What Is A Diesel Rotary Screw Air Compressor?
A diesel rotary screw air compressor is an air compressor fueled by diesel that uses rotors to compress air. Diesel air compressors allow operators to generate compressed air on demand for powering tools and equipment.
How Does A Diesel Rotary Screw Air Compressor Work?
A diesel air compressor uses a small engine to convert diesel fuel into mechanical power and then converts that mechanical power into air power.
Like all diesel engines, the diesel engines found in rotary screw air compressors are internal combustion engines. They combine air, fuel, and lubrication in high-pressure cylinders, forcing the mixture to combust, which moves the engine&#;s pistons.
This mechanical movement forces the rotors (AKA rotary screws) to move, which compresses the air. This air is circulated through the system, along with lubricating oil, passing through various filters and coolers, before it is ready for use.

What Are The Benefits Of Diesel Air Compressors?
There are numerous benefits to diesel air compressors, including:
Same Fuel Type: Operators who already have a diesel truck will save time at the pump if they match their fuel type. Some diesel air compressors, such as VMAC&#;s D60, can even be plumbed right into the vehicle&#;s fuel tank, making fill-ups a breeze.
Fuel Efficiency: While diesel and gasoline costs are often similar per gallon, diesel is approximately 25% more efficient to burn. That means the same amount of fuel goes a lot farther between fill-ups. A diesel rotary screw air compressor can be a smart choice for operators concerned with fuel costs.
Easy To Move: Diesel rotary screw air compressors are mounted on the truck&#;s deck, making them easy to move between trucks if operators upgrade their vehicle. Alternatively, operators can use a skid-mounted or wheel-mounted diesel air compressor, which easily moves around a job site.
High Flashpoint: The high flashpoint of diesel makes it a safer option than gasoline in environments where sparks frequently occur.
Reliable Engines: Diesel engines have a reputation for being hardy, and small diesel engines, like those used in rotary screw air compressors, are no exception. Operators who want an air compressor backed by a reliable small engine may favor diesel rotary screw air compressors.
What Are The Benefits of Rotary Screw Air Compressors?
Rotary screw isn&#;t the only type of diesel air compressor available, but it is the superior option for mobile applications. When compared to reciprocating air compressors, there are numerous benefits:
100% Duty Cycle: Rotary screw air compressors run at 100% duty cycle, while most reciprocating air compressors can only run at 20 to 30% duty cycle. That means for every 100 seconds a recip air compressor runs, it&#;s only supplying full power for 20 to 30 seconds. Some 2-stage reciprocating air compressors can run at 100% duty cycle, but even these will eventually run out of air in the tank because they produce less power than the tools use. Because of these shortcomings, operators with reciprocating air compressors need to purchase bulky air receiver tanks to store extra compressed air and pick up the slack.
Longer Lifespan: Rotary screw air compressors are built to last. In a mobile setting, manufacturers like VMAC guarantee the rotary screw will outlast the life of your truck (with proper servicing). Meanwhile, reciprocating air compressors are known to break down and require more routine replacement.
More CFM: Rotary screw air compressors are also powerful, providing more CFM per HP than reciprocating air compressors; this means a smaller air compressor can provide higher outputs, saving weight and space on vehicles. Quieter: Reciprocating air compressors tend to be loud, especially compared to most rotary screw air compressors.
Energy Efficient: Rotary screw air compressors are more energy efficient. Operators can save on fuel and trips to the gas station by choosing a rotary screw model.
With so many benefits, why would anyone choose a reciprocating air compressor? First, they have a lower upfront cost, so they require a smaller capital investment. A reciprocating air compressor can be a logical short-term choice for budget-strapped buyers.
The second reason people choose reciprocating air compressors is that they can do many of the repairs themselves. Rotary screw air compressors are more complex machines and require qualified service technicians if they break. However, a rotary screw air compressor that is properly maintained should not require skilled service repair work.
Tools Frequently Powered By Diesel Air Compressors
Numerous applications use diesel air compressors to power their air tools. The most common air tools powered by diesel air compressors include:
- Jackhammers
- Impact wrenches
- Tire inflation tools
- Grinders
- Sanders
- Chipping hammers
- Backfill tampers
When Should I Consider A Diesel Rotary Screw Air Compressor?
Operators who already have diesel trucks or equipment should consider diesel rotary screw air compressors. Vehicle-mounted options are a great fit for mobile heavy-duty mechanics, mobile tire service technicians, and 24/7 roadside repair technicians. Meanwhile, skid-mounted or wheel-mounted diesel air compressors are a solid option for remote job sites
Additional Diesel Air Compressor Resources
1. What is Diesel Air Compressor?
Generally, there&#;re two main air compressor categories: positive displacement and dynamic.
Comair are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
Under these two umbrella categories, there can be many types of air compressors based on the working theory, the main structure, or even the types of motor or engine of the air compressor.
The positive displacement air compressor is the most commonly used compressor and it can be driven either by diesel engine or electric motors. Nowadays more and more leading air compressors manufacturers take the diesel air compressor as one of their main products.
The Diesel Driven Air Compressor is a complex system with numerous components. However, in summary, there&#;re two core components: Air End and Diesel Engine. Surely the air end is the heart of the air compressor for it&#;s the part that draws air from the atmosphere, forces it into a much smaller space, and compresses it. But this air needs a power source to operate, which is where the diesel engine comes in: the diesel engine converts diesel fuel into motion, forcing the air end to move and the system to compress air.
2. Types of Diesel Air Compressor
Nowadays there&#;s a great variety of diesel air compressors made by various manufacturers of standard & custom diesel compressors. Generally, there are two main types of Diesel Air Compressor:
Diesel Portable Air Compressor: It&#;s equipped with a lifting ring for safe and convenient lifting and transportation. Thanks to this design, this diesel engine air compressor is easy to move and even can move flexibly in bad terrain conditions.
Diesel Stationary Air Compressor: Compared with Diesel Portable Air Compressor, the Diesel Stationary Air Compressor is larger in volume and occupies more space. This kind of air compressor shows more stability.
3. Applications of Diesel Air Compressor
All the air compressors are mainly used as power equipment in which the pressurized air is created as potential energy. Compared with other energy-generating equipment, the air compressor is quieter, lighter, and with less chance of a breakdown.
In particular, the Diesel Portable Air Compressor, which is powered by a diesel engine, can be used in any location or environment: it&#;s commonly used on construction sites, in manufacturing plants, and even for handheld screwdrivers as an energy source.
4. How to Choose Diesel Air Compressor?
As we mentioned at the beginning, the air compressors can be classified into three categories according to the type of motor inside: the electric air compressor is a very common and quiet type, but it&#;s less powerful compared with fossil-fuel driven compressors; the petrol engine air compressor might be lighter, quieter and less expansive type, but it may not output similar torque as a diesel air compressor does; the diesel air compressor is noisier compared with other two types, but it&#;s movable and more powerful.
Among so many diesel portable air compressor manufacturers & suppliers, how to choose the most reliable manufacturer of standard & custom diesel compressors? The tips are the following:
PSI Rating: The PSI is is a common unit of pressure used in many different pressure measuring applications. The higher the rating, the more air the tank has. In different applications the requirements for the pressure are different. Thus, the PSI Rating is an important reference parameter of the industrial portable air compressor.
The experience and reputation of the manufacturer: It&#;s critical to choose an established and reputable Diesel Portable Air Compressor manufacturer. With years of experience, they will offer you the right product based on your needs, budget, and application.
