Feature  for GREAT low pressure screw air compressor:
 

1) The exhaust pressure 3.5 ~ 5 bar low pressure screw air compressor products;

2) Regular air compressor running under low pressure, the biggest risk is the big fuel consumption and bad lubrication problem, our company through a specially designed successfully solved this 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 intuitive understanding that energy-saving features of the unit:

No.	Item	8bar machine	6bar machine	3.5bar machine
1	capacity	42.1(actually  test)	43.2(actually  test)	43.5(actually  test)
2	Unit input power	274kw	238kw	187.5kw
3	Power need for compressed each cubic 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 24hours	2076kw*h	1212kw*h
6	Electric saving cost per 8000 hours	USD$83879	USD$48970	Industrial electric cost$0.12/degree

Note: take 40 cubic meter for example, the same air end is tested at the same speed.

From the above table, it can be concluded that the operating 0.35 Mpa 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 should mainly recommend the low pressure screw air compressor
