Hiraba Engineers is a rotary screw air compressor manufacturer and exporter serving industrial customers in India and international markets. We supply reliable compressed-air solutions for manufacturing plants, workshops, process industries and other applications where a continuous supply of compressed air is required.
Our range includes different screw compressor configurations based on air demand, pressure, operating hours and application. We also manufacture and supply compressor spare parts for customers looking to maintain or repair their existing equipment.
If you are planning a new installation or replacing an existing compressor, our team can help you select a suitable solution based on your actual operating requirements.
Rotary Screw Compressor Range
Hiraba Engineers offers rotary screw compressors for diverse industrial applications, including oil-flooded, oil-free, and variable-speed models. Each compressor can be selected based on required airflow, pressure, duty cycle, and operating conditions to deliver reliable and efficient performance.
Oil-Flooded Rotary Screw Compressors
Oil-flooded screw compressors are widely used in industrial applications that require a reliable and continuous supply of compressed air. During compression, oil circulates through the airend to provide lubrication, cooling, and sealing, after which it is separated from the compressed air before delivery to the plant. These compressors are suitable for a broad range of applications, including manufacturing plants, automotive industries, engineering workshops, textile units, packaging, construction, and general industrial operations.
Variable Speed Screw Compressors
Compressed-air demand is not always constant. In many plants, air consumption increases and decreases depending on production activity.
A variable speed drive (VSD) compressor can adjust the motor speed according to the demand. This makes it useful for applications where the air requirement changes during the working day.
Selecting the right VSD system requires an understanding of the plant’s actual air consumption rather than simply choosing a compressor based on motor capacity.
Our team can review your operating conditions and help determine whether a variable-speed solution is appropriate for your application.

Oil-Free Rotary Screw Compressors
Some manufacturing processes require compressed air with strict limits on oil contamination. For these applications, an oil-free screw compressor may be considered.
Oil-free systems are designed differently from conventional oil-flooded compressors and are used where compressed-air purity is particularly important.
They can be suitable for applications in industries such as pharmaceuticals, food and beverage, healthcare, electronics and other sensitive production environments.
Heavy-Duty Screw Compressors for Industrial Applications
Some plants operate compressors for long hours under demanding conditions. In such environments, compressor selection needs to take into account more than just air capacity.
Factors such as operating pressure, duty cycle, ambient temperature, installation conditions and maintenance requirements can affect compressor performance.
Our industrial screw compressor solutions are intended for applications where reliable compressed air is an important part of daily production.

How Does a Rotary Screw Air Compressor Work?
A rotary screw compressor uses two interlocking helical rotors to compress air.
When the compressor starts, atmospheric air enters through the inlet. The rotating screw elements trap the air between their profiles. As the rotors continue turning, the available space becomes smaller and the air pressure increases.
In an oil-flooded design, oil is introduced during this process to lubricate the rotors, remove heat and help seal the compression chamber. The compressed air then passes through the separation system before being supplied to the application.
Because the compression process is continuous, screw compressors are widely used in plants where compressed air is needed for long operating periods.
Choosing the Right Screw Air Compressor
The largest compressor is not necessarily the right compressor for every plant. Correct sizing is important for both performance and operating cost.
Before selecting a machine, consider:
- Required air flow
- Working pressure
- Daily operating hours
- Variation in air demand
- Ambient conditions
- Required air quality
- Available electrical supply
- Installation space
- Maintenance requirements
A proper assessment of these factors can help avoid both undersizing and unnecessary compressor capacity.
Rotary Screw Compressor Spare Parts
Hiraba Engineers also manufactures and exports screw compressor spare parts for maintenance, repair and replacement requirements.
Depending on the compressor and application, the available components may include:
- Air filters

Frequently Asked Questions
What is a rotary screw air compressor?
A rotary screw air compressor uses two rotating screw elements to compress air continuously. It is commonly used in industrial applications where a steady supply of compressed air is required.
What is the difference between a screw compressor and a reciprocating compressor?
A screw compressor uses rotating screw elements and provides continuous airflow, while a reciprocating compressor uses pistons that move back and forth to compress air. The choice depends on factors such as airflow, pressure, operating hours and application.
What is an oil-flooded screw compressor?
An oil-flooded compressor uses oil during compression for lubrication, cooling and sealing. The oil is subsequently separated from the compressed air and circulated back through the system.
When should I consider an oil-free compressor?
An oil-free compressor may be appropriate where the compressed air must meet stringent oil-contamination requirements. Pharmaceutical, food, healthcare and certain sensitive manufacturing applications may require this type of system.
Is a VSD compressor suitable for every application?
Not necessarily. A VSD compressor can be useful when air demand changes frequently, but the expected load profile should be evaluated before selecting one. Compressor sizing should be based on actual plant requirements.
Does Hiraba Engineers manufacture and export screw compressor spare parts?
Yes. Hiraba Engineers manufactures and exports a range of screw compressor spare parts and replacement components. Customers can share the compressor model, part number, drawing or sample for evaluation.
