Energy-Saving Single Stage VSD Screw Air Compressor with 63dB Low Noise and G1-1/4" BSPT Port for Easy Installation

This FI-22AFC single stage variable speed drive (VSD) screw air compressor is equipped with frequency-regulated single-stage screw airend, delivering wide flow ranges across three pressure tiers: 0.89-4.65 m³/min at low pressure 7.5/8.5bar, 0.82-3.75 m³/min at standard 10/12.5bar, and 0.68-3.1 m³/min at high pressure 13/15.5bar, covering a total pressure range of 7.5~15.5bar. The VSD system dynamically adjusts air output according to on-site demand, eliminating unloaded waste and significantly reducing power consumption. The universal G1-1/4" BSPT exhaust port enables direct connection with standard industrial pipes and post-treatment equipment. With compact overall dimension 1350×850×1700mm, its vertical structure saves factory floor space, and the 559kg robust body minimizes running vibration. Operating noise is as low as 63dB(A), requiring no extra soundproof room. The energy-efficient VSD single-stage screw design delivers stable performance for non-stop 24-hour air supply, ideal for fluctuating medium-large air demand in machining, spraying, auto repair and packaging industries. Our factory manufactures full range single & two-stage screw compressors, air receivers, refrigerated dryers and precision filters, with OEM & ODM customization for global industrial clients.

Our factory specializes in R&D, manufacturing and export of industrial screw air compressors and matching air treatment equipment. The FI-22AFC single stage VSD screw compressor is our energy-saving flagship model for medium-scale factories, combining high variable flow capacity, low noise and outstanding operational reliability. Powered by variable-frequency single-stage screw rotor airend, it provides three pressure tiers with wide adjustable flow ranges: low pressure 7.5/8.5bar delivers 0.89~4.65 m³/min high volume for fluctuating large-flow demand in light industry, packaging and textiles; standard 10/12.5bar outputs 0.82~3.75 m³/min covering most machining, auto repair, spraying and pneumatic tool scenarios; high pressure 13/15.5bar supplies 0.68~3.1 m³/min for special high-pressure tasks like bottle blowing, pressure testing and leak detection. The VSD system adjusts motor speed in real time according to actual air consumption, eliminating the energy waste caused by unloaded idling on traditional fixed-speed compressors and delivering remarkable long-term electricity savings.

Q1: What is the model number, and what are the flow ranges for each of the three pressure tiers? A1: Model: FI-22AFC. Low pressure 7.5/8.5bar: 0.89-4.65 m³/min; standard 10/12.5bar: 0.82-3.75 m³/min; high pressure 13/15.5bar: 0.68-3.1 m³/min. Q2: What is the exhaust port specification, overall dimension, noise level and net weight? A2: Exhaust port: BSPT G1-1/4"; overall size: 13508501700mm; noise: 63dB(A); net weight: 559kg. Q3: What type of air compressor is this, and what is the full pressure coverage range? A3: Single stage variable speed drive (VSD) screw air compressor; full pressure tier coverage spans 7.5~15.5 bar(g). Q4: What core advantages does VSD variable speed design have over standard fixed-speed compressors? A4: VSD compressors dynamically adjust motor speed to match actual air demand, eliminating wasted energy from unloaded idling. The greater the air demand fluctuation, the more significant the energy savings, resulting in lower long-term electricity bills. VSD also delivers more stable outlet pressure without frequent start-stop shock to the pipe network. Q5: What supporting equipment does our factory produce besides screw compressors, and what customization services are available? A5: We produce matching air receivers, refrigerated dryers and precision air filters for complete air treatment systems. OEM & ODM customization is available for working pressure, air flow, input voltage, body color and private brand logo labeling.
