The Key Decisions Behind Choosing the Right ELGi Air Compressor

Understanding Your Air Demand

Before selecting an air compressor, it is essential to know the amount of compressed air required for the operation. The air requirements vary with the machines, tools, and production processes and can vary with the number of systems running simultaneously. If a business is looking to buy a compressor, it will be better to actually see how much it is being used than to just take a wild guess.

Air demand should be considered for normal working conditions and at times of increased usage. This provides a better idea of the compressor's required performance.

Start by checking:

• ⚙️ Air-consuming equipment: Identify machines, tools, and processes that require compressed air.
• ⚙️ Flow requirement: Determine the quantity of compressed air that is required for each application during operation.
• ⚙️ Concurrent use: Take into account the possibility of multiple air-consuming devices being used concurrently.
• ⚙️ Peak demand: Take into consideration time periods during which air usage temporarily spikes.
• ⚙️ Future use: When selecting a system, take into account how it will be used in the future to ensure that it is not taken beyond its appropriate range.

Getting the Capacity Right

The actual capacity of the compressor should be determined according to the load and not by its size or motor rating. The capacity is adequate for the production required without continually straining or running the equipment too much above its design capacity. Under-capacity and over-capacity can both be a problem in the use of the system.

Capacity selection involves:

• ⚙️ Required air flow: Ensure that the total demand of all equipment that is connected to the compressor is matched.
• ⚙️ Operating conditions: Determine if the compressor will be used occasionally, regularly, or continuously.
• ⚙️ Peak load: Permit brief bursts of higher-than-normal air usage.
• ⚙️ Duty cycle: Be aware of how many times the compressor will load, unload, or run in a working day.
• ⚙️ Expansion margin: Allow for future growth requirements without building up too much "padding".

Choosing the Suitable Compressor Type

Not all compressors are created equal, and not all are suitable for all applications. The operating principles are different for various air demand, pressure, operating time, and working environment. Changing the type according to the actual application can make more of a difference than just picking a common type.

The use of the compressed air and the operating pattern the system will have should be taken into consideration. This assists in linking the gear selection to actual job requirements.

Choices of type can be based on:

• ⚙️ Application requirements: Determine if the compressor is for production equipment, tools, automation, or other applications.
• ⚙️ Hours of operation: Continuous use may be different from occasional use.
• ⚙️ Requirements for output: The choice of compressor technology should be determined by the airflow and pressure requirements.
• ⚙️ Installation environment: Space, temperature, dust, ventilation, and surrounding conditions may affect suitability.

Matching Pressure to the Application

Flow is not the only component that defines compressed air systems. These may vary from machine to machine and from process to process to get the machine to function properly. Too little pressure can have a negative impact on equipment performance; too much can result in higher energy consumption without added value.

When planning pressure, take into account:

• ⚙️ Equipment requirement: Determine the kind of pressure indicated by the tool and equipment connected.
• ⚙️ Minimum operating level: Make sure that during normal demands, the system has an adequate pressure.
• ⚙️ Distribution losses: Take into consideration pressure loss in the piping, filters, dryers, etc. during distribution.

Looking at Energy Consumption

With a compressor running for many hours, it is important that energy is being used correctly, as it plays a significant part in the overall cost of its operation. Compressor size, operating pressure, load profile, system efficiency, and management all have an impact on electricity consumption. Relying solely on the cost of the equipment can therefore fail to account for a substantial proportion of the cost of the equipment over its lifetime.

Energy considerations include:

• ⚙️ Power consumption: Discuss electrical power consumption under various operating conditions.
• ⚙️ Load pattern: Knowledge of the compressor operating time under load and when unloaded.
• ⚙️ Pressure setting: Do not set unnecessarily high pressures, as they maycause extraa energy consumption.
• ⚙️ Operating schedule: Consider how many hours per day and days per week the compressor will run.

Considering Available Installation Space

The compressor can be at the heart of the air system, but it must fit into the facility without causing any practical issues. Before installation, the space available, ceiling height, ventilation, access routes, and service clearance should be taken into account. If a machine is physically in place but can't be accessed effectively for maintenance, this can cause issues down the road.

Check the installation area for:

• ⚙️ Installation: Ensure that the compressor can be installed without interfering with other operations.
• ⚙️ Service clearance: Leave adequate space around the machine for inspection/ maintenance.
• ⚙️ Ventilation: Ensure suitable ventilation around equipment as per installation requirements.
• ⚙️ Access Route: Ensure that the compressor can be put in place and can be accessed if needed.

Checking Maintenance and Service Needs

To keep a compressor running as well as it was designed, it must be maintained. Depending on the equipment and operating conditions, other parts of the system such as filters, coolers, connections, and lubricants might need to be inspected or serviced. Before making a purchase, it's important to be aware of maintenance needs to ensure that businesses are prepared for the long-term responsibility of operating the system.

Planned maintenance can consist of:

• ⚙️ Regular inspections: Make routine inspections to find out if there are signs of wwear leaking, contamination or other problems.
• ⚙️ Filter Servicing: Filters should be serviced based on equipment's operating conditions and recommended maintenance schedule.
• ⚙️ Lubricant management: If applicable, proper lubricant and lubricant change intervals should be adhered to.
• ⚙️ Access for spare parts: Common components should be readily available for replacement when necessary.

Planning for Long-Term Performance

The selection of an air compressor must not be confined to the sole need for the immediate production. It can be used in the facility for a number of years, and there are several factors to consider before finalizing the purchase: reliability, operating conditions, maintenance, efficiency and future changes. A machine which works for today's job might not be able to meet the needs of tomorrow's task.

• ⚙️ Service life expected: Consider the equipment design to see how it works in the conditions it is used.
• ⚙️ Future expansion: Allow for possible increase in production or add air consuming equipment.
• ⚙️ Replacement planning: Be familiar with the maintenance and component replacement needs for the working life of the equipment.
