Other Bulk Powder Vehicles: Suitable for cement, starch, and other industrial powder transport, where reliable, contamination-free compressed air is critical.

Key Product Advantages

✅ High-Efficiency Powder Handling: With a 12.5 m³/min large displacement, it delivers steady, powerful airflow to fluidize fine powders, preventing clogging and ensuring fast, complete unloading.

✅ Long Continuous Operation: Supports up to 120 minutes of non-stop use, meeting the demands of long-haul transport and bulk discharge without overheating or performance drops.

✅ Oil-Free, Contamination-Free Design: Eliminates oil carryover, ensuring clean, dry air that preserves the purity of food-grade materials like flour and prevents caking in lime or fly ash.

✅ Durable & Low-Maintenance Build: Heavy-duty construction and precision engineering reduce wear and tear, minimizing downtime and extending service life for fleet operations.

✅ Flexible Drive Compatibility: Matches standard truck PTO units with >500 Nm torque, making it easy to integrate into new or existing powder transport vehicles.

Q: What is the service life of your products?

A: 1 year After-sales service

Q: What is an oil free oscillating air compressor, and what is the difference from oil lubricated and piston types?

A: Oil-free oscillating air compressor adopts a unique oscillating movement structure, with 100% oil-free compression chamber and no lubricating oil involved in the gas compression process, ensuring the output air is completely oil-free, pollution-free, and meets high-purity gas requirements. Compared with oil-lubricated compressors, it avoids oil mist pollution, secondary filtration costs, and oil replacement maintenance; compared with ordinary piston compressors, it runs more smoothly, has lower

Q: Does the oil-free design affect the service life of the compressor?

A: No. Our oil-free oscillating models use self-lubricating high-performance materials for key moving parts, matched with precision machining and reasonable clearance design, which ensures low friction during operation without lubricating oil. Under normal use and regular maintenance, the service life of the core host can reach 8-10 years, which is equivalent to or even longer than that of ordinary oil-lubricated compressors, and there is no risk of oil deterioration and parts corrosion.

Q: Which brands of tank trucks and power take-offs (PTO) are compatible with this air compressor?

A: It is compatible with supporting PTOs for mainstream tank trucks and gearboxes including Sany, Sinotruk, FAW, Dongfeng, Mercedes-Benz and ZF. Any PTO with output torque ≥500Nm and power of 30-37kW can be matched. If proper matching cannot be confirmed, you may provide vehicle specifications and we will recommend suitable PTOs.

Q: How long shall the unit cool down before restarting after 120 minutes of continuous full-load operation?

A: After 120 minutes of continuous full-load operation, run the unit at low speed with no load for 5-10 minutes for heat dissipation before restarting. If operating under high ambient temperature above 35°C, a 15-minute cooling period is recommended to extend service life.

Q: What are the routine maintenance procedures and intervals for the air compressor?

A: ① Clean dust on the air intake filter before daily operation; ② Every 500 hours: clean the cooling fins and check pipelines for air leakage; ③ Every 3000 hours: disassemble and inspect wear of internal wear plates, replace consumables as required. No lubricating oil needs to be filled into the unit.

Q: What causes insufficient air flow and material blockage during unloading?

A: Four common causes: ① Clogged air intake filter leading to insufficient air intake; ② PTO rotating speed lower than 700r/min; ③ Damaged unloading pipelines or poorly sealed flanges causing air leakage; ④ Poor heat dissipation resulting in high temperature and power derating. Troubleshoot the above items in sequence to solve the problem.

Q: What customs clearance documents can be provided for export? Can the package be reinforced?

A: We can provide complete set of customs clearance documents free of charge, including CE certificate, packing list, commercial invoice and product specification sheet. Standard export packaging is solid wooden case, which can be thickened and reinforced upon request to suit long-distance ocean transportation.

Q: Is OEM private labeling and customized machine marking available?

A: OEM and neutral packaging customization are supported. We can replace machine nameplates and print customer LOGO on outer packages. Please contact our sales team to discuss customized requirements.

Q: Can wearing parts such as air intake filters, wear plates and gaskets be purchased separately?

A: Complete sets of wearing spare parts are available for separate retail with no minimum order quantity. Spare parts can be shipped together with air compressors or delivered separately.

Q: What payment terms are available for orders? Can samples be purchased for testing?

A: T/T wire transfer is the main settlement method, and L/C can be negotiated. Sample purchase is acceptable. Samples are charged at small-batch unit price. Sample fee can be negotiated for refund when placing subsequent bulk orders. Sample lead time is 5-7 days.

Q: Will the performance of the air compressor be affected when used at high altitudes?

A: Thin air at high altitudes will slightly reduce effective air displacement. It is recommended to appropriately increase operating speed to 800-900r/min and shorten the duration of each continuous operation.
