A safe alternative to the seismic airgun
Substitute for Air Compressor Oil Hydraulic Oil Hydraulic oils have certain characteristics that make them suitable for use in air compressors. Such as — They have low viscosity at low temperature. Viscosity indicates how fluently fluid flows without resistance.
Low-viscosity fluids have less density and they can flow more fluently. Because of having lower viscosity, they flow more fluently than other oils of higher viscosity, even in a low-temperature area. You can use hydraulic oils in your compressor in case you have a simple crank-case type pump in the compressor. In winter, 10W hydraulic oils are suitable to use. Because more than this weight can make the oil get jammed.
In summer you can use 30W hydraulic oils. Hydraulic oils can be used as a good quality lubricator in your compressor. Hydraulic oils are immune to oxidation. So, they can also protect your compressor from rusts. Finally, air compressors are made with sealant materials.
Hydraulic oils are compatible with such materials. So using hydraulic oils have a plus point in this case as well. They are usually used in car transmissions because they can perform such tasks. These tasks include Working as a hydraulic medium. Keeping the parts free from deposits.
Cooling the parts. Resisting breakdowns when the machine is under stress. Reducing wear and friction. Although these are required in a car transmission, air compressors also need these because of having the same stresses. For example, air compressors also require cooling of parts, and they also need less friction and wear, etc. To perform the above-given tasks most of the ATFs are formulated with enhanced additive packages and robust base oils.
They contain antioxidants, anti-wear agents, demulsifiers, and detergents. Credit: Wikimedia Commons Here are a few benefits you get from the ATFs — Your air compressor will definitely produce heat while running.
So, you have to use a fluid that can resist breakdowns when the heat is present. ATFs have the ability to do that.
This is why you can use ATFs as another substitute for air compressor oil. While resisting the breakdowns, ATFs will produce deposits in the areas that have high heat. To reduce these deposits, ATFs contain detergents. This makes the internal parts cleaner and free of deposits. ATFs contain antioxidants that are also necessary for the compressor. When the gas of the compressor is compressed, it causes oxidation. This leads to premature oil failure. The antioxidants in ATFs can resist such degradation.
So far it looks like ATFs are really good as a substitution, right? But there are some drawbacks that you need to consider. For example — Most ATFs can be incompatible with your air compressor. If this happens, then you should not use that ATF in your compressor. The detergents that ATFs contain can make the motor of your compressor get damaged quicker than you expect. Usually, the compressor manufacturer recommends a particular oil for you to use in the compressor during the warranty period.
If you use ATFs and fail, then the warranty may not help you to recover the damage. Synthetic Oil Synthetic oils are made with a synthetically created base or artificially made chemical compounds. Synthetic oils are more refined as they go through a lot of processing so that they can be used for a specific case only.
As a substitute for compressor oil, synthetic oils are one of the best options. Synthetic oils enable your compressor to work in both low and high temperature. So they can protect your compressor from overheating. Credit: Pixabay On top of that, synthetic oils can reduce noise. Thus your compressor will perform more quietly and smoothly if you use synthetic oils.
For a cold environment, it is recommended that you use 20W oils. There is only one drawback of using synthetic oils. I have already said that synthetic oils are made for particular cases. So, you have to make sure that the synthetic oil you have is for air compressors. Otherwise, your compressor may get damaged. This is not completely true. OEM lubricants are usually recommended by the manufacturers so that you do not go for other substitutes.
If you purchase OEM lubricants than the manufacturers get the benefit. There is only one thing you should be aware of. While choosing a Non-OEM lubricant, keep in mind that the properties of that lubricant should be compatible with your compressor. Say your air compressor leaked all the oil and you need to run it immediately, in such emergency, you can use substitute oil. What can be used as compressor oil? Compressor oil some certain properties.
If you find a lubricant or oil that has these properties, you can use it for your compressor. These properties are — Viscosity Viscosity can be referred to as the weight of oil.
The higher the viscosity the higher will the density. So a high viscosity oil will be thicker than an oil with a low viscosity. In an air compressor, 20W or 30W are generally used based on the viscosity.
So, if you find a lubricator that has this weight as viscosity, you can use this oil for your compressor. Additives The additives that are used in oil can be both helpful and harmful. For example, detergent is an additive used in some oil. It can make the interior of a machine cleaner by reducing deposits. Detergents of motor oil create foam in the pump of your air compressor can reduce the lifespan of the motor too.
So, it is up to you to choose either you want a cleaner interior of your compressor or a longer lifespan of the motor. Change of Temperature The viscosity of oils can change due to the change in temperature. This is due to the molecular cohesive force in the oil. So, you have to match your environment temperature and the viscosity while choosing an oil for your compressor. For example, if you are in a colder area, lower weight of viscosity like 10W or 20W is better to use.
On the other hand in a warmer environment 30W is better. Any oil that has the characteristics above will get the job done for you. Is air compressor oil the same as hydraulic oil? Though hydraulic oil is a good air compressor oil substitute, they are not the same. Hydraulic oil has more additives than air compressor oil.
3 Things to Use as Air Compressor Oil Substitute
A safe alternative to the seismic airgun 16 Jun The use of seismic airguns in offshore oil exploration has proved controversial, with some claiming that they may interfere with natural patterns of animals such as whales and dolphins.
Now Geokinetics has completed the second successful deployment of its AquaVib Marine Vibrator, a competitor to the seismic airgun with a much lower decibel footprint. Could it solve this problem and add several other important advantages along the way? Share Article Airguns have been an essential part of subsurface exploration in the oil and gas industry for over fifty years.
By sending seismic waves down through the sea, they can collect data based on how these are reflected back allowing the construction a map of what lies below the sea floor. Little change has been made in the use of the technology throughout the years — until now. Geokinetics has successfully completed the second deployment of its new alternative to the airgun, the AquaVib. The marine vibrator works on a similar principle as the airgun, but with some key differences, especially regarding the sound level.
All of the energy of the expanding air bubble is released over a time span of about 50 milliseconds. The added subsea noises are thought to damage the hearing of mammals in particular, disrupting communication patterns and detrimentally changing their behaviours.
The second key difference is the size of the AquaVib, which is a fraction of the cumbersome airgun. During the oil boom, companies could afford to invest heavily in projects in deep waters, which have a far slower rate of return but are more profitable. Following the oil price crash in , many companies have to take a different approach. Shallow waters are traditionally unexplored for a number of reasons.
This means operations often take longer and cost more than in the deep sea. They are designed to work in groups of around a dozen units, on autonomous catamarans which can survey the seafloor in areas of water as shallow as 2m. Does the airgun hurt marine life? Various environmental organisations, such as Oceana, believe blasts of high-decibel sound waves of damage animal hearing and change their behaviour. In particular, there has been concern about the effect on baleen whales. This marine superfamily includes blue and humpback whales, which rely on sounds to communicate over hundreds of miles.
Impeding this communication, both by adding to the mix of subsea noise and damaging the hearing of creatures closer to blasts, particular through impulses of over decibels, means they cannot communicate as they normally would, potentially forcing them to change their foraging paths and breeding habits.
This concern is backed by publications such as Impacts of anthropogenic noise on marine life: Publication patterns, new discoveries, and future directions in research and management from Using six case studies it analyses the effect of underwater noise from a number of sources including seismic surveying. But the effects of the airgun have been contested, and the U. Geokinetics did not design the AquaVib to counter the environmental concerns; however it does provide an alternative that it claims poses no danger to marine mammals, such as whales.
The argument is hampered by the lack of long-term research. The ocean is vast, as is the range of animals within it, many of whom we know very little about.
Therefore fully understanding the extent of the effect of seismic activity is a complex and difficult task. Financing concerns Geokinetics says that the AquaVib is now ready for production, but financing may hold it back. It has a jump on the market, and the fears associated with the airgun are still likely to encourage demand for alternative sources of data.
The best gun oil: Why you shouldn’t skimp on cleaning your gun

While most ATF fluids have some detergents in them, they are designed to go long distances without being changed. This makes them better suited for use in compressors.
Transmission fluid has emulsifiers to help it handle the condensation that can build up inside a compressor head. You should be careful not to mix oil types if there is a different oil in your compressor; empty that before adding transmission fluid. Also, be aware of warranty concerns. Some brands are very restrictive on which oils you can use during the warranty period. If you add the wrong brand or type of oil, it can cause you to void your warranty.
Compressor Oils My favorite option is to use a dedicated compressor oil. This seems to deliver the best results.
Compressor oils do not cost much more than engine oils do. It may be cheaper than some of these alternative options that we discussed. If you can find synthetic oil, that is the best idea. Synthetic compressor oils can go up to 1, hours between oil changes. For the heavily used air compressor, this can save you a lot of time in maintenance.

On the other hand, your gun has a large surface area and is regularly exposed to wind, rain, blood, sweat and, occasionally, tears. All this conspires to produce the greatest single danger to your gun — rust. Many general-purpose oils — and indeed some budget gun oil — are some variant of bearing oil, which has a very high slip coefficient.
These products are excellent for use in cars, bikes and even aeroplanes, but have little practical application in the average shotgun. This means there is really no justification for letting the can of 3-in-1 anywhere near your firearm.
Though the formulation of WD does effectively drive out contaminants and moisture, it also strips away other oils and greases. A liberal dose prior to storing a gun stock-down in the gun safe will result in the surplus chemical dribbling down and into its action, eventually removing vital lubrication from places behind the sideplates where you cannot easily replace it.
Damage to the soft-solder that holds the rib to the barrel is also possible over time and, in extreme cases, this can result in the rib delaminating from the gun.
