An air compressor trailer is a type of mobile air compressor. Mobile air compressors are often referred to as portable air compressors. They are designed for ease of movement on the worksite or to be used in combination with different types of machinery. Air compressor trailers are typically pulled behind a vehicle or piece of equipment. They often feature two wheels and a coupler that connects to a pintle hitch or ball hitch on the trailer side.
Air compressor trailers are essential for jobs that require a consistent supply of compressed air. Some common applications include road and waterway construction, pile and trench excavation, rock and soil drilling, bridge deck and pavement sanding, creating inflatable talkons for trench dewatering, operating hand and power tools, and driving air hammers and drills.
There are various types of air compressor trailers:
Petrol/Diesel Air Compressor Trailer:
Petrol and diesel-powered air compressor trailers are common types of portable air compressor trailers. They work the same way, but diesel air compressor trailers have better fuel efficiency and fewer emissions. Diesel air compressor trailers are the first choice for heavy-duty work.
Direct Drive Air Compressor Trailer:
Direct drive air compressor trailers feature an air compressor mounted directly to the engine's crankshaft. The leading benefit of a direct drive compressor is fewer moving parts compared to gear or belt-driven compressors, which can reduce maintenance needs and increase reliability. However, one downside to a direct drive compressor is that the motor must run at higher speeds, which can increase noise levels. Another drawback is that motor speed and compression speed are directly linked, which can give less compression control.
Belt-Driven Air Compressor Trailer:
Belt-driven air compressors use a belt to connect the motor to the pump. Unlike direct drives, the motor's speed must be less than the pump's, which can allow the motor to use less energy. This can include using less energy to create more energy. One benefit of a belt-driven air compressor trailer is that it can be smaller and lighter. It is also known that belt-driven compressors typically run on quieter fur than direct drives.
Electric Air Compressor Trailer:
Electric air compressor trailers are suitable for use indoors or other jobs that require a quiet operation. They are designed to run on battery power and can be charged in various ways, including solar, shore power, or vehicle while driving. This gives the user more flexibility on the job site. Electric air compressor trailers are eco-friendly and reduce carbon emissions.
Choosing the correct air trailer compressor largely depends on what it will be used for and how much compressed air is needed. These are some key air trailer compressor specifications:
Flow Rate
The amount of compressed air the trailer can produce will depend on the flow rate, usually measured in cubic feet per minute (CFM). Flow rates vary from 1-125 CFM for the three types of air trailer compressors. It is essential to know how much compressed air is needed before selecting a flow rate.
Pressure
The amount of pressure measured in pounds per square inch (PSI) that the trailer can produce will determine how effective it is when doing different jobs. The pressure ratings for air trailer compressors range from 90 to 150 PSI. It is vital to know the pressure job requirements before selecting a compressor with lower or higher PSI.
Motor Power
Motor power for an air compressor trailer is indicated as horsepower (HP). It helps indicate the overall performance of the trailer, but it is also essential to consider other factors that influence the trailer's performance. The HP ratings of air trailer compressors vary from 3-15 but often lower because the trailer is towed by a motor vehicle.
Tank Size
The tank on an air trailer compressor is usually referred to as a reservoir. It stores compressed air and varies in capacity from 10 to 90 gallons. A tank with a larger capacity is favorable as it can supply compressed air for a longer period of time without stopping to recharge the compressor.
Dimensions and Weight
A compressor with low weight is preferable because it is easier and more fuel efficient to tow behind a vehicle. Or, if it is mounted on a vehicle, it can more easily carry the weight with a low likelihood of imbalance or reduced performance. Dimensions are important if the object being towed or transporting is large. It affects storage space and clearance height.
All trailers, big or small, need regular maintenance to prolong their life and ensure they perform well while avoiding breakdowns. Some of the essential maintenance tips for an air trailer compressor are as follows:
Weekly Inspection
An air trailer compressor benefits from weekly inspections to ensure the parts are functioning optimally. Checking all the bolts and fasteners helps identify loose parts that can cause damage or create unsafe conditions when operating the trailer. Inspecting the electrical components keeps the wiring and connections secure, keeping the air compressor functional.
Fluid Replacement
Replacing the oil in the air trailer compressor ensures the moving parts are lubricated, lowering friction, reducing heat, and minimizing wear and tear. The air from the trailer may contain some moisture. Draining the condensate from the air storage tank prevents rust and damage to downstream equipment.
Filter Cleaning
The air filter on the trailer compressor stops dust and dirt from entering and protects internal parts. Cleaning or replacing the air filter preserves air quality. The oil filter removes impurities and contaminants. Cleaning or replacing the oil filter preserves the longevity and efficiency of the compressor.
The usage of trailer-mounted air compressors cuts across many industries and sectors.
Construction Sites
One of the major uses of the air compressor trailer is in the construction industry. Compressed air gives power to pneumatic tools like drills, nail guns, jackhammers, wrenches, etc. (which are popularly used in construction projects) to function properly. In addition to powering tools, the trailers serve as a source of pressurized air for other needs - for mixing concrete, removing debris, or for any other application that requires it.
Mining Operations
Trailer air compressors provide a source of power for a wide range of equipment used in the mining industry. Some of these include drills, mineral hoppers, and conveyor belts, to mention but a few. The mobility feature of trailer air compressors makes it very easy to set up in different locations within the mine.
Automotive Shops
Automobile repair shops often make use of trailer air compressors to power different types of pneumatic tools. Examples are impact wrenches for loosening and tightening lug nuts, nail guns for quick framing, and spray guns for even painting and coating. In addition to powering tools, pneumatic air compressors for trailers are used to inflate tires.
HVAC Service
Trailer air compressors are used by HVAC servicemen to perform system tests - pressure tests and leak tests. Also, pneumatic tools powered by the compressor are used for cutting, fastening, and fitting. If an HVAC system needs servicing, the trailer air compressor can be connected to supply part of the system with compressed air to dehumidify it.
Road Repair and Paving
Road repair services call for the use of many pneumatic tools, from jackhammers to nail guns, all of which require compressed air to function. Trailer air compressors take care of this need easily. In addition, having the compressor on a trailer makes it very easy to transport to different locations where repairs are needed.
Pneumatic Regulations
Pneumatic wrenches and lifts are very common in tire-changing facilities. Trailer air compressors provide the needed air pressure for these tools to work. With a mobile air compressor on a trailer, changing tires becomes quicker and easier to do.
Film and Events Production
Whether indoors or outdoors, production companies require portable air compressors to power tools like handheld air monitors, airbrush guns, and paint sprayers. The mobility of trailer compressors makes them ideal for use in different locations, while the compressed air ensures a smooth and uninterrupted production process.
Buying an air compressor trailer is a challenging task, as customers have to think about many factors such as business needs, performance, safety, etc.
Understand business needs
People should clearly understand their business needs before purchasing a mobile air compressor. What type of projects will they use it for? What tools do they need to power? What levels of pressure and volume do they require? How often will they use it and for how long each time? Where will they use it - at what kind of job sites and how far from the nearest power source? What budget constraints do they have? Answering these questions can help determine the type and size of the air compressor that best fits business needs.
Pay attention to the performance
When choosing a mobile air compressor, pressure and capacity are two key performance metrics that users should consider. Pressure is measured in pounds per square inch (PSI) and indicates the force with which the compressed air is delivered. Higher pressure ratings mean the compressor can drive tools requiring more power. Users need to select a model with a maximum pressure that matches the tools they plan to use. Capacity, or airflow, is measured in cubic feet per minute (CFM). It shows the volume of compressed air produced. Projects need more CFM to run multiple high-demand tools simultaneously. Consider peak CFM output and the compressor's tank size, which affects how long it can provide air before refilling.
Choose the right fuel source
Air compressors are available in electric, gasoline, and diesel-powered models. Each type has advantages and best-use scenarios. Electric compressors are great for small portable projects where the worksite is near an electric outlet. Gas-powered compressors provide more flexibility and are suited for job sites far from power sources. Diesel compressors generally have larger capacities and tank sizes. Users should match the fuel type to typical working conditions and project needs. Considering factors like tool demands, worksite locations, and whether electricity will be readily available, users should choose the fuel source that ensures the compressor's proper functioning.
Consider safety features
When selecting a mobile air compressor, it's important to look for safety features that help protect users during operation. User manuals should explain proper usage, including guidelines for securing tools and avoiding over-inflating. Ropes, straps, and tie-downs can be used to prevent tools from shifting and ensure safety. Hand washing is essential after handling compressor hoses, which may contain substances harmful to health. Compressors should be grounded to prevent electrical shock hazards. Grounding helps avoid static electricity buildup. Grounding is especially important when refueling the compressor or while working in dry, sandy areas.
