Questions you may have
Allow me to respond to your question.
What countries and regions do your products export to?
What is the maintenance cycle of your products, and how to maintain them?
Core Maintenance Principles
For harsh working conditions (heavy dust, high temperature, 24-hour continuous operation), all maintenance intervals shall be shortened by 50%. Use only dedicated compressor oil (no mixing of different oil types); condensate must be drained regularly.
Maintenance Items
Air Filter / Oil Filter / Screw Compressor Oil
- First service: 500 operating hours / 3 months
- Routine service: Air filter – 1000-2000 operating hours / 6 months; Oil filter + Screw Compressor Oil – 4000 operating hours / 12 months
Oil Separator Cartridge:
4000-6000 operating hours / 12 months
Cooler / Drain Valve
- Cooler: Clean monthly, deep clean quarterly
- Drain Valve: Drain condensate daily
Pressure Gauge / Safety Valve:
- Calibrate every 6 months
How about your repair and after-sales services? Do you provide a quality guarantee?
We adhere to the tenet of “Sales are just the start, service has no end”. We will actively respond to all inquiries from customers and provide tailored solutions, and the main unit of our products comes with a 3-year warranty.
How to choose the product that suits you?
Choose reciprocating air compressors for low gas consumption and intermittent operation.
For high gas consumption and continuous operation (e.g., in factories or workshops), rotary screw air compressors are ideal. We offer multiple versions including portable, mobile, and stationary models.
Opt for scroll air compressors if low-noise performance is required.
Select centrifugal air compressors for ultra-high flow rates.
Choose variable frequency (VF) air compressors when operating conditions fluctuate significantly.
For outdoor applications without a fixed power supply, diesel-powered air compressors are the go-to option.
What is your delivery lead time and minimum order quantity (MOQ)?
You are our valued customer even with a single-unit order. While the exact delivery time is not fixed, we will arrange shipment for your order at the earliest possible time. Linyi City, the home of our manufacturing base, is known as the Logistics Capital of China—and this is why we are fully confident in our delivery efficiency.
How are your products packaged, and is the packaging sturdy?
All our products are fully assembled and rigorously tested before shipment. Only after passing the quality inspection will we arrange delivery in sturdy wooden crates, with shock and drop-resistant cushioning materials filled between the crates and products to ensure safe arrival at the customer’s premises.
