A Competitive Price Guide To Air Compressors In Singapore 2023
15 May 2023
Getting the best deal on an air compressor may seem complicated and overwhelming for a first-time purchase, but knowing the specifications needed for the task you have in mind will simplify and narrow down your options. Understandably, it’s not just about the air compressor’s tank size for your desired air pressure, you must also determine the power source you have available. Moreover, take into account the setting as well as how long you need the unit running. Ask yourself if you intend the air compressor for home use or on an industrial scale and whether you’ll be operating it indoors or outdoors on an intermittent or continuous cycle. To help you make an informed decision, we’ve provided a comprehensive buying guide along with a competitive price list for air compressors in Singapore.
2) Match the tank size with the airflow (SCFM) and air pressure (PSI) you need to achieve.
Larger air tanks have a better chance of producing consistent SCFM and PSI for a longer period of time since they would be depleted less often in comparison to smaller air tanks. As a rule, the minimum tank size should be six (6) times your tool’s required SCFM.
3) Identify your power source so you can properly determine if an electric or gas air compressor would be most applicable for the space and job you have.
4) Choose between an oil or oil-free air compressor.
5) Decide between a belt-drive or direct-drive air compressor.
How to choose the right air compressor1) Find out the air pressure you need to get the job done and make sure the air compressor is compatible with your pneumatic tool. To do that, you must familiarize yourself with the specifications indicated in these machines.
|Standard Cubic Feet per Minute (SCFM)||The average air consumption of an air/pneumatic tool or the rate at which air flows in and out of a compressor tank. Different tools require a specific SCFM to function optimally.|
|Pound per Square Inch (PSI)||The measure of how dense air is inside the compressor tank. Make sure that the PSI is enough to support all the pneumatic tools you intend to use. The recommended PSI range is 60 to 130 depending on the tool being used.|
|Horsepower (HP)||The power needed for the air compressor’s motor to operate. The size of the air compressor generally corresponds to the motor’s size.|
|Electric-powered Air Compressors||Gas-powered Air Compressors|
|Power Source||Electricity from a 120-volt outlet||Fuel like gasoline or oil|
|Recommended Use||Home or indoor use||Heavy-duty and industrial tasks|
|Portability||More portable due to smaller size and weight||Heavier and harder to transport|
|Noise||Quieter than gas-powered compressors||Motor tends to be loud, but less disruptive in outdoor settings|
|Maintenance||Simple to use and maintain||May require more frequent maintenance|
|Air Quality||Better air quality as they do not emit fumes||May emit fumes that can be a health hazard in confined spaces with limited ventilation|
|Oil-lubricated air compressors||Oil-free air compressors|
|Lubrication||Use oil as a lubricant||Pre-lubricated in a material like Teflon|
|Maintenance of Parts||Need periodic oil changes to prevent irreversible damage to motor and parts||Require less maintenance due to fewer parts|
|Application||Better suited for industrial use with longer lifespan and more heavy-duty||More compact and provide higher air purity, suitable for home use or clinical settings|
|Noise||Usually more quiet as they are consistently lubricated||Can be louder with a range of 60-80 dBA or above|
|Weight||Heavier due to more parts and lubrication system||Lighter and more portable due to fewer parts|
|Air Quality||Higher risk of contamination||Preferred by spray painters and in clinical settings due to higher air purity|
|Belt-drive air compressors||Direct-drive air compressors|
Price guide for air compressors in SingaporeThe price of an air compressor will mainly depend on its type, brand, power source, size, specifications, and features such as its capacity to run quietly or absorb shock. Below are the most common types of air compressors for sale and their usual price range in Singapore.
|Air Compressor Type||Price (S$)||Motor (HP)||Air Pressure (PSI)||Tank Size (L)|
|Belt-driven piston air compressors||800 – 1,900||2 – 3||115 / 8 BAR||30 – 100|
|Oil-free air compressors||170 – 4,000||1.5 – 5||115 – 130||9 – 230|
|Oil-lubricated air compressors||500 – 9,950||2.5 – 15||130||24 – 250|
|Direct-drive rotary screw air compressors||700 – 6,000||2 – 4||115 – 145||24 – 150|
|Electric screw air compressors||8,000 – 17,000||10 – 50||145||Not Included|
