Screw Air Compressor Selection Guide
Find the right UMW Air compressor for your airflow, pressure and application—from compact workshops to large industrial installations and mobile operations.
Define your needs
Start with Your Air Requirements
These basic details determine compressor size, configuration and air-treatment requirements.
Required Airflow
Add the air used by scew air compressor operating at the same time.
Working Pressure
Confirm pressure at the point of use and allow for system losses.
bar / psi
Operating Hours
Is demand steady, intermittent or variable during the working day?
Hours per day
Air Quality
Define moisture, particle and oil limits required by the processing technology.
Process requirements
Site Conditons
Check power, ambient temperature, ventilation and installation space.

Choose the Right UMW Air Series
Compare power ranges and system layouts to narrow down your options.
| Series | Power Range | System Layout | System Equipment | Typical Selection Needs |
|---|---|---|---|---|
| Micro Series | 4–7.5 kW | Compact integrated | 140 L receiver + dryer + filters | Smaller air demand and limited space |
| Prime Series | 11–22 kW | Industrial integrated | 340 L receiver + dryer + filters | Small to medium production lines |
| Core Series | 30–110 kW | Separate cabinet | Configurable air-treatment equipment | Larger demand and flexible installation |
| Mega Series | 132–355 kW | High-volume system | Separately selected system equipment | Large industrial and centralized supply |
| Portable Diesel Series | 75–700 hp | Mobile diesel-powered | Towable chassis; model-specific equipment | Outdoor sites without electrical power |

Plan the Complete Air System
A compressor is only one part of a reliable clean-air installation.
Integrated or Separate?
Select the layout that matches your air demand, available space and maintenance requirements.
Micro / Prime
Compressor, receiver, dryer and filters in one integrated package.
Core / Mega
Separate equipment selected around airflow, pressure and air-quality needs.
Portable Diesel
Mobile compressed air for off-grid and outdoor operations. Air-treatment equipment is selected when required.
Before final selection
Check the Installation Conditions
Confirm the site before finalizing compressor size and accessories.
-
Power Supply
Voltage, frequency, phase and available capacity. -
Service Space
Access for installation and routine maintenance. -
Condensate
Drainage and condensate treatment plan.
-
Ventilation
Sufficient cooling airflow and keep ambient temperature. -
Pipework
Diameter, length and expected pressure loss. -
Backup Air
Continuity during maintenance or shutdown.
FAQ
Screw Air Compressor Selection FAQs
Quick answers to common questions about sizing and system configuration.
01. How do I determine the required airflow?
Add the air consumption of equipment operating simultaneously, then review peak demand and planned expansion. If figures are unavailable, send us the equipment specifications.
02. Can I choose a compressor by motor power alone?
No. Compare air delivery at your required working pressure. Motor power alone does not confirm whether the compressor can meet your demand.
03.Should I choose a variable-speed compressor?
Variable-speed operation may suit changing air demand. Share your demand pattern and operating hours so we can review the appropriate option.
04. Do I need a receiver, dryer and filters?
The configuration depends on demand fluctuations and air quality. A receiver provides storage, while dryers and filters address moisture and contaminants.
05. Does food production always require an oil-free compressor?
Requirements depend on how air is used and whether it contacts the product. Confirm your required air quality before selecting a compressor and treatment equipment.
06. What if I do not know my airflow or pressure?
Send your application, equipment details and operating hours. Photos, manuals or an existing compressor nameplate can help us review your requirements.
