Introduction
Polyethylene terephthalate (PET) is a type of plastic used across several industries, such as food and beverage, personal care, and household. Since it is such a strong material, facilities that produce PET packaging or bottles need compressed air delivered at the appropriate pressure and flow. If the compressor does not match production requirements, facilities may be left to deal with subpar output, unnecessary usage of energy, and production interruptions.
If your facility handles PET packaging production, partnering with a trusted high-pressure PET air compressor supplier in the Philippines can help you select the proper equipment to ensure a quality product. This guide will help you determine which factors you should consider when selecting a PET compressor, and how Compresstech Resources can assist you in choosing one.
What Are High-Pressure PET Air Compressors?
High-pressure PET air compressors are engineered to deliver the amount of pressure required in PET bottle and container manufacturing, which is typically as high as 360-580 pounds per square inch (PSI). This is ideal for the stretch blow molding process, wherein the preform plastic is heated and expanded to create the desired bottle shape. The exact requirement, however, depends on the bottle design, production equipment, and material used.
Things to Consider When Choosing a High-Pressure PET Air Compressor
Selecting a PET bottle compressor requires a clear understanding of both your immediate needs and ongoing operating conditions. The following factors will help you determine the compressed air system that can support your production.
Required Pressure and Flow
Pressure and flow are two of the most important specifications you should take a closer look at when choosing a PET compressor. Selecting a compressor with insufficient pressure may affect production speed, while excessive pressure may result in energy waste and damaged products. The ideal pressure is 360-580 psi, but it is recommended that you consult a high-pressure PET air compressor supplier in the Philippines for a more accurate assessment.
Flow capacity is also important. A compressor must be able to supply the volume of air required by the production line, including periods of peak demand. Most facilities use compressors that can deliver about 28-53 cubic feet per minute (CFM), but it is also important to consider the number of blow molding machines, operating cycles, production rates, and other equipment using compressed air to determine the right airflow you need.
You should also account for potential fluctuations in demand instead of just sizing the compressor system around your average consumption.
Compressor Size
Physical compressor size and capacity should both be considered when selecting a PET compressor. Your unit must fit within the available space in your facility while also providing the required pressure and flow. You should also evaluate installation requirements, ventilation, access for servicing, and clearance around the equipment.
The compressor’s size can likewise create operational challenges, such as excess energy consumption and a surplus of output beyond your actual production requirements.
Oil-Free vs. Oil-Injected
Since PET bottle manufacturing follows strict quality standards, such as the ISO 9001:2015, compressed air quality is another important consideration. Oil-free compressors are designed to produce compressed air without the use of oil, a potential contaminant, in any component.
Oil-injected compressors, on the other hand, use lubricant within the compression process to seal, cool, and lubricate the components. They are suitable for many applications, but may not be appropriate for PET manufacturing.
Energy Consumption
Compressed air systems eat up a significant portion of the energy used in industrial processes. For this reason, energy consumption should be considered when selecting a PET compressor. A high-pressure PET air compressor supplier in the Philippines can help you evaluate a compressor’s rated power and how efficiently it operates under your actual conditions. They can also assess how these specifications can relate to your production cycle and system demands.
Compressor Technology
Different compressor technologies provide different pressure capabilities, characteristics, and maintenance requirements. There are several types of high-pressure air compressors that can be used for PET manufacturing, including:
- Multi-stage Reciprocating Compressors – The industry standard when it comes to direct high-pressure air blowing.
- Rotary Screw Compressors – Can be paired with boosters to blow high-pressure air with low vibration.
- Oil-Free Air Compressors – Provide clean air at high pressures to avoid contamination and ensure product safety.
Note that the right compressor technology should correspond to your production process, not just the maximum pressure rating.
Supplier Reliability
Your supplier’s capabilities matter just as much as the compressor itself. First off, they should be able to understand your production needs, review your technical requirements, recommend the right equipment, and give you support throughout the compressor’s service life. A reliable high-pressure PET air compressor supplier in the Philippines should also have extensive experience in industrial compressed air systems, access to a wide range of compressor technologies, and be able to respond quickly to your concerns or inquiries.
Maintenance Needs
Maintenance is a key requirement in ensuring that your production lines keep running during operations. High-pressure PET bottle compressors, specifically, may require specialized servicing when used continuously. Therefore, you should also consider how often your compressor needs inspection and servicing, or if replacement parts and technical support are readily available when you need them.
Discussing maintenance requirements with your supplier before procuring and installing will help you establish realistic servicing plans and give you more confidence in the equipment.
