Screw Compressors Oman
Star Compressors supplies industrial rotary screw air compressors from 7.5 HP to 100 HP across Oman. Fixed speed, Variable Speed Drive (VSD), and silent models — all rated for Oman's extreme climate, backed by a 1-year service warranty and local after-sales support from Muscat to Salalah.
What Is a Rotary Screw Compressor?
A rotary screw compressor is an industrial-grade air compressor that uses two interlocking helical screw rotors to compress air continuously. Unlike piston compressors that compress air in pulses, a screw compressor delivers smooth, constant airflow — making it the preferred choice for factories, production lines, workshops, and any application requiring reliable continuous compressed air.
The rotary screw design means virtually no vibration, significantly lower noise levels, and a 100% duty cycle — the compressor can run all day, every day without overheating or requiring rest periods. This makes screw compressors the industry standard for serious industrial operations across Oman.
Star Compressors supplies rotary screw air compressors from 7.5 HP (5.5 kW) up to 100 HP (75 kW), available in fixed speed, Variable Speed Drive (VSD), and ultra-silent configurations — all rated for Oman's extreme operating conditions.

Switching from a piston to a screw compressor typically reduces energy costs by up to 35% and eliminates maintenance downtime across Oman's industrial facilities.
Types of Screw Compressors We Supply in Oman
Three configurations to match every application, budget, and industry requirement across Oman's diverse industrial sector.
Fixed Speed Screw Compressors
The reliable workhorse for consistent, constant air demand. Fixed speed screw compressors run at a set motor speed to deliver continuous, steady airflow — ideal for manufacturing lines, spray painting, sandblasting, and any application where air demand is stable throughout the working day.
Available from 7.5 HP to 100 HP with 8 bar and 10 bar pressure options. Low maintenance, 100% duty cycle, and designed to operate continuously in Oman's high-temperature environment without performance loss.
VSD Variable Speed Drive Screw Compressors
The intelligent choice for businesses with varying air demand throughout the day. VSD (Variable Speed Drive) compressors use an inverter to automatically adjust motor speed to match exactly how much compressed air you are using at any given moment — eliminating wasteful idling that costs money.
Save up to 35% on electricity compared to fixed speed models. Smart controller monitors pressure, temperature, and run hours in real time. Ideal for factories, workshops, and production facilities where air demand fluctuates across shifts.
Silent Screw Compressors
Sound-insulated screw compressors operating below 65 dB — quieter than a normal conversation. The cabinet-enclosed design absorbs vibration and noise completely, making these compressors suitable for office-adjacent workshops, dental clinics, laboratories, showrooms, food preparation areas, and any environment where noise impacts staff or customers.
Full rotary screw performance and 100% duty cycle in a sleek, compact cabinet. Available in fixed speed and VSD configurations.

Key Features of Star Screw Compressors
Every screw compressor in our range is selected and configured specifically for Oman's demanding operating conditions — extreme summer heat, dusty and sandy environments, and the rigorous continuous-use demands of Oman's expanding industrial sector.
These are not generic imported machines. They are proven industrial compressors that meet the specific challenges of running compressed air equipment in the Sultanate of Oman.
Quick Specifications
High-Temp Rated Airend
The compressor airend — the heart of the machine — is rated to operate reliably in ambient temperatures up to 50°C. During Oman's summer months when workshop temperatures regularly exceed 45°C, standard imported compressors overheat and shut down. Our compressors keep running.
Intelligent Controller
Every compressor is equipped with a microprocessor controller displaying real-time pressure, temperature, run hours, load percentage, and service alerts. Remote monitoring capability is available on VSD models, allowing your team to track compressor performance without being physically present at the machine.
IP54 Dust and Sand Protection
Motors and electrical components are fully enclosed to IP54 rating — protecting against dust ingress and sand infiltration that causes premature failure in Oman's industrial and desert environments. The inlet filtration system is also designed for high-particulate environments to protect the airend.
Premium IE3 Efficiency Motors
All Star Compressors use premium IE3 super-efficiency electric motors that exceed international efficiency standards. Higher motor efficiency means less electricity consumed, less heat generated, and a lower operating cost every single hour your compressor runs — which in an industrial Oman environment is significant savings over the machine's lifetime.

Frequently Asked Questions About Screw Compressors in Oman
Everything you need to know before buying a rotary screw air compressor in Oman — answered by our technical team.
For a small workshop in Oman — automotive garage, woodworking shop, spray painting booth, or general maintenance — a 7.5 HP or 10 HP fixed speed screw compressor is typically the right choice. It delivers 100% duty cycle, low noise, and clean dry air without the size and cost of a larger unit. WhatsApp us your application and we will confirm the exact specification and size you need.
Screw compressor prices in Oman vary based on HP, type (fixed speed or VSD), and whether accessories such as a dryer, filter, and receiver tank are included. WhatsApp or call us on +968 9548 2001 with your requirements and we will provide a transparent, itemised quote with no hidden charges. We offer competitive pricing and flexible options to suit all budgets.
Yes — in most cases. If your air demand varies throughout the day (which is true for the majority of Oman's workshops and factories), a VSD compressor will save up to 35% on electricity costs compared to a fixed speed model. Given Oman's electricity costs and the long daily run hours typical of industrial operations, the additional investment in a VSD unit typically pays back within 12–24 months through energy savings alone.
Yes — all Star Compressors screw compressors are rated for ambient operating temperatures up to 50°C, which covers even the hottest Omani summer conditions in workshops and industrial buildings. The high-temperature airend and motor are specifically selected for this operating environment. Standard imported compressors rated for 40°C or less will overheat and shut down frequently in Oman's summer — ours will not.
The right HP depends on your required air flow (CFM or m³/min) and working pressure (bar). Simply WhatsApp or call us and tell us: (1) what tools or machines will use the air, (2) how many will operate simultaneously, and (3) how many hours per day you need compressed air. Our technical team will calculate your exact air demand and recommend the correct HP and configuration — free of charge with no obligation.
Yes — in virtually all applications. All screw compressors produce some moisture in the compressed air, and in Oman's humid climate this moisture content is significant. Without a refrigerated air dryer, water will accumulate in your pipelines, corrode your air receivers, damage pneumatic tools and cylinders, and ruin spray paint finishes. A properly matched air dryer is an essential part of any quality compressed air system. We supply and install the correctly sized dryer for every compressor we sell.
Standard servicing intervals for screw compressors are typically every 2,000 to 4,000 run hours, depending on the model and operating conditions. In Oman's dusty, high-temperature environment, we recommend servicing at the lower end of this range. A typical service involves oil change, air-oil separator replacement, inlet filter change, belt inspection, cooler cleaning, and controller check. Our AMC contracts handle all of this on a scheduled basis so you never miss a service interval.
Yes. Star Compressors delivers, installs, and services screw compressors across all of Oman — Muscat, Sohar, Salalah, Nizwa, Sur, Duqm, Barka, Ibri, Rustaq, and all other locations. Contact us to discuss delivery and installation logistics for your specific location anywhere in the Sultanate.
