    • Permanent Magnet Variable-Frequency Oil-Injected Screw Air Compressor BMVF7.5

    Permanent Magnet Variable-Frequency Oil-Injected Screw Air Compressor BMVF7.5

    The Kaishan BMVF7.5 is a 7.5 kW permanent‑magnet variable‑frequency oil‑injected screw air compressor. It features a high‑efficiency permanent‑magnet synchronous motor with a speed‑control range of 15–100%. The unit automatically adjusts its rated air delivery to match the workshop’s actual air demand, eliminating no‑load energy consumption and delivering 20–30% greater energy savings compared with line‑frequency compressors. With air‑cooled, single‑stage compression, it ensures long‑term, continuous, and stable operation in small to medium‑sized industrial workshops; its low oil content delivers clean compressed air for pneumatic equipment.

    Product Q&A

    What working conditions are horizontal directional drilling rigs primarily used for?

    It is primarily used for trenchless installation of underground pipelines and is suitable for the construction of crossings for telecommunications, gas, and water supply and drainage pipelines.

    Can a horizontal directional drilling rig penetrate both soil and rock formations?

    Standard models are suitable for soil layers; for rock formations, a rock‑drilling attachment kit must be selected.

    What is the maximum drilling depth achievable by a water well drilling rig?

    Drilling depths vary by model; standard models cover 100–350 meters, with options available to suit specific requirements.

    Is the water well drilling rig hydraulically driven, and does it support a diesel engine as its power source?

    The entire machine is hydraulically driven and can be equipped with either a diesel engine or an electric motor as its power source.

    Is a drilling rig suitable for constructing rural drinking-water wells and engineering dewatering wells?

    Fully applicable and widely used for domestic drinking wells, agricultural irrigation wells, and construction dewatering wells.

    Is the wheeled pile driver easy to move, and does it require trailer transport?

    The wheeled chassis is self-propelled and can move under its own power over short distances; for long-distance transport, towing is recommended.
