ETR has independently developed an integrated vacuum pump unit composed
of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve,
pipe fittings and an electrical control system.
It is a simple, safe and reliable device that continuously serves the
wards all day long, without occupying the ward space. The negative pressure is
sourced from the vacuum pump unit.

Duck rearing technology
A look at the appetite: When feeding, the ducks quickly gathered in the side of the trough, indicating a strong appetite, can be fed more properly. Second, see the duck weight: during the production of duck weight still maintain the original level, indicating that the material is reasonable. If the weight is too heavy or too light, the feces should be adjusted three times: the duck's normal excrement is like a strip, not a sticky one. The color of the feces is related to the type of feed fed. If the stool is white or light yellow, it means that the concentrate feeds too much, it is green when more green feed is fed, the animal feed is fed too much, and the stool is brown. These are normal feces. If there is loose stool, sticky odor, red, tan faeces are abnormal feces. Look at leisurely water: Ducks do not want to go into the water, or ducks hang up on the shore after they get into the water, and their bodies tremble. This is a sign of a drop in egg production. They should feed more animal protein feed and cod liver oil and other vitamin feeds. Fifth, look at the amount of eggs: the nutrition in the feed is balanced, the water supply is adequate, and the environment is suitable. If the eggs are large enough, otherwise the eggs are small, the feeding and management level should be adjusted according to the weight of the eggs. Six to see the feathers: duck feathers bright, close to water, indicating that proper nutrition and good health. If feathers are unkempt, wings are hanging down, and walking is weak, high energy and high protein feeds should be properly fed. Seven to see the eggshell: duck shell thin, with trachoma, or rough shell soft, indicating that the lack of calcium in the duck material, or improper ratio of calcium and phosphorus should be added calcium powder, bone meal and so on.
