EF 25 ~120 Series Air Filter
Product Overview
EF 25 ~120 Series Air Filter is a tank breather FILTER, installed on the fuel tank or hydraulic oil tank of the hydraulic system. This FILTER balances air pressure inside the tank while blocking dust, moisture and debris in ambient air, to keep hydraulic oil clean and avoid pollution entering the oil tank of different kinds of Machine. It is widely used for hydraulic reservoir air replenishment, preventing particle contamination and oil oxidation.

Working Principle
As a vital breather FILTER for the hydraulic system, when the hydraulic oil level rises and falls inside the reservoir, air flows in and out through this unit. Dust and solid particles in incoming air are captured by the filter media. The built-in anti-splash structure stops hydraulic oil from splashing out of the tank. It maintains normal pressure balance inside the tank, protecting the whole Machine from contamination caused by dirty air.
Core Advantages
1. Compact tank-top installation design, easy assembly for the hydraulic system.
2. Multiple models from EF25 to EF120 to match different tank volume and air flow requirements of Machine.
3. Dual functions: air ventilation and dust filtration, with oil splash prevention.
4. Simple structure, easy to inspect and replace the filter element of this FILTER.
5. Good corrosion resistance, stable performance for outdoor and workshop working conditions.
Application Range
This EF series FILTER is commonly mounted on the oil tank of the hydraulic system for construction machinery, machine tools, metallurgical equipment, injection molding machines and other industrial Machine. It serves as hydraulic tank air breather, protecting hydraulic oil from airborne contamination.
