What Works With Stealth 20 Gallon SAQ-12018 Air Compressor

What Size Air Compressor For Sprinkler Blowout

When it comes to choosing an air compressor for sprinkler blowout, mainly we have to consider CFM, the volume of air, and psi, the pressure of that air.

Here are some points to keep in mind before buying an air compressor for sprinkler blowout:

1- Constant Air Flow

2- Horsepower (HP)

3- CFM

4- PSI

5- Portability

6- Noise Level

7- Durability

Constant Air Flow:

Blowing out a sprinkler system requires a minimum of 2 minutes continuous air flow at 20CFM. Before buying an air compressor for sprinkler blowout, check out whether it can supply 20 CFM air for at least 2 minutes.

Horsepower (HP):

Horsepower (HP) is mainly the power that comes out of an air compressor motor. We all know that an engine is the heart of an air compressor. So, for blowing out sprinkler system, you have to choose at least a 4 HP air compressor.

CFM:

For blowing out sprinkler system, a minimum of 6 CFM is required to carry out operation smoothly. It can allow you to go for a large to small pipeline diameter for the zone by zone blowout.

The ideal air compressor for sprinkler blowout typically produces between 20 to 50 CFM at 50 psi.

In other words, take the GPM of each sprinkler zone and divide it by 7.5 to get a quick estimate of the required CFM. For example, a 150 GPM system divided by 7.5 would require 20 CFM of compressed air. If you plan to blow out multiple zones at a time, your CFM requirements will increase accordingly.

Lower CFM ranges are ideal for smaller pipes under 1”, while larger CFM ranges may be required for pipes larger than 1”.

PSI:

Regardless of the required CFM, the psi should always remain balanced for blowing out your sprinkler system. If an air compressor doesn’t produce enough air, water drops will remain in the pipes. On the other hand, if the PSI is too high, the compressed air can crack your sprinkler pipes and break sprinkler heads, causing permanent damage to the irrigation system.

Polyethylene pipe is more likely to break above 50 psi, while rigid PVC pipe can handle slightly higher pressures of up to 80 psi.

Portability:

For blowing out sprinkler system with an air compressor, you must have to pick a portable one. Because you may have to move your air compressor from one pipe to the other, so it is very important that you are using a portable air compressor to make your task convenient.

Noise Level:

We always recommend going for a quieter air compressor, specially for blowing out your sprinkler system. You can get some air compressors for lesser price from the market, but their louder noise will create much trouble. And, the high noise level is one of those troubles that can make your task hectic.

Durability:

Last but not the least; also make sure you buy the air compressor from a renowned brand, which is known for its durability, because you have to blow out your sprinkler system every year. If your air compressor is not durable, it will not be able to carry out the task next year. So always consider this point when picking up an air compressor for sprinkler blowout.
