Explore our state-of-the-art permanent magnet, variable frequency, and silent rotary screw systems designed for modern industrial applications.
Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise founded in early 2004. Located at No. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China, our advanced facility has evolved into a premier base for manufacturing twin-screw air compressors, high-precision scroll systems, and customized industrial air system solutions.
We supply a comprehensive suite of compressed air systems to international buyers: from robust low, medium, and high-pressure piston compressors to energy-conserving 3KW-480KW variable frequency screw and scroll models, gas separation equipment, refrigerant dryers, and advanced filtration units.
Achieving high-grade energy efficiency relies on specific structural advantages of scroll and twin-screw air compressors.
Our VSD PM (Variable Speed Drive Permanent Magnet) technology controls energy loss by adjusting motor rotational speeds to match real-time demand. This eliminates unload cycles, saving up to 35-50% in electricity overheads, maintaining Level 1 energy efficiency ratings.
Dividing the pressure ratio across two distinct stages keeps the internal thermodynamic temperature close to isothermal. Interstage cooling lowers input power demands, optimizing volumetric output while lowering rotor stress levels.
Designed for sterile sectors (biotech, medical devices, semiconductors). Dry-type oil-free screw and high-efficiency scroll designs ensure zero liquid oil bypass, protecting downstream systems from critical residue deposits.

Decades of optimization reflected in reliable factory specifications.
Sourcing from our factory in Malu Town, Jiading District, Shanghai, grants global distributors access to a highly integrated industrial cluster. This localized manufacturing ecosystem provides significant competitive advantages:
We focus on regulatory compliance to minimize import friction for distributors and end-users. All units are configured to meet local safety, electrical, and pressure directives before dispatch.
How our custom compressor systems match specific workspace operational environments.
Fiber laser systems require high-pressure gas (often up to 20 bar) to blow molten metal out of the cut zone, ensuring a clean edge. Our specialized 20-bar screw compressors provide continuous pressure, reducing dross and post-process cleanup.
For workshops with limited floor space, our Four-in-One system combines a screw compressor, 300L/500L receiver tank, refrigerant dryer, and heavy-duty pre/post filters into a single unit. Its insulated enclosure keeps noise levels below 68 dB(A).
For heavy manufacturing, packaging lines, and chemical processing, our high-precision micro-oil rotary screw vacuum pumps deliver consistent, deep negative pressure, helping stabilize sensitive operations.
Technical answers to help buyers evaluate scroll and screw compressor options.
Scroll compressors use an orbiting scroll and a fixed scroll to compress air in continuous pockets, which is ideal for lower flow applications. Twin-screw compressors use two intermeshing helical rotors, which is better suited for high-flow, high-power industrial applications. Both options are available with variable frequency (VSD PM) drives to improve efficiency.
A fixed-speed compressor runs at maximum speed and unloads when demand drops, wasting energy while keeping the motor spinning. A permanent magnet VSD system adjusts the motor speed to match air consumption in real time, reducing power draw during low-demand periods and eliminating energy waste.
Yes, we custom-configure our electrical systems during assembly. We offer 220V 50Hz single-phase systems for light commercial workshops, as well as 380V/415V/460V three-phase configurations for global industrial grids.
Dry oil-free systems do not have oil in the compression chamber, which reduces the need for oil separator replacement. Maintenance focus shifts to replacing air intake filters, checking the condensate drain system on the dryer, and monitoring the seals and interstage cooling system to ensure longevity.
