5 hp rotary screw air compressor is usually single-phase. So you can use it with 220V/ 230V/ 240V 50HZ or 60HZ. Por supuesto, we can also customize the three single. We are manufacturer and can supply good price. This small screw air compressor has many merits. En primer lugar, este 3.7 kw screw air compressor is small and light. So it’s easy for us to move. En segundo lugar, the noise is lower than other air compressors. It’s quiet. You can use it indoors. Además, the exhaust air quality is high. The oil content is low. So it can meet requirements for clean air.

(1) Low noise & quiet

The measured operating decibel is 65±3dB. The vibration of the integrated compressor airend is <1mm/s. So meet the requirements of indoor use.

(2) Low consumption & el ahorro de energía

We adopts IE4 first-class energy efficiency motor. The ratio of pressure and air production bases on the golden ratio. The start and stop of air compressor are all automatic design.

(3) Safe and easy to maintain

The oil filter and oil separator adopt the inner hexagonal design. And the 5 hp screw compressor airend is truly one-piece casting. Safe and reliable. Además, the maintenance labor cost is low. And the maintenance is simpler and more convenient.

(4) High quality PM motor

We use the automotive-grade N38UH high-grade permanent magnets. The permanent magnet can withstand high temperature of 180°C. And the protection level is up to IP67.

(5) 7 inch touch screen

The touch screen can protect and monitor our air compressor in all directions. It has start-stop control for the motor. Además, es fácil de operar.

(1) Discharge pressure and air flow

The pressure in most industries is 8bar. The textile industry is generally 5bar. The rated air flow of compressor is preferably 10% greater than the actual demand. Sometimes the air consumption is relatively large. But the exhaust volume of our air compressor is relatively small. Once it is running, its exhaust pressure will often drop significantly. This makes it impossible to push mechanical equipment.

The common method is this: choose an air compressor with a smaller volume and connect it in parallel. Get more air flow. It is not only beneficial to the power grid, but also saves energy. Por ejemplo, your pressure is 8 bar. And the air flow of the compressor you need is 1.5m³/min. So you can buy 4 sets of 5 compresor de aire de tornillo rotativo hp.

(2) Working environment of air compressor

A veces, the air-use field is relatively narrow. En este momento, the air compressor should be smal in size. Además, some working distance is relatively long. So it needs to move the air compressor frequently. Then you need an screw compressor with wheels. Many workplaces are also indoors. De este modo, many air compressors are not suitable. Because they are very noisy. But our air compressor has low noise. It can be used indoors.

(3) Compressed air quality

This is also a key factor. Compressed air is generally oily and watery. Some companies have strict requirement for this. Por ejemplo, the food and medical industries stipulate that the air must be oil-free. So need use a completely oil-free air compressor. Además, environmental protection companies have relatively high requirements for air moisture content. Then you need a refrigerated dryer. En este momento, you can choose our screw compressor with air dryer.

(1) Lubricant oil replacement

We must check the amount of lubricating oil frequently during use. If the oil level is too low, it should add in time.

How to inject lubricating oil?

Firstly stop the 5 compresor de aire de tornillo rotativo hp. Wait for the internal pressure to be released. Then pull down the main power switch when there is no pressure in the system.

Open the filler port. And add an appropriate amount of cooling lubricating oil.

Pay attention to the amount of oil when refueling. The oil level should be between the z lowest and z highest oil levels. Not too much and not too little. If there is too much oil, it will affect the separation effect. If there is less oil, it will affect the lubrication and cooling performance.

For a new air compressor, need to replace the oil after 500 horas. And also need to replace every 2000 hours thereafter.

(2) Oil filter replacement

Con el tiempo, the oil filter will also become clogged. When changing the oil, should replace the oil filter at the same time. Sin embargo, in places with harsh environments, the replacement cycle should be shorter.

Specific replacement steps:

① Primero, start the screw air compressor. Run for about 5 minutos. Raise the lubricating oil temperature above 50°C. En este momento, the viscosity of the lubricating oil will decrease.

② En segundo lugar, stop the 5 compresor de aire de tornillo rotativo hp. Wait the internal pressure decrease.

③ When the internal pressure is very low, connect the oil receiving device. Open the oil drain valve.

④ Wait until the lubricating oil is basically exhausted. Then close the drain valve.

⑤ Use a special wrench to reverse the oil filter element. Remove the oil filter. Drain the lubricating oil in each pipeline at the same time.

⑥ Replace the oil filter with a new one. Screw back the oil filter seat.

⑦ Finalmente, open the filler plug. Infuse with new oil. Keep the oil level within the range of the oil mark line. Tighten the oil filler plug. Check for leaks.

Q1: What’s the max pressure of your 5 compresor de aire de tornillo rotativo hp?

A1: The pressure range is relatively wide. And the max pressure is 12.5 bar.

Q2: Can you customize the color for the air compressor?

A2: Seguro. But there is 10 sets MOQ for color customization.

Q3: How about the manufacturing time of your compressor?

A3: En general, it takes about 20 days to manufacture. Por supuesto, if you want to customize it, el tiempo será un poco más largo. Por ejemplo, if you need 60HZ or color customization, it will be about 30 días.

Q4: What are your shipping terms?

A4: We accept all kinds of shipping terms. Por ejemplo, we can send the air compressor to your forwarder (FOB). And we can also send the machine to your company with taxes and customs clearance (DDP).

Q5: What’s your 5 hp rotary screw air compressor price?

A5: We are factory. So we can provide you good price. And pls contact us for quick quotation. Gracias!
