors have fuses?
Blown Fuse or Tripped Breaker Some air compressors have reset switches while others will have in-line fuses that need to be checked. To find them follow the line of power from the air compressor back to the outlet. If you find a blown fuse or tripped breaker go ahead and either replace the fuse or reset the breaker.
What are the parts of a compressor?
They consist of a piston, connecting rod, crankshaft, cylinder, and valve head. The air is compressed in the following manner: The valve head at the top of the compressor tank draws air in by the downward movement of the piston in the cylinder.
What is meant by 50 duty cycle?
If an air compressor has a 50% duty cycle, the compressor can provide air power for half of its total cycle time. Therefore, if the compressor cycles for a total of two minutes, you can draw pressurized air from the machine for durations of 60 seconds.
What is a continuous air compressor?
Continuous duty air compressors are designed to run for longer periods of time. They are ideal for air tanks, air horns, low riders, air tools and other situations where you have a frequent demand for air.
How long can a compressor run?
How long can you leave a compressor running? Depending on the size and type of compressor, air compressors can be left running anywhere from a few hours to 24 hours a day, seven days a week.
