Large industrial air compressor can supply sufficient air volume. This is 110kw 150 hp rotary screw air compressor. Its air flow is 741 cfm @7bar. So if you need 700 cfm screw air compressor, you can choose it. This large volume air compressor has wide applications. For instance, we usually use it for electronic, painting, machinery, metallurgical , sandblasting, plastic industry, וכו.

Lingyu is a reliable factory of large volume screw air compressor. Our price is not only advantageous, but also the equipment performance is stable. יתר על כך, we has strong customization ability. Hanbell, Baosi, Rotorcomp airend are available. חוץ מזה, we can supply different special voltages and languages. And color and appearance accepts special design.

This machine is variable frequency drive screw compressor. So it has many advantages acting as VFD air compressor. חוץ מזה, Lingyu is top rated manufacturer of large industrial air compressor. We supply reliable quality and strong OEM service.

(1) 110KW 150 HP screw VSD air compressor is energy-saving

בדרך כלל, the equipment cost of power frequency air compressors accounts for almost 8%. The cost of energy consumption is almost 85%. Variable frequency air compressor is different. Its machine cost ratio is a bit higher (על אודות 10%). למרות זאת, the energy cost ratio is only about 50%.

Fixed speed screw compressors frequently load between 6~8 bar. Actually, it only uses 6 בַּר. So there is extra 2 bar frequent climbing. It will result in 14% more air compressor consumption. For each1 bar climbing, על אודות 7% more current will be consumed. We assume a actual accumulation of 70% of frequent climb. Take the 110KW 150 HP rotary screw air compressor as an example. The machine runs 8000 hours each year. And calculate the electricity fee at 0.7CNY/kWh. Now we calculate the energy consumption of large industrial air compressor.

Excessive electricity charges generated by frequent climb:
70% loading time*(110KW*14%)*8000 hours*0.7≈60300CNY/year.
(If it is an VSD air compressor, it always exhausts compressed air at a stable pressure. לָכֵן, there is no loss of this part.)

Electricity fees for the unused part:
30% unloading time* (loss 110KW*40% no-load loss)*8000 hours*0.7≈73,900CNY/year.

Three-year power saving of 150 HP large volume air compressor far exceeds its purchase cost:
(60300+73900-inverter power consumption 3%*110KW*8000 hours*0.7) *3 years ≈ 347,100 CNY.

(2) High quality configuration

① Microcomputer control: simple button type, constant pressure and temperature design. Real-time monitoring of various data of large industrial air compressor.

② Centrifugal impeller: low noise, side air intake with high wind pressure, top exhaust.

③ Filter: high-efficiency filtration, long service life.

④ Oil and gas separation barrel: with good flow and structural design. Oil content≤3ppm.

⑤ Intake valve: high-sensitivity intake valve control. Large channel, low resistance intake valve.

⑥ Air filter element: Imported molecular filter material. High filtering precision.

⑦ Compressor host: large rotor, low speed. לָכֵן, our large volume air compressor has high reliability.

⑧ Permanent magnet motor: low speed and high torque. Independent fan cooling ensures stable operation of the motor.

קוֹדֶם כֹּל, it is necessary to determine the working pressure required by the air-use end. Add a margin of 1-2 bar. Then select the pressure of the large volume air compressor. סוף כל סוף, determine the corresponding air flow. When determining the flow rate, you should first know the air flow of all air-consuming equipment. Multiply the total number of flows by 1.2. Assume that the paint factory uses about 15 CFM @10bar per person. Once you have determined the desired CFM, multiply that number by 1.2. And use the total CFM to select your compressor. לדוגמה, there are 30 mechanics. Then the total flow is 30*15 CFM x 1.2 ≈ 540 CFM. So you can choose a 110KW 150 HP rotary screw air compressor.

שאלה 1: What’s the cfm of your 150 hp rotary screw air compressor?

A1: This 110KW screw compressor belongs to large volume air compressor. If pressure is 7bar, the air flow is about 741 cfm.

שאלה 2: How long is your delivery time for this large industrial air compressor?

A2: If you only regular machine, the production time is 25 ימים. But if you have special requirements for color or voltage, the time will be a bit longer. It’s at least 45~50 days.

שאלה 3: How long is the warranty time for your large volume air compressor?

A3: All our industrial air compressors have same warranty time. The whole equipment is 1 year. And compressor airend is 2 שנים.

שאלה 4: What spare parts should I purchase with the machine?

A4: Our large industrial air compressor has stable performance. But all screw air compressors contain some consumables and wearing parts, such as air filter, oil filter, oil separator, valves, וכו. So you can buy some of these accessories together as a backup.
