FAQs

Q1: Why is my rotary screw air compressor giving a "High Temperature" alarm and shutting down?

A: This common issue is usually driven by low or degraded synthetic compressor oil, a blocked radiator (air/oil cooler), or a clogged screw compressor oil separator. Regular maintenance is key to avoiding these thermal shutdowns, and our team is always ready to assist if you need a professional check-up.

Q2: What should I do if my industrial air compressor is running but building no pressure?

A: When a compressor runs but fails to build air pressure, the root cause is often a faulty inlet valve (unloader valve) that is stuck closed, a failed solenoid valve, or an air leak within the pipeline network. If you need help troubleshooting the exact cause, feel free to reach out to our technical support.

Q3: Why is there oil coming out with the compressed air into my production lines?

A: Finding oil in your compressed air lines typically indicates that your screw compressor oil separator filter is worn out or saturated and requires replacement. It can also happen if the oil tank is overfilled. We can easily provide you with the correct replacement filters upon contacting us.

Q4: How often should an industrial screw air compressor undergo preventive maintenance?

A: Standard preventive maintenance is generally recommended every 2,000 to 4,000 operating hours (or every 6 months) to change the compressor oil, swap filters, and inspect system efficiency. If you'd like to schedule routine servicing for your facility, our team is available to help.

Q5: Is it better to buy a brand-new air end or refurbish the old screw block?

A: Refurbishing your compressor air end (screw block overhaul) is highly cost-effective and restores factory operational efficiency without the heavy investment of buying new equipment. At Green Star, we provide dependable air end rebuilding services, and you can contact us anytime to evaluate your machine's condition.

Vacuum Pumps Engineering & Maintenance

Q6: Why is my industrial vacuum pump smoking and losing its suction power?

A: A drop in vacuum suction or visible smoke usually means the vacuum pump oil is contaminated or the internal exhaust filter is completely clogged. Performing an oil change and replacing the exhaust filter elements will fully restore efficiency. Feel free to contact our sales department for the right parts.

Q7: What components are included in a professional vacuum pump service kit?

A: A standard vacuum pump service kit contains essential wear-and-tear parts like high-grade vacuum vanes (carbon or composite), exhaust oil mist separators, shaft seals, and gaskets to prevent vacuum leaks. We supply these kits for various brands and models upon request.

Compressed Air Networks & Pneumatics

Q8: How can a manufacturing plant eliminate energy waste and pressure drops in its piping?

A: Energy loss can be minimized through a proper compressed air network design, using smooth air pipelines with optimized diameters, and ensuring the efficiency of your air dryers and pressure regulators. Our engineers are happy to discuss optimizing your system whenever you need support.

Q9: What specific pneumatic components and accessories does Green Star supply in KSA?

A: We supply a comprehensive inventory of industrial pneumatic components, including air cylinders (pneumatic pistons), high-frequency solenoid valves, filter-regulator-lubricator (FRL) units, and air storage tanks. Let us know your requirements, and we will help you find the right component.
