Our piston or reciprocating air compressor is the simplest type of ai compressors, and is widely used in small industrial units. It is economical and cost effective, and is commonly found in small workshops, body and repairing shops, tire shops and local manufacturing facilities. Air-marshal’s range of piston air compressors can be used in a variety of settings including for home-based DIY projects, small scale contract work as well as for large industrial units.

Piston air compressors do not have a continuous duty cycle and works for about 30 min for every hour of cycle. It needs a proper cooling period between cycles without which the compressor may malfunction. Despite this, it is best suited for small-scale use because small shops and homes most often do not require continuous work cycle.

Our piston air compressors come in three types: Single Stage Low Pressure Compressor, Two Stage Medium Pressure Compressor and Multi Stage High Pressure Compressor.

Screw compressor is a type of rotary compressor that compresses air by screw action. The most important component of the screw compressor is two screw-like rotating elements. The twin screw consists of male and female rotors that rotate in opposite directions while the volume between them, as well as between the screw and the casing, decreases.

Each meshing helical screw has a fixed, built-in pressure ratio that depends on the screw parameters like its length and pitch. For maximum efficiency, it is important that the pressure ratio is adapted to the working pressure required at your facility. There are no valves or mechanical forces in the compressor, and hence vibrations are minimal. Also, a specialized foundation or mounting system is not required because the screw compressor runs very smoothly.

Screw compressor or rotary screw compressor finds wide use in industrial units all across the country. We take immense pride in our high quality screw compressors that form one of our best-selling and most popular product offering. They are especially suitable if you need 100% continuous duty cycle with non-stop compressed air flow. Our quality screw compressors are long-lasting, durable and strong. Air-marshal screw compressors can be customized and adapted to your specific needs.

With Air Dryer

It is possible to attach air dryer to screw compressor, and this integration allows it to be used in varied applications which require clean and dry air.

Tank Mounted Series

Screw compressors of smaller size can be mounted on tanks that offer additional storage capacity and can be used in plug and play applications. These screw compressors are suitable if you have limited space at your facility, but require good storage capacity along with air dryer function.

Variable Speed Drive

Air-marshal Variable Speed Drive compressors suit industrial facilities where there is fluctuation in demand for compressed air flow. Examples include industrial units that function in shifts and have varying cycles of activity. We are proud of our Variable Speed Drive (VSD) screw compressors that are widely preferred due to the excellent savings they provide in terms of low power consumption. This could very well translate into annual savings of several thousand dollars. The compressors have powerful sensors that detect the drop in demand, and adjust motor and elements speed accordingly. This reduces compressed air supply and adjusts output to meet demand. VSD helps avoid unnecessary waste of electricity, keeps your operations environment-friendly and sustainable, and saves cost.

Benefits of VSD

• About 80% of a compressor’s operating cost is energy consumption, with VSD you can achieve up to 35% of operating cost in energy savings
• Lower system pressure is possible when compressed air demand is down
• Flexible pressure selection where it is possible to start/stop without having to unload
• No idling time or energy wasted
• Low system pressure avoids leakages

Our VSD screw compressors have gained in popularity due to the savings they offer business owners who operate small and medium size industrial units.

Compressed air is a critical utility in manufacturing facilities, next only to water, electricity and natural gas. At times, the compressed air needs to have less moisture content.

The Air-marshal dryers provide dry air that is more sanitary to workers, and is beneficial to both manufacturing process and products alike. This makes air dryer a critical component of your air treatment system. Air-marshal compressed air system offers you all the capabilities and helps make the production processes viable and business goals achievable. Heatless and Refrigerated air dryers are our most widely used types.

Key Benefits

• Ensures high quality air where all contaminants are removed through multi-level processes
• Low maintenance due to simple design and uncomplicated processes
• High durability of components
• Saves energy through optimal design
• Easy to monitor and operate

Heatless Air Dryer

Our meticulously designed heatless air dryer is a simple and efficient way to provide industrial units with clean, dry and compressed air. The atmospheric air is passed over regenerative adsorbent material to fully remove moisture and provide high quality, dry and oil-free air to facilities. The resulting compressed air not only reduces chances of corrosion in the industrial unit but also does not harbor microorganisms. Air-marshal dryers give you the maximum value for money and are the best option to achieve an optimal air system in your facility.

Twin desiccant towers are used in the heatless air dryer system where a portion of the dry air flows from the online drying tower to the offline regenerating tower. Regeneration is the removal of accumulated moisture from the desiccant and is also known as purging. The dry air attracts the moisture from the desiccant and exhausts into the atmosphere.

Refrigerated Air Dryer

Air-marshal Refrigerated Air Dryers are energy efficient and superior performers. You can be guaranteed of reliability, efficiency and convenience when you choose an Air-marshal Refrigerated Air Dryer.

In refrigerated air dryer, the warm and moist incoming air is first cooled in air-to-air exchange. Some of the moisture is removed by condensation and the cooled air is then cooled further through air-to-refrigerant exchange. The remaining moisture is removed by condensation and drained away. The outgoing cold air is then warmed again through air-to-air exchange to ensure safety of equipment and/or products.

Filter

Filter provides high filtration rate to 5 micron so as to remove dust and impurity efficiently.

If you want to have the most beneficial and optimal air system in your facility, an Air-marshal air receiver is the most essential to you. Air receiver is also known as compressed air tank and acts as a temporary storage for compressed air when the demand comes down in the industrial system. As demand peaks, the Air-marshal air receiver will be able to accommodate the demand and the compressed air system functions optimally. An air compressor installation without a storage tank will have longer loading and unloading cycles leading to wastage of electricity and operational inefficiency.

Smaller compressors can be mounted on air receivers and is very much suitable for facilities where there is shortage of space. Mounted compressors save on installation costs and you also do not have to invest in a standalone dryer.

Air-marshal air receivers give you many benefits. Some of these are as follows:

• Minimizes fluctuations in air pressure demand
• Helps cope with sudden increase in compressed air demand
• Gives substantial energy savings
• Maintains stable compressed air environment and ensures safety of products, processes and equipment

Air-marshal Auto Drain Valve employs the latest in auto drain valve manufacturing technology. When the level of the condensate collecting in the drain valve reach a particular level, the valve opens and drains it out. The condensate sensing mechanism ensures that there is absolutely no loss or wastage of compressed air. Timely and efficient working of auto drain valve ensures considerable savings in terms of time, electricity and money.

Air-marshal after coolers are heat exchangers that cool the discharge from an air compressor. They use air or water to remove moisture from compressed air system. The moisture or water vapor in the compressed air is condensed into liquid form and is drained out. Seperators and after coolers play a very important role in ensuring compressed air stays moisture free.

Benefits:

• Moisture-free air ensures corrosion-free environment for equipment
• Long-lasting and easy to maintain
• Low on cost and high on value
