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: What specifications of PTO are compatible with the BDW-14/2 air compressor?

A: A heavy-duty PTO with rated output torque ≥500Nm and power of 35–45kW is required. Our 700Nm models such as 60X, 50C-CH8 and 50CH8 are all suitable. You may provide your vehicle gearbox model, and we will offer a complete driving solution.

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

A: Under standard working conditions, run at low speed with no load for 5–10 minutes before restart. In high-temperature regions where ambient temperature＞35°C, extend the cooling period to 15 minutes to protect heat dissipation components.

Q: What is the complete routine maintenance schedule for the air compressor?

A: Clean dust from the air intake filter before daily operation; clean cooling fins and check pipelines for air leakage every 500 working hours; disassemble and inspect wear of wear plates and sealing parts every 3000 working hours. No compressor oil needs to be filled into the unit.

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

A: Common triggers: ① Severely clogged air intake filter; ② PTO operating speed lower than 700r/min; ③ Air leakage on unloading pipelines and flange seals; ④ Poor heat dissipation leading to high temperature and power derating. Carry out inspection and repair in sequence.

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

A: We provide CE certificate, commercial invoice, packing list, product specifications and HS code information free of charge. Fumigated solid wooden cases are standard packaging. Extra cushioning protection can be added upon request to avoid deformation caused by collision during ocean transportation.

Q: Is OEM customization available for machine LOGO, nameplates and outer packages?

A: Yes. Custom machine marking and customer brand printing on outer packages are supported. The lead time for customized orders follows the schedule for bulk orders.

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

A: Wearing spare parts are available for separate purchase with no minimum order quantity. Parts can be shipped together with main units or delivered separately.

Q: Is sample purchase available? How to settle the sample fee?

A: Single-unit samples are available for testing at small-batch unit price. The sample fee can be negotiated for deduction when placing subsequent bulk repeat orders. Sample lead time is 5–7 days.

Q: Will high-altitude use affect the performance of the air compressor?

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

Q: What advantages does the 14m³/min air compressor have compared with the 12.5m³ model?

A: Larger air displacement enables faster unloading. It is the preferred option for large-volume powder tanks and easily blocked materials such as lime and fly ash, reducing waiting time for unloading and improving fleet turnover efficiency.

Q: How to deal with excessively high operating temperature of the air compressor?

A: Remove dust accumulated on cooling fins; appropriately shorten continuous full-load working duration; check whether the PTO speed exceeds the limit; clean the air intake filter to ensure smooth air intake.
