Our screw compressors are designed to be installed and operated at a low cost. Supporting customers and providing sales and after-sales services is the belief and work policy of the compressor team of Havayar Company.
If your operation requires a constant supply of compressed air, you should consider a screw compressor. Unlike reciprocating compressors, screw compressors are used for any operation that requires a 100% continuous duty cycle and are designed to operate reliably for long periods of time.
Screw compressors are a great alternative to reciprocating units and come in many types depending on your needs and budget. One of these options is the possibility of integrating dryers and different filters in the package, which is used for consumers who need dry and quality air according to the ISO 8573-1: 2010 standard. Click here for more information on the air quality standard.
In addition, in small packages, the tank can be mounted on top of the screw compressor , which allows for additional storage and, together with the built-in dryer, makes it easy to install. If you have limited space at your workplace and want to save on your installation costs, this screw compressor is ideal. Depending on your budget, there is a screw compressor for you.

At Havayar, we are with customers in the initial design and production of screw compressors, usually in the smaller KW / HP range, to the production of variable frequency compressors. Of course, variable speed systems are more expensive, but typically offset the initial costs by saving energy. Variable speed screw compressors are a great option for all equipment with current fluctuations. This is especially true when you have multiple facility movements during the day and where the flow demand increases and decreases during the day. Considering that compressed air consumption can be costly and account for more than 70% of the total electricity cost, using variable speed technology can help you achieve 35 to 50% savings. Variable speed air compressors correspond to the amount of flow required. In simpler terms, the screw compressor can sense the amount of current used and adjust its speed accordingly, to allow only the required air to escape. Variable speed air compressors (VSDs) benefit many customers from annual energy savings and the ability to reinvest money in other assets.

Types of oil screw compressor

  • Constant speed screw compressor
            In this model, the screw compressor has a constant output current due to the constant speed, and is suitable for systems that require a constant             compressed air flow.
  • Variable speed screw compressor
            In VSD screw compressor models, depending on the amount of compressed air consumption in the system, the idle speed is increased or decreased,             which prevents energy wastage in the system.

How to transfer power in a screw compressor

  • Power transmission in oil screw compressor is possible in three forms, direct coupling, belt and gearbox, each of which is designed and manufactured according to customer needs.
  • Power transmission in direct coupling models is possible with coupling.
  • Power transmission in belt models is possible by grooved pulleys and belts.
  • Power transmission is possible in gearbox models with gears.

Routine series compressors

Intelligent and special control system
HY series compressors have an electronic control panel that can be programmed.
Ability to work at high temperatures
Special design with all the necessary facilities and equipment, the operation of this series of screw compressors in environments with a temperature of about +40 degrees Celsius guarantees, and if the need for operation at higher temperatures, a special design will be performed.
Simple and fast installation
The HY series screw compressor is designed to be installed easily, without the need for foundation and at the lowest cost.
Design in accordance with environmental standards
Environmental standards in the process of manufacturing and equipping air compressors are fully observed, so that the use of recyclable materials is a priority.

Less repairs and lower maintenance costs
The use of quality parts from reputable manufacturers has minimized repair costs.
Equipped with noise pollution prevention equipment
 The sound equipment installed in this set greatly reduces the volume of the device and allows the installation of the screw compressor outside the usual spaces (rooms for screw compressor device) so that this set can be installed directly in Installed the work area.
Small size and easy setup
The size of the internal components and their location on the chassis is such that this screw compressor has the smallest possible dimensions of its kind. For easy access to all related fittings and pipes, the derby is located on one side of the device and the main frame of the device has a special slot for easy transport and movement by forklift. The small size of the device allows the device to enter from ordinary and standard interventions.
High support for sales and after-sales service
Customers support is at the center of our company’s mission and service from sales to after-sales service is part of Havayar's beliefs and work policies.
