Contimac compressor buying guide
When purchasing a compressor, it is important to consider a few factors to ensure you choose the best option for your needs.
- What pneumatic devices do you plan to connect to the compressor, and will you use them simultaneously?
- How much will the compressor be used? Continuous or intermittent?
- Do you want a stationary compressor or a portable one?
- What type of electrical network will the compressor be used with? 1-230V or 3-400V?
- Do you want an open or soundproofed compressor setup?
Calculating compressed air requirements
Add together the air consumption of all the pneumatic devices you want to use simultaneously (values can be found in the manufacturer's documentation).
Estimate the duty cycle of each device. For example, a spray gun consuming 180 l/min that you use 40% of the time: 180 l/min x 0.4 = 72 l/min. This is the device's compressed air requirement per unit of time.
Estimate the simultaneous usage factor. Not all pneumatic devices are used 100% of the time simultaneously.
Estimated compressed air requirement:
Total (device air consumption l/min x duty cycle x number of devices) x estimated simultaneous usage factor.
The more compressed air you use in a short period, the larger tank you should choose. A large tank acts as a buffer and reduces the number of compressor start-ups. Note that piston compressors are limited to a maximum of 10 starts per hour to ensure a long motor lifespan. If the number of starts exceeds this, choose either a larger tank or a more powerful compressor.
Piston compressor or screw compressor?
Advantages of a piston compressor:
- Variable air demand: Suitable for fluctuating compressed air needs and capable of handling temporary peak demands.
- Intermittent use: Shuts off when the tank is full and does not need to run idle.
- Smaller air volumes: A cost-effective choice for lower compressed air requirements.
Advantages of a screw compressor:
- Continuous use (100% duty cycle): Suitable for constant compressed air demand.
- Larger air volumes: The most economical choice for higher compressed air demands.
- Screw compressors operate most efficiently within a pressure range of 5–13 bar.
- Low vibration and quiet operation.
- User-friendly interface that displays key compressed air parameters and maintenance alerts.
