Product Description

The GREAT  Low-Pressure Screw Air Compressor there are different models to choose from: the motor power from 90kw to 220Kw, the working pressure from 3.5Bar to 5.0Bar, the flow capacity from 20m³/min to 57.5m³/min. We can also customize according to your needs. It is very suitable for the industries which is requiring low working pressure(0.35~0.5Mpa) but large air flow capacity. 

A. The Picture for Low-Pressure Screw Air Compressor:

B. Products Introductions & Advantages for Low-Pressure Screw Air Compressor:
This seriesof air compressor is independent designed by our company, we has the  core technology. The product has stable operation, the distinctive features of reliable performance, energy saving, tailored solutions for special customers gas demand. 
Low pressure screw air compressor:
1. The low-pressure screw air compressor of our company has been specially optimized for the exhaust pressure of 0.35~0.5Mpa.
2. The operating pressure of the conventional screw air compressor is mostly between 0.7~1.5mpa, if it running in the low-pressure interval (0.35~0.5mpa) for a long time, the biggest risk is the big fuel consumption and bad lubrication problem, But the low-pressure screw air compressor of our company can successfully solve these two problems.
3. The biggest advantage of a low-pressure machine is: on the premise of meet the user's gas pressure, can with the lowest power consumption to achieve the biggest gas demand, to achieve energy saving!  

By following a set of data, you can intuitively understand that energy-saving features of the unit:

No.	Item	8 Bar machine	6 Bar machine	3.5 Bar machine
1	Capacity (m³/min)	42.1 (actualy test)	43.2 (actually test)	43.5 (actually test)
2	Unit input power	274KW	238KW	187.5KW
3	Power need for compressing each cubic meter air	6.5KW/m³/min	5.5KW/m³/min	4.3KW/m³/min
4	Electric saving per hour	86.5KW·H	50.5KW·H
5	Electric saving per 24 hours	2,076KW·H	1,212KW·H
6	Electric saving cost per 8000 hours	USD 83,879	USD 48,970	Industrial electric cost $0.12/degree
Note: Take 40 m³ for example. the same air end is tested at the same speed

From above table, it can be concluded that the operating 0.35Mpa pressure gas equipment, and if using the air compressor of pressure of 0.6-0.8Mpa, the user needs to increase the electricity cost by USD$45000~$80000 per year. Therefore, in the low-pressure gas industry, such as glass industry, textile industry, and foam plastics industry, considering the running cost, we recommend to use the low-pressure screw air compressor.
