Here, we are going to mention the 10 most imperative things you should know when buying a reciprocating air compressor.
Compressor type
Commonly, three types (single-stage compressors, two-stage compressors, and twin compressors) of reciprocating compressors are in the market. Single-stage units compress the air in one stroke, from ambient to end pressure. They typically go up to 20 CFM at a pressure of 125 psi. For more power, you should go for a two-stage compressor. A two-stage compressor uses two stages to compress the air to the end pressure. Two-stage air compressors go up to about 81 CFM capacity (Free Air Delivery) at about 175 psi. Depending on the amount of capacity and pressure you need, you can choose either a single-stage compressor or a two-stage compressor.
Capacity and pressure
The capacity (CFM) and the pressure of the air compressor are the two most imperative specifications of an air compressor. To figure out the capacity that you need, just add up the air consumption of all the air tools that you will use. You should check again the specifications of the air tools to find out the pressure that you need. It would be a prudent decision to purchase a compressor that can deliver more than you need. Because in future, you may need to add more tools.
Horsepower
Don&#;t concentrate on horsepower because this is the result of the required pressure and capacity that you need. So, always look at capacity (CFM) and pressure (psi).
Electrical connections
Don&#;t purchase an air compressor without knowing the voltage at your utility. Do you have single phase or 3 phase powers? Because installing extra electrical wiring can be more expensive than the air compressor itself.
Noise
Since a reciprocating compressor produces a lot of noise, thus, always check the noise level before purchasing one. Don&#;t forget to add enough ventilation holes at your facility. Moreover, a reciprocating air compressor generates a lot of heat, so adequate cooling is required.
Tank size
Most reciprocating compressors come with a 100 to 500 litre tank. A larger tank size is always a good choice. A bigger tank means that there is a bigger compressed air buffer.
A bigger compressed air buffer is beneficial when you need to use big tools that grasp more air than the capacity of your compressor.
Compressed air filter
How are you planning to clean your compressed air?
Compressed air is hot, wet and dirty. Based on your application, you need to filter it and eliminate water and oil. There are filters available to abolish water (droplets), oil, and dust. For even dryer compressed air, you need to get a compressed air dryer.
Other options
There are other options that you should think about.
· Pressure regulators to regulate the tank pressure back to a stable
· Size and number of air connections
· Vertical or horizontal tank
· Manual or automatic drains

Weight
Your new air compressor comes on a wooden pallet. Depending on your need, you can keep the pallet or remove it. Always think about how you are going to plan your air compressor before buying it.
Duty cycles
The duty cycle refers to the percentage of time your compressor can run.
Most single-stage compressors have a duty cycle of only 50%. So, when you run your compressor for 5 minutes, it needs 5 minutes to cool down. If a compressor has a 100% duty cycle, it can run 24 hours. So, always purchase a compressor that has a 100% duty cycle.
These are 10 things that you should consider before buying a reciprocating air compressor for your utility.

Air compressors being versatile machinery, can be a great addition to any business. These robust and reliable devices perform a variety of tasks compared to electric power tools. They serve multiple purposes, from powering small appliances to substantial industrial applications. Air compressors act as crucial in running both industrial and commercial businesses. However, choosing the best air compressor suppliers for your business needs can be arduous. There are a few factors to consider before choosing the air compressor for your business needs. These aspects include the type of application, work environment and the duration of use, to name a few. How do you find the right one for your business with so many to choose from, portable or stationary, piston or rotary screw compressors?
Looking at each of the following factors will help you find the best air compressor for your business, no matter the size or need.
Air compressors come in various grades based on their capacity and applications. Check with the best air compressor suppliers in Kolkata for these grades before making any purchase decisions.
These compressors are small and portable and often used for the house or a small garage workshop for inflating tires. Because they are powered by pistons, can handle low pressures, and do not offer a continuous flow of compressed air and are easily prone to overheating.
Industrial air compressors are the perfect choice for constant use. They have a robust and more durable design to run at a constant temperature, regardless of demand. As a result, compressors in this category are used for efficient long-term use in industries, right from factory shop floors to ships and oil rigs.
Higher the HP values of the compressor, the better the PSI. The value of CFM is based on the PSI. The higher the CFM of a compressor, the more applications we can power with it. Choosing a compressor with a CFM of about 20% to 30% over the needs is recommended to cover future business expansion.
The duty cycle indicates the number of minutes the compressor is allowed to function for every 10 minutes. The duty cycle of industrial compressors is usually 75% to 100%, i.e. they can work continuously.
Air compressors are either powered by electricity or gas. Electric air compressors are very common and can be used with a regular electricity supply, with ventilation as a consideration. On the other hand, petrol and diesel air compressors are movable and work outdoors in adverse weather conditions. Hence, their robust nature and lower maintenance and fuel cost to compensate for the higher initial cost.
Stationary compressors are industrial grade, usually large, designed for proper installations. Their higher horsepower and much storage capacity make them excellent choices for uninterrupted usage. On the other hand, portable air compressors are small and light. These are best for the contractors because it makes them easy to move around work areas.
Fixed speed controls aim to keep the speed of the compressor constant. Variable speed controls allow adjusting the speed of the compressor so that its output equals the demand.
The air dryer removes water vapor and other particles from the compressed air. As a result, drying the compressed air avoids contamination, corrosion, and control malfunctions.

Shell life of the product is more important than saving initial buying cost. For example, choosing a high-quality air compressor may be expensive; in return, it will save replacement and repairs costs.
While there are many manufacturers in the field, your air compressor needs to be reliable throughout its service life, and it requires good support to keep it functioning optimally. Therefore, choosing and buying from an experienced and professional manufacturer or supplier with after-sale service is essential to ensure a long life run of the equipment.
It&#;s always advisable to consult the authorized top air compressor suppliers while making a purchase for your business.
