  • Q What certificates do you have?

    A

    Our whole product line owns ISO nine thousand and one quality‑system certificate, CE certificate, plus multiple invention and utility‑model patents. Export documents can be supplied for overseas customs clearance.

  • Q Do you support remote monitoring?

    A

    Most of our new‑model compressors, blowers and vacuum pumps support remote monitoring function. Some models need optional IoT module. Leave your message in inquiry, we will confirm for you.

  • Q What advantages for your permanent‑magnet VFD screw compressor?

    A

    Our permanent‑magnet variable‑frequency screw compressor can save thirty‑five to forty percent power compared with fixed‑speed models. Air‑cooled design supports long‑hour heavy‑duty running. Intelligent touch‑screen with full‑range protection. Wide power range from seven point five kilowatts up to three hundred and fifteen kilowatts.

  • Q Which industries are suitable for this screw compressor?

    A

    It is widely used for general workshops, machinery processing, auto parts, textile, building‑material factories. It is standard choice for common industrial compressed‑air demand.

  • Q Why choose your four‑in‑one laser‑cutting air compressor?

    A

    All‑in‑one integrated unit includes screw host, refrigerated dryer, air‑receiver tank and multi‑stage precision filters. It supplies ultra‑dry, ultra‑clean air to protect laser lens. Working pressure supports sixteen bar and eighteen bar. Plug‑and‑play, save installation time and workshop space.

  • Q Can it work for fiber laser machine?

    A

    Yes, specially developed for fiber laser cutting machine. Oil content reaches zero point zero one parts‑per‑million, filtering precision zero point zero one micrometer. Perfect for metal sheet laser cutting production.

  • Q What is Class zero oil‑free air standard?

    A

    ISO eight five seven three‑one Class zero is the highest‑grade oil‑free compressed‑air standard. Our water‑lubricated screw, dry‑type screw and oil‑free scroll compressor all can reach this standard for one‑hundred‑percent oil‑free output.

  • Q Difference between water‑lubricated screw and dry‑type oil‑free screw?

    A

    Water‑lubricated series uses water for internal lubrication, higher energy‑saving performance, lower running temperature. Dry‑type LY‑DRYPM two‑stage screw compressor runs without water inside air circuit, suitable for projects that cannot accept moisture in compressed air.

  • Q When should I pick oil‑free scroll compressor?

    A

    Oil‑free scroll compressor fits small‑scale demand: laboratories, medical clinics, small‑size food workshops. We have standalone, two‑in‑one and four‑in‑one skid‑mount versions, power from one point five kilowatts to thirty‑eight point five kilowatts.

  • Q What industries need Class‑zero oil‑free compressor?

    A

    Pharmaceutical, food‑beverage, lithium‑battery electronics, textile, medical equipment, aseptic‑packaging industries must use Class‑zero oil‑free compressed‑air equipment.

  • Q What is advantage compare with roots blower?

    A

    Our oil‑free screw blower saves twenty to forty percent energy versus traditional roots blower. Max boost pressure reaches two hundred kilopascals. Lower noise, stable flow under changing back‑pressure. Mainly used for sewage‑treatment aeration, pneumatic conveying, chemical‑industry process.

  • Q Is blower output air oil‑free?

    A

    Yes. Adopting labyrinth plus spiral combined sealing structure, compression cavity is fully isolated from lubrication cavity, output one‑hundred‑percent oil‑free air.

  • Q Difference between screw vacuum pump and water‑ring pump?

    A

    Our LY‑VP dry‑type screw vacuum pump runs without water medium, no sewage discharge. It saves twenty to forty‑percent power compared with water‑ring pump and roots vacuum pump. With anti‑corrosion coating for corrosive gas working condition.

  • Q What application for your dry screw vacuum pump?

    A

    Widely used for chemical process, pharmaceutical production, electronic coating, vacuum packaging, material degassing process.

  • Q When to choose medium‑high pressure two‑stage screw compressor?

    A

    medium‑high‑pressure two‑stage screw compressor is for high‑pressure working condition, such as PET bottle blowing, pressure‑vessel pressure‑testing, special‑process laser cutting. It has long three thousand five hundred‑hour maintenance cycle.

  • Q What about air quality for medium‑high pressure compressor?

    A

    Built‑in water‑oil separation system, outlet oil content is below zero point zero one parts‑per‑million. It can supply clean compressed air for high‑demand production lines.

  • Q How can I get quotation and technical datasheet?

    A
