Rotary Screw Compressor vs Reciprocating Air Compressor
Choosing a stationary air compressor for your facility can be a difficult decision. Some common questions you will need to answer are: Where will the compressor be located? How much room is required? What is the total budget? How much maintenance is required? How much air is used throughout the day? How much does that air requirement fluctuate? How much pressure or PSI is required? How much horsepower is needed? What are the electrical requirements? Are there any noise restrictions?
The basic things to look at when comparing compressors are:
Horsepower – This is directly proportional to Cubic Feet per Minute CFM.
CFM - Cubic Feet Per Minute
PSI – Pounds per Square Inch must not exceed the requirements of pneumatic tools and equipment.
Tank Size – Size of the air reservoir is important for continuous operation and also determines the size of the overall compressor.
Dryers & After Coolers – Air treatment is important for removing moisture from compressors under heavy use.
Electrical Requirements – It is important to make sure your facility can handle the electrical requirements of the selected Compressor.
When comparing reciprocal air compressors with rotary screw compressors you will see many advantages to choosing the screw compressor. They are more compact, operate quietly, built for continuous operation and typically see less maintenance. The down side is the initial costs are higher. When you compare a 5 HP reciprocating air compressor at $1807 with a 5 HP rotary screw compressor at $3688 do the advantages out weight the initial cost?
Reciprocation Air Compressors
Ingersoll Rand 2475N5 - 5 HP – 175 PSI – 16.8 CFM - $1807 – With Air Cooler $2337
Ingersoll Rand 2545E10V – 10 HP – 175 PSI – 35 CFM - $2410 – With Air Cooler $3519
Ingersoll Rand 7100E15V – 15 HP – 175 PSI – 50 CFM - $3217 – With Air Cooler $4792
Rotary Screw Air Compressor

I have an air compressor that I used about 5-10 times per month. After each use, I empty the tank and leave the valve open to allow for the water to drain out. I really don't like having fill the tank prior to each use, but I have heard that this is a required step to protect my air tools. Is there something that I can do to keep the air in the tank and still protect my tools?

Keep up the good work.

I'm totally agree that the screw compressor is the better than the reciprocation air compressor. but how about the price ?

I have a screw compressor and I love it. But yes the initial cost is burdensome
