Product Use of Electric Power Installation, Repair and Testing Dry Air Generator / Electric Power Tools
Specifically designed to provide high-purity dry air with a dew point as low as -55℃ to -70℃ for large power equipment such as ultra-high voltage transformers, extra-high voltage transformers, and reactors during installation and maintenance. It can replace traditional drying methods like hot oil circulation, nitrogen supplementation, and vacuum extraction, but is more efficient, economical, safe, and environmentally friendly.
During installation and maintenance of power equipment, it is not affected by changes in external weather conditions—even in rainy seasons, normal construction can proceed. When overnight work is required, simply seal the flanges and fill with dry air to 0.02-0.03MPa. This greatly reduces workload, achieving the effect of shortening the construction period and improving installation and maintenance quality.
Application
Using a vacuum generator as the vacuum source, equipped with a 5L vacuum buffer tank, it truly achieves oil-free, noise-free, lightweight, and odorless operation, with noise far lower than ordinary oil-free vacuum pumps. The control cabinet can freely set upper and lower limits and can automatically maintain vacuum. (Maximum vacuum can reach -85KPA, flow rate is 75L per minute)
This machine only needs to be connected to AC220V power and plug in the air pump to use. It is simple and quick to operate, can suck in ordinary liquids, and automatically blow them out of the equipment.
Automatic pressure-maintaining oil-free vacuum pump, used for vacuum suction cups, can quickly achieve stable adsorption force, then automatically maintain pressure, energy-saving and low consumption, a fast vacuum creation device with stable adsorption force.

Maximum output flow rate: 0-5000ml/min
Operating ambient temperature: 0-40℃
Operating ambient humidity: <85%
Precautions
1. Since the compressor is an inductive load, the instantaneous current during power on/off is several times higher than normal operation, making it easier to blow fuses. An 8A fuse should be used.
2. If the compressor does not start during operation and the thermal overload relay activates, it indicates the compressor temperature is too high. It will automatically return to normal after cooling.
3. To avoid excessive water accumulation in the machine affecting air purity, press the drain switch for a few seconds before each shutdown. (You can connect a plastic bottle to the drain outlet to prevent water splashing), and drain at least once a day.
4. Observe the color-changing silica gel through the observation window. Users can replace with new silica gel or perform drying treatment as needed.
5. To ensure gas purity, the activated carbon needs to be replaced every 1000 hours of operation (activated carbon is 20-40 mesh, pencil lead type).
6. Since the compressor operates in an open circuit mode, lubricating oil will be discharged with water, causing consumption. Therefore, after one year of use, add lubricating oil to the compressor appropriately. The oil filling port is next to the compressor outlet (or can be added through the inlet), it is recommended to add 200 grams of No. 18 refrigeration oil.
7. The inlet filter needs regular cleaning (the cycle depends on indoor dust conditions, can be cleaned with ultrasonic) to keep the inlet unobstructed; otherwise, it may cause increased compressor load and heat, and if the temperature is too high, overheating protection may trigger a shutdown.
Product Features:
♦ Unique rapid regeneration technology for desiccant:
Using rapid regeneration technology, the dry air generator can provide qualified dry air after 5-20 minutes of operation. Truly ready to use immediately without waiting.
♦ Low dew point of product gas:
The core indicator is the supply air dew point; the lower the dew point, the drier the air. Low dew point dry air will absorb moisture from the transformer to improve its insulation performance. The dry air integrates compressed drying, refrigerated drying, and adsorption drying, and adopts a multi-stage filtration system. Due to the use of our company's independently developed "strong composite molecular adsorbent", regardless of the moisture content in the air, the dew point of the product gas will quickly drop below -70℃.
♦ High-efficiency filtration system:
Using "gradually denser" filtration technology, the filtration precision can reach 0.01μm, with a solid particle retention rate as high as 99.99%. The primary filter has a filtration precision of μm, the secondary filter has a precision of 0.1μm, and the tertiary filter has a precision of 0.01μm.
♦ Completely abandon adsorbent heating regeneration:
The adsorbent adopts a non-thermal pressure differential fully automatic regeneration method, completely eliminating the need for manual baking of the adsorbent.
♦ *"One-key operation" technology:
Using a PLC intelligent controller, just press the "Start" button to start the equipment, and the equipment operates fully automatically, minimizing manual operation errors.
