No, When an air compressor is built, it requires a motor or engine to power the process of producing air. The horsepower is not the only component of the equation. It has to be combined with the compressor pump that it runs to produce the air needed. The bigger the horsepower does not necessarily mean more air. Remember to keep your required cfm in mind. Horsepower does not make you work more efficiently, but horsepower working in unison with a quality pump that produces enough cfm for your needs. Make sure when shopping that you look for the running horsepower and not the peak horsepower you get at startup. Some manufacturers have falsely advertised or implied the peak horsepower to be the normal run horsepower. At start-up, there is a surge of power needed to start the motor and can be 1.5-3 times the amount of running power needed. This means the horsepower need for the motor peaks as well, but then drops back down to normal. Many of these manufacturers are involved in a class-action lawsuit for misrepresentation. They have used man’s machismo of “the more horsepower, the better” to their advantage to make sales. These aren’t cars we’re talking about!

Will an electric motor with more horsepower and more rpm hurt a compressor pump?


Electric motors seem to turn around 1125 rpm or 3600 rpm. The pulley size on the motor and pump must be adjusted to achieve the desired result without overheating /loading the motor. I have seen pumps turning from 800 to 1200 rpm using different pulley size on motor, motor hp and motor rpm. Some brands will turn same pump from 1200 to 3600 rpm depending on if was electric or gas motor. This will certainly shorten the life of the pump but will most likely work. Most turn an average of 1200 rpm for good balance of long life and good supply of air. Pump rpm is usually limited to the power of the motor. Cost effective match of 1.5 hp motor will turn pump about 1000 - 1200 rpm for about 5cfm. Rol Air 2hp motor turns 2 cyl pump about 1100 rpm for 10 cfm. Good luck

How much micro frard will i use for air compressor 0.5 hp


I don't believe there is a standard value for a specific horsepower rating. I have serviced and replaced plenty of these capacitors and the manufacturers say it is important to use only the value that the motor is originally supplied with. I have not seen it correspond to horsepower directly. Some motors use both a start and a run capacitor and I've never seen them identical. Horsepower listed ratings can vary wildly if it is not directly listed on the motor spec label. I believe .5hp corresponds to about 6 to 8 amps at 120 volts.

Compressor problems when filling tank


There should be a device called an "unloader " connected to the machines own switch. This releases the pressure from the compressor so it can start up without the resistance of the pressure in the tank.There should be a hissing noise when the machine stops, the sound of the air on the compressor side of a non return valve being released.

I would like to connect a pressure switch to the motor starter


hi! there, single phase compressor motor need a starting capacitor base on the rated capacity in horse power,you can check this on the tag of the compressor motor how many horsepower was indicated,it should be for single phase motor starting capacitor has a capacity of micro farads.for a 1 horsepower = 15 to 18 micro farads stating capacitor if you have more than 1 horsepower you can basically proportion the value of capacitor you need or ask the dealer how much capacitor you need on your motor the connection of pressure switch with a four terminal should be connected both on common line L1 and running capacitor line L2 .if you open the cover of pressure switch there are 4 terminals,2 terminals are connected when normally close or no pressure they connected on series connection on the common line one terminal connected to common line of the compressor and the other terminal on L1 to the pushbutton switch to L1 supply line.the 2 other terminals also connected in series withe line capacitors L2 to yhr power supply line.hope this will help you a lot.just rate my fix thanks a lot.
