Explore our top-performing configurations, engineered for heavy-duty applications requiring constant pressure, clean air output, and maximized energy savings.
The industrial landscape is undergoing a massive transformation driven by carbon neutrality goals, soaring energy prices, and the rise of smart factory automation. Within this framework, 175hp (approximately 132kW) rotary screw compressors have emerged as the utility workhorse for heavy industries. Delivering between 700 to 900 cubic feet per minute (CFM) of compressed air, these machines provide the ideal balance of volumetric output and space-efficient footprints.
Historically, fixed-speed compressors dominated manufacturing floors, venting excess energy through mechanical modulation and modulation valves. Today, Permanent Magnet Variable Speed Drive (PM VSD) and Two-Stage Compression technology represent the state-of-the-art. PM VSD systems adapt motor speeds directly to real-time air demands, slashing electricity draw by up to 35% to 50% compared to traditional configurations. By eliminating unloading losses and high startup currents, these systems dramatically lower carbon footprints while optimizing factory operations.
Modern global enterprises mandate compliance with MEPS (Minimum Energy Performance Standards) and European Ecodesign standards. Our 175hp compressors meet and exceed Class 1 energy efficiency requirements.
Interoperability with Modbus RTU, Profibus, and cloud-based telemetry allows facility engineers to monitor system pressure, temperature, and maintenance intervals remotely.
Purchasing large-scale machinery like a 175hp compressor goes beyond the upfront capital expenditure (CAPEX). Smart procurement directors evaluate Total Cost of Ownership (TCO).
While the initial purchase price of high-efficiency VSD air compressors is slightly higher than fixed-speed equivalents, electricity usage accounts for over 70% of a compressor's TCO over a 10-year lifecycle. Upgrading to VSD recovers the initial premium within 12 to 18 months through drastically lowered utility bills.
Different industrial landscapes require localized electrical configurations. We customize our motors and electrical control panels to match standard regions: 380V/50Hz for Europe/Asia, 460V/60Hz for North America, and 415V/50Hz for Australasia and parts of South Asia. Dual-frequency and multi-voltage options are also available.
Operating in harsh environments (e.g., mine sites in Western Australia or chemical plants in the Middle East) requires high-capacity air cooling systems, heavy-duty air filtration, and IP55 or IP65 electrical enclosures. Our industrial cabinets protect inner workings from ambient temperatures up to 50°C (122°F).

Smart Air Machinery (Linyi) Co., Ltd., established in 2005, is a diversified manufacturing enterprise integrating product research and development, production, and sales. Located in Linyi, the logistics capital of China, our company has accumulated rich production experience, strong technical capabilities, a top-notch R&D team, and complete testing equipment through over 20 years of diligent research and continuous innovation.
Our products, known for their aesthetically pleasing design, meticulous material selection, exquisite craftsmanship, and superior quality, are sold worldwide and have received widespread acclaim from customers. We primarily manufacture screw air compressors, piston air compressors, air storage tanks, and related machinery parts.
Deep-rooted in the logistics heart of China, we provide fast shipping networks and highly competitive raw material procurement. This enables us to export superior machinery at factory-direct pricing.
Smart Air is committed to building a leading brand in China's air compressor industry. We firmly implement our own brand strategy, adhere to the principle of honest business practices, prioritize customer service, continuously strengthen our production capabilities, and constantly enhance our brand influence.
We firmly believe that "quality creates reputation," "reputation creates brand," and "brand creates market." Currently, we have become a well-known and advanced enterprise in the industry, trusted by partners globally.
Our solutions feature state-of-the-art rotary screw profiles, oil-lubricated high-temp resistant bearings, and smart control panels designed for heavy-duty industrial environments.
An air compressor is not an isolated component. For industrial applications, achieving clean, dry, and reliable compressed air requires a holistic engineering system.
We supply robust Air Storage Tanks designed to handle the heavy output of a 175hp compressor. Tanks act as buffers, minimizing pressure drops during high-demand intervals, dampening pulsations, and dropping moisture out of the air stream before it reaches point-of-use equipment.
For sensitive setups like medical, pharmaceutical, and food packaging, air quality is non-negotiable. Our High-Efficiency Air Filters remove particulates down to 0.01 micron, and our matching dryers bring pressure dew points to optimal industrial limits, avoiding rust in downstream pipes.
Our heavy-duty two-stage screw air compressors split the compression ratio across two separate rotors. This lowers the internal thermal load, reduces volumetric leakage, and achieves high airflow delivery (FAD) while drawing less electrical power than single-stage alternatives.
With a proven track record of successful collaborations in over 20 countries, including the USA, Canada, Colombia, Chile, Australia, New Zealand, Russia, Indonesia, Vietnam, Malaysia, India, Sri Lanka, Bangladesh, Pakistan, Dubai, Afghanistan, Israel, Syria, Kosovo, Tunisia, and Angola, we are committed to meeting the diverse needs of our clients.
Since its establishment, the company has successively received numerous honors, including "China Famous Brand," "China's Preferred Brand for Green and Environmentally Friendly Products," "Top Ten Foreign Trade Enterprises in the Mall," "High-Tech Enterprise," "3A Credit Enterprise," and "Civilized and Trustworthy Unit."

As factories transition toward Industry 4.0, compressor design is shifting from mechanical efficiency to intelligent system integration. We are investing in several R&D directions to support this transition:
By connecting multiple 175hp and smaller VSD units to a central PLC, our systems load and unload compressors dynamically based on real-time plant demand. This prevents motor cycling and keeps pressure variations within ±0.1 bar.
We are transitioning our 175hp systems to next-generation liquid-cooled permanent magnet motors. These motors maintain IE5-level efficiency even when operating at low capacity (e.g., 20% to 30% load) during off-peak shifts.
Using advanced computational fluid dynamics (CFD), we have designed airflow cooling paths that damp noise propagation. This lowers our 175hp rotary screw compressor sound profiles to between 68 and 72 dB(A), supporting safe work environments.
