Ensuring the quality of the discharged air

The presence of special filters at the oil-free screw compressor’s outlet assures you that not only the discharge air is free of oil, but the discharged air is free of any germs and bacteria and you can employ it safely.

Variant speed according to the required conditions

Air compressors have the ability to adjust the speed with the required compressed air delivery. This ability helps to provide the continuous flow and enhances energy efficiency.

  • Absence of fluctuations in the outlet stream pressure
  • High quality of the exhaust air and lower operating costs

Easy and convenient setup

By the advanced monitoring system, all parameters can be regulated according to the operational requirements.

Low noise system design

Our systems are designed in such manner that the minimum noise is produced and leaves the boundaries of the system. In this regard, a muffler is applied to reduce the noise in the inlet and outlet openings.

Reducing maintenance costs

As their name describes, oil-free screw compressors are free of oil which causes low maintenance cost of the product.  It also should be noted that the device does not require many visits, as well as changing and recharging the oil.

Lowering operational costs

  • discharge filter’s lifetime increment due to the absence of oil droplets in the outlet stream.
  • Reduction of oil consumption which causes no need to continuously charge the compressor’s oil tank
  • Decrement of operational costs related to the energy which comes from the lack of pressure drop in compressor output filtration

Other features of oil-free screw compressor

  • designed for minimum space occupation.
  • Very low vibration and no need to implement a special foundation
  • Increased capacity in proportion to the shell size due to the capability of enhancing the rotors rotational speed.
  • High speed compressors, which is the result of the absence of oil and also the lightness of the rotors
  • The ability to pressurize various type of gases other than air, such as polymer gas and dirty gas
  • employing a fluid compatible with compressed gas like water for cooling it.

Oil-free screw compressor

Knowing the air quality industrial standards and the permissible amount of impurities represented in each standard class as a key parameter can ensure providing high quality air in critical applications. The lower the class number, the purer the air should be.

ISO 8573-1: 2001 is the international standard for assessment of the quality and purity of compressed air based on related amount of impurities such as dispersed particles, water and oil.

In this standard, the zero class specifies the air quality in critical industries such as food and beverage, pharmaceutical, textile and electronic industries. This is the strictest class, covering oil impurities in the form of aerosol, vapor and liquid form. Some manufacturers have released their products in the market as oil-free, but this is not necessarily the case. If you need guaranteed clean air, HAVAYAR can meet your needs.

Frequently Asked Questions

In many compressors, air compression occurs in the air- end in the vicinity of the oil. The presence of oil droplets in the compressor discharged air is an obstacle in some industries due to its proximity to the product and the risk of contamination (food, pharmaceutical, textile and dyeing). On the other hands, it adversely affects the pneumatic performance of instruments (oil and gas, power generation and etc.) which can be destructive. In this regards, supplying free of oil compressed air by oil-free compressors is always very crucial in large industries.

In terms of capacity, the oil-free reciprocating compressor has the lowest capacity and the oil-free centrifugal compressor has the highest capacity at different discharge pressures among others.
