Yes, you can hook two compressors together to make a bigger reservoir of air. By connecting them with the correct fittings you can enable longer periods of use for your air tools however, it will also take your air compressor longer to get the pressure built up in two tanks rather than just the one.

How to connect two air compressors together?
If you have two air compressors and you’re now wondering how you can connect them together, simply connect a hose from the discharge coupler of their tanks on each to a tee manifold that will have a third connection where you can install a hose that will head towards your desired air tools.
Can I use two air compressors to feed one line?
Setting up the two compressors to feed one line will enable work to be performed more successfully with a high-demand air tool but, if the air tool exceeds the capacity of the two air compressors, then it would be time to consider a larger compressor for increased airflow if that tool is to be used a great deal.
Can You Run 2 air compressors in tandem?
Running 2 air compressors in tandem is a great idea for continuous air tool applications as the combined air system now has a higher CFM. It is also suitable for intermittent uses, in cases where specific air tools require a greater CFM than your singular air compressor is capable of providing.
How does a secondary air compressor work?
As air is drawn from the two compressor tanks to the air tool, compressed air from one tank will flow into the other tank and vice-versa, rather than all of it flowing down the airline to the tool. By installing a check valve in the line between the secondary air compressor and the tee of the primary compressor.

Can I add another tank to my air compressor?
First thing you'll need to do before starting to assemble your add-on tank is to release all the air and drain any condensation from your original air compressor. You should do this after each time you use your compressor anyway to avoid rot and air compressor explosions!
What is the advantage of a twin tank air compressor?
Twin-stack compressors have two air tanks, which means you can store more air so the compressor doesn't have to run as often. If you're a DIY-er, a twin-stack compressor is an excellent choice. They have enough power to run finish trim tools, such as brad guns and nailers.
What PSI should I set my air compressor?
between 70 and 90 PSIMost air tools require between 70 and 90 PSI. Any light-to-medium-duty air compressor can easily handle 90 PSI, but you always want the compressor to supply more flow than needed.
Does tank size matter air compressor?
The size of the compressor's tank will help to determine the amount of time that your air tools can run before the air compressor shuts off and has to be turned on again. If you only require intermittent use of air-powered tools, you won't need a compressor with a large tank size.
Can air compressor explode?
Air compressors can explode under certain conditions. The most common cause of air compressor explosions is excessive corrosion in the tank. If corrosion compromises the integrity of the tank, the pressure of the compressed air can cause the tank to rupture or explode.
How do tandem compressors work?
Tandem compressors include a plurality of compressors operating in parallel each typically receiving refrigerant from a common suction manifold, each separately compressing the refrigerant and typically delivering the refrigerant to a common discharge manifold.
What size air compressor do you need to run a sandblaster?
An air compressor which produces between 10CFM – 20 CFM is ideal for smaller sandblasting tasks. While a compressor which produces between 18CFM to 35 CFM is better for larger jobs where a more powerful experience is needed. While an industrial type of sandblasting needs a CFM of 50 – 100.
Will adding a tank increase cfm?
Use an Auxiliary Storage Tank Another method to help produce more airflow through your air compressor expands upon the idea in our first method, reducing the pressure on your regulator. As we explained in the previous examples, reducing the outlet pressure allows you to produce more airflow for a longer period of time.

What happens when the pressure in the hose to the air tool drops due to air use?
Once the pressure in the hose to the air tool drops due to air use and the primary compressor tank no longer keeps up , air will be drawn from the secondary tank as well , helping maintain the flow and pressure to the air tool .
What is a tee on an air compressor?
The tee is set up as: one leg of that tee is the supply from the primary air compressor, one leg of this tee is the supply from the secondary air compressor, and the last leg is where you install the air line to your air tools. If both air compressor tanks are full of compressed air when you start using your air tool, ...
Can air flow back into a secondary compressor?
However, when the secondary air is flowing, once again, air from that secondary tank could flow back towards the tank of the primary air compressor rather than down the line to the air tool, as air will always flow the path of least resistance. Solution? Another non-passing valve before the tee in the discharge coupler of the primary compressor, allowing air out of the tank, but not back into it from the other compressor.
Can compressed air be drawn from both air compressor tanks?
If both air compressor tanks are full of compressed air when you start using your air tool, compressed air will be drawn from both tanks… at least, in theory. The reality is, compressed air always flows through the easiest path from high pressure to low.
Can you connect two air compressors?
Connecting Two Air Compressors. There are sometimes good reasons for connecting two air compressors.

What does it mean when you run a compressor in a high duty cycle?
Remember that running a small compressor, or two joined together, in a high duty cycle means that there is no time for the air to settle as such a high moisture content can be expected. If the purpose is for spray painting then you may end up with drops of water in the finish.
Can you connect two storage tanks together?
You can connect both tanks together and this way you have double the storage. THe pumps will work independently and shut off when the maximum pressure is reached. Not big issues.
Does water reduce the lifespan of a compressor?
Water getting to the tool may reduce lifespan of the tool. Short term use of tools requiring higher CFM, go for it. Unless the compressors are vastly different just join the outlets and let the tank pressure balance between them, no one way valves needed. Short term use of tools requiring higher CFM, go for it.
Can you connect an unregulated tank to a water filter?
Yes connect the unregulated tanks, the reg and any water separator / filter / oiler should then be connected inline with the tool feed.
Can you use one way valves on a compressor?
Short term use of tools requiring higher CFM, go for it. Unless the compressors are vastly different just join the outlets and let the tank pressure balance between them , no one way valves needed.
The drain of the air compressor
Let’s drain all of the atmospheric moisture from the last tank before we begin disassembling it. It’s crucial because moisture in the tank might lead to damage. This rust can corrode the internal walls of the tanks, reducing their endurance and increasing the risk of an accident.
Connect the Tee after removing the Safety Mechanism
Remove the safety valve with an adjustable screw. Once you’ve located the safety mechanism, carefully remove it to avoid damaging the threads. Apply RTV silicone glue to the male side of the thread to prepare the brass tee.
Get the new air tank ready
The purpose of this stage is to fine-tune the fresh air compressor. Remove any linked instruments from the tank top initially, then connect the coupler to the installation detached point. Assemble the male thread of the 1/2′′ to 3/8′′ coupler with RTV glue.
How much pressure does an air compressor use?
If this adjustment is made, then the compressors would regulate the pressure at a discharge to between 110 and 125 psi through the changing loading conditions. This higher pressure, though, comes at a price. As a general rule of thumb, at around 100 psi, the power consumed by an air compressor increases by about 1 percent for every 2 psi in discharge pressure increase. Also, for every 1 psi increase in pressure, the flow consumed by unregulated compressed air users goes up by slightly less than 1 percent. This higher flow further increases the compressor power consumption by a level that depends on system characteristics.
What is the maximum pressure for an air compressor?
The higher pressure may also cause other efficiency issues. A common maximum pressure rating for air compressors is 125 psi. Perhaps as the filters in the system age and get clogged with dirt, system operators must increase the pressure at the compressor discharge to compensate. But if this is done, the compressor will exceed its rating, which would overload the motor and activate over-pressure protection. This higher pressure may also require the compressor to operate in modes such as modulating control that are inefficient at partial loads.
How much energy does a compressor consume?
Running three compressors all at 30% load may consume twice what one fully loaded compressor would consume while feeding the total flow. Implement this strategy with nine compressors and the energy bill goes through the roof.
What is the optimal control strategy for a compressor?
In any system, the optimal control strategy should be to keep all compressors except one fully loaded. The compressor that takes the partial load (called the trim compressor) would be selected by assessing which compressor has the best part load efficiency (load/unload, VSD or variable capacity control. Perhaps this decision could be made automatically.
Why are filters, regulators, hoses, and connectors used in compressed air tools and equipment?
Most often the filters, regulators, hoses, and connectors for compressed air tools and equipment are selected because they are a standard available size used in the plant. Installation is often done without regard to the actual peak demands of equipment connected at the far end of the hose. Connecting a large air-powered impact wrench at the end of a long piece of ¼-inch hose, for example, might result in extreme pressure differentials exceeding 50 psid and very poor tool performance. Upgrading component sizes to match the peak tool requirement might result in less than 10 psi pressure differential and pressures that better track the control point pressure at point P3 or P4.
How much pressure differential is needed for a dryer?
A real-world system has pressure differential across system components. At full load, there may be 4 psi across the filter, 6 psi across the dryer, 5 psi drop in the system piping and 15 psi drop across the filter, regulator, lubricator (FRL), hoses and connectors. This leaves the critical user with only 70 psi of air pressure during the worst-case scenario, system full load, when the compressor discharge pressure is being controlled at 100 psi. During light loading conditions, because the pressure differential drops with lower flow, the pressure at the critical user may float as high as 115 psi, depending on the local regulator setting.
What is the most important parameter in a compressed air system?
Pressure is the most important parameter in a compressed air system. If the level is not maintained above the minimum required pressure , then compressed-air-powered machines will start to malfunction, affecting production.

Why Connect Two Air Compressors Together?
- It’s possible your air toolhas a greater demand for compressed air than your air compressor can deliver, therefore you will be using the air tool at a greater rate than the compressor can actually supply to it. And, even though the air compressor is running, it cannot keep up with the demand of the air tool and so the tank pressure will keep dropping until there is not enough compressed air …
Adjusting The Pressure Switches
