Featured 30 HP & Engineered Compressed Air Systems
Explore our flagship heavy-duty rotary screw units, PM VFD variable speed models, oil-free water-lubricated units, and explosion-proof skids manufactured at our Jiading, Shanghai factory.
30 HP (22 kW) Rotary Screw Architecture & Thermodynamics
In modern industrial utility rooms, the 30 Horsepower (22 Kilowatt) rating represents the global benchmark for decentralized and continuous manufacturing air supplies. Shanghai Honest Compressor optimizes this thermodynamic footprint via third-generation asymmetric 5:6 helical screw profiles.
Isothermal Compression Efficiency
Standard polytropic compression releases massive parasitic thermal waste. Our 30 HP air ends inject atomized, temperature-regulated lubricant directly into the compression pocket, flattening the polytropic index close to isothermal levels. This eliminates internal air blow-by and preserves volumetric efficiency up to 96.8% across full operational pressure bands (7 to 13 bar).
IE5 Ultra-Premium PM Motor Drive
Unlike traditional induction motors suffering from rotor copper losses and slip, our permanent magnet synchronous motors (PMSM) maintain an IE5 efficiency curve even at 25% partial load. High-coercivity NdFeB magnets resist demagnetization up to 180°C, direct-coupled via 1:1 coaxial shafts without gearbox slippage or transmission loss.
Dynamic Back-Pressure Acoustic Design
Acoustic dampening is engineered natively into the chassis. High-rigidity ductile iron housings minimize vibration transmission, paired with internal centrifugal oil separation tanks with multi-stage labyrinth filtration. Operational noise remains dampened between 62 to 68 dB(A), complying with stringent indoor workplace safety mandates worldwide.

Total Cost of Ownership & Industrial Decarbonization
Over a standard 10-year operating horizon (approx. 50,000 run-hours), procurement cost represents merely 10% to 12% of a 30 HP compressor’s total financial footprint. Electricity consumption comprises 76% to 80% of aggregate expenditures.
Elimination of Unloaded Idling Penalties
Traditional fixed-speed compressors continue consuming 40% to 45% of full-load power while running unpressurized during factory shift transitions. Honest Compressor’s Permanent Magnet VSD modulates motor frequency dynamically from 15 Hz to 60 Hz in milliseconds, tracking actual facility air demand down to 0.1 bar tolerance and eliminating wasted idle kilowatts.
Integrated Waste Heat Recovery Modules
Mechanical air compression inherently converts over 90% of electrical energy into high-temperature oil and air heat. Our factory provides optional factory-integrated Plate Heat Exchanger (PHE) packages. These channel thermal energy into boiler feed pre-heating, plant district heating, or CIP wash processes, achieving zero-emission hot water up to 75°C.
Harmonic & Power Grid Compliance
Variable speed inverters can induce severe electrical resonance and harmonic degradation into factory substations. We incorporate built-in DC reactors and line filters conforming to IEEE 519 and EN 61000-3 standards, delivering a Total Harmonic Distortion (THD) under 5% and maintaining plant power factors consistently at 0.98+.

Frequently Asked Engineering & Sourcing Questions
Clear, technically rigorous answers addressing sizing, energy payback periods, maintenance intervals, and import procedures for 30 HP / 22 kW air compressors.
How many CFM or m³/min does a 30 HP rotary screw air compressor produce?
Under standard reference conditions (ISO 1217 Annex C, 20°C, 1 bar absolute), a high-efficiency 30 HP (22 kW) single-stage screw air compressor delivers between 3.60 m³/min and 3.85 m³/min (127 to 136 CFM) at 8 bar (116 psi) discharge pressure. At 10 bar (145 psi), output is approximately 3.20 m³/min (113 CFM), while our 20-bar laser boost configurations deliver 2.45 m³/min (86.5 CFM). Two-stage models boost 8-bar capacity up to 4.10 m³/min (145 CFM).
What is the realistic financial payback period when upgrading to a 30 HP PM VFD?
For industrial facilities with air consumption variations of 30% or more, upgrading from a fixed-speed load/unload compressor to an Honest PM VFD system typically saves 25% to 38% in electrical consumption. Operating 6,000 hours per year at an industrial electricity tariff of $0.12/kWh, annual power savings average $5,500 to $7,800. This yields a full capital expenditure payback on the machine within 9 to 14 months.
When is a Water-Lubricated Oil-Free compressor necessary over an oil-injected unit?
Standard oil-injected compressors with downstream coalescing filters can achieve 0.01 ppm residual oil carryover, which suffices for general workshops and structural fabrication. However, in pharmaceuticals, electronics SMT, brewery aeration, and medical packaging, any risk of hydrocarbon contamination is unacceptable. Our EOWV series utilizes sterile purified water for cooling and seal lubrication, guaranteeing ISO 8573-1 Class 0 certified air with zero hydrocarbons in the air stream.
How does the Honest Compressor Shanghai factory support international warranty and spare parts?
We supply complete operational spare kits (intake filter elements, spin-on oil separators, synthetic lubricants, thermostatic valve cores) configured for 2,000, 4,000, and 8,000-hour service routines. We maintain master distributor spares hubs across Western Europe, Southeast Asia, and South America for dispatch within 24 to 48 hours, alongside complete video maintenance guides and remote factory engineering support.
Can our factory customize voltage, frequency, and controller languages for OEM orders?
Yes. As a direct OEM/ODM manufacturer, Honest Compressor configures electrical panels to meet any local utility grid: 208V/220V/230V/240V/380V/400V/415V/460V/480V in both 50 Hz and 60 Hz. Our PLC touch screen controllers feature 12 pre-programmed operational languages, including English, Spanish, French, German, Russian, Arabic, and Vietnamese, alongside custom branding colors and logos.
What are the primary installation requirements for a 30 HP / 22 kW compressor room?
We recommend a minimum room clearance of 1.0 meter around the enclosure for cooling ventilation and maintenance access. For ambient temperatures exceeding 40°C, positive-pressure ducted exhaust fans should be installed to prevent hot air recirculation. Electrical supplies require a dedicated 60A/380V or 100A/220V breaker, paired with an appropriately sized receiver tank (minimum 600 to 1,000 liters) to buffer line pressure during peak downstream load spikes.
