EF 25〜120 Breather Filter Series
The hydraulic air temperature cleaner produced by our company is a new type of hydraulic accessories, which have eight specifications. The structure of this product is made up of two parts: the air is too warm and the oil is too warm. It can not only prevent particles from being mixed in the process of refueling, thus simplifying the structure of the oil tank, but also beneficial to the purification of oil.
Compared with non-metal superheater, the product adopts copper-base powder metallurgy sintered superheater, which has the characteristics of stable overtemperature precision, strong strength, strong plasticity, convenient disassembly and washing, and can withstand thermal stress and impact and work normally under high temperature, etc. Over the years has been used for many hydraulic system oil slightly matching.
This kind of series has 8 models. It includes oil filtering and air filtering. EF series filter incorporated with oil filling is widely used in the tank of hydraulic system. Filter element is made of sintered copper powder, which is robust in const ruction, stable infiltration and resistant to high temperature. The oil level will rise or drop during the operation of hydr aulic system. When the oil level rises, the air will be expelled from inside. When the oil level drops, the air will be inbre athed from outside. The breather filter can be installed directly on the tank cover to filter the inbreathed air. It also can be oil filter. When injecting the oil into tank through this breather filter, the contaminant will be filtered. Breather filter can keep the tank clean and also balance the pressure in the tank. It prolongs the service life of the components.
When the hydraulic system works, the oil surface sometimes rises or falls, and rises from the inside to the outside.
Expel air, taking in air from the outside as you descend. In order to purify the oil in the tank, the oil is slightly covered
The vertical air dripper is installed on the board, so the air inhaled can be overheated. At the same time, the air drain cleaner is the oil injection mouth, and the new working oil injected must be filtered and then entered the tank, so as to drop the dirty particles in the oil.
In the hydraulic system, the purification of working oil is a very important link. The air leakage cleaner can keep the oil in the oil tank clean, not only can prevent the dirt particles from entering the oil tank from the outside, but also can prolong the working cycle and service life of the oil and components, so as to ensure the normal operation of the hydraulic system. In addition, when the hydraulic system works, the air drain can maintain the balance between the pressure in the oil bit and the atmospheric pressure, so as to avoid the possibility of cavitation in the pump.

If the fluid is water一glycol, the model of this breather filter is EF3-40 . BH
Note:
1. The air flow rate listed in the table is the value of air flow rate of 15m/s.
2. For example, EF1-25, 1 refers to the representative model, and 25 refers to the overheated air caliber and the refueling caliber of 25mm.
3. The air overheated sheet adopts copper based powder metallurgy.
Over the years my company with the relevant scientific research units and manufacturers of hydraulic air temperature clear technical performance were tested, the conclusion is: the hydraulic air temperature qing wares work air flow rate, the more we di, the fouling thermal resistance is better, therefore, when choosing liquid pressure air temperature qing wares should have a certain margin, the amount of air flow for the pump is generally selected row about 1.5 ®.
