1. European Design
The series screw compressor has unique double air ducts separated by the central sound insulation board inside the air end,one for exhaust of air which is from and sucked by fan into the direct air cooler, the other one for exhaust of air which is ducked into the rear parts of main motor for cooling the motor. As a result, therer are two rear air inlets and two front exhaust outlets and two front exhaust outlets. Such structure encloses inside the air end, making the low noise level of air compressor in the compressor industry.
2. Feature
The design Features of the air ends
Main machine is from the company named LOFTOLL in Germany.
Our technology is using the third era non-symmetry tooth-model rotor in 5:6,
the distance between rotor we keep in 0.003 inch, it will have no abrasion for ever,
the fall in tooth of rotor is very small, cost of circumfluence is small, then it will be in
higher effort than 4:6 about 10-20%, reduce electricity about20%. We use SKF bearing
from Sweden, which prolong the life of main machine. Our machine can work continuously in 24 hours.
Low consumpition and high efficiency motor which is mewly special designed
1,Y-△starter; Voltage 380V; Frequency 50Hz; Protection Ip-54; Insulation Class F
2.A new generation of energy-saving motors developed and produced by ourselves
which has optimized the parameters of the motor windings by adjusting the relevant
dimensions of the motor. The imported materials are improved, and the average
efficiency is improved by 1.9% .The indicators meet the national two energy efficiency standards.
Imported air capacity control system
Intake control valve on the displacement of 0-100% of the stepless adjustment,
so that the amount of air supply consistent with air need, energy-saving effect more better.
Minimum pressure valve to ensure the maintenance of the body lubricating oil pressure required
to reduce the oil separator air flow, the oil and air separation better, and has the function of check valve.
Imported filtration system
Filter: We choose LOFTOLL from Germany, specially designed, can be used more than 4000 hours, it is easy for maintains and change.
Oil-filter: We choose LOFTOLL from Germany, filtration density is 10μm, it can filtrate 99.9% impurity from oil, in order to protect compressor and bearing. It can be used more than 4000 hours.
Air-Oil separator: We choose LOFTOLL from Germany, after separator, the oil is under 3ppm, to ensure the quality of air.
Configuration of differential pressure sensor, when the filter block, before and after the pressure exceeds the set value, the automatic alarm to remind maintenance or replacement
Impoved advanced microcomputer controller which is powerful at troubles diagnosing and protection.
All parts are from Schneider in France, using full intelligent computer control. Easy, steady for customers.
Introduction: Full-automatically load and unload, control the input air full automatically, compressor will start when there is no pressure automatically, and will stop working when the pressure is full in air tank, when the compressor is short of electric ,the electric is in reverse, the pressure is too high, the temperature is too high, it can protect itself full-automatically. You can use our compressor without any workers on duty.
