Compressor Equipment Functions
Aftercoolers
These are mechanical heat exchangers designed to remove the heat-of-compression from the compressed air flow and prep the air so it can enter a dryer.
Oil Coolers
This is a heat exchanger used to cool the lubricating oil flowing from the oil separator, which reduces the oil temperature for reuse.
Dryers
Dry, warm air that enters the compressor and contains higher moisture levels to prevent damage to the compressor.
Oil Filters & Complete Oil Filtration Systems
Are used to remove particulate from liquid oil in oil-lubricated air compressors.
Lubricators
Help compressors run more smoothly and quietly and protect them from overheating.
Bag Filters
Keep water, oil, and dirt from reaching pneumatic tools, improving the system’s health.
Filter Candles
Remove oil, dirt, odour, and water from the compressed air supply.
Air & Oil Separators
Function as filters by separating the oil from compressed air.
Air Inlet Filters
Stop contamination from atmospheric air, protecting against wear from dust.
Pressure Regulators
Help the machine start easier by relieving head and lien pressure.
Heat Recovery Equipment
Allows the recycling of excess heat.
Intercoolers
Their primary function is to cool air before it enters the next compression stage.
Non-Return Valves
Let air flow from one side to the other while blocking airflow in the opposite direction.
Pressure Relief Valves
Control and limit the pressure build-up in a system.
Pressure Safety Valves
Reduce excess pressure by releasing a fluid volume when a predetermined maximum is reached.
Blow Off Valves
Are used to prevent compressor surges.
Inline Valves
Used in air compressors provide a steady flow of compressed air for an extended period to meet the needs of various applications.
Receivers
Used to store high-pressure air. Their volume reduces pressure fluctuations arising from load changes and compressor switching.
Guide Vane Actuators
Are fixed grooves found in turbines that help direct water, gas, or air around bends at maximum efficiency.
Condensate Drains
Typically crafted with PVC pipe or metal, and they provide a funnel for the humidity and condensation
Gaskets
Mechanical seals which fill the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.
Instrumentation (Temperature & Vibration Probes)
Devices used to measure temperature using contact-style sensing methods. A vibration sensor is a device that measures the amount and frequency of vibration in a system, machine, or piece of equipment.
Cooling Tower Equipment
A specialised heat exchanger in which air and water are brought into direct contact to reduce the water’s temperature.
Frequently Asked Questions
An industrial air compressor is a mechanical device that generates pressure in compressible fluids or gases. It utilises either an electric motor or a diesel-powered engine to convert power to potential energy stored in pressurised air.
Air compressors work by forcing atmospheric air under pressure to create potential energy that can be stored in a tank for later use. Like an open balloon, the pressure builds up when the compressed air is deliberately released, converting the potential energy into usable kinetic energy.
There are two basic types of air compressors. Positive displacement and dynamic compressors.
- Positive displacement compressors work by drawing air into a compression chamber through an intake valve and mechanically reducing the volume of the chamber through a motion until a set pressure is reached. These include rotary screw compressors and reciprocating compressors.
- Dynamic compressors are rotary continuous-flow machines in which the rapidly rotating element accelerates the air as it passes through the element, converting the velocity head into pressure, partially in the rotating element and partially in stationary diffusers or blades. These include axial compressors and centrifugal compressors.
We specialise in conducting major & minor overhauls on all types of compressors, including:
- Centrifugal Compressors – which slow and cool incoming air through a diffuser to build up potential energy.
- Rotary Screw Compressors generate energy via two internal rotors that turn in opposite directions.
- Reciprocating Air Compressors – which work via a piston inside a cylinder, which compresses and displaces the air to build pressure. They are available in single or multi-stage variations, which determines the pressure ranges they can achieve.
- Axial Compressors – which have a high-efficiency rate making them best suited for applications requiring high horsepower.
- One thing to consider when selecting an industrial air compressor is energy efficiency. Think of the required airflow and pressure to determine what size compressor you need. The output of an air compressor is measured in cubic feet per minute (CFM). The higher the CFM of a compressor, the more applications you can power with it.
- Consider the frequency of servicing needed for the compressor to ensure long equipment running life. Features to look at when deciding which compressor is the right for you include horsepower, voltage, and CFM.
