Portable air compressors play an important role in many industries due to their lightweight, flexible and easy-to-move advantages. In the face of a wide range of products on the market, how to select the most suitable equipment for your industry needs? This guide will provide you with a detailed answer.
First, clear gas demand
(A) Pressure is the key
Different industries have different compressed air pressure requirements. In the automotive repair industry, tire inflation usually requires 0.2 - 0.3MPa pressure, while the paint job requires 0.4 - 0.6MPa; construction and decoration industry using air nail gun, the pressure is generally maintained at 0.4 - 0.8MPa. Therefore, before purchasing, be sure to understand the industry specific air equipment pressure requirements, to ensure that the rated exhaust pressure of portable air compressors to meet or even slightly higher than the actual demand. The rated exhaust pressure of the
Portable Air Compressor should be able to meet or even slightly higher than the actual demand, so as to ensure the stable operation of the equipment. For example, if you are engaged in automobile maintenance and often need to spray paint, then a portable air compressor with a rated exhaust pressure of about 0.6MPa will better meet your needs. (B) Accurate Measurement of Flow Rate Requirements
Flow rate determines the amount of compressed air output per unit time. You can estimate the total flow demand by counting the number of air tools used at the same time and their respective air consumption. For example, in a small carpentry workshop, if you use a nail gun and a small air pump at the same time, and the air consumption of the nail gun is 0.1m³/min and the air consumption of the air pump is 0.2m³/min, then the total flow demand is at least 0.3m³/min. Considering the peak demand that may occur in real life, it is recommended that you add 10% - 20% more to the flow demand to cope with unforeseen situations. For example, if more air tools are occasionally used in a woodworking workshop at the same time, this margin will ensure that the air compressor can still supply a steady flow of air.
Consider the characteristics of the equipment
(a) Select the right type of compressor
The common types of portable air compressors are piston, screw and scroll. Piston type has simple structure and low cost, which is suitable for the scenarios with low pressure requirement and intermittent use, such as home DIY and small repair stores. For example, if a home user occasionally uses an air compressor to inflate bicycle tires or inflate inflatable toys, a piston air compressor will be able to fully meet the demand. Screw type is smooth running, low noise, large exhaust volume, suitable for industries that need continuous air supply and have high requirements for air volume, such as some of the auxiliary parts of industrial production. In some small factories, if you need to continuously provide compressed air for production equipment,
Screw Air Compressor is a better choice. Scroll type is known for its low noise and high stability, and performs well in environments with strict noise restrictions, such as small operations around hospitals and schools. For example, when performing small pipe repairs near a hospital, the low noise generated by a scroll air compressor will not disturb the normal order of the hospital.
(ii) Focus on mobility
Portable air compressors have the advantage of being easy to move, so you need to focus on their size, weight, and mobile design. In the construction site and other need to frequently change the operating location and the terrain of the complex environment, equipped with tires and small size, light weight equipment is more convenient to move. Like some small portable air compressors, the size of a small suitcase, weighing only a dozen kilograms, equipped with wear-resistant tires, in the construction site of the rugged road can also be easily moved. For work in relatively flat but limited space, such as small workshops, designs with wheels and flexible steering are more practical. Additionally, the ergonomics of the handles on the equipment can also affect ease and comfort of movement. Some air compressors have handles that are wrapped in soft materials and shaped to fit the hand's grip, so that you won't feel uncomfortable when moving the equipment for long periods of time.
Third, pay attention to environmental factors
(a) noise restrictions can not be ignored
In some noise-sensitive industries, such as medical care, precision electronics manufacturing, indoor decoration, etc., the noise problem can not be ignored. Portable air compressor operation noise may interfere with the normal working order, and even product quality. Therefore, it is necessary to choose the product with lower noise, generally refer to the noise parameters of the equipment, such as some of the products can be controlled at 60 - 70 decibels, similar to the volume of a normal conversation, which can better meet the needs of such environments. At the same time, if the equipment has a sound insulation design, such as the use of soundproof enclosure, can also further reduce the spread of noise. For example, when servicing small equipment in a medical facility, choosing a portable air compressor with a low noise level and a soundproof enclosure can ensure that the maintenance work is carried out without disrupting medical activities.
(ii) Adaptation to harsh environments
For industries operating in outdoor, mining, construction sites and other high-dust, high-temperature or low-temperature environments, it is important to select a portable air compressor with good environmental adaptability. In high dust environments, the equipment should have a highly efficient air filtration system to prevent dust from entering the inside of the compressor, resulting in wear and tear of components. Some air compressors are equipped with multi-layer high-efficiency filtration devices, which can effectively intercept dust and extend the service life of the equipment. In a high temperature environment, it is necessary to ensure that the equipment has good heat dissipation performance to avoid overheating and affecting the stability of operation. For example, some of the air compressors use large cooling fins and efficient cooling fans, which can quickly dissipate heat. In low-temperature environments, it is necessary to pay attention to the starting performance of the equipment and the special requirements of the lubricant to ensure that it can start and work normally in low temperatures. Some air compressors adopt special lubricant and preheating device for low temperature environment, so that they can start smoothly even in cold winter.
Fourth, weigh the cost-effectiveness
(a) Reasonable control of procurement costs
Portable air compressors of different brands, models and specifications vary greatly in price. Under the premise of meeting the demand for air and equipment characteristics, you can compare the prices of several products. However, it should be noted that you can't only take the low price as the only selection criteria, too low price may mean that the quality and performance of the equipment has hidden problems. For example, some low-priced products may be in the selection of materials, manufacturing process is lacking, resulting in shorter service life, failure rate increases. Therefore, it is necessary to comprehensively consider the quality, performance and price of the product, and choose the more cost-effective products. For example, some well-known brands of portable air compressors, although the price is relatively high, but the use of high-quality materials and advanced manufacturing processes, equipment performance is stable, long service life, in the long term, more cost-effective.
(ii) Reduce operation and maintenance costs
The operation cost mainly involves energy consumption. You can pay attention to the energy efficiency labeling of the equipment and choose products with lower energy consumption. For example, some portable air compressors with energy-saving technology can significantly reduce electricity expenses in long-term use. For maintenance cost, understand the replacement frequency and cost of the equipment's wearing parts, as well as the convenience and cost of after-sales service. Choosing brands and products with strong versatility of wearing parts and perfect after-sales service network can reduce the difficulty and cost of maintenance and guarantee the uptime of the equipment. Some brands of air compressors, its wearing parts in the market is easy to buy, and the price is reasonable, at the same time the brand has many after-sales service outlets across the country, can provide timely maintenance services for users, greatly reducing the user's maintenance costs and equipment downtime.
Through the comprehensive consideration of air demand, equipment characteristics, environmental factors and cost-effectiveness, you will be able to accurately select the most suitable portable air compressor for your industry, providing efficient and reliable air source support for production operations, and assisting the development of the industry.
