AS0.9-7.5G Scroll Air Compressor

The AS0.9-7.5G Scroll Air Compressor is a third-generation positive displacement machine built around an orbiting scroll and fixed scroll pair. The model designation indicates a 7.5 kW motor rating and 0.9 m³/min nominal free air delivery, though buyers should confirm the exact displacement and pressure rating with Shaanxi Science Compressor directly. The source text highlights a key mechanical trait: the absence of suction and exhaust valves, which eliminates valve percussion noise and the associated energy losses from valve resistance. With a tip speed kept below 2 m/s, friction losses are reduced and mechanical efficiency is claimed to exceed that of equivalent piston and screw alternatives.

The host structure uses fewer parts than a conventional piston compressor (claimed at one-eighth the component count), with no contact between the precision-machined scroll wraps during normal operation. This non-contact running is possible because of an oil-free or minimal-lubrication design that relies on precise orbital geometry rather than metallic contact sealing. The typical scroll wrap material is high-grade cast aluminium or grey iron with a PTFE-based coating, though the exact material specification for this unit is not stated. Clearance volume is minimal, giving volumetric efficiency approaching 100 percent, a standard characteristic of scroll compressors in good condition. The unit ships in a wooden case, suggesting factory packaging suitable for sea freight or air cargo.

This compressor suits applications where low noise, compact footprint, and minimal vibration are priorities: medical air systems, laboratory instrumentation, food and beverage pneumatic controls, and precision electronics manufacturing. The 50 dB operating level makes it viable for installation near workstation areas without extensive acoustic treatment. Importers should note that the response rate for Shaanxi Science Compressor is currently zero, so direct enquiry through the listed address on Jincheng Road, Xianyang, Shaanxi, is essential to confirm lead time, Incoterms, and after-sales parts availability. Voltage, frequency, and phase configuration should be specified at order stage to ensure motor compatibility with local grids.

Shaanxi Science Compressor Co., Ltd. is located on Jincheng Road in the manufacturing equipment district of Xianyang, Shaanxi Province, China, with postal code 713100. The company is classified under an imported supplier tier and holds a harbor trust tier classification on the platform. These tier labels indicate a registered business with basic verification, though they do not substitute for independent due diligence by prospective buyers. The current response rate is recorded at 0.00 percent, with an average response time of zero hours, meaning no enquiry response data is available. This absence of engagement metrics should prompt buyers to initiate direct contact and assess communication responsiveness before placing orders.

The listing presents the AS0.9-7.5G as a scroll air compressor with emphasis on energy efficiency, low noise, and reduced maintenance compared with piston and screw alternatives. No information is provided about year of establishment, production floor area, annual turnover, number of employees, export markets served, or ISO/CE certification status. Buyers should request copies of quality management system certificates, factory inspection reports, and reference installations. Given the zero response signal, it is prudent to verify whether the company is actively monitoring enquiries or if an alternative contact channel (telephone, trade show representative, or local agent) yields faster communication.
