Product Q&A

Q:Why is Class 0 oil-free certification critical?

Oil contamination can ruin entire production batches and violate food safety regulations. Class 0 is the strictest standard, guaranteeing zero oil content in the delivered air.

Q:What is the exact output pressure range?

It is designed for medium high pressure, typically 20-40 bar (290-580 psig), which covers the standard requirements for PET stretch-blow moulding.

Q:Is maintenance expensive or frequent?

No. The oil-free reciprocating design uses self-lubricating, wear-resistant components that extend service life. Regular maintenance is straightforward and interval-based, reducing downtime.

Q:How does this compressor save energy?

The system includes intelligent load/unload controls and can be paired with variable frequency drives (VFD) to match air supply with actual demand, minimising energy waste during low-load periods.

Q:What after-sales support do you offer?

We provide full technical support, spare parts supply, on-site commissioning, and customised maintenance plans to ensure your production runs without interruption.
