Air compressors are the most available equipment that undergoes major explosions in daily life. Excessive compression and working leads to damage if you don’t monitor and examine the air compressor thoroughly and its tools.
Multiple compressors work on automatic draining, which drains the excess air out of the compressor after usage. But some don’t and require more care and measures. Draining can help prevent your machine from any corrosion and rusting.
The question is, Is it necessary or not? Well! It differs according to the machine, and to know whether it is necessary to drain the air compressor after every use or not, we have to go through the article. Is it necessary to drain air from an air compressor after every use?
Should I drain the air compressor after every use?
The approach to this question is simple, YES, you need to drain air from an air compressor after every use. It is the most critical step that often gets confused; indeed, a necessary thing.
Basically, there are two types of drainages that take place in the compressor; drainage of air and drainage of water. Here we are covering the drainage of air:
As I have mentioned above, some compressor has this automatic drainage feature, but some don’t, so for those, you have to do it manually, but the process is quite simple. That is the topic for some other day.
The mechanism on which air drainage takes place
1. Production of sound & pressure build-up:
Anyhow, in an air compressor, right after the compressor has stopped working or when you switch off the air compressor, it immediately starts producing hissing sounds, an indication of the drainage of the air from the compressor. It is primarily used to signal that the air pressure is set to release and drain the compressed air.
There is a little process behind the drainage where there is a valve between the compressor and the tank that got filled. The tank does not drain the air because doing so will cause the compressor to start all over again.
Now, the compressed air is drained typically so that the energy stored does not exceed its limit; if this doesn’t happen, it will cause damage to the compressor. That’s why you need to drain air from the air compressor after every use.
2. Generation of heat & steal case compressor:
In this way, if you have an air compressor in which the cylinder is made of steel, it will definitely need to get drains after every use. I cannot emphasize enough on differences between the compressors and how their function varies too. It can be any kind of steel, cast iron or mild steel, etc.
The compression produces heat, and the normal drainage helps ensure that the compressor doesn’t rust or corrode.
If the size of the outlet hole is smaller, it will automatically increase the heat production because of slow heat release. If you don’t drain the air, it will accumulate at the bottom of the tank and can cause corrosion.
3. For minimum usage:
When using your compressor daily or weekly life purposes, in conditions like cleaning garages and stores to apartments or for using it in shops and even for filling air tools, you need to drain the air compressor daily; if not, it should be drained once in two days. Otherwise, the accumulation of debris will explode.
Primary reasons to drain air compressor
There are three primary reasons behind the drainage of air compressors every day.
1. Prevention from weathering:
Air compressors are prone to weathering, deteriorating, etc. As it stores the maximum amount of air pressure inside it, the chances of damage also increase. It is advised to drain the air compressor after every use for the durability of the compressor.
In factories or shops, where the usage is excessive, and care is not provided enough, different consumption and contact with other surfaces lead to impairments.
2. Prevention from moisture
Because of the compressed air in the compressor and the accumulation of the air pressure, it contains water droplets that travel from the outlet to the hose pipe.
The water droplets are like the slow poison for the air compressor that will affect the machinery entirely from the moisture, so better to drain the air compressor after using it.
Most air compressors have a drainage valve, through which you can quickly drain it and can avoid any kind of inconvenience. Although the drainage doesn’t require it to be done daily, if you are overusing it, you must realize to drain it out.
If you don’t consider this a practice, it will leave you empty-handed. In the case of compressors, the maintenance services cost you more than buying a new one. So better to make an effort than to put in money.
